A hotter display has a higher chance of burn-in, LG says

[sonic meadow]

standalone headsets have active cooling because they have an sbc wedged in the middle of a dense plastic housing

[mossy gull]

I only have displays, I kinda never owned an HMD

[sonic meadow]

my vivepro has been sitting for an irritatingly long amount of time unused. still not sure if the... ~2k was a good idea or not

[mossy gull]

What about the 8K Pimax

[sonic meadow]

well I dont have one of those 😛

[jade scaffold]

Yea the vive pro was really expensive for what it was

[sonic meadow]

it was even more expensive here.

a friend (when he was in aus) bought an index (imported probably), and also imported two compatible wireless units becuase it was cheaper than buying one locally

[mossy gull]

Me neither🙃

[pearl moon]

I phrased it wrong, but what I meant is a software like OculusKiller that guts out all the oculus stuff and optimizes it to only be a steamvr headset.

[mossy gull]

I hate you need to log into an HMD

[pearl moon]

Plus the hoops you need to jump through to do anything that requires a developer account.

which is alot

i needed to make my account a dev account if i wanted to use handtracking in DCS World for example

[mossy gull]

I mean, I don't even have a Facebook account nor do I want to make 1

[jade scaffold]

Yea because the link pass through for hand eye and face movement was in beta

I'm used to making dev accounts so it wasn't much of an issue for me

[glacial canyon]

Quick quesh, any technical/security objections regarding the use of DroidCam to use my phone as a webcam?

[cinder lagoon]

I Use xSplit Connect or IP Webcam for that purpose
Don't expect great latency, most of them provide a secure connection.

As much as I like Louis, he is not known to validate his sources all that well. Hopefully GN or someone similar does a deep dive. Its certainly shitty that Gigabyte is not covering PCB defects, but when looking at Ebay to see the scope of the issue I found Asus and MSI cards with the same story.

It seems to be a question of scale, there certainly are a lot more gigabyte cards listed as dead (about 5x as many as other vendors by my loose count), but when perusing the descriptions many of them are not PCB related

[sonic meadow]

however there could also be more dead ones available if they have sold more cards. I don't know who actually sells more

[sacred seal]

Well if most of them are from prebuilts, it could be from the assembly/ shipping of those machiens are sub par

I don't think Gigabyte has any OEM cards?

[mossy gull]

You know there's some ugly laptops that can attach watercooling, so I thought by myself, why not make my Asus Advantage Edition watercooled.
So I was thinking of a 3D printed bottom panel with a spot for a Alphacool ES Stream LGA 4677 1U and some tubes and quick disconnects.

Oh and extra fans

Bigger fans

If I have the place for it

Yes, I know, I act dumb.
But if it works well, I have a laptop that can properly overclock

And maybe sell some kits for people who want to do the same

And before you say that that block is too expensive or big, it was the only 1 flat enough with side ports that I could find

[pearl moon]

Took me a couple days to get it set up and dialed in (including a factory reset cause my brother forgot the login to his old facebook), but hot damn it is amazing.

[jade scaffold]

Yea vrs really fun

But we need more AAA type games on it

[pearl moon]

DCS is so much better with it

[jade scaffold]

We need more half life alyx type games

[jade scaffold]

MSFS is also really fun need to try dcs in vr

Left 4 dead 3 as a vr+regular title would be awesome

[pearl moon]

project wingman i've heard is a great hybrid title

Payday 2 is for sure

[jade scaffold]

Oh I only play payday 2 in vr

[pearl moon]

i'm excited to try it

[jade scaffold]

It's chaotic as hell because the games made on an engine from like the 90s

[pearl moon]

Tbf the first game to come out on it was released in 2001

[jade scaffold]

Yea and it was a quasi 3d race game

Mot a proper 3d horde shooter

[pearl moon]

I'm just glad they realized it's a shit engine and not worth using anymore

PD3 will be on UE4

I just hope it has VR, and is actually made with vr in mind instead of just tacking it on years after release.

[jade scaffold]

Yea though payday 2s tack on vr is actually very well executed

Weirdly the some of the best vr I've ever played

[jade scaffold]

hey @mossy gull sorry for le ping but you seem to know some stuffs about getting things ran at higher resolutions than a monitor otherwise would allow

Trying to run a game in VR using Reshade which is working fine however my monitors a much lower resolution than my VR headset only being 3440x1440p compared to my VR headsets 3600x1920 and to make that worse to maintain immersion im actually very close to the image thats projected which leads to me actually viewing a much smaller portion of the image. Idealy i want to use somthing akin to DLSS or FSR or what ever intels alternative is so im not nuking performance from a game that already doesnt run too good

[surreal moss]

What headset are you running?

[jade scaffold]

Meta Quest Pro

[mossy gull]

AMD has native support for it, I sadly do not know if other manufacturers have the same stuff.
On AMD it's called AMD Super Resolution

Not to mention why use something like Super Resolution and upscaling tech?
That almost sounds counter productive

[surreal moss]

Nvidia is also able to upscale although I haven’t used the feature in a few years

[sacred seal]

I presume you are running this though steam VR? If I am not mistaken the resolution settings for VR are entirely different from the monitor

I belive the occulus app has settings for adjusting the resolution of the device

[mossy gull]

Also keep in mind, I only use Super Resolution only to avoid anti-aliasing or whatever how you pronounce it

[jade scaffold]

no because this isnt actual VR its using reshade to basically split my display and using 3D image data from reshade to make the VR image look 3D so its based on monitor res

[barren juniper]

they wont fill that gap until rnda2 sells out

[barren juniper]

like if you need something mid range right now, 6700xt, or a770.

while supplies last

[pearl moon]

https://www.reddit.com/r/OculusQuest/comments/1446je4/quest_update_v54_causing_wifi_performance/ right as i get my quest 2 setup and running good

a dev who makes Virtual Desktop tweeted "literally the only solution is a factory reset... yeah we aren't kidding" and even then alot of users are saying factory reset only solves it temporarily

[barren juniper]

i have the oculus go that my dad won as the second place prize at a business conference and gave to me because he had no use for it and i have used literally twice

but yeah that sucks

[sonic meadow]

my favourite brand of laptop

[mossy gull]

That's some terrible specs, also Dell these days are mediocre

[sonic meadow]

its not new. that was a second hand auction site

and 32GB is terrible specs on a laptop?

[mossy gull]

It isn't, but the CPU is mediocre

[sonic meadow]

all it says is intel i5, that isnt enough to make any real assumptions about its quality or fitness for purpose

[mossy gull]

All I can find is it's a rugged laptop, which usually have weaker versions of certain CPU

[sonic meadow]

cool. you have looked at it more than I have. I saw a funny typo when scrolling past an posted it

[mossy gull]

My brain autocorrects things, so I rarely see spelling mistakes unless I focus on it

[sonic meadow]

fair

I have been on and off looking for a replacement laptop (mines went and died months ago), so have been lingering on them for a bit longer than I would have otherwise

[surreal moss]

drops Dell Latitude in a pelican case
I dub thee an Attitude

[jade scaffold]

yea not much of an issue if you are using it through cabled link but a big isssue if you use virtual desktop/ALVR or Airlink

[cinder lagoon]

Discord asked me to change my name today. Instead of Chaos_02#5921 I am now the one and only chaos_02 😁

[cerulean helm]

Okay need some help here. Just went and bought 2 LG 27GP83B monitors and have run into some weird problems, already exchanged one as I believe it was defective.

Problems:
Screen one one monitor randomly turns black (no power loss or disconnect sound made) 3 or 4 times then returns. Swapped DP cables, no change.

Monitor I returned the screen turned green on me and stayed green even after recenting the vido driver (also reinstalled gpu driver just to be safe).

Replacement monitor plugged into same DP port on my GPU green screen, swapped to 3rd DP port on GPU and screen is normal, but the random black screen issue remains on the display that is picked as my main monitor.

[cinder lagoon]

Sounds like a defective monitor batch. Does this behaviour happen with other monitors or other refresh rates (or HDR modes)?

[cerulean helm]

So far I have had the random black screen happen to both monitors, though not at the same time, and I think its only when its set as my main monitor but can't be sure.

I dropped the refresh rate from 165 to 144, and that seemed to work but after I manually reinstalled the monitor drivers it started happening again. My monitor calibration also stopped working as I did this.

Just now, I recalibrated the replacement monitor (I use a DataColor Spyder Pro) and haven't seen a black screen yet.

[mossy gull]

What GPU do you have?

[cerulean helm]

3080
I'm going to grab some DP 1.4 cables tomorrow as I don't have any spares. Though it would be weird that both DP cables from the monitors would be faulty.

[mossy gull]

Did you have any LG or Samsung display before getting this particular LG?

[cerulean helm]

No, my previous monitors are Acer Predator xb271hu which released in 2016.

[mossy gull]

Sorry if I come and go, I personally have seen some trouble between LG/Samsung and NVidia cards.

It looks like a handshake protocol problem.

You can change display all you want but it won't change the turn on/off constantly.
You can try a completely different model display.

This is my personal experience but I seen this happening between a Microsoft GTX 1060, Dell RTX 2070, Gigabyte RTX 3070 and the LG C1 and 1st gen Samsung Super Ultra Wide.
I haven't seen this problem yet with AMD Vega FE and AMD RX 6700XT.

You can vaguely fix it with a so called Active DisplayPort or Active HDMI.
You can recognise these cables by the little box in the cable.

[silk jasper]

Hey lads so long story short I have a Lenovo Yoga 7i that I have just factory reset. Prior to factory reset had 0 issues after reset we ran all the driver updates the software windows everything that needed updates to make sure it was ready for the sale we had intended for it and the touchpad has since stopped working Post factory reset does anyone have any ideas as to why this may be?

[mossy gull]

Best is to download MediaCreationTool, install it on an USB thumbdrive, and fully reinstall Windows and its drivers.

Windows 10:
https://www.microsoft.com/software-download/windows10

Windows 11:
https://www.microsoft.com/software-download/windows11

This way you'll have all recent Windows updates installed from the get-go and then you only have to download the drivers.
It also has a much lower chance to be buggy.

[cinder lagoon]

We're talking about like 400% lower chance of being buggy

[mossy gull]

Pushing through a lot of updates in a short time does corrupt files which cause bugs

[silk jasper]

Tysm

[mossy gull]

I am sorry you have to go through reinstall again

[silk jasper]

Another day in my world at this point

[timber barn]

not sure if I did it wrong but I posted this instead of asking here: https://discord.com/channels/222052888531173386/1117562574108635217

[barren juniper]

thoughts on the 5600x3d? theres some rumors floating around about it

[jade scaffold]

might actually be a pretty good mid-low budget option

depending on price

i can get a 5600g for like £110 which is really good so if the 5600x3d can be got for more like £160 or somthing that might be really good epescially for the X3Ds gaming performance

[cinder lagoon]

If the 5600X3D is compatible with X470 just as the 5800X3D it's a pretty ballin gaming value!

[mossy gull]

If they still release an BIOS update for it for X470

[cinder lagoon]

Mine is still kinda getting updates and the code would've likely been implemented in the 5800X3D bios already

[jade scaffold]

why X470

[cinder lagoon]

Cuuz its a good budget option and there's no point for going X570 or B550

[jade scaffold]

Second hand X470s really do go cheap

the new ones arent going all that cheap but the second hand ones are real cheap

[barren juniper]

if they are doing this maybe they will do a 7600x3d too like they should have done instead of the 7900x3d?

[mossy gull]

I mean I still would go for X570, especially with the newer GPUs.

[sonic meadow]

why not b550? x570 is mostly unnecessary

[mossy gull]

PCIe slots, X570 has more PCIe slots

[sonic meadow]

fair

[cinder lagoon]

Budget option is x470 (used), optimal is probably B550 (also used)

[mossy gull]

For me I need the PCIe slots, which X570 has more of

Especially PCIe 4.0, which isn't a given on X470

[cinder lagoon]

Afaik it isn't given at all on x470 - 4.0 is nice to have but I wouldn't really pay extra

[mossy gull]

It will on newer GPUs

[jade scaffold]

Yea but you can't use them

Not for anything that needs more than x4 performance because the ryzen cpus don't have enough pcie lanes

[mossy gull]

I always rock a hybrid GPU rig, so the extra displays don't consume resources from the main GPU.
I also like tons of storage

[jade scaffold]

yea but a Ryzen CPU doesnt have enough PCIE Lanes

so you have to play the good ol sacrifice game

use PCIE slot 2 loose sata 5 and 6

use M.2 3 loose PCIE slot 3

thats how both B550 and X570 boards work

X570 just has the advantage of everything near enough being Gen 4 not a bit of Gen 4 and the rest Gen 3

[mossy gull]

i don't use SATA

[jade scaffold]

regardless X570 doesnt have more PCIE slots

it just has higher bandwidth ones

and is willing to bottleneck things more

[mossy gull]

I rather have PCIe 4.0 over 3.0

[jade scaffold]

thats cool and all

but that means if you have 2 PCIE Gen 4 M.2 drives

they can never run at the sime time and get full speed

honestly you have a server just throw some Intel or Kioxia drives in throw them in a Raid array and get some 100gb networking going will be faster than and M.2 Gen 4 or 5 drive that currently exsists

[sonic meadow]

It has 6 more pcie lanes than b550

[jade scaffold]

physically yea

[sonic meadow]

Whether or not you get more slots is entirely dependent on the motherboard

[jade scaffold]

but a ryzen CPU doesnt have more PCIE Lanes to support it

and the chipsets PCIE lanes arent beefed up

so you still end up effectivly with a shared x4 lane to the CPU for most of the available slots

[sonic meadow]

And most devices aren't continuous throughput so that is usually fine

[jade scaffold]

yea thats fine if you are willing to sacrifice the odd pair of sata ports and 1 of the pcie slots for the M.2 slot

most people dont fill out PCIE slots anyway

[sonic meadow]

However you have said multiple time that x570 doesn't have more lanes/whatever than b550, which is false

[jade scaffold]

i said slots

which they really dont past having the extra M.2 if you wanna count that

you have the rare super varients of the boards which cost more than some midrange gpus

which have some electrically 16X slots linked up to the chipset because funny i guess

anything that needs a 16x slot is probably gonna kick the chipset in the balls asking for more throughput

[sonic meadow]

a quick perusal of around 80 boards (44 b550, 38 x570) shows that x570 boards have on average both more pcie slots and more bigger slots. though the data I use is just the physical slot not the electrical, nor does it show m.2 slots

(ignore the first few headers, that was from the source data which wasnt formatted well)

(that last column is total slots)

so yes, x570 boards do tend to have more slots

[jade scaffold]

is that only including ATX boards

[cerulean helm]

So, after several days of trying to find a solution to my new LG monitors flickering I may have found the culprit. There is a Nvidia driver hotfix for exactly my problem:

"When using multiple monitors which support adaptive sync, users may see random flicker on certain displays when G-SYNC is enabled after updating to driver 535.98"

https://www.nvidia.com/en-us/geforce/forums/game-ready-drivers/13/520195/announcing-geforce-hotfix-driver-53609-released-61/

[sonic meadow]

It was all boards (on local pricespy, since I knew I could get info out of it), minus a few that had null information. I probably should have gone through and culled all that stated 0 slots too since they would be bad data.

[cerulean helm]

Can confirm the hotfix driver has fixed the problem, no flickering at all for 30 min now at max refresh rate.

[sonic meadow]

nice!

[jade scaffold]

Seeing some info arround that the mi300 has over 14k cores

That would be over 2x the 7900xtx which just doesn't make sense

[sonic meadow]

I mean it has 3x the transistors

153 billion vs 57 billion

[mossy gull]

Why not?
It's a bigger die

[jade scaffold]

Yea but that's ALOT

In theory that's beyond 4090 levels of power

[mossy gull]

An unlocked 7900XTX is already faster than the 4090

So if you have an unlocked MI300, then NVidia can't beat you at all

[jade scaffold]

It's really not tho

I should rephrase that in specific picked benchmarks it can be

Which mainly comes down to amds better support for vulcan and opengl

I guess the reason why the mi 300 has such insane specs is because of its chiplet design really it's like 3 gpus glued to each other and then with a cpu. Imagine if Nvidia would pull their head out their ass imagine the kinda chiplet gpus they could make

[sonic meadow]

not sure I want to see their power consumption for that

[jade scaffold]

Betting it'll be arround 550w

The gpu and cpu cores will likely be slower for stability sakes

Than consumer varients

[mossy gull]

An unlocked 7900XTX does almost 700w.

[jade scaffold]

Yea having full power and voltage control let's you do crazy stuff

[sonic meadow]

an unlocked and hyper-cooled 7900xtx does almost 700w

[jade scaffold]

But it also let's you do reverse crazy stuff

If you can tune your voltages really well you can maintain like 98% of your performance and drop like 15-20% of your power consumption

Which I think is a much better use of unlimited processor controls

Additional note on the mi300 no vulkan openGL or DirectX support ;-;

I get why

I'm still not happy about it

[mossy gull]

But it was a custom water cooling, not liquid nitrogen

[sonic meadow]

it was chilled water

[jade scaffold]

Which almost may as well be liquid nitrogen

[mossy gull]

But for Liquid Nitrogen you need a complete set-up and you only can run it temporarily.
With chilled water you can use off the shelve components.

[sonic meadow]

chilled water (like ln2) is a setup basically only used by overclockers

and can get you notable gains over air-cooled coolant

[mossy gull]

But you can get chilled water with off the shelve components, while you can't with liquid nitrogen

[sonic meadow]

and?

[mossy gull]

It's still a difference if one does something with off the shelve components or liquid nitrogen

[sonic meadow]

ln2 can also be done with off the shelf components, you can buy the ln2 pot/heatsink

[mossy gull]

In a lot of countries you actually can't, I can't buy it in the entire Benelux without having a license.

[amber fable]

Both need about the same amount of board prep.

[sonic meadow]

you cant buy a small nickel plated copper box without a license?

[mossy gull]

We can't buy LN2 without a license.

[amber fable]

Also, WTF kind of license would you need for LN2?!?

[sonic meadow]

the original point however was that chilled water is not a common or everyday setup, and as milo pointed out needs very similar board/system prep to LN2 anyway

[mossy gull]

We can easily buy water chillers😃

I think it has to do with safety of the product, and the government has to approve it here if it's safe enough for consumers

[amber fable]

"safety" Sure. Ok.

[sonic meadow]

people dont use water chillers, they stick a radiator in a bucket full of ice water/brine

[mossy gull]

I mean, for longest of times electric sliding doors on cars were illegal because it could hurt the user.

But yeah, we need a license for tons and tons of stuff.

[mossy gull]

Oddly enough we can buy chillers here, like you know, thos big units that pull more juice than a breaker can provide.

Easiest way to get liquid nitrogen are fire extinguishers.

Even CO2 is easier to get

[mossy gull]

So I did something nuts, and I think I'll watercool my laptop next and rebuild the bottom chassis.
But I took an old GPU cooler, put it on my laptop's vapour chamber, and funny enough it dropped 15°c.

So if this works, I think I may be able to sell laptop mods that only require replacing the bottom panel

[cinder lagoon]

"sell" is a little ambiguous..
If the vapor chamber is painted, the heat transfer will be shit and you don't know how the paint would interact with any thermal shmoo.
Do the Vapor chambers have any mounting hardware? - No, probably not.
Do Vapor chambers support mounting a cooler by screwing in somewhere else? No. They will probably collapse.
"replacing" the bottom panel is first of all: not always possible,
2. Not always of the same material,
3. Always not of the same form
4. Really stupid because:

• what are ye gonna do?? Let two metal spikes with tubes run out the bottom?
• Have a block stick out and prevent users from putting it into backpacks or pouches?
• never have it on a table again?

So all in all: yes you did something nuts 😂

[mossy gull]

Actually if you take a 1U water cooling block you can keep the system somewhat flat as the tube exit are on the side of the block.
Like 2cm thicker.

I tested the temps by using an old GPU cooler(MSI R9 270X), and it dropped by 15°c, went from 95°c to 80°c by just putting it on the vapor chamber.

So if I can make a custom bottom chassis with the 1U CPU block which has a much bigger surface area with tubes leading to the back(with quick disconnects) you can attach an external water cooler.

With the test I done all the cooler did was laying on top with some support and thermal paste

And it still will fit in laptop bags, I once took 2 laptops in 1 compartment with me, aka an SB2 and the ROG G15 AE

And the vapour chamber can have some tension as the bottom panel directly leans on it.

[mossy gull]

Ubiquiti, what?

[cinder lagoon]

What?? Tf is an "Apple of Eden"? 😂

[tender plank]

I'd guess that's the name of their AP.

Giving forbidden knowledge, seems accurate for the internet 😄

[mossy gull]

My modem is called Yggdrasil

But the update is a downgrade

[hasty rose]

Err, I accidentally ran an old bat file that I found on my pc...
I forgot what it did...
Seems like it's deleting a lot of temp files?

This won't cause me issues at any point right?

[sacred seal]

Well history and cookies could be fun, but other then that probably not

[hasty rose]

So that is all it did... I wonder why i made this bat...

[inland dove]

Definitely not going to download that

[hasty rose]

Well its a text file, so it wont do anything, but yeah don't download stuff you don't understand or trust

I was more wondering if someone could tell me what it did, other than the obvious del (delete)

[cinder lagoon]

Seemingly something that this window now does - looks really old. As in "pretty sure there are no history or cookies folders in C:\Windows anymore" old. Something from an era where multi-user systems were still new

And we've already got a replacement for that one aswell xD

[hasty rose]

Strange, the file was "Created" September 2020...

[mossy gull]

@hasty rose look in Windows Settings for Storage Sense.
It cleans junk automatically and in a safe way.

[jade scaffold]

Quest 2 and Quest Pro performance boost now out Update V55
26% CPU Clock increase for both devices with a 19% clock increase for the quest 2s GPU and 11% for the Quest Pros GPU
Pretty dam good from just an update

[lusty heart]

Just did a fresh install of Windows 10 and a BIOS update. Trying to squeeze a little more performance out of my 7800X3D. Running a -30 offset and P95 pretty stable so far. 1hr in.

[mossy gull]

Why are you trying to overclock an X3D CPU?

[lusty heart]

Not overclocking.

Undervolting

[sonic meadow]

Undervolting means less current, which means less heat, which on AMD usually means it boosts better at the same settings. The stock voltage is pretty conservative, set to work reliably on even bad chips

[jade scaffold]

Also undervolting is a must on 7000 imo

The ihs is just too thicc not to

Also coolers aren't designed ideally to deal with them it's why the offset bracket exists

Also have decided I'm going to be picking up a low end skew of their next gen threadripper for the pcie lanes mainly

[sonic meadow]

tasty tasty pcie lanes. the extra ram channels can be nice too

[mossy gull]

That's my original plan as well

[mossy gull]

Fair enough, personally I am going direct die cooling

[jade scaffold]

Hoping they do a 12 core

[lusty heart]

Well so far -30 failed testing. Crashed several times. I dropped it to -20 and so far so good. Did an overnight test on Prime95 and it ran smoothly. Could maybe fine tune it but this is stable for now so I'm gonna stick with it. Question is, should I leave it to Ryzen Master to do the offset or should I use the BIOS setting?

[cinder lagoon]

Probably bios. Just in case your undervolt becomes unstable some day, you'd wanna be able to revert manually. RM has some built-in safety disable feature I think but I wouldn't bet on it!

[lusty heart]

I think it does. It reverted my offset to "off" when it crashed last time.

[cinder lagoon]

Ahh good

[sacred seal]

Don't you love it when programs blame their problems on others.

Oculus app: We have detected an issue with your GPU drivers, try reinstalling them
Reinstalls the oculus app instead
Fixes the problem

[cinder lagoon]

Well, programmatic error recognition is really hard, otherwise we would not have to reinstall windows constantly or have crashing programs.

Wrong error recognition on the other hand is really easy 0:)

Surprised the satement doesn't include "reinstall the app, if you haven't done so yet"

[mossy gull]

I love when your GPU drivers tell you that YOU removed the GPU

[sacred seal]

What I find amusing is it is so assertive that the issue is with your driver. Its not "we encountered an error and we think its with your GPU drivers", its "Your GPU drivers have an error, reinstall them now"

[mossy gull]

YOU know it's always YOU that is the problem with YOUR pc because YOU created the problem so YOU need to fix it.

[cinder lagoon]

YOU know it's always YOU, that is the problem with YOUR pc. because YOU created the problem so YOU need to fix it.

[deep island]

Hey fellas, I have a very specific question for anyone who works with carbon fiber. When carbon fiber fails under compression, does it tend to crack, shatter, or flex?

[mossy gull]

It shatters

[jade scaffold]

It depends on treatment actually

There's ones that are made with a resin like substance they shatter

There's some ones that are a bit more fabric like that tear

[mossy gull]

True carbon fiber, like ones used on cars, is usually made in a single shape, and when bend it shatters

[jade scaffold]

Very few deform into a bend

Though you can make super flexible carbon fibre like on planes which can carry crazy weight as well as bend under stress to avoid damage as well as help with aircraft performance sometimes

[mossy gull]

It still doesn't bend like what you can do with plastics

[jade scaffold]

See if you can find out what the intel 7th gen dell XPS laptops had their keyboard area made out of

Best feeling laptop I have ever felt

[mossy gull]

There were a few that were made out of carbon fibre, but also a few made out of plastic that looked like carbon fibre.

[jade scaffold]

The 7th gen xps laptops were carbon fibre you cannot make plastic that Immensely solid and light

If you use good quality carbon fibre the chance of anything breaking it is slim

[mossy gull]

They weren't that solid, the deck really flexed.

[jade scaffold]

No they really didn't I was renounting the cooler on my mums one and that thing had next to 0 flex probay because it's other than cf solid aluminium

[mossy gull]

I like it on cars, even though many people don't like it.

[jade scaffold]

Also fantastic keyboard

[mossy gull]

Dell makes fantastic laptop keyboards, I just hate they overheat so easily.

They don't overheat they do need regular cleaning tho

The vents get clogged up very quickly

[deep island]

Thank you. I wanted to verify some stuff that's being reported about the loss of the Titan this week

[mossy gull]

Ones I used thermal throttled so much they were near overheating, even after a good clean.

[mossy gull]

Are you gonna break some Carbon Fibre?

[deep island]

No, I just wanted to do a sanity check on the materials science being thrown around online

I know a fair bit about implosions and how submarines sink already, but the failure modes of carbon fiber is decidedly not something I know much about in that context.

If it shatters, then that means that it goes slightly faster than a metal hull would, and any debris field will be larger than normal

[mossy gull]

Steel is heavy and strong, and not too expensive so that's why they use it.

I am a scuba diver with a carbon fibre air tank, the advantage is my scuba tank is smaller and can carry more pressure, but I need to carry more weight with me compared to my buddies with a bigger steel tank.

[surreal moss]

@peak shale Do you use carbon fiber at your work?

[peak shale]

Quite a lot, but not in the same mechanical form.
It's not a magic miracle material.

I do have a fair bit of experience with fuckin up carbon fiber as similar to the sub though and while it's amazingly stiff it will snap when it does break.

All of my arrows and a fair bit of motorcycle helmets and parts I've managed to break are carbon fiber. The issue is we have no idea what type of resin system they used, but at the end of the day it likely prioritized stiffness over flexibility and when it did, it would likely sheared off the surface of any titanium it's bonded to and broken into pieces

Whether is plastic reinforced by the stuff or fiber sheets it's stiff and breaks

I wouldn't say it shatters necessarily as that's a very specific failure mode that implies the whole thing fails when a small section fails, like tempered glass does, but it does fracture in the immediate region of the failure, and when it does that region effectively loses all of its strength at once.

[mossy gull]

Shatter is a litteral translation from my language, it's the same if it comes down to glass shatter or fibre shatter, wood also can shatter in my language.

With the word fracture it's more like it breaks apart, which we use for bones.

[amber fable]

I would absolutely buy more memory if something like this was made into a modern BIOS feature.

https://www.youtube.com/watch?v=q5M0TwnkWUM

This is such an amazing idea, and I want it to work on my computer.

[deep island]

You might find this useful. He goes over the pressure hull construction from 3:45, and has video of the endcaps being adhered to the carbon fiber.

https://youtu.be/4dka29FSZac?t=225

[peak shale]

Understandable.

[ionic tusk]

Any sff recommendations that fit nhd15?

[mossy gull]

Why are you trying to put a humongous cooler in an ITX case?

The biggest ITX cases I know are the Fractal Design Nano, Razer Tomahawk Mini and Thermaltake The Tower 100 Mini.
But even those can't fit humongous coolers.

[sonic meadow]

I'm sure they can if you take the side panel off :p

[mossy gull]

Then why not just get a test bench

[ionic tusk]

@mossy gull just trying to find a case so I can off load my nh d15 to my brother

He only likes sff I-I

[mossy gull]

The NH-D15 already has height clearance on full size cases, I doubt it'll fit any ITX case

[sonic meadow]

Some miniitx cases are basically just short mini/atx cases

It supposedly fits an the Nzxt h200i (cooler height of 165mm, in a case with cooler height support of 165mm)

[mossy gull]

Sooo, depending on the CPU it will or won't fit

[sonic meadow]

I'm not sure how much variance there is between different sockets

No more than a few mm regardless

[mossy gull]

Few millimeters, for example an PGA is few mm taller than LGA

[sonic meadow]

I think that pairing would be a case where you should check if other people have done it, and with which socket/cpu

The cooler master nr200p however only had CPU cooler support up to 155mm, so wouldn't fit.

Fun fact: every object can explode if you compress it too much.

[tender plank]

Yep

[barren juniper]

https://www.notebookcheck.net/Intel-Core-i7-8809G-SoC.275832.0.html apparently this was a thing at one point in time. Intel cpu with vega graphics and HBM2

https://www.notebookcheck.net/Rivals-with-benefits-Intel-and-AMD-collaborate-to-create-a-new-entrant-to-the-8th-generation-CPU-family.262554.0.html ahh

ahh it was for nucs

[cinder lagoon]

???

Lol

So weird

[balmy flicker]

so file explorer crashed and windows decided to kill the application

[sacred seal]

That's always a fun bug

[cinder lagoon]

Press win+R

Enter explorer.exe

[balmy flicker]

not working at all

[cinder lagoon]

If there's still some process lingering enter taskkill /IM explorer.exe /Fbefore

[balmy flicker]

I am not getting the Run menu

[cinder lagoon]

Ohh tried opening task manager via ctrl+alt+delete

It has a run dialog in the top left

[balmy flicker]

no luck

I can fix it by loging out I have done this befor

but this is the first time it was because of a crash instead of me killing the program from task manager

[cinder lagoon]

If its fixed by relogging, my method should work

[balmy flicker]

it would but I am not geting task manager

[sacred seal]

I would try dism, I used to have a problem where explorer would crash every time I went into the "open with" tab when right clicking on things

[cinder lagoon]

Incase of any confusion:
open a run dialog (win+R, taskmanager top left run)
enter taskkill /IM explorer.exe /Fand press enter
open a run dialog again
enter explorer.exe

[cinder lagoon]

Tried ctrl + shift + esc yet?

[balmy flicker]

ctrl shift esc does not work either

[sacred seal]

Should be able to run explorer.exe in command prompt as well

Though opening it without exlporer could be interesting

winkey+x might do it

[balmy flicker]

no luck

[sacred seal]

Also opening a folder from your desktop might cause the thing to restart

[balmy flicker]

explorer is still crashing can't use win key

[cinder lagoon]

Is the desktop still white-ish?

[balmy flicker]

yepo

[cinder lagoon]

If you spam click a non-responding "window" you will get the option to force quit it

[balmy flicker]

all windows work fine though

the desk top is what crashed

[cinder lagoon]

Yes the desktop is a window behind the scenes

[balmy flicker]

I am aware but end process does nothing

[cinder lagoon]

I mean quitting the "troubleshooting" popup, this should do it

[balmy flicker]

the x and end do nothign same for cancel

[cinder lagoon]

Hmm

[mossy gull]

Sounds like Windows needs a reinstall

[cinder lagoon]

Ahh hell nah, try the dism stuff first

[mossy gull]

Dism never worked on my side

[cinder lagoon]

for ($i = 0; $i -lt 5; $i++) {
    Write-Host "${$i+1} of 5"
    dism /online /cleanup-image /restorehealth
    sfc /scannow
}

powershell loop to help windows actually fix things

I always gotta run it a bunch of times before it actually does anything

[balmy flicker]

so how do I run stuff when my start key does not do anything and I can't even open task manager

[sacred seal]

Well you will have to relog/ restart first

[balmy flicker]

then what is the power shell for?

[cinder lagoon]

Windows error checking after restart

[sacred seal]

To hopefully prevent something like this from happening in the futrure

[mossy gull]

More advanced version of Command Promp

[balmy flicker]

so now that I have restarted how would I run that?

[sacred seal]

You just open up shell and copy and paste the command

[balmy flicker]

k

[cinder lagoon]

...so did it work?
you used powershell, right?

[balmy flicker]

have not used it yet

also has any one knoticed that brave is having a skill now working corectly atm

I have internet and can load youtube on chrome but it will not load on brave

corection chrom will not load new tabs either

[cinder lagoon]

Yeah, dism needs admin rights...

[cinder lagoon]

At this point I recommend a full reinstall

Start powershell as admin and run it again

[barren juniper]

damn power color xtx for 830

also there was that microcenter deal for the xt at like 700 or something like that

[balmy flicker]

restarted and got the brosers working again I think them crashing is unrelated to power shell

[balmy flicker]

ran, came up clean looking

[cinder lagoon]

[manic vale]

Hi there, I am looking for a Klinke 3,5 Switch (pc to 1 Headset or 2 Speakers) u have some idears?

[sacred seal]

Could you be more specific as to what you are looking for? You just want a device with one audio in and two audio out that you can toggle between?

[mossy gull]

Usually audio interfaces can do that.
If you want to use both at the same time then you need a splitter.

Also Windows can switch between outputs if you have multiple outputs

[manic vale]

Well I want to avoid to switch output via software

so im using this so far

But it seems, the mechanic inside is goin down slowly. I have contact issues and sometimes one side of my Headset goes mute. With USB both sides work ^^ My guess is that the mechanics inside there weathering down by now

Now I look for a replace

[mossy gull]

You know that speaker and headphones have a different soundstage and dynamic range?
That's why companies usually opt for software switches.

[sacred seal]

Assuming you have enough ports on your desktop, I would just use ear trumpet (which is a piece of software)

If you want hardware, basically anything will work. There is not a lot of sofisitication in a device like that

Its basically two lightswitches glued together

[mossy gull]

https://www.amazon.com/Switcher-Splitter-One-Key-External-Required/dp/B08F392WVP/ref=mp_s_a_1_18?crid=2F73Q76BO4MN&keywords=Audio+switch&qid=1687990357&sprefix=audio+switch%2Caps%2C219&sr=8-18

That's all I can find that doesbreak the bank, and works in both way apparently, but personally I don't have any experience with these devices as I use an audio interface and a software toggle. @manic vale

[manic vale]

https://www.amazon.de/LiNKFOR-Umschalter-Stummschalttaste-Stromversorgung-erforderlich/dp/B08L3BQCF7/ref=asc_df_B08L3BQCF7/?tag=googshopde-21&linkCode=df0&hvadid=546439027635&hvpos=&hvnetw=g&hvrand=18189856276863302488&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9043597&hvtargid=pla-1096737201575&psc=1&th=1&psc=1

found a similar one

[sacred seal]

Under the hood they are all the same

[manic vale]

Well I like this kind of device for practical access ^^

[manic vale]

Well I think so too by now

[sacred seal]

Untimiatly the exact one you choose is not going to matter much, as long as its reasonably well reviewed

[manic vale]

well amazon revieves arent most trusted by me but a lot positive feedback has to say something at last ^^

[sacred seal]

No, your right that amazon reviews are not great, but typically if it is well reviewed you can be reasonably sure its not going to fall apart right away

[manic vale]

The eartrumpet software will be on test also i think ^^

[mossy gull]

My Avermedia AX310 has a touch display, on there I have a software toggle to switch between my soundbar and headphones.
Primarily because my soundbar is Dolby Atmos and my headphones aren't.

[mossy gull]

Read what the reviews say, sometimes bad reviews are just dumb things like people expecting stuff like having all cables in the box.

[manic vale]

I also look the hardware up in reseller stores, when they listed there its also a good thing. here in germany is conrad an example

[mossy gull]

@manic vale
This may interest you, it's a lot more expensive but the headphone stand from NZXT has a switch on it so it automatically switches your audio when you put your headphones on the stand.
https://nzxt.com/product/switchmix
https://youtu.be/aAqWv24tM5k

[manic vale]

Nice one, but to expensive for what I need ^^

[sacred seal]

I would also never trust LTT with sponsored content

[mossy gull]

I mean, people trust it faster than a random's word these days.

[surreal moss]

You could also look into a two channel mixer. Would take a bit to adapt things though

They start around $30 iirc

[cinder lagoon]

Well, sponsored content is explicitly not a review, just an unboxing and opinion at best

[cinder lagoon]

Why is that specifically?
If you had bluetooth headphones set as default output device in windows and turned them off, it would automatically fall back to the last default device besides the bluetooth headphones (the speakers, for example)
There would be a miniscule delay between that but it works fairly relaibly and also for 3.5mm jack audio equipment (although, the motherboard must support sensing if there is a device attached)

[cinder lagoon]

... wait... if you have a good mic plugged into that why would you want to switch to a wired headset one? 🤔

[mossy gull]

Or they have an old fashioned headset or mic.

This is why software solutions are much better, you have way more control.

[surreal moss]

Gonna disagree there. More flexibility maybe in some ways. Definitely not more control in all aspects

[manic vale]

Its to switch between speakers and headset/mike. I just want to push a button to switch between them on the fly. Even in game etc instead of tapping out or clicking software. Well I dont know if there is software, where I can use a keybind to do the trick also. I had no other fancy thoughts with it ^^

[sonic meadow]

not all games like switching audio devices on the fly

[manic vale]

Had no trouble with this aspect so far.

[west mirage]

hey

Need a new college lap top

My college gets discounts on lenovo, dell, and Mac's

I want something with very neg gen hardware, like 7000 Series AMD GPU's, and Ryzen 7000's

[cinder lagoon]

Tbf, your solution was handled in hardware - the games were just simply not aware of it.
If that is the case, there are programs to set key combinations as hotkeys to toggle the audio device but given that games do not like it, I would actually recommend sticking to the hardware solution

[mossy gull]

What's your budget

[west mirage]

ain't got one

@mossy gull

Something I can also game on would be nice for Star Citizen lmao

[cinder lagoon]

I think there are no laptops (yet?) with modern dedicated AMD GPUs..
Ryzen 5000 + NVidea dGPUs should exist tho

Yea, found some r5000 Strix laptops and an IdeaPad with r6000 + 3050Ti

[mossy gull]

Closest I can think of is the Corsair Voyager

[mossy gull]

https://www.corsair.com/us/en/c/gaming-computers/laptops

[mossy gull]

AMD hadn't released any of them.

[cinder lagoon]

Yea there are no r7000 laptop CPUs yet

[west mirage]

Also forgot to mention

I get educational discounts for lenovo and dell @cinder lagoon @mossy gull

Ryzen 5000 + the newest nvidia gpus would be nice tho

[cinder lagoon]

Said that - tho I'm pretty positive that they don't have ryzen 5000 yet

[west mirage]

32gb ram is required

[mossy gull]

Then there's no full AMD systems, only Asus and Corsair make them.
You do have the laptops with AMD CPU and NVidia GPU.

[cinder lagoon]

Why do you want an AMD GPU specifically?

[mossy gull]

@west mirage look for the Lenovo Legion Pro 5 or Slim 5.
Those are the only Lenovo laptops that can game that have an AMD CPU.

If you go to Dell the only thing you can get are Alienware M15, M16, M17, M18.

[west mirage]

Alienware 🤮

[mossy gull]

Dell gaming series is way worse

[cinder lagoon]

Dell in general is sucky, with all their upsells and extended warranty bs

[mossy gull]

Funny enough, here they're actually pretty good
Here Acer is the 1 to avoid

[cinder lagoon]

Gotta say where "here" is tho

[mossy gull]

Netherlands

[manic vale]

Found a switch for my issue, was about to order then read. For 3 Pin only, checking headset 4 pin cause mic < - <

[cinder lagoon]

Well you can always split a 4-contact jack into mic and audio

[manic vale]

Mean with y cable?

But will the 4 pin will be pulled through the switch and go through the y cable that connects the switch to the PC then?

[surreal moss]

I would have to draw that out to understand it

[manic vale]

Headset/Mic > 4 Pin Cable > Switch (can only handle 3 PIN in/out slot?) > Cable to PC end in Y cable for Sound and Mic port.

The other out switch port is for my normal speakers, there would be no issue

[sonic meadow]

bah. ups batteries died on me... 😦

only three years old too, which is the minimum of the age ranges I am seeing online for batteries in a UPS application

[mossy gull]

If they have a lead acid battery(car battery) inside then 3 to 4 years is normal.
If they have a Lithium battery they last a lot longer but are way more expensive.

[sonic meadow]

One source I squinted at said 3-5 years, with a few others suggesting a bit longer. Just a bit irksome as I'm not working so would rather not have to spend the money on replacements

Of course it doesn't help that it's winter at the moment

[mossy gull]

Sadly this is the nature of lead acid batteries

[sonic meadow]

Yup

[cinder lagoon]

What kind of UPS is it?
LiFePo4 batteries (as in most UPS) hold literal ages and are very hard to mistreat!

[sonic meadow]

~7Ah lead acid bricks. for a probably 20 year old APC ups

[cinder lagoon]

Ahhh hmm okay seems possible at least xD

[sonic meadow]

I got it... 15 years ago and it had just been sitting on a shelf

[cinder lagoon]

But the lead-acid cells are the same 20 year old things and it's just been "active" for 3 years?

And active as in "daily backup power" or active as in "been pretty much just idle"

[sonic meadow]

nope, these ones i bought 3 years ago. I had shelved the unit years earlier after the batteries I got with it started failing on me

as far as I am aware the power at the site is reliable. but my servers havent been going down so I dont actually know 😆

[balmy flicker]

I need a web cam for an interview and need recommendations
I was thinking a c270 from Logitech

[sacred seal]

Personally I would just get a cheapo 1080p afair off of amazon

They tend to have a bit more fisheye, but the image quality is a decent degree better then the 720

270*

[barren juniper]

hmm so apparently star citizen gets massive gains from x3d chips. good to know

my next build will have one

if i didnt already have a pretty decent laptop id probably consider the 5600x3d am4 ram bundles

[cinder lagoon]

...is it just me or is this windows download page empty in only firefox? 🤔
https://www.microsoft.com/software-download/windows11

[mossy gull]

Just on your side I think

[jade scaffold]

Yea that's not atall surprising anything to do with memory you can make better will run the mess that is star citizen better
So more cache more RAM faster RAM will all help star citizen enormously

[pearl moon]

Important to note that the 5800x3d is only $100 more

But frankly if you're doing a whole new mobo build anyways, am5 might be the way to go if you can find a good deal.

[cinder lagoon]

yes but 100 bucks less for great gaming performance (if you don't need the multicore stuff) is a great deal.
Also: kinda sad, its not global...

[barren juniper]

though id probably just get the cpu, as since the store i go to is on manhattan and you have to take the subway, id rather not have a bunch of large boxes with me

but if its just a cpu i can put that in my pocket

[cerulean helm]

Oi, so my pc randomly shut off while watching a video. No BSOD,, no reboot, just straight powered off.

Rebooted and went to check the event viewer to see if I could find anything and holy crap I had an error message spamming every second:

A corrected hardware error has occurred.

Component: PCI Express Root Port
Error Source: Advanced Error Reporting (PCI Express)

Did a quick search and found several posts on ASUS forums (I run a Z790 Asus board) about checking the PCIE power management setting in bios and disabling it if it its enabled.

Went and checked and yep it was enabled. Turned it off and I haven't had the error in the 20 min the pc has been on.

[sonic meadow]

Damnit HP/Dell. Stop shrinking your damn PSU plugs by fractions of a mm...
Tested my project laptop (dell) with a charger from a modern hp laptop. Assumed it was blue tip (since I'm pretty sure it visually was) which is 4.5mm. and after buying a 4.5mm from dell it doesn't fit, the hole is 4mm.
That's what I get for not checking the damn hole/plug with calipers first

Was hoping to get the thing charging so I could install and test the replacement screen.

Well it would help if dell actually sold something small enough to fit their own laptop... (Locally that is)

Oh wait. Ignore me. I was trying to plug it in to the headphone jack

🤦

[mossy gull]

Have you checked your systems temps?

[cinder lagoon]

try updating your chipset drivers.

[cinder lagoon]

if you frequently have to do with laptops without USB-C charging, I strongly recommend getting one of these barrel plug laptop kits and a variable power supply
It seems like for some reason, many laptop manufacturers literally just changed them just so its different

[sonic meadow]

nah, I had just fucked up when trying to plug it in.
this is going to hopefully be my new "daily" runner laptop (not that I use my laptop that often). so I wanted as un-jank for the charging as possible. I had originally planned on using an old chunky hp charger with a blue tip adaptor. but I cant find the adaptor I purchased ages ago

I am a bit irritated it doesnt have usb-c on the laptop though. its a ryzen-something so its new enough I would have expected it. but it just wasnt something I was paying attention to, it was a cheap laptop with a busted screen

[jade scaffold]

found a carrier board I actually like and am gonna get

Has a lil hdmi ribbon cable connector and is only 16mm thick soooo with me soon to own a 3d printer it might be time to try my hand at making a bootleg steam deck

Wonder when thoes piezoelectric electric fans are gonna become available for normies would be awesome to have for a hand held

[cinder lagoon]

Fo sho

[jade scaffold]

Hoping this carrier doesn't die on me

[mossy gull]

If they ever become available, so far everything that's been an amazing PC invention so far has been cancelled because nobody liked them

[jade scaffold]

Nah these have real advantages

Quieter more efficient In cooling and power consumption

I very much would expect them to show as a real thing considering when we saw them last they were gearing up for production

they are also turbo reliable

like lowkey can last for 5 years and beyond with only the filter needing to be replaced and the filter is just a cheap paper filter

also they are backed by intel and Qualcomm so they got some really big names behind them

[cerulean helm]

Temps were fine, both the cpu and gpu are watercooled. And other than a newer Bios, my all my drivers are up to date.

[mossy gull]

I love German logic

[mossy gull]

Even Chipset drivers?

[cinder lagoon]

Because the dvice ID is specifically an Intel PCI Express root port - maybe check for more up-to-date drivers on the intel side

[cinder lagoon]

...yeah, great Microsoft. I wanted two Anti Virus interfaces...

[cerulean helm]

Yup, up to date from the Asus support page. Nothing listed to update on Armory Crate either, nor using Intel Driver and Support Assistant.

[cerulean helm]

Its been 2 days since I turned off Asus PCIE Power Management in the Bios and have not seen that error message return since.

And using Intel Driver and Support Assistant shows nothing needs to be updated.

[inland dove]

Would this work if I'm using a CPU with integrated graphics?

[mossy gull]

Depends, what CPU are you using?

[inland dove]

Intel Core i3-1005G1, in my laptop.

I did set the priority to above normal and it did improve my game's performance by a bit.

But didn't want to go beyond that.

I'm running off integrated graphics.

[mossy gull]

Keep in mind, some older games don't understand when you use an Intel iGPU because it lacks VRAM.
And if the game runs I doubt that high priority will make a huge difference because that's just for the CPU, not GPU.

[inland dove]

So I didn't know if that would break anything if I limited it's cores.

[inland dove]

No dedicated GPU.

Would limiting it to only one core help or potentially break anything?

[mossy gull]

It won't

[mossy gull]

Depends on the game, all Windows does is moving the game's processes to 1 core.

[inland dove]

EAW is an old game and from what I've been told it can only utilize one core.

Is there a way I can tell what cores are doing what?

This probably wouldn't help my performance.

With this CPU.

[mossy gull]

There is, but it'll probably break your mind more than it answers stuff as all your programs jump between the cores unless you aks them specifically to stay on 1.

[inland dove]

I have 2 cores and 4 logical processors? and 4 options?

[mossy gull]

2 cores, 4 threads

0 and 2 are 2 cores, 1 and 3 are hyper threads

[inland dove]

What does that mean?

[surreal moss]

It's a fancy trick to get double the amount of work out of each core

[mossy gull]

Eh kinda hard to explain, but hyper threads are slower than the actual core.

[surreal moss]

Basically it's a way to have a physical core give you two virtual ones

[inland dove]

So If I wanted better performance I would have the game only using 0 or 2?

[surreal moss]

You don't normally have to understand much beyond having 4 cores to work with

well... 0 wouldn't work to well for you

oh, if the game isn't written to handle more than one core then you're limited to your cpu speed

[mossy gull]

I usually explain an hyper thread as a rush-hour lane on a highway, but we probably only have those in the Netherlands 😃

[inland dove]

The game can only do single core to my knowledge.

[surreal moss]

SPOILER: ||Netherlands isn't the only place with those||

[surreal moss]

Then unfortunately more cores won't help you there

[mossy gull]

Wait, other countries have them too?
I literally never seen them outside the Netherlands 🤣

[inland dove]

I'm going to try and set it to using core 2 only.

That way maybe I can squeeze a bit more performance out.

Setting the priority to above normal actually did make the game run a little smoother and I haven't noticed any detrimental side effects to doing that yet.

[surreal moss]

Just read through. You're trying to improve performance of EAW on a laptop?

[inland dove]

Yeah.

I am.

[surreal moss]

and your base speed is 1.2 GHz? That is technically slower than the min spec requirements for EaW

so increasing the priority makes sense that you would see improvement

but I'm not sure you'll be able to get it "perfect"

[inland dove]

The game runs fine in battles, but I've been testing for the new Big GC map for AOTR and it's really been a tough time with the poor performance on the GC map.

[surreal moss]

Yeah that likely isn't going to get better from what I'm reading

[mossy gull]

1.2GHz now is miles faster than the probably 3GHz from back then though.

[surreal moss]

Changing cores won't make any difference

[inland dove]

From what I read it's more a fix for higher end systems or CPU's with more cores but I think it's worth trying.

[surreal moss]

Sure, give it a shot.

wait hang on

[mossy gull]

Sims 4 requires a 3.2 GHz 2-core Intel 3rd gen CPU, but my SB2 1.9 GHz 4-core 8th gen, while speed is under spec, blows the Intel 3rd gen out of the water.

[surreal moss]

How much memory do you have?

[surreal moss]

That's probably multithreading working in your favor

[inland dove]

I have 12gb at 2667MHz

[surreal moss]

12gb is an odd number but, okay

You might be right about limiting the cores though

[mossy gull]

Or IPC improvements of the CPU

[inland dove]

Laptop came with 4 soldered and an empty slot.

I put 8 in.

[surreal moss]

Nice

[inland dove]

RAM was bottlenecking me before I upgraded but now it's my CPU that's bottlenecking my whole system.

A lot of games will push my CPU utilization to 100% or close to 100%.

[mossy gull]

The i3-3220 Sims 4 requires has a single core score of ±1700, the SB2 i7-8650u has a single core of ±2100.
Even though on paper the i3 is almost 1.5 times faster, it's actually slower thanks to generational leap.
So Cheesy's CPU is probably fast enough for the game they want to play, especially because it's an older game.

[inland dove]

My game performance seems to have been improved in space battles.

GC map is still pretty laggy though, but I don't think there is any fixing that without just building a desktop system with better components than what is in my laptop.

[mossy gull]

@inland dove does your CPU support DDR4?

[inland dove]

Yes.

I have DDR4 RAM.

[mossy gull]

From time to time I get broken laptops from people because I reuse some components.
If I come across a 16GB RAM stick I don't mind sending it up

[inland dove]

I appreciate the offer.

But I think I'll end up just saving for a desktop system and not worry about upgrading the laptop further.

[mossy gull]

Aye, fair enough

Just the offer still stands for a free stick if I find 1.

[inland dove]

It's possible that this small performance boost was the result of setting this priority to above normal and not forcing it into core 2 though.

I'm not 100% sure, maybe a little bit of both.

[mossy gull]

I usually throw away or give away RAM sticks
To me they're the most useless components to resell.
Literally if I sell them to a nearby shop I get 5.-, if I sell them to people I get scammed

[inland dove]

ooh that's interesting

I restarted my game and it reset the changes I made.

I think setting it to core 2 made it worse.

It's hard to tell.

It's probably not worth worrying about too much.

[mossy gull]

Yeah, to permanently save the changes you have to change something in the registry, but if you're not comfortable with that I wouldn't recommend it.
As doing something wrong can brick Windows.

[inland dove]

Well this has been fun.

I'll be headed on my way now.

[mossy gull]

Stay safe

[inland dove]

you too.

I wont brick my laptop (hopefully)

[mossy gull]

Just don't

[mossy gull]

Why, just why......

[cerulean helm]

Ugh, why is it so hard to find a pcie 4.0 to m.2 expansion card that has its own chipset on it for lane bifurcation that doesn't cost $500.
I can find pcie 3.0 expansion cards just fine for $200 or less.

[sonic meadow]

well if its got a chipset its probaly not doing lane bifurcation but lane switching, and those chips are expensive

[cerulean helm]

This one is pcie 3.0 and has the chipset on it and is on sale for $180. They just don't make one pcie 4.0.

Only one I found that is, has 8 m.2 slots and costs $800.

https://www.amazon.com/CREST-SI-PEX40129-Ports-Bifurcation-Controller/dp/B07HYZY7P2

[sonic meadow]

sounds about right tbh

[cerulean helm]

I need one thats pcie 4.0, with chipset and only 2 m.2 slots,

[sonic meadow]

that means its not doing bifurcation you silly product...

[cerulean helm]

No, that means it does not require the motherboard to have pcie lane bifurcation.

Because it has its own chipset.

Unlike the Asus Hyper m.2 carrier I have that does require motherboard to have lane bifurcation.

[sonic meadow]

ah, yup thats definitely a pcie switch

nothing bifurcation going on there at all

supports up to twelve downstream devices over 16 lanes

[cerulean helm]

It would enable me to install 2 m.2 drives into a single pcie slot and use both drives.

[sonic meadow]

here you go 😆 https://www.sonnettech.com/product/m2-8x4-pcie-card/overview.html
8 slots m.2 gen4 😛

[cerulean helm]

Thats the $800 card I was talking about earlier. Way to expensive and I don't need 8x drives.

[sonic meadow]

well do you Need gen4 speeds?

[cerulean helm]

The drives are gen 4, and the board has gen 4 (and 5 for the first slot), no point in not getting an expansion card thats gen 4 otherwise I'm just underutilizing a main feature.

[sonic meadow]

ahh, so you just want gen 4 but dont actually have a need for it.

ssds for consumer applications dont usually get much benefit from the higher bandwidths. we arent usually i/o limited by that point, typically processing limited (because we arent just copying stuff in to ram)

[cerulean helm]

Well this is interesting, Samsung Magician is not showing one of my drives having a volume, yet it shows up in disk management in windows and I have over 200 gb of data currently on it. Thats kinda weird.

Ah, its cause that drive is a dynamic drive.

[mossy gull]

Look for a RAID card

[jade scaffold]

Me and my inability to use the extra 8tb of SSDs in my pc because I don't got the pcie lanes

[mossy gull]

RAID controller

[jade scaffold]

Not possible

U.2 raid controllers cost a fortune

[mossy gull]

Fair enough

[jade scaffold]

Like £700 unless you wanna import from China

Is rather not have to spend £1400 on just raid controllers I'll take my chances getting a new cpu platform

Besides I do need better single thread performance my 3090 is bottlknecked most of the time

[mossy gull]

https://youtu.be/-n8N62DeNDU

[cerulean helm]

Still expensive af, like why are all of them over $350 for just a dual m.2 card?

[mossy gull]

Be happy, in the Netherlands the cheapest I can find is €500.-
Sadly in my server I needed 2 of them.

[stiff wing]

Afternoon, been looking around for a new modern-ish gaming computer for $800 USD. Been looking at Microcenter mostly, but thought I would ask here for suggestions before I pull any triggers.

[mossy gull]

My personal advice would be to save up more till you can get a PC with at least 12GB VRAM GPU.
There's games that run poorly with 8GB or less.

[stiff wing]

personally I just want a card with more than my current 2GB right now

could go intel a770...

[mossy gull]

What's your overall system spec?

[stiff wing]

right now or what I'm looking at?

[mossy gull]

What you currently have

[stiff wing]

I7-7700
16GB duel channel memory
Some crap HP motherboard
1TB M.2 SSD
GTX 1050

all in a non expandable case

think the psu is hp as well, non expandable

hence the thought of just getting a new prebuild

[mossy gull]

If you have a decent enough PSU(below 500w), go with the AMD RX 6700XT if you want to save money, or if you have more than a decent PSU like 500w or more get the AMD RX 6950XT.
Yes they're last gen GPUs, but they pack a punch

[stiff wing]

by non-expandable psu, I mean they have the bare minimal cables to run it as is, gpu is motherboard powered

[mossy gull]

Does the motherboard have a 24-pin cable on the right side of the board?

[stiff wing]

also I am limited to 1u card

bottom I think

it's mini-ITX I think

[mossy gull]

Doesn't matter ATX, M-ATX and ITX have them

[stiff wing]

the case is crap, the psu is crap, the motherboard is crap, and back to my just replace it

it's a 180w unit

[mossy gull]

Trust me, an 800.- "gaming" pc is also crap.

[stiff wing]

https://www.microcenter.com/product/666624/powerspec-g516-gaming-pc

[mossy gull]

But if your motherboard has an 24-pin motherboard cable, then you can replace the PSU for an 850w

[sacred seal]

You can get a very decent piece of kit for 800 if you self build

[stiff wing]

this seems good to me

yeah I know I could self build but don't want to

[mossy gull]

Just know majority of very cheap PCs have shitty PSUs and motherboards, it's how they keep the cost down.
So don't expect much.

[sacred seal]

You get more value for your money, and you generally get something that is upgradeable.

[stiff wing]

I'm aware of the possibility, one sec I think I had a list somewhere

[sacred seal]

I would guess that that pre-built would be 2-3x faster than what you currently have

[mossy gull]

They are
But I thought if they could keep the PC a bit longer, then they can have a much faster GPU

[stiff wing]

https://www.microcenter.com/site/content/custom-pc-builder.aspx?load=d3b98b6a-b737-4e29-a297-eaa1a48237e0
https://www.microcenter.com/product/5006270/amd-ryzen-5-7600x,-msi-b650-p-pro-wifi,-gskill-flare-x5-16gb-ddr5-5600-module,-computer-build-bundle

[stiff wing]

I understand your argument but it's a LGA1151

[sacred seal]

Odds are if it takes a single slot cards it's not a standard psu

[mossy gull]

I would get the previous 1, and maybe later switch out the motherboard.

[stiff wing]

Well the goal was to get on am5 and not be end of life on am4

[sacred seal]

The parts list is not awful, but I would not touch that case with a 10ft pole

Speaking from experience

[stiff wing]

cheapest I could find at microcenter, could reuse the 15 year old one next to me

[mossy gull]

I also would avoid cheap MSI motherboards, I had too much problems with them after 1 years of use.

[sacred seal]

I'm on mobile rn so I can't mock up an alternative

[mossy gull]

From dead PCIe slots, to dead RAM slots, to dead SATA ports.

[stiff wing]

I remember wasted saying the other day the industry as a whole has a reputation problem

[sacred seal]

Yea, you refuse to buy from a shitty vendor, you can't buy anything

[mossy gull]

Cheap MSI boards are the worst, I personally had more luck with cheap Asus and Gigabyte boards.

[sacred seal]

That's why you look at the skew level.

[stiff wing]

I think I have some months old list somewhere...

[mossy gull]

Last MSI board I worked with, was an Tomahawk, had 3 of 4 dead RAM slots and 5 out of 6 dead SATA ports, 2 year board by the way, oh, the M.2 was self destructive.

[stiff wing]

here it is, better?
https://pcpartpicker.com/list/z8hJY9

the gpu likely needs to be changed

[mossy gull]

The other PC you send, the crappy 1 has a much faster CPU and tad faster GPU

But I don't know what parts they used.

[sacred seal]

The mx330 is a way nicer case then what you had before

[sonic meadow]

Because they have a chip on them that costs like 100-200 dollars

[mossy gull]

@stiff wing
I did this very quickly, I have to get back to sleep soon.
https://pcpartpicker.com/list/bvcymr

You maybe can find a cheaper PSU, motherboard and case to keep the cost down, CPU comes with a cooler so don't worry about that

The 3060 is a bargain and actually has VRAM for days

You also can find Windows keys only fir like 20.- instead of 150.-

@sacred seal is this list maybe a better choice?

[stiff wing]

that looks good, I will consider it

[sacred seal]

That's closer to how I would part it out

[mossy gull]

For a budget build I would go for last gen

Gets you more performance

[stiff wing]

alright, was thinking it was too early to go to am5 anyways

$90 case? nm, I'm sure I can find something with mesh filter for cheeper

[mossy gull]

I tend to stay with Corsair and NZXT, but you probably can find cheaper.

[stiff wing]

I would as well, but case seems like the least bad thing to drop price on

[mossy gull]

@stiff wing NZXT H5 flow should be cheaper

[jade scaffold]

Fractal do good cases and some of the really cheap phanteks too

I'm also gonna need to solve my up and comming psu problem

[cinder lagoon]

what makes cases expensive is the development process:

• You need to ensure compatibility!
• You build many, many systems in them and look for things that could be improved (more space for plugging in cables, better maintainability, etc.)

The more expensive a case is, the better it was tested (and it actually makes a huge difference, as you find out by buying really cheap cases)
I would recommend just waiting on getting at least a medium quality case or buying used (but make sure all screws etc are included!)
You don't actually need a case right away

[jade scaffold]

got me sum new internet too and o boi is it fast

also symetrical

[ionic tusk]

The NUC going away is hard on me lol

Just convince my company to get some nuc extremes for convention pc

Ik they said they divest and will support partners in making NUCs

Just wondering do I have to pivot to a different PC I have to procure like atleast 4 more they do say they will support existing customers

[vestal stirrup]

This might be an odd question but trying to find the correct description/name of my hobby. I do a lot of homeserver stuff, things like proxmox and such, so a mix of hardware and software experience. If I were to do that as a job, what role would that fall under?

[sacred seal]

Server admin/tech

[vestal stirrup]

Can I expand on that?

[stiff wing]

What do you mean expand?

[vestal stirrup]

Like does it fall under just that category or can it fall under other other sectors?

[surreal moss]

Depending on the size and market of the company you’re looking at the job role will be as specific as shadow started out as broad as Systems Administrator

[stiff wing]

Well, last day of prime day sale and I come to realise most of the recomended list is not on sale. Plus add windows which is $120 I... I can't spend a $1000 on this. Plus my friend insists I get a prebuild. I just... what I am trying to say is does anyone have any suggestions for a system like what was recommended but with prime day sales?

[cinder lagoon]

I'd say "Network infrastructure admin" - I do something similar, except I also have the roles "Internal processes" and "Tech Support"...

[cinder lagoon]

not using prime day nor buying prebuilt.
Both will make you pay way more than neccesary.
I suggest you try sites like NewEgg or micro center or more local Stores (depending on your location, i have "NoteBooksBilliger.de" as an example) because if it's primeday they often have actual sales, not the fake amazon ones where they pump shit up a week earlier.
But you should look on pcpartpicker for your configuration because they support many retailers and also rebates.

Also: I've never really paid for Windows 10 Pro, I always went for the ebay bulk-sale-leftover keys for like 10 bucks

On another note:

I'm having problems with c++ which seemingly don't make sense:

class Specification_Info {
  unsigned int SI;
public:
  Specification_Info(unsigned int BitMap) {
    SI = BitMap;
  }
};

class Battery {
private:
/*
  */
  unsigned int designCapacity() {
    return SMB.fetchWord(address, 0x18);
  }

  /*
    */
  unsigned int designVoltage() {
    return SMB.fetchWord(address, 0x19);
  }

  /*
    */
  Specification_Info specificationInfo() {
    return Specification_Info(SMB.fetchWord(address, 0x1a));
  }

public:
  uint8_t address;
  unsigned int DesignCapacity;
  unsigned int DesignVoltage;
  Specification_Info SpecificationInfo;

  Battery(uint8_t Address) {
    address = Address;

    DesignCapacity = designCapacity();
    DesignVoltage = designVoltage();
    SpecificationInfo = specificationInfo();
  }
};

However I get the following error message:

C:\Users\Chaos02\src\SmartBatteryInterface.cpp: In constructor 'Battery::Battery(uint8_t)':

Maybe someone has some idea?

[sonic meadow]

  Specification_Info specificationInfo() {
    return Specification_Info(SMB.fetchWord(address, 0x1a));
  }
``` should this be `return new Specification...` instead?

since you dont have a function anywhere public with the name you are calling. its only as a method on a class

and you werent calling it on an instance of that class

[cinder lagoon]

...wait I want to construct a new Specification...
I should say I'm coding arduino rn and they seem to have changed some syntax some bit to make it more beginner friendly so that you don't use a new Keyword afaik

I just want to call the public constructor of SpecInfo

[sonic meadow]

new calls the constructor iirc

its been a while since I have done any c++ admittedly

and the arduino stuff (if going through the arduino ide) is a bit special

or was at one point 🤔

[cinder lagoon]

all my other classes work in this manner

its just this, why I came here ^^'

[sonic meadow]

can you post the relevant snippet of the class and how it was called?

just to see if you are doing something different

[cinder lagoon]

https://pastebin.com/QYBvG7HT fo sho

note that i had commented the problematic bit out by now

[sonic meadow]

I said relevant snippet 😛 I didnt really want to fish through 500 lines right now 😆

battery_mode looks to be doing the same thing 🤔

[cinder lagoon]

ohh I forget that ctrl + click and find all references doesnt exist on pastebin ^^'
relevant lines are:

• 83 class Battery_Mode
• 178 class Battery_Status
• 230 class Specification_Info
• 339 Battery Public parts
• 364 BatteryMode()

I've already tried setting the Spec field directly with the constructor but same result

[sonic meadow]

honestly I cant see why its not working /shrug

[vestal stirrup]

There are so many different labels now

I've been eyeing up a new phone for a while and I love how this one looks

[cinder lagoon]

you seen the first one? its almost exactly the same - if you don't need the greatest camera get the first one instead for way less money!

i have it and its great

[surreal moss]

That sounds like the better option. Figure if I’m spending that much might as well stick with iphone

[cinder lagoon]

just their OS is a few sometimes a tiny bit wonky

[cinder lagoon]

if now there are any c++ gurus here - any input on this convo?

[surreal moss]

Been a long time for me but I think I’d be looking at the initial declaration of Specification_Info

[cinder lagoon]

Read the other couple messages following - I already answered most of the questions here

[jade scaffold]

the issue with the Nothing 1 is the poor battery life and the RAM

the main issue with my current phone is it doesnt have alot of ram

so everythings a bit sluggish

especially when i got all my work stuff google and discord open

[cinder lagoon]

what do you mean poor battery life??? mine literally lasts me two full days before I need to recharge it and I use it 3-4 hours a day

[cinder lagoon]

phone two has the same RAM options - 8G and 12G

[cinder lagoon]

nothing (hah) on it is sluggish. nothing gets in the way. The OS sometimes has a little hang up when dealing with login or power button

biggest feature for me: not bloatware

[jade scaffold]

20hr of battery life vs 25 hr and it's processor is also the same one in my current phone which is ok but not particularly great again when dealing with things like chrome and discord and such being open at once

Does the nothing 1 have dual sim?

[surreal moss]

I’m talking about the class, mot the constructor

[cinder lagoon]

the entire file is in the pastebin link following

[cinder lagoon]

here

[cinder lagoon]

yes, dual sim - everything I had open at once ran fine but I do not do heavy multitasking

[jade scaffold]

aparently the nothing phone 2s software is alot better too but i heard somthing about them migrating the newer software to the nothing 1 too

so ill wait a bit see what happens

[cinder lagoon]

there is neither a guarantee that they'll do that nor a statement - quite the opposite: they "don't know wether they'll do it or not"
Its not such a big deal tho

[jade scaffold]

kinda is a big deal to me the software of the Nothing 2 is whats selling it for me the better CPU and battery life are great too but the software of the nothing 1 is natoriously a little jank and ive had enough a little jank from my current phone

[cinder lagoon]

I wouldn't really bet that its less jank but I wasn't very invested in the phone 2

[jade scaffold]

Yea I should probs wait for it to come out proper and see what people think of it

[cinder lagoon]

you could also go on the Nothing Discord but odds are that your opinions (by each one) will be skewed, if getting multiple tho probably an accurate image

[jade scaffold]

i really like how the apple esque design look i want good battery life and a phone that can handle me having far more than is reasonable numbers of things open at a time

Noice but its significantly more gray than I thought it to be

[jade scaffold]

yup its very much grey

though honestly lighting conditions really do effect what it looks like

[mossy gull]

I discovered something.....nice?
If your system has an AMD APU or CPU with iGPU and an AMD dGPU.
When the GPU uses shared memory, it 1st uses the 512MB VRAM from the APU or iGPU

Also, there's a rumour where AMD 8000 series APUs will have 40 CU Navi 3.5 GPUs, that's stronger than the RX 6700 which has 32 CU Navi 2 GPU.
Which is insane.

[cerulean helm]

I'd say my OC and undervolt is quite successful.
Max 1 P core 6ghz with the next 2 at 5.9, 5 P cores at 5.8 and the last 3 maxing at 5.7. All E cores at 4.4.

This is on a 13700k.

[jade scaffold]

as well as being guarenteed to be total bs

as the most powerfull amd APU at the moment is the ones in the current gen consoles which uhhh arent even close to that fast despite having Enormous power budget dedicated to graphics

so unless AMD are gonna build a APU that pulls 200w which is very unlikely i doubt we'll see such a thing

not to mention where the hell is that kinda GPU meant to be fit

theres not all that much room on AM5 chips as is for chiplets and you cant really rearrange the chiplets too easilly to make more space for a dedicated GPU

also CUs are very poor representers of rendering performance

when comparing I GPUs to desktop GPUs because desktop GPUs also have a metric shit tonne of stream procesors and APUs generally have alot less

[sonic meadow]

there is also another big different between dGpus and iGpus, the memory bandwidth. vram is setup in such a way to get massive bandwidth, especially compared to a systems main ram

[jade scaffold]

yea that too

and overall clock speed

mainly because of vastly reudced power concumption

as having a too power hungry gpu sat practically next to your CPU will kick the CPUs performance in the balls

[sonic meadow]

thats an implementation detail really. they could have higher power targets, but you have packaging issues, as well as sharing it with the CPU. plus of course with the reduced memory bandwidth they dont work as well inteh first place

[jade scaffold]

the Ultimate APU is one with onboard memory

sadly to make such an APU youd have to sacrifice one CCD to the GPU gods

and find somewhere to cram some HBM

then you could actually have a ultra efficient APU especially if you use the Cut down version of x86

[sonic meadow]

wikipedia has the bandwidth of DDR5 listed at 32-64GB/s, where the RX 7600 has a memory bandwidth of... 288GB/s

[jade scaffold]

and 288GB/s for a GPU is also still really fukin low

the higher end bois range closer to the 1000GB/s

[sonic meadow]

yeah. I deliberately grabbed a "cheap"/lower end card for my comparison

the 7900 xtx is 960GB/s

[jade scaffold]

yea

though again in theory not impossible for AMD to make a baller APU i mean they already made the MI300 they could in theory super shrink the concept

but a smaller AM5 varient with how crammed it would be comparitivly would run HOT

i mean youd have CPU cores a GPU HBM the IO Die all crammed into a space maybe 2cmx2cm

[sonic meadow]

the 7600 core is only about 15mm square, (204mm^2), which is plenty fittable on an am5 pcb. though as you said without one ccd

[jade scaffold]

yea it could fit

though you couldnt fit it in place of 1 CCD its still even too big for that

[sonic meadow]

I always thought it would be more interesting to try with the TR platform though, you have the much bigger socket, and the extra memory channels (4 early, 8 on TR pro I think) to help with that issue

[jade scaffold]

people under exstimate how much space is under that heat spreader

[jade scaffold]

well on the Epyc platform we do have MI 300

[sonic meadow]

oh yeah, that thing

[jade scaffold]

128gb of HBM3 24 CPU cores

its got alot of GPU tiles

i think 3 of tyhem if i remember correctly

14k shading units 880TMUs 220 Compute units

oh and just a tiny power draw of 600w

[sonic meadow]

heh

and thats why... watercooling (also this is a blade, which have space constraints... but whatever)

[jade scaffold]

like look at how crammed that is

[sonic meadow]

die shrink the io chiplet

[jade scaffold]

that would be expensive

you'd have to shrink it

move it to the side move 1 CCD right next to it

then under it you would have to have a GPU tile and then a HBM tile

tbh in theory a HBM tile of that size could be like 64gb or 32gb or somthing which is a hell of alot of built in RAM

and would be especially good as a shared pool

i wonder how HBM3 compares to L3 cache

[sonic meadow]

higher latency if nothing else I would be guessing

HBM gets its bandwidth by being silly wide right? even more so than GDDR implementations

[jade scaffold]

yea

8192bit or some shit

which like obliterates anything GDDR does

GDDR tops out at 1024bit

and 1 module of HBM3 alone is only 100 GB/s short in data trasfer rates of a 7900xtx

which is crazy

which means with chips of HBM3 on something youd be doing like 1.7TB/s which is a frankly absurd ammount

[sonic meadow]

though cache doesnt always compare in a meaningfull way (its usually more latency tied, not always especially wide)

not mine, just what I found when digging online

[mossy gull]

The 6800M uses around 100w.
The CPU part only has to pull 45w.
So you actually already can make a powerful APU.

[mossy gull]

CPUs these days pull more than that these days funny enough

And X3D chips usually sit around a snuggly 35-45w when gaming.

So AMD could pull off a very powerful APU

[jade scaffold]

except for they cant because they cant fit much on an AM5 CPU

the best apu currently is pathetically weak if you compare it to any modern dedicated GPU

it doesnt even compete with a 4 gen old mid range gpu

excluding the MI300 that is but the MI300 is missing most features that a GPU has making it kinda hard to call it a GPU because it cant actually do graphics

[sonic meadow]

it will also cost more than a top range gaming rig. on its own

[mossy gull]

The RX 6800M is tiny, like as big as a single CPU die.

[jade scaffold]

LMAO

it is not that small

[mossy gull]

It's small, my laptop has 1, it fits in a CPU package

[sonic meadow]

335mm2, or a 18.3mm square

[jade scaffold]

then youve been ripped off because its 335 square mm

[sonic meadow]

which would you believe is a similar area to cpu silicon?

[jade scaffold]

the CCD on Zen 4 is 70mm2 squared

[sonic meadow]

however the package area is more tied to pin count than silicon area

[jade scaffold]

this is true

but you need thoes pins

you cant just like shrink the pin area without quadrupling the cost

[sonic meadow]

I could fully see a 6800m having a similar package area to a laptop cpu

[jade scaffold]

thats bacause laptop CPUs are Monolithic though

[sonic meadow]

heck, most of the laptop chips I have seen have been similarly sized

[jade scaffold]

yea

a 6800m would fit on an AM5 CPU

but you couldnt then have an IO die or and CPU cores or any onboard memory

meaning its gonna be turbo bottleknecked by lack of memory bandwidth and also then its just a GPU in a CPU socket not an APU

[mossy gull]

What about, we'll see what happens.
The Navi 3.5 40CU can be the same size if not smaller than the 6800M

[jade scaffold]

so no we cant have turbo powerfull APUs unless AMD shrink the IO die drop a CCD and cut the size of their current GPUs into a 3rd their origional size

which last i checked it was literally not possible to go 3x smaller than than what we currently have without running into serious issues electrons

[sonic meadow]

well we could have turbo powerful APUs, but it wouldnt be using their desktop/laptop chips. it would still be a cut down version of their larger siblings

which they have done before.

[jade scaffold]

and it would still likely loose to a 4 generation old desktop GPU

[sonic meadow]

admittedly they let intel do the CPU on Devils Canyon

or was it a different one? I dont really remember anymore

[jade scaffold]

it was a weird one

i dont remember it too well

[mossy gull]

The 6800M is a pretty powerful GPU though, in some games as powerful as the 6700 if not the XT variant.

[jade scaffold]

yes it is

but you cant shrink it by 3x the size

which is what would be nessesary to cram it onto a CPU package

unless you are fine having it utilise main memory for its memory

[sonic meadow]

at a third of the size you have a 6550m (107mm2)

[jade scaffold]

which will kick its performance so hard in the balls you may as well just buy a second hand 1080

[mossy gull]

But if the 40 CU Navi 3.5 is the same size as a 32 CU Navi 2, then you could fit it in a CPU/GPU package

[sonic meadow]

at which point you have to package a full discrete gpu

[jade scaffold]

CUs are awefull representers of performance

especially for rendering

[mossy gull]

All they said was 40 CU Navi 3.5 at 2.5GHz.

[jade scaffold]

who said this

is it from any reputable source or is it just from one of thoes hardware channels that over hype literally everything that might come out

so far the only APU i can find that might end up having 40CUs is one designed for embeded systems

all the leaks point at the actual socketed CPUs only having 16

performance estimations still only put the 40CU "apu" at competing with the 4070 maxQ which is a low end GPU Given a high end designation if ever i have seen one

which is about as fast as a 1070 desktop which dont get me wrong is good performance for something clearly designed for mobile devices like hand helds or laptops though the power draw of the entire package would be at a minimum 60w not making it particularly efficient and probably only the low end varients of it will make it into hand helds

[mossy gull]

Who knows, AMD put a decent APU in handheld devices that are strong enough to embarrass the GPUs twice the size.

[jade scaffold]

except they didnt

the only gpus that were that much bigger than them that they embaressed were ones from 3-4 generations ago

when the size of the nodes GPUs were built on were literally 2x the size

[mossy gull]

The Z1 Extreme/7840U are as powerful as the GTX 1650 Ti.
Which is currently 1 of the most popular GPUs

[jade scaffold]

and is also a gpu 4 generations old

being literally node shrunk pascal

also the 1650 ti is strictly a mobile GPU its only just as fast as the desktop 1650

[mossy gull]

Then I meant the 1650, seriously NVidia is confusing

[jade scaffold]

which was if you remember relentlessly bullied for being a slow peice of shit

if this new 40CU APU is actually going to be a thing its not making it into a hand held

probably into some thin and lights maybe as it will take up less space than 2 seperate CPUs and GPUs

so more room in for cooling it

which would be interesting atleast

[mossy gull]

It's so far I think meant for either laptop or desktop.
If it's a 100w chip it would be very very efficient laptop APU

[jade scaffold]

its not meant for desktop

we pretty much know so for a fact that it wont make it into a desktop chip

[sonic meadow]

the leak claims 120w for the apu

[jade scaffold]

wait really

thats horrendously inefficient

thats actually awefull

[sonic meadow]

do you even know how efficiency works in cpus/gpus?

because you have used that term a few times now

[jade scaffold]

im saying power consumed for performance

[sonic meadow]

which tends to go waaaay up as you go to lower power chips

[jade scaffold]

120w for a CPU that has 12 cores and a gpu thats only about as fast as a 4070 Max Q

[sonic meadow]

a 75w laptop part has way more than twice the "performance" of its 150w desktop counterpart

[sonic meadow]

as fast as a... 115w part

[mossy gull]

The 7950X3D has a TDP of 125w, but people say it's often around between 65w in games because of the X3D

[jade scaffold]

the 4070 maxQ is 35W allegedly

[sonic meadow]

oh wait. the maxq is 35w. nevermind

[jade scaffold]

YEA

[sonic meadow]

i was going off wiki, which didnt list it

[jade scaffold]

do you get where im comming from

im not comparing it to a desktop 4070

[mossy gull]

That's why the Max-Q were just dumb

[jade scaffold]

im comparing it to the MaxQ one
which is what the leaks say its competing with

[sonic meadow]

I was looking at the mobile one. which has a tdp range of 35-115w. which compares to the leaks tdp range of 20-120w

[jade scaffold]

the leaks compare it to the Max Q varient

theres not a chance in hell this thing goes anywhere near 120w thats far too much

[sonic meadow]

to the 4060 max-q

[jade scaffold]

im seeing 4070 maxQ for the 40CU one

[sonic meadow]

The GPU side gets an even bigger upgrade with up to 40 RDNA 3.5 CUs in 20 WGPs plus 32 MB of on-die infinity cache. This is expected to perform similarly to RTX 4070 & RTX 4060 Max-Q GPUs.

hmm. though that could mean either the 4070 or 4070 max q. I hate english at times

[jade scaffold]

The Strix APU series would compete with up to RTX 4070 Max-Q GPU in their 40CU configuration

from Moore's law is dead aparently

i find this statement to actuall make more sense than it even touching the full fat laptop 4070

as if your statement is true it means AMD have more than trippled APU performance in one generation which is just very unlikely

the 4070 MaxQ statement would suggest a arround 35-50% increase in performance

which makes alot more sense for a generational improvement imo

[sonic meadow]

however... the closest zen4 mobile chip (7645hx) is a 55-75w part. if we assume the new chip has a similar draw (ie probably about 50w), then thats around half the power budget. leaving ~70w at the high end of the stated tdp

[jade scaffold]

yes but i belive that might mostly go to the CPU

as reading through other leaks there seems to be potential for a 16 core CPU

[sonic meadow]

7645hx is 16 core, the reason I used it as a comparison

[jade scaffold]

as well as some lower CU count and substantially lower clocked varients

huh

[sonic meadow]

I would have expected a bit more comparitive performance for the power levels. but if nothing else, the 40 series chips are stupidly efficient, especially at the shittier skus

[jade scaffold]

the 40 serise generally is silly efficient

really its efficiency shouldnt have been enormously higher than 3000s
the only reason the effciency is so good this gen is because NVidia wanted to make the 4090 a think which to get that kinda performance nessesitated a node shrink if they didn't do that then this gen would have been much like Turring was to pascal just slightly more efficient then overclocked a bit. which you can really see in how the 4090 pulls so far ahead of everything else NVidia are offering

[sonic meadow]

efficiency is good for a few reasons. one of them being that they arent pushing them as hard as the 30 series chips

[jade scaffold]

yea 3000 isnt very fun to overclock because of that

unlike the 1080ti my beloved

clock speed improvement out the ass from a CPU water cooler crammed onto it and alot of tweeking

2115 MHZ on the GPU core

[sonic meadow]

I guess the big question is: what tdp were they making that comparison at? were they doing it at the same gpu tdp? were they comparing the chip (in a test system) against another system using the chip (ie looking at system load and performance, not part load/performance)? are they blowing magic smoke out of their arses?

as with all leaks, it says what amounts to be a lot of nothing when you look at it harder

[mossy gull]

Or an APU with 35w CPU and 90w GPU?

[jade scaffold]

really imo if an APU cant shift its power arround its kinda shit

like if both the CPU and GPU have access to the full power then what you can do is shift the power to optimal conditions for what ever task you are doing
