If you can find what it is without the black heat shrink we can probably work something out but it will probably require soldering

[mossy gull]

I don't mind soldering, as long it eliminates the constant replacement

[cinder lagoon]

It most likely will.<

Do you have pics of the insides on hand?
If the Battery has some wired cable connecting it to the board it might get even easier actually

You most definitely will need:

• a multimeter,
• the main batteries voltage specs,
• the CMOS chip voltage specs (or maximum available cmos battery current)
• and depending on how much that current is either resistors or some other component to step down the voltage

[sonic meadow]

its probably just a standard coin cell with tabs spot welded on.
coin cells can be identified by their size (ie measuring them). A CR2032 for instance is 20mm diameter, and 3.2mm thick

[cinder lagoon]

Cmos batteries seem to be 3V

[cinder lagoon]

Its also stamped in all of them (under that short-circuit-protection called heat shrink)

Main battery voltage differs depending on model tho

[mossy gull]

I send a pic above which 1 the laptop uses

[sonic meadow]

yes. you sent an image of one that has stuff on it that obscures all the useful information about what it is

I also cant measure stuff from a single image with no size references 😛

[mossy gull]

I haven't seen 1 of those that's a different size, it seems to be mostly 1 size.
Only the connector at the end can be a bit different.

[sonic meadow]

coin cells (in general that is) come in a wide variety of sizes. hearing aids, car keyfobs, and pc cmos batteries all use different sizes of coin cell for example.

and laptops being.. entirely lacking in standard as it is will not necessarily use the same as a pc motherboard

[mossy gull]

But the CMOS usually are the same size.
Although lately on laptops the main battery also works as CMOS

[sonic meadow]

yes, cmos on PC. laptops do whatever the fuck they want

[mossy gull]

They still are the same size, or well, overhere they are.

[cinder lagoon]

WELL, open that thin up, remove the plastic wrap and snap a pic
and if you actually want to do it post a pic of the main battery with its connector and specification printing visible

[cinder lagoon]

Regarding my IO board problem... I was able to get that burnt bugger off in one piece... Now to see wether the resistance values of the area match the schematic...

[cinder lagoon]

Seems good, no shorted pins anymore, I²C pins are also completely unconnected while off.

[cinder lagoon]

Guys have you ever seen an abomination like this??
This seems to be a PCIe gen2 x1 packet switch board. So far so good.
But the PCIe CONNECTOR JUST BEING A CUTOUT WITH ANOTHER PCB STUCK THROUGH AND SOLDERED?!?

[jade scaffold]

Okay so while im not saying its a good idea what i am saying is in THEORY one of these could be crammed onto an M.2 i believe though maybe only just about, not sure if you could then cram memory VRMs and all that lot on with it buuuuut the GPU itself could fit do with this information what you will

[cinder lagoon]

Hmmm... given that this is about able to do 1080p60 in low to medium current forza horizon thats actually a pretty nice thing!
If you can cram like 4GB of VRAM onto the M.2 aswell that would actually work probably and be a reasonable choice for accelerating low power laptops (although with a cooler sticking out)

Or 1030 usecases

...whichever seems more sensible to you ;)

[jade scaffold]

i think Theoretically speaking it should be faster than the Steam Deck GPU its only slightly slower than a gtx 1650

though i think if you can make GDDR6X work with it which GDDR6x is the same as GDDR6 but like turbo overclocked so in theory you can massively increase memory bandwidth as it has really low memory bandwidth by default and i actually think thats whats limiting its performance

[cinder lagoon]

Gpus have memory controllers too tho

[jade scaffold]

only a 64bit bus at 96GB/s which is only slightly faster than DDR5 5200 i believe

[cinder lagoon]

So just slapping faster stuff might not be enough

[jade scaffold]

yes its about if the memory controler will accept the different single timeing of GDDR6X

or even if it'll accept full on GDDR6

though if you could get GDDR6 and get a hefty memory overclock you could get a decent ammount of extra performance you can quite easilly get +1ghz ontop of the base memory speeds usually its not the mem controler thats the issue on gpus you actually tend to hit the memory stability threshold first

[cinder lagoon]

Dont forget about cooling tho

[jade scaffold]

put memory on the back of the m.2 strap one of thoes air jets to it as well as the VRMs that should keep all that nice and cool

Keeping the GPU itself cool it can in theory go upto 30w

so just strap a M.2 liquid cooler to it maybe

[cinder lagoon]

I think all high-power components must be on the top side for cooling so probably only 2 chips so reduced memory bus aswell.

[jade scaffold]

ore like

[cinder lagoon]

DerBauer recently did some M.2 cooler comparisons

[jade scaffold]

its got a 64 bit bus i'd be surprised if it supported any more than 2 Chips

you definatly to fit everything on have to put things on both sides

[cinder lagoon]

power conversion etc

[jade scaffold]

VRMs dont get hot especially not for a diddy little 30w GPU though i believe M.2 is only like 3.3V power

also they can only do like 15w power total so you need external power of some form

sata power maybe 4 pin CPU EPS or 6 pin PCIE or 12V HPWR any of which should provide the nessesary power

[cinder lagoon]

So for a GPU you would probably want 4 PCIe lanes -> only M (+B) key is viable.
https://images.anandtech.com/doci/13609/m.2-ngsff-conflicts.png

[jade scaffold]

oh also Air Jet Dev kits are now available so you can have active cooling on the rear side to cool VRM Memory or what ever

its a gpu that can barely do DDR5 speeds of memory transfer i dont think the M.2 Slot is gonna be a bottlekneck im gonna be honest

[cinder lagoon]

Oh good point!

[jade scaffold]

not sure if they would be good enough to cool a 30w GPU

but they could atleast cool off the rear components as well as sap just a little bit of heat off of the GPU die through the back maybe only 1 or 2 degree but every little bit helps

[cinder lagoon]

Active airflow really does help alot.

[jade scaffold]

Reasonably speaking from an electronic sense how complex do you think designing a PCB for this kinda device would be
most of the complexity is going to be in the Power delivery right?

[cinder lagoon]

I think so?

You could basically copy the schematic of a laptop with an mx550 tbh

[jade scaffold]

if i could design the PCB i could have PCB way construct the entire PCB and mount all the surface components minus maybe the GPU which i would have to fetch myself but it might be doable

[cinder lagoon]

Its pretty old tho so I would rather try fitting a newer intel "integrated" GPU

[jade scaffold]

just like stick one of these on the rear side memory/VRMs or what ever the hell you'd cram on there

[jade scaffold]

im not sure thats possible

MX550 is Turing yea if there was an ADA varient you could get the same performance at like 15W which would be Insane for constructing an ultra tiny Gaming handheld

the issue is M.2s are only 22mm wide you could get away with adding an extra 1.5mm in width on if you wanted i guess but not much more than that to ensure compatability

[cinder lagoon]

You will also need a bios (and bios chip) and you probably can't just use one from another nvidea gpu lol.
BIOS modification etc is a viable way if you know the right community. There's BIOS "hackers" for GPU specifically in the extreme overclocking scene already

[jade scaffold]

also all of Nvidias stuff got leaked a while back

pretty much everything pre Ada i think is in effect "open source" not really open source but its out there

i mean if i get my MX550 from a dead laptop Could i use that GPU Bios chip from said laptop?

though im not sure how angry bios gets with using differeing ram

one of my big goals would be to atleast double the available ram to the GPU

[cinder lagoon]

Bga reflow is expensive.

[jade scaffold]

which you can just get bigger memory modules over an identical interface and ive seen people like tac them onto 3070s to give them 16gb

[cinder lagoon]

Yes but it did not work without issues

Absolutely not at all

[jade scaffold]

but is that a Bios thing?

[cinder lagoon]

Note sure

[jade scaffold]

bucause the 3070 GPU like the actual GPU itself does support more VRAM because the Quadros exsist and use identical silicone

so that has to be a bios/Driver issue which hopefully NVidias everything being vomited onto the internet should be solvable

[cinder lagoon]

I'd guess so tho because the BIOS communicates things such as memory requirements etc and it receives address spaces by the CPU BIOS i think

[cinder lagoon]

Afaik its not open source but paid somewhere on the dark web. Someone might have published for free tho

[jade scaffold]

2gb on an m.2 is fine too i guess

but 4gb would have been nicer

[cinder lagoon]

There's always a way up, once you get the "minimal modifications" version running

[jade scaffold]

if you could get GDDR6X working thats a 1.4x Increase in memory bandwidth too taking it from a piddily 96GB/s to like 130+GB/s which is i think rather substantial

oh also the GPU supports PCIE 4 x8 so PCIE 4x4 bandwidth should be plenty for it

[cinder lagoon]

Exactly

[jade scaffold]

I wonder if its succeeded by anything

[cinder lagoon]

Have you seen any nVidea low power laptop GPUs?

recent ones at least?

[jade scaffold]

the 3050 GPU actually has the Same die area as the MX550 buuuuuuuut the substrate is like 50% bigger so it wouldnt fit on a M.2 :(

[cinder lagoon]

Well it also is not particularly low power...

[jade scaffold]

and like the 3050 is so much faster

you can run even lower power on that you could easilly down that to like 30w and get like double the performance still

[cinder lagoon]

It also has so many more bga pins :P (I mean why would the substrate be bigger if not that?)

[jade scaffold]

yea

though 1 moment

GA107S and GA 107SB maybe?

the GA 107SB seems like a direct Successor

25w TDP though can be configured to 30W
Double the Cores Tensor Cores RT Cores Interestingly though no NVENC

MX570 yea it is a successor

[cerulean helm]

Well that was interesting. HWinfo had an update (I have the pro version) but the auto update failed with an error message unable to install driver. Turns out, it required a Windows 11 update to be able to get the new HNinfo driver.

[jade scaffold]

interesting

[cinder lagoon]

Huh damn

Did you close the HWInfo application before installing?

Because it always interferes

[jade scaffold]

OOO Theres a quadro version of the MX570
the A1000 Laptop uses it 4GB of GDDR6 on a 128 Bit bus 224GB/s it has 2048 Cuda Cores 64 Tensor Cores 16 RT Cores 35w Max TDP

its the Same size thats Crazy

[cinder lagoon]

If you look at this wiki entry you can find all nVidea GPUs with die size, many are very similar.
Substrate size seems to not be included tho
https://en.wikipedia.org/wiki/List_of_Nvidia_graphics_processing_units#GeForce_MX_series

[jade scaffold]

the A1000 is the best you could get Same size as the MX570 and MX550 but much bigger memory bus more memory
sadly there isnt an Ada version of it but ampere is good enough that gives you access to DLSS2 atleast which is kinda insane to have on such a smol boi

[cerulean helm]

I have the pro version that has an auto update feature. Doesn't require you to manually close the program as it does it itself. And even with it closed it gave me a driver error message stating it cannot be installed. Gave a message of check is user folder is encrypted, close antivirus, ect.

Installed the windows update and HWinfo opened fine.

[cinder lagoon]

How are you finding these? I cannot find seemingly any information about BGA substrate sizes

[jade scaffold]

oh im pixle mesuring substrate size based off of given die size

not super accurate but accurate enough to give me a ball park figure

also VRMs might not be that complex look at this Jetson Orin which is also a 35W part

[cinder lagoon]

That connector is specifically designed for this and I'm willing to bet it already provides all voltages that the substrate needs

But it should not be that much harder

[jade scaffold]

nope it just has 12V inputs

all the power conversion from 12V is done on that little board

[cinder lagoon]

Thats surprising

Hmm maybe you can get BGA compatible sockets for your test board I think that would be highly beneficial

[jade scaffold]

need to like actually find a place to get the GPUs i'd wanna use

[cinder lagoon]

i think louis rossman has some documentation on where to best get part donors

you will have to pay for reflow tho - maybe multiple times -, I'm fairly certain of that

[jade scaffold]

at that point its worth paying for ones own BGA station

aparently you can get old ones for somewhat reasonable prices

[jade scaffold]

look at that tiny SOC that would fit on somthing the size of a M.2 though its an SOC so whats the point at that point
maybe theres another funky use i could figure out for it
i know the Tegra X1 can run Android the Tegra X2 was never seen in a shield so i dont know if it can run android but if it can that could be nifty because the X2 unlike the X1 is pascal

it can aparently Run Lineage which is a community distro of andorid
that opens up the question will my NX run lineage i should test that if so i could make it run Dolphin

[jade scaffold]

WAIT
Lineage Runs on my Xavier NX through an Unofficial Build
which is NVidia Volta Based which is much much faster and newer
huehuehuehue
gonna run Space Engineers on an NVidia ARM SOC and no one can stop me

thats if my Xavier NX survived its little accident where a capacitor on the Break out board caught fire which killed my M.2SSD i was using on it :( and the daughter board

[jade scaffold]

I really hope it survived I loved this thing

[jade scaffold]

Saw this carrier thought it would be perfect for a goofy super low profile Jetson build then my world was shattered by the stacked usb ports and ethernet in it

Why couldn't you just be thin

[jade scaffold]

Ya know what screw it it's good enough I just need a functioning carrier

[sonic meadow]

Can always remove the ports if you need it smaller

[jade scaffold]

True it's only usb as well I can probs just solder wires to where the usb ports once connected and wire them to some 3.0 type Cs

[jade scaffold]

They look through hole mounted to me removing them might be super easy

[jade scaffold]

pfft

[mossy gull]

Okay, good news, it's a standard CMOS battery, you know, coin cell, bad news, I am waiting for Dell to send me a replacement battery cable, had to lie that mine broke during a battery swap😅

[cinder lagoon]

Wait what why?

Do you mean the cmos cable or the main batt?

Or did you already attempt to do the mod?

[mossy gull]

Main battery, lets say I don't want to ruin a battery cable without having a spare

[cinder lagoon]

Ahhh I see

Do you have a pic of it?

Because you could try to solder to the board instead, it would probably just be very smol and fiddly

[mossy gull]

Nope, keep forgetting to make 1, but turning off the system pretty much will break the keyboard's firmware because the BIOS is resetting.
Thank you Alienware for the trouble🤣

[cinder lagoon]

Ahh crap lol

I'd really need a pic of the cable to advise what would be the best option so try keeping it in mind

[mossy gull]

It took me 5 hours to fix it yesterday, not gonna reattempt unless I have insurance it'll work without breaking

[mossy gull]

I know, but currently it's turned on more than 14 hours

[cinder lagoon]

If you have a diode on hand it would also be helpful actually. It needs to open at like 2V and block up to 12V in reverse

Also battery information is needed so we can choose the stepdown-method

[mossy gull]

I know, I also had to throw out the battery because it was pregnant.

the Solidigm D7-P5810 is an interesting drive

Its super super low latancy

not quite as low latancy as optane
53us vs 35-40us but at half the price for capacity thats pretty increadible

[cinder lagoon]

Expected TBW?

Because optane was insanely reliable

[jade scaffold]

50 full drive writes a day on the 800gb drive

for 5 years

i belive Solidigm is actually a company that split off from intel

so its no wonder they are offering the same kinda tech

they actually use the Same SSD enclosures that Intel do though their drives arent actually optane drives as that tech is pattented though theres reasonably a chance intel open source it much like they did with Thunderbolt

theres also the D7-P5620 which is a lower end version with all the same latency advantages but slightly slower on read write speeds more capacity and a 10th the endurance though a 10th the endurance still translates to 8700TBW more than pretty much any consumer SSD that exsists

i wanna see if they do a Mini M.2 version

i can then slap it on my jetson and have the os boot in like 2 seconds

[cinder lagoon]

Much of the boot processes still seems to be main board firmware and OS to hardware initialization so - sadly nope :(

[jade scaffold]

on consumer boards board boot stuff takes less than 5 seconds if you just turn quick boot on

the jetson already booted pretty quick

its not really got much of a bois firmware

unlike my super micro board which takes forever to boot

which isnt going to be helped by me adding an aditional 10 channels of ram in the future cant wait to spend 8 years in memory training because AMDs Memory controler is genuine garbo

[cinder lagoon]

Yeah true industrial stuff tends to take AGES...
I never use quickboot because you never know when you need to access the bios lol

[cinder lagoon]

Huh? Boilerplate copy-paste eula or is helldivers coming to IOS?

I would also like you all to hover over the Armco server icon

[jade scaffold]

my asrock board is fine

it boots fast

its a server board its got IPMI

this super micro board just wants to be a pain

Nothing that should be documented is documented and everything that everyone with a super micro board already knows is heavilly documented

[mossy gull]

Why do people keep thinking that HDR400 should offer a good HDR experience.
HDR400 allows for 8-bit colours, HDR content is usually at least 10-bit, which HDR600 needs to have.

[cinder lagoon]

Because its labeled HDR duh - pitchforks to VESA!!

[mossy gull]

It's even more fun when a monitor manufacture claims HDR10 or HDR1000, which are more or less open-source.

[mossy gull]

Okay, 1 thing I don't understand.
Someone on Reddit says they can't turn on 3 3440x1440 240Hz onto their 4080.
To me that sounds weird because I have 2 3440x1440 240Hz, 1 3840x2160 100Hz and 1 3840x2160 60Hz on a 7900XTX and it runs fine

[sonic meadow]

It sounds weird because you have a completely different card with different capabilities?

[mossy gull]

It sound weird because I have more displays with a much higher output

[sonic meadow]

On a completely different card from a completely different vendor

[mossy gull]

My brother has 2 3440x1440 240Hz and 1 3840x2160 100Hz, and it runs fine on a 4090, so I don't understand how a 4080 can't do the same

[sonic meadow]

Which is less than what the person you mentioned tried

[mossy gull]

I thought it's around the same as 3440x1440 120Hz, which need a HDMI 40Gbps

[cerulean helm]

So I'm getting a ton of stornvme errors in the logs. I believe its because I may be oversaturating my pcie lanes available. But its only 3 devices that keep showing up in the error log.

ASRock X670E Steel Legend

[sacred seal]

Yea, that is a good deal. Looking at about a 1800$ parts list

I guess closer to 1900 actually, which makes the retail price of 2500 seem crazy

[frozen igloo]

It would be ~1520 after taxes, would be 5 hours of driving and about 30 dollars of gas, do you think it would be a good purchase if you didn't need a computer right away but plan on getting one soon rather than later?

[sacred seal]

On a pure price biases it seems quite solid.

I love this weather prediction tech

thats so cool

[sacred seal]

I wonder how long until that kind of tech reaches consumers. One of the few subscriptions I pay for is "accurate" weather forecasting

[jade scaffold]

on another note as well a whole stack of racks of the upcomming B200s does actually act as a GPU if you have a pytorch program built for single instance it will run across all Blackwell GPUs in a stack

[jade scaffold]

very very soon

pretty much as soon as blackwell releases

infact you can already view the Earth 2 demo i belive

[sacred seal]

Well it seems like it takes a heck of a lot of processing power to run it, betting it will be awhile before places start picking it up for general weather forcasting

[jade scaffold]

64 gpus

its one stack of racks

[sacred seal]

I thought they said it was more then that?

[jade scaffold]

most big news companies can afford that

[jade scaffold]

with old GPUs

with the new ones its less

[sacred seal]

"This one is not run on 64 GPUs, this was run in the past on a lot more GPUs"

[jade scaffold]

i mean B200 may or may not have 3x the number of cuda cores that the H100 has

they've been working on the moddel for a really long time

what you saw in the video was a pre recording of Earth 2

where as now it can be run real time aparently according to jenson

[sacred seal]

Ah, so that is what he ment by that

[jade scaffold]

B200 is insanely fast i really hope the dual chiplet makes its way into a consumer gpu this gen

i want a 44,000-52,000 core titan card this gen

that would be cool

if not the 22000-24000 core 5090 will be more than good enough

[sacred seal]

I wonder how long it takes to run one of those sims. With the service I pay for their "high performance" model is updated about once every two hours

But it only looks ahead 48 hours

[jade scaffold]

Real time for the 2km accuracy one jenson talked about in the keynote so if you can view it real time then that would be awesome its good for predicting if a storm is heading your way and 2km resolution is kinda amazing for seeing how much damage big storms might do

like you can predict the estimated cost of a hurricane and where it will go alot more accuratly

i think its only another 2 generations till we are going to see a 100,000 CUDA core GPU which will also be crazy

[sacred seal]

Real time is kind of meaningless in this context. If it can only simulate real time (it simulates the weather as its happening) its kind of useless

Needs to be faster then real time

[jade scaffold]

yea it will predict into the future thats a brain fart on my part

[sacred seal]

How long does it need to look ahead 1 hour

[jade scaffold]

they managed to predict an entire path of a hurricane though

not sure how long that took

but aparently it managed to do it when using old data and to a greater accuracy than what was done traditionally at the time

[sacred seal]

Yea, like they say extreme weather event 3 weeks in advance, but does not say how long it takes to predict that.

[jade scaffold]

i mean they kinda just pop up

you dont have all that much warning before a storm becomes a hurricane

so it'd have to be pretty fast

[sacred seal]

Well if they say its 3 weeks in advance, it could take a week to compute, so 4 weeks total time type deal

Would still be impressive, 14 day forcasts are rarely accurate

[jade scaffold]

its 1000x faster at predicting weather than traditional weather techniques according to NVidia

it can simaltaniously produce several different outcomes for a storm and sort them by most likely and least likely

Nvidia Might directly run Earth 2 so you might be able to pull directly from NVidia if they let a normal user do that

[sacred seal]

Which knowing how AI works that is kind of a given

Most NN powered stuff spits out a bunch of ranked possibilities

[jade scaffold]

yea which just ends up working in favour of weather prediction because weather is a constantly changing thing

[sacred seal]

Like this is increadably cool and all, but as a consumer who actually pays money for these kinds of services its a bit frustrating how vauge they are.

[jade scaffold]

even if you can allways see accuratly 2 days into the future thats a massive acomplishment given the accuracy vs current techniques is genuinely nearly 100x higher

[sacred seal]

Hell, I would settle for 12 hours of accurate weather forcasting

[jade scaffold]

also being able to physically see where the weathers moving on a little visual would be pretty cool

oh great they are planning on using Earth 2 to actually simulate to even smaller scales

like building scale wind simulations

idea is city architects can see how placing buildings in certain places effects how wind will move though cities to avoid unintended side effects

[sacred seal]

Dont think the, what was it 1k res will be accurate enough to deal with that

[jade scaffold]

yea that wont be it will be a slightly seperate thing

still part of Earth 2

but you select a city or model of a city you have throw it in and then you can simulate how different weather conditions might interact with the city

Im really excited for the Next gen Jetsons too

blackwell Based Jetsons are gonna be so insanely fast

[sacred seal]

I have a good degree of familiarity with Gliders, you would need like a 10m resolution to get usable wind data out of a city scape

[jade scaffold]

if its possible to get the 1.25km on a global scale simulating somthing only 50km wide is probably not that hard

[sacred seal]

Well you have to map it accurately first

[jade scaffold]

not somthing thats going to be comming to consumers definatly a proper work kind of thing

[jade scaffold]

thats already done

[sacred seal]

And 1.2 5km is not that impressive, the HRRR model already does 3k, so basically we are only quadrupaling the res vs what we already have

[jade scaffold]

and it can only do 3km out to an hour

[sacred seal]

No, does it out to 24

48*

[jade scaffold]

which makes it shockingly useless against hurrcains

[sacred seal]

HRRR is the bottom one

It updates once an hour

Meaning it can process 48 that in less then that

[jade scaffold]

HRRR can do 1 Hour accuratly everything after that is a pretty blind guess

[sacred seal]

I would not say that it can do one hour accurately, but it tends to be more accurate then the other models on offer out to the 48

[jade scaffold]

its also working with much less data i think its 1 scan every 15 min for an hour

[sacred seal]

Also HRRR only runs in the USA

Not the entire earth

[jade scaffold]

and at a sub a quarter the resolution

[sacred seal]

Yea, so earth 2 is potentially a huge step up. Just unclear as to how much of a step up it is

And how accurate it is

How is it I can look at 5 different forcasts less then 24 hours into the future and predictions in thee different directions

[jade scaffold]

1.25KM at substantually higher speeds
they managed to predict a hurricane with pretty much perfect accuracy in a simulated test 3 weeks in advance and i belive that was when it was only trained on Tiwan that was before they trained it globally once Blackwell is in Full production i Expect to Start Seeing Earth 2 Pop up all over the show would be sick for MS Flight sim accurate weather in areas you're flying over thats pretty cool

im presuming it'll eventually be used to predict the oceans behaviour too for seems kinda usefull for boats

they are already using some form of model for water based projects aparently some early adopters do have access to the city level one

[sacred seal]

Looked it up, the second most accurate model that I use is ECMWF, which is a 9km model looking out 10 days. Given the difference in accuracy between ECMWF and HRRR, (I have my own weather monitor that I compare against), the 4x increase in res may not be as sinificant as I first thought (HRRR is 9x more detailed then ECMWF)

[jade scaffold]

though 10 days out at a lower res which is why its accurate to general areas and for so far out

9km is alot less compute than 3km and alot alot alot less than 1.25km

HRRR will be more accurate within an area within a shorter time frame
ECMWF will be more accurate at a longer time frame but less area specific
NVidias Digital Twin will be more accurate out to a longer time and at a higher res

[sacred seal]

Yea, I know. But I am regularly comparing the two against what actually happens. I would say that HRRR is closer to the actual outcome within 24 hour window only about 75% of the time, and that is with a 9x res increase

[jade scaffold]

also its not a Quartar resolution

1.25x1.25km tiles is like not far of a 6th of a 3kmx3km tile

9x9km is quite literally 9x bigger than 3x3km 1.25km if my math is right would be over 50x the accuracy of 9x9 in terms of area

[sacred seal]

I think we are talking past eachother here

9km to 3km is a 9x difference. My point is comparing the two models HRRR is only more accurate 75% of the time

And that is with a 9x res difference

I would expect the difference between ECMWF and HRRR to be larger then HRRR and earth 2

[jade scaffold]

if Earth 2 even gets close to accurate within the 3 weeks they showed off for hurricane prediction that makes it hugely more accurate than either ECMWF or HRRR which is what i find impressive that increased tile density also helps with letting you know if a cloud is gonna pass over you or piss it down on you

[sacred seal]

My claims are purely based on resolution. They may have some secret sauce that lets them leep frog the current models, but they are not giving us enough numbers to really compare

[jade scaffold]

we need more time frame data

still a nearly 6x increase over HRRR even if its only in the same time frame would be nice

[sacred seal]

Well what I would kill to have is the CI95 range

How far off the mark is its predictions for a given time range

[cinder lagoon]

Hey, anybody know of a relatively cheap 4.1 channel USB DAC?
Google is basically useless and "copilot" is currently targeting the ground sooo...

I specifically want something for my car. My raspberry pi only has 2 channel output but I want front + rear control.
My plan is to hook it up to a 4 channel car amp from Sony but that one doesn't include a DAC (because why would it?)

What are good solutions here?

[sacred seal]

4.1 is a fairly rare standard, going to be difficult to find a dac for that

[cinder lagoon]

Well it can always be 5.1 and leaving out the center channel

[sacred seal]

Might be able to make it work with a 7.1 and only plug in the desired devices?

[cinder lagoon]

https://www.reichelt.de/delock-usb-sound-box-7-1-delock-61803-p261427.html
this seems pretty good?

[cinder lagoon]

The 4 in 4.1 is the minimum spec lol

[sacred seal]

Depens on how the audio is bieng parsed, no? If you send 7.1 mastered audio to a 7.1 box, you may have some fun issues if its not fully plugged it

[cinder lagoon]

The audio is mostly gonna be just stereo but I wanna have software controls for audio positioning

https://www.reichelt.de/soundkarte-extern-spdif-7-1-usb-typ-b-st-icusbaudio7d-p190830.html
lol found the same thing but more expensive

[sacred seal]

If you send stereo audio to a stereo dac with only one speaker plugged in, you will just loose half the audio

If you are sending sterio audio to a 7.1 system I assume it would be smart enough to get it to work with 4.1

[cinder lagoon]

Well duh, my source is mostly stereo but the rpi will do magic to do stereo centering

So it's gonna output a 4.0 signal but I might wanna have a separate sub output

How are you finding these? My search engines just spit out garbo

[sacred seal]

I am searching amazon.de directly

[cinder lagoon]

😳

Daring

[sacred seal]

I cant read anything (because its in german), but it at least lets me check for things that I know for a fact are avaliable in germany

[cinder lagoon]

Ok true haha

The one you sent has probably the exact same pcb like this DELOCK one and I just found a page on berrybase (rpi supplier) that it's confirmed working in raspbian

[sacred seal]

Nice thing about amazon is if it doesn't work, you just return it (I presume that return policy in germany is the same)

[cinder lagoon]

Yup

Great, thanks for the help!
Didn't think to look on amazon cuz their listings are mostly full of ads and sponsors and thereby useless

[sacred seal]

And that's fair. I tried finding this stuff on the canadian version of Amazon and it was not great

[cinder lagoon]

Hmmm... so does the optional sub get connected to Center/BASS or Back (C Sub)?

[sacred seal]

I think they may have just screwed up the lines

Does not make sense that rear is connected to center/ bass

[cinder lagoon]

Ohh that would make much more sense now that you say it

wonder what the C in C/SUB stands for

[sacred seal]

Center/sub

[cinder lagoon]

sarcasm

[sacred seal]

Ah, missed that

My bad

[cinder lagoon]

But thanks xD

Thank you very much!

[sacred seal]

Hope it works out for you

[cinder lagoon]

Been already lookin for like 2 hours

[sacred seal]

Sounds like a fun little upgrade

[cinder lagoon]

Hell yeah

Including the rPi openDash build, absolutely.
2003 car with all the digital updates it would need. OPEN SOURCE

[sacred seal]

Sounds like my car

[cinder lagoon]

Kinda amazing what exists out there

You're also running openDash?

[sacred seal]

Minus the upgrades

No, I also drive a 2003

[cinder lagoon]

Ahhh okay lol

I wanna put up a repo containing everything i've done for that project.
The openDash repo is an android auto head unit emulator and it even works wirelessly (sometimes lol)
with that, an appropriate screen and a new console frame that thing will be a blast as a daily car

[sacred seal]

They dont make em like they used to

[cerulean helm]

Hmm, I can pick up a LG Ultragear 27GR95QE QD Oled open box for $750. Thats tempting.

[balmy flicker]

Does any one know if Nvidia extra set of settings is still a thing

[jade scaffold]

the what

if you mean the Nvidia control pannel then yea

thats still a thing

alot of its settings are now in the new NVidia app

[flat vale]

What windows version (if you use Windows) does everyone have?

[sacred seal]

I think is about a 60 40 split here between 10 and 11

[flat vale]

What will the Windows 10 users do after october 12 2025?

[sonic meadow]

probably the same thing the 7 users did after whatever its date was, nothing

[flat vale]

Yeah some people still use windows 7

If i can get my old computer with windows 10 on it working again I am thinking of going back to it, cause i wont need a emulator for a game I like to play

[cerulean helm]

I switched to Win 11 when I updated to a 13700k for the needed Windows Schedular. And haven't felt the need to go back to 10.

[flat vale]

A game I like to play Dragon Raja (A mobile game with a pc version) wont change local version to newest version for me on windows 11

[frozen igloo]

My computer force upgraded itself when I was out of town though ive experienced minimal issues, it just feels like a reskin rather than something more serious

[flat vale]

I only been using Windows 10 since like 2018-2019 until like the 25th to 27 when I went to change thermal paste and found out we didn't have any so I used toothpaste and believe the motherboard is fried. I only started using Windows 11 on Friday the 12th and so far I hate it since i can't play a game without a emulator take uses so much memory and cpu.

[cerulean helm]

I'm sorry, but wtf? Toothpaste as thermal paste?

[sonic meadow]

works pretty well as a thermal compound in the short term. many things do in fact, the issues is that they dry up and become shit

heck, some things perform on par with or better than some thermal compounds... while still wet

[flat vale]

Yeah when I seen we didn't have any thermal paste I should have left my computer alone and used a Laptop to let people know, But I didn't cause I have used windows XP computers and windows 7 computers for years and never changed thermal paste, so it was the second time we had done thermal paste change on a computer (we changed it on the same computer when I spilt water on my motherboard back in like 2020-2021).

[jade scaffold]

I Use windows server

its way more memory efficient than 10 or 11 and you can have the GUI from 10 or 11 and still get the advantages of the new core scheduler

[mossy gull]

So with latest Windows Server I can make it look like W10 with W10 full screen start?

[jade scaffold]

maybe?

[mossy gull]

Is that a yes or no?
Because W10 goes EoL soon and I hate the menu from W11

[jade scaffold]

I don't know

[mossy gull]

Sad....

[jade scaffold]

I don't use full screen start

Hell I hardly use start

Just get Start 11 off steam if the windows UI bothers you that much

[mossy gull]

Start 11 sadly has no full screen start🥲

[jade scaffold]

you can make it take up the entire screen

turn rounded corners off have it grow to fit your screen

infact you dont even have to do that

theres a use full screen menu option

[mossy gull]

I prefer with big icons, these small icons are annoying. I sit 2 meters away from my display and these small Icons simply don't work.
I don't have my own JWSP just to see the small letters.

[jade scaffold]

everything is configurable

you can make thoes icons take up the entire screen if you really want

also keep in mind i runmy windows on really small text scale

cusomise the text fonts and everything

[mossy gull]

I still don't like W11 style, reason I love the tiles is because they can be huge and easily visible.
But these days everything has to be tiny

[jade scaffold]

wow you are just not getting this are you

what part of fully customisable do you not understand

[mossy gull]

Sorry, I am just annoyed with W11 menu styling.

[jade scaffold]

thats what start 11 is for works on W10 too

windows server desktop version might support the tile thing by default

i dont know

[mossy gull]

I may test this at some point.

[jade scaffold]

heres a real quick way to test

throw a virtual machine up

itll take 30 seconds

and you can just check

[mossy gull]

I have an Alienware with a keyboard bug, maybe I can test it directly on that machine and see if it does work on Windows Server as well

[surreal moss]

whistles innocently

[surreal moss]

Welp, the pots are fine. The board is fried

[timber barn]

what is that?

pedals?

I wonder if that is worth taking to a DYI local repair shop

looks so simple

[surreal moss]

CH Pro rudder pedals

I've had them for almost 9 years now. There's a problem where the Z axis is either off or on. I thought it was the potentiometer and swapped that out but I still have the issue. So something is wrong with the board

[sonic meadow]

Could be wires

[timber barn]

Or old soldering

[cinder lagoon]

Dang this Corsair RM850x gotta be really good 😳
Something just happened on the grid that cause my router to restart and my (touch) lamp to turn on (its on after disconnecting power) and my PC just continued playing youtube like nothing happened

THE LAMP JUST TURNED OFF FOR LIKE HALF A SECOND AND THE REST STAYED ON WTF

[flat vale]

I hate Windows 11

[cinder lagoon]

Which part of it?
Theres multiple you can reverse

[flat vale]

Anytime I am looking at any tab in any web browser that is not Edge the screen flashes, but when using a wed browser that is not Edge. And one of the games that I play wont work on windows 11 with its pc version so i need a emulator to play the mobile version.

When i have the emulator open i can't change volume at all

Going from windows 10 to 11 is like going from windows 7 to 8, when they have something good going they go and change how it looks

[cinder lagoon]

That seems wrong.
There should not be any flashing and you shouldn't need an emulator for something that ran on windows 10

[flat vale]

The game is Dragon Raja and when i try to play the pc version it wont change the local version to the newest version so i need a emulator

i have the 23H2 update for windows 11

[surreal moss]

Compatibility mode doesn’t help?

[cinder lagoon]

Ahh good call

It could also be that your install is corrupt. Did you upgrade or re-install?

[flat vale]

Windows 11 came on the computer I had to update it to 23H2 and then i downloaded the games install and still nothing

[flat vale]

Not sure but i can look

[flat vale]

Didn't fix it

[cinder lagoon]

Hmmm no idea then

[flat vale]

Same its really odd

hopefully the 24H2 and 25H2 versions will let it work

[cinder lagoon]

I would reinstall tbh but I do that on all PCs I get

[flat vale]

Its odd cause its the only game that does it so far

[sacred seal]

So I am not overly familiar with POE standards, I recently had one of these POE injector die
https://www.amazon.ca/Ubiquiti-Networks-NA-PoE-Adapter/dp/B07HDPGH4M/
Since I have two of those in the same location, I was thinking of getting this
https://www.amazon.ca/TP-Link-TL-SG1005P-Gigabit-Ethernet-Desktop/dp/B076HZFY3F
What's the odds that it's going to work?

[mossy gull]

Why not get a switch that has PoE

Then you don't need an injector

[sacred seal]

That's what I am asking. Will this TP link switch work in place of the injectors

I don't know the relevant specs for POE compadability

[mossy gull]

It should I think, I am not familiar xith TP-link

[sacred seal]

Well there is like 4 different standards of poe and within those a bunch of other conciderations, and I have no clue which is which

[mossy gull]

The differences are max power output pretty much, nothing else

[sacred seal]

OK, both seem to be poe+ so it should work then?

[surreal moss]

Yes. I have one in my home

[sacred seal]

Fantastic, thank you both for your advice.

[surreal moss]

Generally speaking POE just works. You’re going to find yourself in a pretty niche situation for it to not work

[sacred seal]

Well the first time I bought a replacement poe injector it did not work

[surreal moss]

That’s… very odd

I do tend to avoid the injectors, though

[sacred seal]

Though that was replacing a isp provided one

[surreal moss]

Comcast?

[sacred seal]

No, it was some local company

I live out in the country so I get my internet through dishes

About 6 years ago I decided to cut out the middle man and make my own mini wisp with some neibors. Its worked fairly well, but one of the POE injectors died

There are 5 houses in the network, with only one of them having two dishes, so the included injectors work pretty well

[mossy gull]

I only use them on very long distances

[sacred seal]

About 10 years ago I had a flood in my basement and it killed the injector for the ISPs dish. As the ISP would take several days to get me a replacement, I bought one off of amazon, but for whatever reason it did not work

[surreal moss]

That makes more sense now

[mossy gull]

Maybe the injector wasn't strong enough, or they encrypted their devices

[sacred seal]

Yeah, who knows, but that is why I was asking if it would be compatable.

You don't know what you don't know

[surreal moss]

Totally fair. Although if you’re going to a dish like you described I’m now less confident in my recommendation

[sacred seal]

Eh, its amazon, if it doesn't work I will return it

I happened to have a spare injector so there is no urgency, I am just thining getting a cheap switch would be a better alterntive in this case

I have two injectors and a switch there currently, be nice if I could have it as one unit and then keep the current injectos as a spare

[cinder lagoon]

Just to chime in after the fact: there's multiple POE standards, each being capable of a higher power than the one before. Iirc they were labelled POE+ etc.
With POE injectors you need to be careful because there are some cheaper ones that just dump power on the relevant pins and there are some that follow the standard and do a handshake before applying power.
This is important in case you connect a non-POE device because that would get fried without a handshake.
Also important in case there are some A/B pinout cables somewhere

[oak reef]

The best days are when you get new toys tools to play with

[sacred seal]

Why is it so hard to shop for laptops? I want something with a 780m because it offers good enough performance without having dgpu power draw levels, but good luck trying to figure out which processors have it

[cinder lagoon]

Yeah

All the filters are always "ryzen 5, ryzen 7" and "radeon graphics"

I think there's a very limited amount of CPUs with that chip so you can probably put the CPU name into the searchbar and get pretty good results

[flat vale]

Well My windows 10 computer is fed up

I got a "new" motherboard and cpu for it and I got it to start up but it wouldn't read the SSD and HDD and ran a bios diagnostics it has a error for the Front USB port cable and to unplug it, so i did and now it won't even turn on

[cinder lagoon]

I'm really not sure what exactly you're doing to your PC to get such specific and odd problems but good luck fixing that lol

You may try reseating the CPU and checking for bent pins.
And if it's used hardware (seems like it is) don't forget to download a BIOS update and wipe the settings.

[flat vale]

myself and my father had the SSD and HDD unplugged to see if the Power supply was dying, it came on so I plugged them back in and it wouldn't read from them so I did a bios diagnostics and it said error with the USB front cable. So I turned it off and unplugged it I turned it back on then it went right back off.

[mossy gull]

When an SSD or HDD is completely fucked, it won't read from it.

And only 1 has to be broken to stop POST.

[flat vale]

Really dang and the SSD has the system on it

[mossy gull]

Have you tried with the SSD alone?

[flat vale]

No I didn't

I don't really want to touch it again but i will try that late on today

[mossy gull]

Also, with a new motherboard you may have to reinstall Windows to make it work properly.
Also, I don't know what SSD you have but you can buy adapters for it so another system can read it.

[flat vale]

I didn't the last time I put a new Motherboard in which is why i found it odd when nothing was woking today

Its some Samsung SSD

[mossy gull]

What was the old and what was the new CPU?

[flat vale]

same Motherboard as the one that was in it and same CPU the Motherboard is a Dell Optiplex 7010/9010 Mother Board and the CPU is a i5-3470

all old used parts so I think I am just getting unlucky

[mossy gull]

Maybe it's time to replace the storage

[flat vale]

the power supply is a GP-550 80 PLUS Bronze and its the same power supply when i changed the motherboard the first time cause of water

[mossy gull]

If the PSU touched water inside of it while it was being powered, it can kill the entire system, or parts of it

[flat vale]

Yeah it was like back in 2019-2020 I think when I had to change the Motherboard but I never changed the psu

and everything worked fine up until I went to change Thermal paste only to find out after I had remove the stuff that was on it that we didn't have any, SO i looked up online to see what i could use and well Toothpaste...

I should have just set my computer aside and waited for new thermal paste

[mossy gull]

Toothpaste only work temporarily, and only suitable for light tasks.
Also you need to make sure toothpaste doesn't have conductive materials inside of it.

[flat vale]

Yeah and I didn't know that and on march 31th I got home went to start up my pc and nothing

it tried and went straight off

[mossy gull]

Without drives, can you get into the BIOS?

[flat vale]

Yeah we had the f2 menu up twice cause the drivers wouldn't boot up, so I did f5 and ran bios diagnostics which told me something was wrong with the front slot usb cable. So i unplugged it and bam no more power

[mossy gull]

Is something in the front USB panel?

[flat vale]

Nope

[mossy gull]

Then something is probably wrong with that panel, maybe it got fried by something else.
But if you can't get into Windows then something is wrong with your bootloader or storage device.
And that front panel, I wouldn't connect it again if it shorts the motherboard.

[flat vale]

Yeah but thats if i can ever get it working again

I am not the best when is comes to computers like I know how to use them but fixing them is another issue.

[mossy gull]

I am not good at fixing pre-build, and especially not older ones 😅
So we have something in common.

[flat vale]

Yeah and I don't really like Windows 11, but I find it odd that this game i played on Windows 10 the company don't support windows 11

[mossy gull]

Windows 11 doesn't natively support your system, that could be 1 of the issues as well.

[flat vale]

No I have a new pc that came with Windows 11

800 dollars for it

[mossy gull]

Oh, well I don't know much about W11 because I am still stuck on W10

[flat vale]

Yeah like 70% of people who are still on windows 10

like dang 70% of computers are still 10s and over a billion computers have windows

[mossy gull]

For me it's for compatibility and because I sit 1.5 meter away from my display and the big massive tiles are easy to see.

[flat vale]

Yeah my computer with Windows 10 couldn't upgrade as well and I lay in my bed on my computer

Windows 10 is easier to use then 11 from what i can tell

[mossy gull]

Windows 11 has nice things, but too many stuff is made for people who sit a normal distance away from their display 😅

[flat vale]

Windows 11 is for the programmer or some IT guys

some things are good some are bad

[sonic meadow]

Neither of those want it

[mossy gull]

I would use W11 if the start wasn't so hideous and if the taskbar could be moved to the left natively

[flat vale]

I see some comments in Microsoft forums saying they like it, but yeah Microsoft pushed using Ai way to hard and made changes that is creating a lot of e-waste for a company that wants to go green

like this?

I find the buttons to small

[mossy gull]

Taskbar at the bottom is nice when you have monitors side-by-side or only 1 monitor.
I have 2 stacked, which means when test driving I got a program stuck under the taskbar.

That's why I have the taskbar on the side

[flat vale]

Yeah you meant like move the whole taskbar

[mossy gull]

Yes, on my system I have it on the left.
Because I have 2 UltraWides stacked.

[flat vale]

Oh nice

[mossy gull]

On another system I did a more wack thing and that's on the bottom display it's on the bottom and on the top display it's on the top.

[flat vale]

I just have one Monitor

[mossy gull]

Which Windows 11 is perfect for

[flat vale]

Same monitor I had for 10 as well

Heck it could even me the same monitor i had for windows XP so many years ago

[mossy gull]

Windows XP, man I hated thay OS

[flat vale]

lol we loved it hates VIsta and ME/2000

[mossy gull]

Windows Vista was slow, but it was stable

ME was a clusterfuck

[flat vale]

We like XP and 7 if you don't include 95 and 98

[mossy gull]

W7 was really unstable for me, on 2 systems

[flat vale]

Odd we never has a problem with it but then again we got to windows 7 like in 2010 to 2011

[mossy gull]

The most unstable experience was on 1 of the 1st systems that supported an external GPU😃

[flat vale]

Yeah Some people Windows work great for and for some well not so great

[mossy gull]

Funny enough, once Windows 8 came and they started acting awesome like they're the 1st with external GPUs, I was there, using a laptop, with an external GPU, way before anyone ever got theirs

[flat vale]

lol

[mossy gull]

I remember the time when iPhone got wireless charging, the iPhone fans started acting like they were the 1st with magnetic charging.

And I took out my Palm Pre 3 phone and showed them I could charge, by magnets, decades before they could.

[flat vale]

lol Don't magnets break phones

[mossy gull]

Nah, haven't for ±30 years.

I even remember the time Android users were acting like they were the 1st when their phones could multi-task, once again, me with my Pre 3, multitasking way before they did.

I love being ahead for no fucking reason.

Now I am pretty much behind almost everything

[jade scaffold]

Magnets breaking computer stuff is kinda a myth

[sonic meadow]

It was basically an issue for two things:

• magnetic storage. Floppy discs, tapes, and hard drives
• crt monitors

[jade scaffold]

It's not even an issue for hardrives really

You need some MRI shit to corrupt harddrive data and at that point the magnets so strong the drives being physically destroyed

[mossy gull]

Or just an electro magnet

It doesn't even happen to bank cards anymore

[jade scaffold]

A really really big one

[jade scaffold]

Nope

Long since passed the days of magnets having any measurable effect on electronics

[mossy gull]

https://youtu.be/g0amdIcZt5I

You need that magnet to disrupt electronics

[sonic meadow]

"Was" is past tense :p

[jade scaffold]

Were older hardrives that effected by magnets?

[mossy gull]

Nope

[sonic meadow]

Older ones could be, but it was still rare

The small magnetics tech wasn't as good

Tapes and floppies were the bigger issue though

[mossy gull]

I use a floppy to unlock my door😅

Or Diskette as their original name is

[cinder lagoon]

not sure if this is a communication problem but to me this sounds like complete bs diagnostic - i.E. I'm pretty sure the hardware is actually fine, just misconfigured.

[cinder lagoon]

in other news: I actually got this low cost pcie switch for my Pi and now I want to plug things in.
Experiences with products like these?
https://www.amazon.de/dp/B09SGYJDP2/
https://www.amazon.de/dp/B08M5VC374/
I think this is the lowest cost solution to pcie expansion.
Its only PCIe gen2 x1 so 500MB/s

Also not sure what to plug into that thing, ideas for usage in a car infotainment system?
My plans this far are:

• USB 3.0 controller (for thumbdrives (+ android Auto port) in the center console)
• NVMe drive for boot and dashcam recording? I could put recording on the USB and just boot of the eMMC - its faster then the nvme linked via USB 2.0
• maybe an old AMD GPU as a graphics accelerator - the pi4 is fine but sometimes things feel sluggish. gpu compatibility might be limited too

[flat vale]

I still haven't tried my computer

[flat vale]

@mossy gull I just tried the computer With everything but the Motherboard unplugged (I had left the Memory cards in though), and it came on then went of like it normally does when you plug the power in so i push the power button and it came on but went back off and stayed off.

Who's seen the minisfourm V3?

Looks really cool

I kinda want it but it's a tad expensive

Only 4 hours of battery life browsing minisfourm what the hell

You have a low power mobile Ryzen in a 14 inch tablet and your battery is being outlasted by the steam deck half of that things volume should be battery

[flat vale]

That is so bad

[sacred seal]

Yea, I just got this which is comprable spec wise https://www.lenovo.com/ca/en/p/laptops/ideapad/ideapad-2-in-1-series/ideapad-5-2-in-1-gen-9-(16-inch-amd)/83ds0000us

THat's a good 400usd savings

Granted the minisforum v3 has 16gbs more ram

And a nicer screen by the looks of things

[mossy gull]

That's sadly rather normal under Windows.

[flat vale]

How much was it for you?

[sacred seal]

I got it for 924 cad after tax

[flat vale]

Ah fellow Canadian

So talking aboot windows why was Windows 11 marketing so bad for?

like I never heard about it or seen anything about it until my computer died

[jade scaffold]

No it's not

That's minisform having loads of space for battery and wasting the entirety of it on dumb shit

You could make the PCB of that computer the size of a Epyc CPU and use the rest for battery and just have ribbon cables to your Io

And then get a 70-80wh battery easy which would last 2-3 hours worth of playing games

[mossy gull]

I never been able to do more than 4 hours on battery with webbrowsing.

[jade scaffold]

Probably more if you disable the 4 pointless extra cores you get

[jade scaffold]

I had a laptop from 7 years ago able to do 11 hours easy

And it was thinner than that tablet and less wide when closed

This is just a case of wank battery optimisation and poor space utilisation

[mossy gull]

Does the Minisforum have an Intel CPU?
Because they're lately very inefficient

[jade scaffold]

My laptop from 7 years ago was intel

How can the minis form V3 not do sub 5w web browsing

Pretty much every CPU I've EVER had could do that

Also sub 1.5 gaming on a I GPU really?

Even most laptops with a d GPU can manage that

My epyc can do that

[mossy gull]

Intel CPUs, since they got the E-cores, have been very inefficient, not because the CPU, just to keep the damn thing cool.

Also, Minisforum always been bad with their systems, especially their cooling

[jade scaffold]

Their cooling is fine

It's small form factor cooling tiny things is hard

And Intel's old p/e core design is crap

The new design is much better

The issue on the minisform tablet isn't cooling

It's just inefficient usage of internal volume

[sonic meadow]

the screen on it is going to be a massive power hog. 2560x1600@165hz at 14" is.. hefty

a 50Wh battery seems otherwise pretty reasonably

though with the cpu limited as high as 28w... yeah that is portable not on-the-go work

[jade scaffold]

It's not limited to 28

You can up it to the full 58 in the bios

[jade scaffold]

Why the hell does the soc draw 12 Browing the web

[sonic meadow]

high resolution high refreshrate screen would be my guess

[jade scaffold]

Then that's a bug

Also the 4 hours of web browsing figure comes with the monitor locked at 50% brightness at 60hz

[sonic meadow]

badly configured power profile maybe 🤷

[jade scaffold]

And I've seen much higher Res screens last much longer doing web browsing I'm really not sure what the hell is going on with the V3 the power config has to be totally ass to get those kinda numbers out of that kinda soc

Unless the ai hardware in the 8840u takes the place of some of the encoders the otherwise identical 7740U has?

[dull garnet]

Have this audio problem connect and reconnect with my blackshark v2

One person said my usb hub is overwhelmed

And have fan controller but that Pacific port for that

[jade scaffold]

Is it causing all your usb to drop out?

Or a number of them at a time

If not probs not a usb port problem

[dull garnet]

Just my just my headset

I had the wired v1 one to

G560 had that problem when the rgb was but think get fix

But am be wrong

B760 AORUS MASTER DDR4

Is motherboard I have

[jade scaffold]

Hm are you using the back ports in the mobo or the ports on the case?

[dull garnet]

Back

Fan controller is plug in on board

[jade scaffold]

Are you able to use a none usb connection with it

Some black sharks can be used without usb too

[dull garnet]

All of them

Can use

Some problem

[jade scaffold]

Can you plug them into like a normal audio port tho?

[dull garnet]

Yes and bin use it as workaround

Work fine to

[jade scaffold]

If so try that see if you get sound if you don't get sound you might have to reinstall audio drivers possibly? should be able to find them on your mobos website

[dull garnet]

K

Someone said that usb controller was overwhelmed

On Sc Spectrum

I get sound disconnected than reconnect

And it's random

[jade scaffold]

Usually if the usb controller is overwhelmed it'll knock out all of the usb at once

[dull garnet]

K

Would raser and logtech cause a conflict

I have g560 speakers

And just my audio and just my blackshark that do that

I bin use my wired version on jack and work fine no problem

[jade scaffold]

Not typically

It could literally just be the usb part of the razer's dying

My friends have had that happen once or twice with some older razer headsets

[dull garnet]

The blackshark v2 brand new

[jade scaffold]

Got a different pc you can test on?

[dull garnet]

No

[jade scaffold]

No computers anywhere atall you can test

[dull garnet]

My sister as pc and dad laptop

Not ask them do that

[jade scaffold]

See if you can find a driver for the headset

Maybe it's driver just broke or something

[dull garnet]

Update just recently

[jade scaffold]

Worth trying to install it again

May have corrupted

Or possibly the new update was the issue maybe reverting to the old update could fix it?

[dull garnet]

Think may be dongle and do not now reset that

Take a couple of tries to get the dongle updated because it kept stopping when I got it but also did this with the wired version of it the V1 version

Yeah but I will find razors drivers for it even though my computer says Microsoft compatible driver for my audio devices

But my headset are have worse of it

Luckily the Jack works fine

Happens usually when I have Discord browsers and playing a game all the same time

And have quadcast mic but that has no problem at all

I have i7 130000k
32gb ram
So no headroom problem

Have one newest cpu out there

[jade scaffold]

Yea CPU won't be the issue

Issues probably with the headsets usb itself

Hard to confirm that though unless you can find a pc to test if it works on

[flat vale]

Sounds like the USB cable on the Headset

In some fun tech news intel have completed assembly of the first high na lithography machine

This kinda machine in theory gives intel a node size advantage over tsmc and samsung

No one else had bought one yet because lithography machines cost a fair bit

Theoretically capable of a 2.9x density uplift

The machine does still need to achieve first light and be calibrated

Which is expected to all be finished by the end of 2024

AMD might release a laptop APU with 16 desktop CPU cores and an iGPU the strength of the RX 6700XT.
Which in some games beat the 4060 Ti
https://www.pcgamer.com/hardware/amds-new-uber-gaming-laptop-apu-rumoured-to-use-chiplet-design-and-16-full-desktop-spec-cpu-cores/

[tulip valve]

Ah the 40CU with RDNA 3.5 we been waiting on.

I want it.

[sacred seal]

There current offering with just 8 cut down cores and a 780m is a 45 watt part, there is no way they are more then doubling the performance with the same power budget.

I would expect a 100 watt chip minimum, and with that much power draw it kind of fails as a laptop

[tulip valve]

My Screenshot answers that lol. its 45w to 175w

[sacred seal]

What I am saying is anyone who thinks this can even touch 45 watts has no clue what they are talking about

We have never seen a more then 100% power efficiency increase over a single generation before

The 8700g which has half the cores has a tdp of 65 watts.

[tulip valve]

TDP does not mean it'll ALWAYS Be using it.

[sacred seal]

True, but it also does not mean it is the maximum power draw of the chip ither

[tulip valve]

Like, the Aerith APU has a 15W TDP in the Steam Deck.

But I can sure as hell bring it down to 3w

No one said it was the max

No one is expecting max performance at 45w.

I don't get where you're getting that from at all.

[sacred seal]

Doing some further reading, at idle the 8700g seems to draw between 40 and 60 watts. You really think they can double the core count and triple the GPU with 5 watts?

[tulip valve]

Do you have any idea how power usage works?

[sacred seal]

Yea, I do

[tulip valve]

Clearly not

The 7840u with the 780m and 8 cores can go down to under 10w

[sacred seal]

Uhh, not within spec it cant

[tulip valve]

What do you mean by within spec???

[sacred seal]

It has a minimum and maximum configurable tdp

[tulip valve]

and its under 10w

[sacred seal]

Wait, that may of been a different chip. Officially its a 28 watt part

[tulip valve]

Look at the various handhelds with the 7840u

and you can lock the TDP, just like with anything.

People have locked desktop components at lower wattages, its not hard. They perform worse than if they weren't limited power wise. BUT THATS TO BE EXPECTED.

[sacred seal]

Its been a long time since I have looked at undervolting, but things tend to get unstable if you push too low

[tulip valve]

Like, 45w is easy. It won't be peak performance. Probably a lot of the CU's would be disabled. which is exactly what current laptops do when power limited.

If you aren't playing a game, your laptop can be told "hey don't use that 120w GPU, the IGPU is fine"

[sacred seal]

You have any references for AMD disabling CUs? I have never heard that to be a thing

[tulip valve]

I said they could do that. Not that they do.

[sacred seal]

Sorry, misread then

[tulip valve]

The power usage on this will be fine. Comparable to regular gaming laptops. The question is if the performance will be there.

[sacred seal]

These are supposed to be full fat desktop cores, and a beefy GPU to boot. Even at idle power, 45 watts seems quite unreasonable.

[tulip valve]

AMD's cores are all the same asides from the little cores.

[sacred seal]

No, laptop cores are cut down somewhat

L3 cache

[tulip valve]

The L3 cache isn't in the core. The CCX itself is exactly the same

[sacred seal]

Still contributes to power draw. The artical makes a point to say that they will be using desktop cores, only reasonable to assume that includes the cache

[tulip valve]

Thats true it does say that.

[sacred seal]

Also for this chip L3 is on the CCDs

[tulip valve]

Thats fairly new for them.

However I think 45w for min usage iirc if they have gotten better at their scheduling.

The 8840u and the 7840u are functionally the same, but the 8840u is much better at lower wattages because of NPU. Which you can see on that diagram at a better rate than the 16 TOPs for the 8840u.

[frozen igloo]

My replacement hinge on my m40x has already failed, I plan on getting another pair of headphones and making the m40x my backup rather than my primary. What do you recommend? I'm thinking about getting dt770

[sacred seal]

I have only heard good things about the 770s

45 watts still seems like a strech. With full desktop cores we are comparing to the 8700g moreso then the 8840u

[frozen igloo]

I’m primarily looking for good sounding durable headphones, ive had the m40x for around two years and just started having issues

[sacred seal]

Yea, I have had two pairs of m40x's fail on me. They sound fantastic for the price, but the build quality is just not there

[tulip valve]

8700G has the same NPU as the 8840u.

The new one is better still

[mossy gull]

The Ryzen 5 8500G I think it is, those cores can go into a laptop CPU

[jade scaffold]

it almost allways is

desktop and laptop cores are the same as well

theres the Zen 4C cores and later will be Zen 5C cores which are just the standard zen cores but missing half of their L2 Cache meaning they can be packed far more densly this obviously comes at a substantial clock speed downgrade

Zen 4C cores max out at like 3.1-3.2GHZ their clock speed is so low the 128 core epyc will hit the same all core speeds that the Ryzen desktop part will on its single core boost speeds it seems 3.1GHZ is arround the hard limit for them Architectual improvements next gen could bring some Clock speed increases and ipc increases to the Zen 5C cores which should hopefully put them between the level of ryzen 3000 and ryzen 5000 but we shall see

Personally i think the Zen5C cores would be perfect for a laptop APU

APUs are slow af like the 780m stuggles to hit 1060 6gb levels of performance theres no need for a full fat zen 4 or zen 5 core you may as well use the C type cores which will give you plenty of cpu performance

[mossy gull]

The C cores are already enough for majority of gamers.

[jade scaffold]

honestly for anything upto about 1080ti levels of performance the Zen 4C cores are more than enough they outperform in single thread the 7700k and because modern games make use of more cores now you can get 8 zen4C cores running full tilt at like 10w

the 8 core Zen 4C Epyc has a defualt TDP of 80w

it has the same IO Die my Epyc has

my Epycs IO Die running in the more efficient mode i have it in will do 80W

[mossy gull]

Even up to a 6800XT the Zen4C cores good enough.

[frozen igloo]

Would you buy a pair of used DT770 pro 250 ohm for $100, the guy seems willing to go a little lower though I'm still on the fence about it

[jade scaffold]

if your device can drive them

[frozen igloo]

I'm have a fulla e that should be able to run them without issue

[cinder lagoon]

Hey, a friend of mine is looking for a monitor mainly suitable for (semi-professional) photoshop work for around 200€ (germany)
I was able to pick out some displays that I would deem reasonably accurate at that pricepoint and worth their money. Opinions? Other recommendations?

• Lenovo Legion R27q-30 165Hz 1440p for 200€ (B-Stock, damaged/incomplete packaging)
• Lenovo L25e-40 75Hz 1080p for 100€ (B-Stock, damaged/incomplete packaging)

are those good picks?

The used market did not show many good results

Actually barely any at all

[mossy gull]

Maybe try to look for panels with 100% sRGB, preferably higher.

[cinder lagoon]

Both have that

Ohh wait 99%

99 % sRGB- and 90 % DCI-P3 coverage on the Legion

[mossy gull]

What about the MSI G27C4X

Which also has a 10-bit panel

[cinder lagoon]

Well, its more of a gaming display (1080p, 250Hz) but you're right, it DOES have a wider gamut. I've read that the Legion is also pretty precise tho.
I should probably mention this thing is going to be driven by a Radeon Laptop GPU from like 2022 or something
Afaik my friend values higher resolution more than the accuracy but thanks for the recomm, I will present it aswell!

[mossy gull]

The problem is and not many people know this.
But the more a monitor is used, the less accurate the colours become.
This is thanks to it slowly getting out of calibration and sometimes even pixel degradation, which yes, also happens on LCD

[cinder lagoon]

Good point, the B-stock may have been used up to two weeks but it most likely wasn't so It's gonna be fine

[mossy gull]

You don't know if the person who had it before has messed with the settings.
So that's also 1 thing to remember

i fucking hate Java

It cannot be understated how much I despise the pile of poorly developed shit that is java

i thought the same so i tried an old version of the 1.16.5 MC server I used previously with this very same install of java and got the same issue

did some bit of my java installation just decide to fukin dip on me or somthing

gonna run the installer and see if i can repair it

nope

Thoughts on the Audeze Maxwell?

[jade scaffold]

They are pretty cool

Very spensive tho

They are like the 2nd cheapest audeze headphones you can get

These are peak budget audiophile

[sonic meadow]

thats an interesting design

[jade scaffold]

Audeze planar magnetics for £110

[sonic meadow]

visually I mean

[jade scaffold]

Yea they are a lil odd looking

[sonic meadow]

needs some doodads coming out of the top and it could be a brain scanning/interface/etc tool from some '80-'00 scifi

[jade scaffold]

And the mic in them is total trash however it uses audeze planar magnetics for sound so they actually apparently sound phenomenal and they are about as cheap as planar magnetics come

Because Sony owns audeze now

Plz Sony don't kill audeze like you kill the rest

[sonic meadow]

at least sony has a legit audio side to them

[jade scaffold]

Sony have always been good at audio tbh if audeze does cease to be a thing their tech will certainly show up in Sony products

[sonic meadow]

Sony™️ Audeze™️ planar magnetic headphones

[jade scaffold]

If their elite gaming headset has planar magnetics what stops them from putting them in the next gen wh1000xm6 flagships

Which costs nearly 3x as much

[sonic meadow]

the issue I see more is... sony using the audeze branding for cheaper/non-hifi stuff

[jade scaffold]

Yea I think it'll be fine

I want another Sony XB1000 headphone

Just massive headphones with abhorrent amounts of bass

[sonic meadow]

I just want my audio techinicas to be able to charge while using them 😆

Duh, obviously. cpw.mods.modlauncher.SecureJarhandler is the class from forge that loads the discovered mod jars. Try reinstalling forge for the version you are trying to use. Also make sure you're using a supported java version! Google what java version minecraft 1.16.5 uses and use that one, others are bound to not work!

[cinder lagoon]

Also: these look like the airpodest ali-express-phones xD like barely hearable sound quality

[jade scaffold]

It was the java version already figured it out

Forge 1.16.5 doesn't support java 17 or up

[cinder lagoon]

Glad you could lol

[jade scaffold]

But wait there's more

Another mod in the pack required a newer version than forge supports

So the modpack just didn't work

Works in the client version tho no idea what the hells that's about

Java's one advantage over C# is meant to be compatibility

But java isn't even backwards compatible with itself

[cinder lagoon]

Then that mod wasn't for the mc version. Can't just mix and match
if you show me the error and the link to the file on cf I might be able to help

[jade scaffold]

It was

Given up on that modpack too much effort troubleshooting

[cinder lagoon]

Ohh it was premade?

I can offer you a working 1.18 technic+magic+QOL modpack

[jade scaffold]

Premade and modified a bit

It didn't have a server version which is usually fine

We just knock off the mods that cause issues usually

Threw together a new pack that works

Though server is chugging a bit could use with maybe preloading all chunks within 10k blocks of 00 me thinks

[jade scaffold]

nice

the APU in the Ally is still dogshit

but nice

AMD really need a specialised hand held gaming PC APU

Zen 5C APU AMD please i beg?

[mossy gull]

Fun fact: The Z1 Extreme is based on the 7840U.
They removed the NPU from the 7840U and called it the Z1 Extreme, this made the APU slower in the process.
The only handheld that has the 7840U or now the 8840U is the GPD Win4, which is both smaller and faster than the Ally.

And did support AFMF as soon it was introduced

[cerulean helm]

So, looks like AMD and MSI split up in the GPU department. So no official word that I can find but MSI has been completely scrubbed from Radeon 7000 series.

It also could explain why MSI went with Intel for the handheld Claw.

Wonder what happened.

[mossy gull]

MSI always made weird choices.
I have the feeling they ask for a lot of slag from companies and that's why they always been able to sell the newest shit for the lowest prices.

[cerulean helm]

Well, considering the silence from MSI and AMD, I think this was not a peaceful breakup so to speak. Like, MSI's entire lineup of AMD cards have been scrubbed, removed, and all existing stock is listed as discontinued.

I'm not fond of MSI, Ive had 3 bad gpus from them in a row and a damaged refurbished card that was sent to me by them. So I have no hard feelings if they got booted by AMD.

[mossy gull]

Could be that AMD ceased cooperation between them.
I personally always had a beef with their support of there was once again a broken product, so you will never see me recommend anything from them.

[jade scaffold]

No not really

The 7840u and 8840u are just poorly configured apu

They fail to match the steam deck apu unless run at a comedically high tdp

[mossy gull]

And yet in gaming they were better 😃

[jade scaffold]

Only at higher tdps

They are the most confoundingly ballenced things ever why does your mobile apu have 8 cores

[mossy gull]

8 cores are cooler than 4, and gives you a bit of a headroom in CPU heavy tasks

[jade scaffold]

4 full fat zen 4 cores would give you headroom

And let you maybe have any kind of power profile similarity to the steam deck apu

Also we are getting AM5 based epycs

Don't know what for

Seems kinda dumb imo but you do you amd

It's not like they can get that many more pcie lanes crammed in there? Maybe it's just for proper rdimm and CXL support

[mossy gull]

I prefer a real Threadripper where the slots are full 16x slots

[jade scaffold]

Welllll

Unless you get the pros the slots aren't full speed

Sure it's full 16x

But it's usually gen 4 for the others

[mossy gull]

Threadripper, 7 PCIe 4.0 16x, good enough for me😅
I only need 2 GPUs, not more

[sonic meadow]

you would rather they... didnt use their newer, faster, more efficient archicture?

[jade scaffold]

They already have the new architecture

My epycs zen 4

Why AM5 socket epyc tho

[sonic meadow]

ohhh, the socket was the important part of your statement
for small-server applications, like NAS, routers, most small business applications. that kind of thing

not every application needs fuckoff numbers of pcie lanes or memory channels

[jade scaffold]

Maybe?

But standard AM5 CPUs support ECC maybe not RDIMMs

[sonic meadow]

if its anything like am4 then motherboard support for ecc will be... iffy

since basically every am4 cpu (barring the apus/ones with igpus essentially) had ecc support anyway

[jade scaffold]

Yea it's a per mobo basis

But there are dedicated server boards for AM5

[sonic meadow]

as there were with AM4 😆

and also for a bunch of intels consumer sockets (which also had xeons available for them typically)

[jade scaffold]

Just wondering what the config of them will be

If they do a few with zen 4c cores possibly upto 32 cores on am5

[jade scaffold]

Wonder if they can increase pcie lanes

Hell if they could get 32x gen5 that's enough for a chipset + 3 16x gen 4s and a 8x gen 4

[sonic meadow]

and what would they steal the pins needed for the extra 4 lanes from?

which would also make it incompatible (in both directions) with existing am5 hardware

[jade scaffold]

If it's using RDIMMs it won't be compatible with normal AM5 anyway

RDIMMs are electrically incompatible with normal DDR5 DIMM slots

And I guess you'd never need an igpu on an epyc

So take the pins meant for the I-GPU?

[sonic meadow]

its either have one on the chip, or have one on the board somewhere

and am5 already has the interfaces for it on the chip

[jade scaffold]

Yea but the igpu on the mobo does more than graphics

It's usually also the BMC chip

Needs a GPU snyway

Soooo you could just rob the igpu pins I guess

Or use some pins as dual purpose

[sonic meadow]

they also typically do less than graphics. modern graphics solutions (even/especially igpus) tend to offer things like hardware video encode/decode, let alone the small amount of compute bandwidth they offer

[jade scaffold]

That's true

But it's an EPYC

So fuck the consumers

-amd probably

[sonic meadow]

I imagine the platform costs will be substantially less than SPwhatever epyc/tr chips

[jade scaffold]

Mobos maybe

CPUs honestly

You can get an 8 core epyc with 6 channel memory and 96 gen 5 lanes for £400

[sonic meadow]

the real reason may in fact be simpler: am5 isnt sellinjg as well as expectd in the consumer space, so they have excess inventory and are looking for ways to diversify it

[jade scaffold]

Does normal AM5 have AV1?

[sonic meadow]

I dont know if it has either encode or decode

[jade scaffold]

Epyc has it it's one of the main features

Sorry not av1

Avx512

[sonic meadow]

r5 7600 has avx512 https://www.amd.com/en/product/12756

sorry for wide image

I dont know how well it sustains it though, as avx is typically a very power/silicon intense workload

[jade scaffold]

Wiiiiide

[sonic meadow]

#just1440pproblems

[jade scaffold]

On epyc it doesn't have much of a performance impact

Just because the tdp of epycs is so high

Like my 16 core has a 400w tdp because sure why not

The 8 core epyc which has the c type cores and those are only gonna pull like 10w has a 90w tdp that Io die for sure is responsible for 80w of that

[sonic meadow]

it was not uncommon (and might still be the case) on intel where they would downclock while doing avx workloads because it is such a hungry operation. I dont know if amd did the same thing or not

[jade scaffold]

How an AM5 epyc would fair is a different matter max power of 200w I think AM5 is rated for

[sonic meadow]

170w according to wikichip

and wikipedia I think

[jade scaffold]

That's the max a CPU will normally pull by default but you can safely have them pull alot more

Same way sp5 maxed out at 400w but physically it's capable of well in excess of 1kw

[mossy gull]

I would go for 1080P, more performance overhead

[jade scaffold]

yea the screen is also tiny

tho tbh

the price difference is like £20

so like

[mossy gull]

Still, the extra pixels will have a performance hit

[jade scaffold]

only if you are running at that resolutioin not gonna get much of a performance hit just from driving the pixles

[mossy gull]

Fair enough, I just don't see the point, I think I am gonna get the Legion Go😐
Or GPD Win4😐

[jade scaffold]

im tempted to get it tbh

the price is actually fairly reasonable

wonder how well winulator will run on it

if the GPU is faster than the Snapdragon 8 gen 3 it might actually be able to do gta V in 1080p

hmmmm

[mossy gull]

I just need a Windows machine

[jade scaffold]

AM5 Epycs comming out at some point

may be able to get your 24 core + requirement with multiple full length slots on a AM5 chip

[mossy gull]

I mean a portable system 😅
Also I stay with the big Threadripper

[jade scaffold]

just make sure you get rev 2 boards

and be prepared to pay 1.2k for a mobo

[mossy gull]

I am prepared to pay 2500.- for a CPU, just so I can run 2 GPUs at full speed
