And yes, it took some work to configure that with Debian.
Starting from installing on btrfs instead of ext4, and then adding and configuring extra package.

Some other distros do it by default.

mistakes are part of learning

#

i know that saying fairly well.....

#

Do you know that moment in a project when you're realize it's a hopeless case, so you just abandon it and start a new one?

Unrelatedly, I have two younger siblings.

#

Do you know that men snore because their body can't find another way to be annoying when asleep

maiden coyote
#

is the number of slots stored in the bios?

#

as in if I've got a motherboard with traces connected pads for 2 more slots, soldering two more in wouldn't work without a modified bios

#

well apparently someone has tried, and failed

twin dew
#

The comments on the hackaday post mention the resistors that would need to have been populated at minimum.

#

From someone with schematic for the MB.

languid gulch
maiden coyote
#

There ain't really no telling if they were populated or not. I haven't looked at my board much more than it had tinned pads for 2 dimm sockets

#

Can't tell from the picture. He did mention it posted the first time he tried, and then he put heat to it again and it didn't post anymore.

#

Resistors are cheap enough, if they spent the time to put traces and pads for another socket there's a good chance they put the resistors on

twin dew
#

As in the PCB has the places for those, but they are most probably unpopulated too.

#

Because removal of installation of the resistors is small thing to do, and saves both component cost, and pick&place machine time.

maiden coyote
#

Because they're dirt cheap, and not having them may allow for induced currents on the traces that could cause other issues

twin dew
#

When the specific traces don't connect to anything at one end, and to CPU pins that are unused when the slot isn't in use at the other?

maiden coyote
#

The cpu pins on my board would be connected, it's an i5 that does support 4 slots.

#

Having voltage present on something that shouldn't have any can do wonky things. I'm not an EE. So I could be wrong.

twin dew
#

Yes, but what the traces state is isn't important when they aren't used.
And the CPU end will keep them in good enough control.

maiden coyote
#

I mean these are a little more expensive than I thought

twin dew
#

So the slot end termination resistors etc. don't need to be there.

maiden coyote
#

That's mouser prices though. I'd expect them to pay half at most as an OEM

#

I've seen board without stuff that have all of the supporting components, and I've seen it where there's nothing

twin dew
#

And then there is the pick&place machine time, optical inspection machine time, etc.

#

More frequent changing of component reels, and so on.

maiden coyote
#

I don't think they'd be worried about that

twin dew
#

Large scale manufacturing is absolutely worried about those.

maiden coyote
#

Not compared to the amount of shit already on the board, 10 resistors isn't going to have a meaningful cost saving

jagged snow
#

They will over 2m units

languid gulch
#

k, dumb question time. when it comes to water cooling both a cpu & gpu, & you had to do something like 2 separate rads of unequal size, is TDP the deciding factor as to which component would get the bigger rad? (i assume that would almost always mean the gpu gets the big one)

jagged snow
#

Optimally, your loop would look something like pump/res > cpu > rad > gpu > rad

maiden coyote
#

Sometimes they're there sometimes they're not. I can't know why

jagged snow
#

But that's not always possible

languid gulch
#

like i said, if you got stuck with some kind of weird-ass layout where one rad had to be bigger

jagged snow
#

Then yeah, whichever part had the higher tdp would benefit more from the rad with more dissipation capacity

twin dew
languid gulch
#

i have no idea if it exists, but something like a case where you could put 140mm wide stuff on the front, but to make room for the mobo connections it was only a 120mm width up top or something

twin dew
#

Upfront cost vs. per-unit cost optimizations in work.

jagged snow
twin dew
#

So company, expected run-sizes etc.

jagged snow
languid gulch
#

width, not height

jagged snow
#

Yeah

#

It's more common to support wider stuff on top than in front

languid gulch
#

really?

jagged snow
#

In my experience, yeah

languid gulch
#

that seems counterintuitive

jagged snow
#

Lots of cases are set up for three 120s in front and two 140s on top

#

Mid tower anyways

#

If you go full tower they're sometimes 140 all around

twin dew
#

Or that the front can do 2x140 or 3x120.

jagged snow
#

Yeah, that too

twin dew
#

As there isn't enough height in the case to fit 3x140.

Yeah, it's making my PC crash 😂 (but the culprit is probably CPU dying)

wary olive
#

Anyone in here good with software/wifi stuff?

jagged snow
#

But yes

wary olive
#

Ive been having problems with ping lately but only on my newly build pc. I have gigabit internet and on everything else I almost never have ping issues. Ive tried changing it to tell the router its a game console instead of a desktop pc and that didnt work (Xfinity). I tried changing the quality of service to prioritize my pc but my router doesnt have that option. I got no clue on what else I could try

#

Wifi connecter and not Ethernet

charred pewter
#

wait, you said xfinity ... well theres the problem.

#

everything behind their router in your house is prolly all 1ms to each other ... the issue is going from their equipment to their equipment further out (which is nothing you can fix)

#

BUT ...

#

you say it 'only' happens on the one machine, all your other machines you have no issues (im assuming you are trying ping tests to the same external destination)

wary olive
charred pewter
#

did you happen to try a different ethernet cable? (not meant to be funny)

wary olive
charred pewter
#

hm, plug in the included antenna(s)?

#

wifi for me has always been very pingy... so i try to do wired at every possible point

#

i even ran a 100fot cable downstairs to my tv room switch to plug the tv/blueray/htpc in direct 😄

wary olive
wary olive
charred pewter
#

could just be that board/controller ....

#

tried test-moving around (further, closer) just to test if its not something about where you have it ?

wary olive
charred pewter
#

tbh i never put my motherboards included wifi to the test .... i used it to setup windows11 and once tht was installed, i plugged the fucker into the switch and forgot i had wifi built in 😄

hmm weird

wary olive
#

every other device runs around 10-30 consistent

charred pewter
#

do you have the duplex mode set to autonegotiate ? maybe force it to full duplax and see if it behaves better?

#

(is the duplex setting even present on wifi controllers?)

dire igloo
#

I assume that means "I ordered them and I'm waiting for them to ship"

wary olive
charred pewter
#

find your adaptor in Device Manager, then get properties on it, then click over the Advanced, and then find the duplex choice in the big list ... if it has it

#

my wifi adaptor does not have the choice... but my wired adaptor does

#

so that prolly wont help you...

maiden coyote
#

The system has found unauthorized changes on the firmware, operating system, or uefi drivers o.O

#

I guess I've done something this bios really does not like

winged valley
#

Either UEFI security violation you didn't account for or changed a monitored value

wanton orchid
#

did you give up networking then ?

winged valley
#

That's my guess

maiden coyote
#

The BIOS reset itself.. I know because Vt-d and virtualization was disabled. Not sure how or why that happened. I'm probably about to have a very buggy server.

#

so now it won't boot the OS.. which is fine.. I was going to reinstall it anyway before bringing it online.. setting up PCI passthrough again is going to suck

tough owl
#

winged valley

i completely forgor

jagged snow
#

Canada is trying to ban the flipper zero

twin dew
#

Because some representative has seen too many internet videos (real or not real) about how it can be used to steal cars...

#

When the device designers say that it shouldn't be able to do it for any car newer than from 90s or earlier, without separate extra hardware at minimum.

#

And when the stuff that the actual professional car thiefs use is completely separate.

maiden coyote
#

now this is a fan

#

well, I'm able to install drivers for my gpu on a windows guest, but I can't get the gpu to output a display to a monitor..

edgy hazel
maiden coyote
#

oh windows..

#

I wonder what I broke now. signing out/switching accounts makes it bluescreen without fail

twin dew
#

Whops, I installed Win11 22H2 and not the intended 23H2 January Update...
Loaded wrong ISO on the emulator.

#

Fortunately that is just test OS install.

#

Just means more updating.

edgy hazel
#

Ah don't worry. We all know that windows is very good at updating

twin dew
#

Didn't even give option to update to 23H2.
Had to start from the right install image.

#

IGP or something else isn't happy with some setting, and is causing the Windows to freeze up.
The system is active in the background as event logging is still running, but the monitor picture will freeze and the system doesn't shut down when pressing the power button like it should (short press to tell Windows to start shutting down normally).

edgy hazel
#

I still need to fix my disk situation. I had popOS originally set up to dualboot with windows, so I had to set up some weird partitions and all. But... I don't use windows anymore...

twin dew
#

Happened in Win10 when running TM5 but not otherwise (but monitor picture blibbed to black for one frame at times when RAM was under heavy load).
But in Win11 it was worse, so time to diagnose more.

#

So run TM5 until if freezes, change one RAM timing to auto, do it again, until it doesn't freeze anymore.
And then start reapplying the others.

#

But seems it might just be the RAM refresh rate settings?
tREFI and tRFCs.

#

Or tRAS and tRC that were way below what the common "theoretical minimum" was.

twin dew
#

Because that still caused differences in memory tests.

edgy hazel
#

man I'm learning so much stuff 😄

#

for example: if you enable a firewall on your server, make sure port 22 is still open after that

twin dew
#

tRAS 30 didn't work...
But the minimum that should ever be used in my system is 50 (which worked)...

#

40 didn't work, 46 at least worked at Windows Desktop when the system froze in that point in previous ones...
Lets go to 42 and start raising it from that.

#

44 seems to work.

wanton orchid
twin dew
#

Seems that tRAS 44 with tRC 44 is stable in quick test.
When they "should" be 50-90 as minimum from the other timings.

twin dew
#

No, black screen when started moving mouse after a while.
While TM5 was running.

#

Case fans immediately went down to minimum speed too.

rustic panther
edgy hazel
#

nginx is driving me nuts

tough owl
#

when isnt it driving you nuts

twin dew
#

No, tRC 50 isn't completely stable yet, got momentary black screen with it.
Haven't got one yet with 44-90.

twin dew
#

Got one quickly on 44-60...

twin dew
#

44-70 didn't work either.
So might be time to throw in the towel and go with the 50-90 that should be the actual reasonable use minimum anyways....

twin dew
#

And seems the first contender for firewall & HIPS solution will be ESET Home Security Essential.
Spyshelter has just fucked themselves by releasing new version as public beta, and stopped selling the older version.
And changing the pricing to be stupid, with just 2 computer or 25 computer prices, when I need 3 lisences.

#

And if the UI doesn't work for me, need to test the full Comodo suite next.

pure karma
edgy hazel
#

the time I spent trying to fix nginx when it's just a webserver running dockerized without a WEBSERVER

winged valley
twin dew
#

"Bad" results for antivirus detections on some tests, good in others.
But one of the few that seem to have the HIPS and firewall features I want (complete manual control).
Which are painted as bad thing in some of the reviews.

#

But need to check the UI for those HIPS and firewall popups.

maiden coyote
#

It bsods if I tell it to shutdown or sign out

pure karma
#

you know its bad when the bsod stacks on top of windows instead of resulting from windows crashing

edgy hazel
#

bro got bsod themes

pure karma
#

alienware moment

maiden coyote
#

So apparently I installed the wrong passthrough drivers.. they worked, but they were for win2k something and not win10.. I wonder if that's why the system BSOD'd

so, to that, format and reinstall (:

I'm not sure why it had a RF (channel 3) on a composite plug.. kind of strange. I guess maybe they had some kind of automatic switch that would switch the tv from cable to the atari when you turned it on

cinder moon
#

I can't see what justifies buying the WD here.

rotund hamlet
#

is the Toshiba model SMR?

cinder moon
#

It's CMR.

#

"• 22TB capacity
• Conventional Magnetic Recording (CMR) for broad compatibility"

rotund hamlet
#

hmmm odd

cinder moon
#

Yeah. Consumer vs cloud drive, seems like the cloud drive would be vastly better for consumers too.

#

A 5-year warranty on the Toshiba too..

jagged snow
#

Yeah, I'd go with the Toshiba there for sure

languid gulch
#

ok speaking of large spinning rust, got a dumb question

#

sata power & data, what's the 3rd connector on them

jagged snow
#

They're jumpers, if you're talking about what I think you are

#

Typically only found on hdds

#

Can allow for settings like low-power spinup

#

Iirc the rps is mostly used to allow for USB compatibility

languid gulch
#

yea this one

twin dew
#

Also some HDD:s have com-port access there for debug console access.
Rescued one drive with broken firmware via that.

#

Some drive in the past had firmware bug that bricked the drive when it had been on for long enough in total time.
But you could recover it to operating status with that access.

twin dew
#

Also I bit the bullet and ordered Radeon RX6600 for 230e to replace my current RX580...
Hoping I have to use it for only half a year or so before I can gift it forward in family.

#

Next option would have been RX7600 for 300e.

twin dew
#

And on ESET, at least the firewall dialog is pretty good.
The rules management is somewhat bad, with entry per rule, in creation order, not grouped by program.
And no program profile support.

#

Network profile support is good, and the way it can set the program info the rule will apply to is good.

twin dew
#

Same with HIPS side.

So the parts of the UI to create rules are good.
The parts to manage rules after their creation are bad.

#

But I think I can live with ESET.
But need to do full trial config first.

#

HIPS side allows for wildcards in middle, so you can edit the rules for programs that version their install directory to match one rule.
And Firewall side supports Store Apps (which are the worst offenders of the previous) natively.

#

No, HIPS threw an error after saving the rules completely after that wildcard edit...

#

So currently wildcard can only be for the specific folder slot, so something\*\something,
Not something\something*something\something.

languid gulch
#

think you made a good call with going with the 6600, while the price increase matches the performance increase, it feels like the 7600 is right at the bottom of the next tier up, & at the point it'd be worth making a more significant jump. this was you can put that cash towards something else

twin dew
#

6600 and 7600 would have had pretty much same price to performance with the TechPowerup simplified scaling number.

languid gulch
#

yea basically

#

but also for around that price you could hunt down a 6700XT

#

bump up to 12gb vram

twin dew
#

Starting from 390e for new here in Finland.

#

Sorry, 6700XT not available at all, that was for 6750XT.

languid gulch
#

ouchie, but maybe even worth it in the long run. idk why, but it really does seem like phat vram is the future

twin dew
#

Yeah, but hoping this will be just 6-12 month stopgap.-

languid gulch
#

oh definitely

#

also what i've learned is that while being able to put settings to max on everything is fun, there's a lot of games from the past couple years where even keeping everything on low, but cranking draw distance still looks plenty good

#

or maybe that's just me being old & remembering garbage textures from the past

twin dew
#

And that is still 68% uplift from the current GPU.
And I can replace Radeon 280 in relatives computer with the 580 (after possible fan swap).

languid gulch
#

wow a 280

twin dew
#

And the 6600 is destined to go there if I can get the real upgrade.

languid gulch
#

definitely jumping a tier up on 2 systems, nicely done

twin dew
#

Perfectly fine for Fortnite and Minecraft.

#

And it was free.

languid gulch
#

6600 is basically an AMD 1080 that's 100W lower TDP

twin dew
#

And the 6600 will be perfectly fine for Satisfactory at Full-HD.
And can run (almost?) all current games to playable degree.

languid gulch
#

oh 100%

#

at least at a bit above minimum

#

so long as you're not trying to do 240Hz

#

I'm very glad I replaced my mobo. Testing the 5900x open air with a thermal camera showed the vrms were getting hotter then the cpu die at full load (tested with a Deepcool AK620) CPU was hitting 82c vrms were measured at 91c

#

Sure that's within area of operation for the mosfets still quite hot

twin dew
#

Thermal cam readings are complete crap if it isn't calibrated for the exact material being looked into.

#

And 91C for VRM is perfectly fine.

sharp oasis
#

I tryed to have it calibrated for the aluminum heatsink that's on top of the vrms.

twin dew
#

And any shiny surface is always a problem.
So adding black tape or like would help on that.

sharp oasis
#

The heatsink is painted flat black from factory

twin dew
#

So pretty close to optimum surface, still needs that emissivity setting for the point being measured.

sharp oasis
#

I'll check calibration and try again later today

twin dew
#

FLIRs site tells: put black electrical tape on the part, wait for it to equalize and use 0.95 XD

#

For emissivity.

twin dew
#

Anyways, the weird steps I'm going to be taking next week.

First get the ESET set up and trained for basic Win11 23H2 system on the new computer with throwaway OS.
Make saved config to use as base on later three setups.

Install Win11 with CPU list bypass on my laptop.
Set it up.
Move browser settings and profiles etc. to that from old main computer.
Check ALL the stuff I can find and document what settings changes I want to do in Group Policy, various other Windows settings etc. for the later two Win11 installs.

Backup things from old systems SSD RAID-1 to HDD RAID-1 and set permissions for the files on the HDD partitions to not be restrictive.

Remove the new system from secondary system case.
Remove the old system from primary system case.
Build the old system in secondary system case with another separate SATA SSD as storage.
Install Win11 with CPU and TPM bypasses (TPM 1.2 available like is needed, just no 2.0 like is required).
Set it up.
Move browser settings and profiles etc. to that from the laptop.

Build the new system in the primary case.
Put one of the old SSDs into the new system, leave the other one untouched for now as safety measure and backup.
Install Win11 on the new system with the single SSD set up to be ready to be converted into RAID-1 again (in addition to the new NVMe drives and new HDDs already in RAID-1s).
Set it up.
Move browser settings and profiles etc. to that from the old systems new OS.
Connect one of the old HDDs to the new system temporarily and copy all the stuff over.

Once everything is checked to be right and in place, connect the second SATA SSD and convert the pair to RAID-1.

Too much work coming...

And ESET SSL MITM disabled...
Yes, it would in theory allow for early detection of bad stuff, but it also has in past allowed bad stuff to happen when the MITM code had bugs.

Say like two separate 5600s clustered together to get a total of 12 cores and 32gb ram

#

I know it would be incredibly latent transferring data over say ethernet.

fringe ivy
#

You should check into a Beowulf cluster.

#

"Parallel Cluster (Beowulf)

The Parallel Cluster is a bit different than the others. Instead of clusters acting as one which is located far apart, the Parallel Cluster makes multiple systems act more like one large system of processing resources. Without getting into programming, the application must be written in such a way as to allow multiprocessing."

I also did a quick search I can do it but I need to bridge the systems by Pcie to try to get a decent rate of speed. So probably getting two Gen4 boards and seeing if I can link them both on a X16 slot

fringe ivy
#

You could use fiber channel

sharp oasis
#

That would work as well. But I do think a riser cable is a bit easyer to work with. As I have two Gen 4 boards and 64GB/s is more then enough bandwith.

yubi supports FIDO

The FIDO ("Fast IDentity Online") Alliance is an open industry association launched in February 2013 whose stated mission is to develop and promote authentication standards that "help reduce the world’s over-reliance on passwords". FIDO addresses the lack of interoperability among devices that use strong authentication and reduces the problems ...

I am asking because I was considering buying yubikey but not sure if it's worth it since I guess websites would need to support it

because websites need to implement it and there is nothing Yubi can do about it.

In that respect, it's pretty good. The only service that I can think of off the top of my head that supports it directly is github, where I use it as a single factor for sign on

Oh right, I also use it for my password manager

I use duo authenticator for all of my 2fa needs that don't support sso or yubikey

But yeah, the big ones seems to be Google, AWS, Apple, 1password / lastpass..., X (Twitter), ...

They say YouTube too. But that's a bit misleading since youtube is Google. And Google was already mentioned hehe

Steam is very intent of forcing you into using their mobile app for auth

Yubikey is a candidate for single-factor authentication

I have a few services configured so that I can use either just the yubikey or a password and 2fa app combo

maiden coyote

So if yubikey goes down, do you lose acess to those services?

jagged snow

Nope

#

It's entirely hardware-based

Is it like Googles pw manger where it gives you a super strong password?

So yubis servers have nothing to do with you logging in?

I've always trusted a strong password, and my notebook lol

jagged snow

I do recommend that you purchase two of them, and use one as a backup. Whenever you configure a service, set it up with both of them so that if one ever gets lost or damaged, you still have access to everything

#

My workaround to that approch with pw+2fa as alternative sign in is passable but technically not as secure

If you break into my house and get my notebook and I'm not home to provide free lead, well I've got more problems than compromised passwords

I have a very specific question nobodyu has been able to answer

What's the question?

winged valley
#

Let's say you have the standard for 315 ball TFBGA LPDDR5

#

Lets say both Micron and Hynix make it

#

Assuming all the voltage values are the same between both brands, would I reasonably be able to expect chips from Micron to work on a board designed for Hynix

#

Or would the pinout be different because the only standard part is the LPDDR5 technology foundation

jagged snow
#

Probably
As long as all the chips are the same

winged valley
#

The same as in same voltage and amount of balls?

winged valley
#

Considering these are links to datasheets

#

I assume you want me to compare pinouts?

jagged snow
#

Was going to reccomend, but it doesn't appear that either manufacturer specifies

winged valley
#

I know micron does but you have to dig deep and they only give access to people in the industry or academics

#

(apparently repair is a valid credential bc they let me in lol)

jagged snow
#

And my understanding is that there is very little in the way of requirements for pinout on the ic

#

So I'm going to revise my earlier statement and go with probably not

The IGP should only need about 256MB or less of RAM for Windows desktop usage.
And the RAM used by IGP in dynamic mode isn't really shown as "lost".
If the OS is showing that it only has 2GB to use, and IGP is marked as having 2GB dedicated, then it is BIOS setting problem.

#

With caviat that I might be wrong, but AFAIK LPDDR is standardized to same level as normal DDR is, which is complete interchangeability of chips with same form factor, only limited to the speed grade etc.

#

And the differences only come into play when you go into OC territory (which almost all consumer DIMMs are in)

sand saddle
#

Iphone battery in cold temperatures is a joke lmao

#

Maybe not the battery itself, but the sensor definitely

#

Watched it go down from 22 real time, but it’s actually much higher than 22 or 1 for that matter

twin dew
#

Li-Ion current giving capacity goes down after 0 C.
And the voltage droops.

Detection of the "battery is empty" is based on voltage.

#

Most off the way for the battery gauge is just current tracking.
But the low end is based on voltage.

#

Same for very highest end.
Just that with Li-Ion and derivatives, for most of the middle the voltage is static.

#

Except for those temperature effects to it.

sand saddle
#

But I only see it happening to Iphones. I guess other phones have the sensor closer to heat sources like the cpu.

twin dew
#

It is about the battery temperature, not voltage sensor temperature.

sand saddle
#

Then ig the other phones run hotter internally, idk.

#

It’s not even below freezing for my phone

twin dew
#

Or have temperature compensation in mix.
Measuring the battery temperature for safety purposes and using that measurement for the voltage interpretation?

sand saddle
#

Maybe

twin dew
sand saddle
#

Like sure, outside temp is a little below freezing, but I can already see the battery start fucking with me at like 10C or smth

#

Can’t say the temp for sure, cuz the phone is nearly never at outside temp. If it’s in my pocket my thigh is heating it and if it’s in my hand the phone is working so it’s generating heat itself.

#

Looking at the 1% is quite triggering considering it’s actually at 50%+

twin dew
#

How do you know it is actually 50+%?

#

Because anything between (10-20) - (80-90) % is just guess by the device trying to calculate based on what it expects the total battery capacity to be, and by trying to track the power usage.

jagged snow
#

To an extent, the voltage curve isn't perfectly flat there

twin dew
#

The middle part is so flat that the uncertainties are larger than the change.
So it cannot be used.

#

Try to use that middle for anything?
When the current draw etc. will cause larger swings from resistances than the actual battery voltage change.

#

And you never go anywhere near that 0% true SOC, as hitting it will kill the battery, and possibly cause a fire.

#

First time you hit it.

#

Same at the high end, charging to true 100% charge causes many times more degradation to the battery than little less.
So for electric cars for example, the car might only charge up to 90% true, and use 20% true as "0%".

#

Phones and laptops do it closer to the true, but still not exact to it.

#

Ok, there was difference in the curve even above 0C, just that the changes are much smaller.
And note that this is at specific discharge rate, that affects things too.

#

LiFePo seems to have more usable voltage drop when not at very high discharge rate.

sand saddle
#

I had just charged it recently and wasn’t using it intensively

#

Fyi, I’m not inside and it’s still at 1%, I’ll try plugging it in

twin dew
#

So the quick drop started already from 75% or so.

sand saddle
#

Well, it’s when I went outside to go on the bus

twin dew
#

That drop between the green bars was larger than normal, even while the device is in use.

sand saddle
#

Yeah no shit, the sensing is busted

I have invented iPhone fast charging, 11% now

sand saddle

edgy hazel
#

If you say you "edited it" you're just saying edit twice

twin dew
#

Like I said, the shown 0% isn't anywhere near the true 0%.
It causes the battery to lose capacity faster when going under 20% or so regularly.

#

The dying is because a safety circuit trips.

#

Which is set significantly above the true 0% SOC

I would like to do fresh windows install on my laptop too. Maybe try Win11 as well

twin dew
#

But I'm using official "Business editions" image, and that means that it doesn't force MS accounts either at stock.

And the laptop fulfills all but the CPU type requirement.
And the CPU check at install one might only care about amount and speed.

#

For VM compatibility.

tribal kraken

twin dew
#

So ESET has offline installer, but you cannot do anything afterwards without network access to check lisence, cannot even start in trial mode without internet check...

#

Would have been nice to set up the HIPS and firewall before connecting the system to internet...

#

And if Antivirus can be used if you don't ever connect the system to Internet?
What is the point of that?

#

So even if it allowed 30 days trial without the internet check when it cannot?
And only checked when there is internet connection?

#

Yes, and Defender has ACL feature, but it is PAIN.
And Windows Firewall has so huge hole in that any installer can add "allow incoming to me" rules without prompt...

#

It is nice base when you set it to "ignore incoming rules" mode.

#

So it block EVERYTHING incoming, no matter what rules have set.

#

And there are some better UIs for it, that AFAIK can be set to automatically delete installer rules additions.

#

The version 17 is very new.

#

The previous ones used different activation scheme.

#

Think I'll buy 4 lisences instead of the now needed 3, so I have one extra for possible VM.
One costs 40e, then 5e extra for each additional one.
So 50 vs 55e for a year.

Could have monthly but then price per month would be 10% of the yearly, and automatic billing would not be optional.

#

Thanks... Need to check couple of things first.

#

So by changing the motor controller you changed what would work...

sand saddle
#

Lmao

twin dew
#

Moment, checking what the circuit is doing.

sand saddle
#

I’m going to check how well the pump works that I ordered

twin dew
#

I did mention that when checking many of the motor controllers were using this type of circuit with 555-timer.
Where the thing is current controlled in a way.

#

And the one high power wasn't.

#

This one only has single diode, not two, but it is close.

sand saddle
twin dew
#

No, just that I need to decipher how the implementation works, and cannot just read about the "standard" implementation.

#

Once the stream ends, might check one of that guys modification videos to see what he does.

sand saddle
#

I'm gonna try to use it as it's meant to rn, see how hot it gets and such.
I have to find an adapter for the pump to get a garden hose connected to it.

#

the enshittification continues ... amazon removed high fidelity streaming unless you pay for the 'ad free' tack-on

twin dew
#

So it is this basic one from Wikipedia:
With R10 + red-to-yellow potentiometer part as R1, and R11 + yellow-to-black potentiometer as the R11.
C4 on PCB is the C1 and D3 on PCB is the D1.

So hoping that this might work by removing C6, setting the pot to max and connecting the converter output to the C6 chip side pad.
But need to check what that reviewer that checked the other motor controller does with the mods he does for the other controllers so Pi can control them.

#

No, sorry, the black is connected to the middle and yellow to the bottom.

#

Ah, different colors on the wires compared to the amazon image.
Like the components are surface mount on the one you have and through hole on the pic.

#

So pot wiper is in the pin 7, like it should.

#

But that pin 5 overrides the reference voltage for the 555.
So that should work.
So that pot on max speed static voltage control on that should change the duty cycle.
As it then changes the reference levels for the pins 6 and 2.

#

While not changing the charge or discharge speeds of the C2, which determines the voltage that the 6 and 2 see.

#

By default the reference levels for the 6 and 2 are 2/3rd and 1/3rd the VCC.
But with pin 5 in use they become 2/2 and 1/2 of the pin 5 input.

#

But time to look into the past to find that youtube channel...

twin dew
#

Ah, he had video of the exact model (just with the through hole?)

#

For control from Arduino.

sand saddle
#

Very odd to be living in a household where I can look for stuff instead of buying them, but if I only knew where to look…

#

(I’ve been living in the same place for my whole life)

maiden coyote
#

Most of that stuff would be arduinos rather than pi's. The concept is identical though.

twin dew
#

Ah, just using the 5V PWM output from arduino, so not usable in this case.

#

Bypassing the whole 555.

#

But as Pi:s PWM outputs are 3.3V, would need to check if that is enough.

maiden coyote
#

The pi has a pwm output.

#

3.3 should work.

twin dew
#

But yes, probably works.

maiden coyote
#

3.3 can usually talk to 5v. In this case it'll depend on the mosfet that's driving the motor

#

If 3.3 is enough to saturate the gate then you're good

#

I think the pi pwm libary was depreciated. Not sure on that

#

I remember people made FM transmitters using it lol

twin dew
#

Close, for the FET the review guys unit used STP80NF70 fets, that have 2-4V gate threshold voltage, with 3v as typical.

#

Also could just use the RESET pin of the 555.

#

With Pi PWM output.

mental oriole
#

Managed to break a Xilinx SoM by debugging out custom pcb with jtag 🤣

twin dew
#

So when the Pi PWM output is low, the chip is stopped, and when Pi PWM is high, the chip operates.
And set it to just always have the 555 output as high when it is operating.

twin dew
#

Problem with the reset version is that the reset pad is connected to the VCC trace under the chip.

#

So either the pin needs to be raised, electrical tape or like be inserted between the pin and pad, and then wire soldered to the pin.
Or whole chip removed, trace cut, and then chip resoldered.

sand saddle
twin dew
sand saddle
#

I could ask a guy ig?

twin dew
#

So the better option would be to unsolder the chip, cut trace between te VCC one and the 4/RESET pin where I marked.
And then resolder the chip back.

maiden coyote
#

Well for that stp80nf70 it says Vgs is 20V max with a threshold of 2-4V

twin dew
#

And then connect the RESET pin with wire to the Pi PWM output, and some ground to pi ground.

twin dew
#

When we can just use the 555 as 3.3V to 5V converter.

maiden coyote
#

Is that the reset trace passing through j2 and c2 silkscreen?

twin dew
#

From J2 to pin 8.

#

And should connect to that Pin 4 too, which needs to be separated from that 5V VCC trace.

#

Comes from 5V regulator on left, feeds the red pot wire through resistor, and the reset and VCC pins on the 555.

maiden coyote
#

Easiest way is to cut the trace with an exacto there and scrap the enamel off if you need to solder a jumper, or solder the jumper straight to the pin on the chip.. both depend on how good you are with smd soldering

twin dew
#

Problem is that the point where it needs to be cut is under the chip.

maiden coyote
#

Use this to desolder it

twin dew
#

So need to remove the 555, cut the trace going to the pin 4 pad, and then resolder the chip.

#

Or do just that left lift.

#

Which would be worse for longevity in theory.

sand saddle
maiden coyote
twin dew
#

But I would personally do the chip removal, trace cutting, resoldering and then connect to that pin&pad with wire and solder to that C6 Gnd throughhole for ground.

#

As it is close and not masked on either side of the PCB.

sand saddle
#

Very good pressure for a 25€ pump, just needs to last until the end of this project

twin dew
#

For documentation, before I close Paint.

#

(there are tiny markings there you can only see when looking at full pic)

sand saddle
#

Cuz I bought it

twin dew
#

Not with that thing, as you cannot replace the pot with it.

#

It could in theory be used to feed that CONTROL pin instead.
So that 3.33V to something lower would change the PWM the 555 generates.

#

For which you would need to remove the C6 cap and solder wires to both of its pads.

#

But the reset pin trickery would be better.
Just didn't know enough about the circuits those things use when I told you to buy it.

#

Sorry.

#

Could have been used with that 60A(?) board.

#

Which did similar 555 reset trickery to drive it with PWM from the unmarked chip that also showed the duty cycle with that display.
As that chip seemed to be just using voltage input from the potentiometer.

#

But in this board the potentiometer is changing the current, not voltage.

sand saddle
# twin dew Sorry.

Np, you’re very helpful and it’s amusing seeing you put so much effort into this, I understand it’s interesting for you.

twin dew
#

Also could just use almost any fast enough 5V MOSFET that can work with 3V control to bypass the 555.

#

Or two if you don't want to deal with inverted output in software.

#

Where 100% PWM would be 0-speed and 0% PWM would be max speed.

#

But doing the reset mod would probably be easier.

#

But time for me to go get the new GPU from dropoff and refill refrigerator on same stop to store.

sand saddle
twin dew
#

No?
Just that the PWM the power stage of that motor controller will be same as the Pi outputs.
When currently the potentiometer sets what PWM output the 555 outputs.
And the power stage then smooths the PWM.

#

Like with the board in base config.

#

Idea is that you are toggling the 555 between reset (output low) and operation (output high, as long as the next reset is sooner than the normal circuit function).
By passing the normal control input for the 555.

#

And using the 555 on the board as just 3.3V to 5.0V converter.

#

So not "original" PWM (Pi) -> DC (converter board)-> PWM (555)-> DC (power stage)
Just PWM (Pi) -> 3.3V to 5V conversion (555) -> DC (power stage)

#

Or the boards native: Pot controls and some of the other passives control the 555 to generate PWM signal, which drives the power stage.

So responsible it refuses to answer any of your questions lol

twin dew
#

Because ChatGPT etc. don't know math.

#

So it cannot calculate 2+2=4, it can just infer that in the data it was fed, "4" was the most common next symbol after to "2+2="

#

Or it might hallucinate some other completely weird answer.

visual tree
twin dew
#

Which the various bots did before, and that kind of normal programming prefilter was implemented.

#

Same for the next one.

#

All those "refuses to answer" things are separate code acting as filter before the input is passed to the "AI"

#

And just feeding manually written answers if the prompt seems to fit some manual algorithm trying to detect questions that the AI often hallucinates with.

#

Implemented old-style chatbot acting as filter to the "AI" part.

#

Ah, damn, the C4 capacitance isn't marked.

sand saddle
#

You don't need to bother too much right now, I'll try to compile what you've said and see how my group decides to move forward.

twin dew
#

Set the Pi to output PWM signal at suitable frequency.
Connect the PWM output pin to that Reset pin of the 555.
That will drive the motor based on the Pi PWM output duty cycle.

Needs at least that single trace cutting under the 555 chip on the PCB and soldering those two wires.

sand saddle
#

I really don't understand why right click copy and paste doesn't work in docs

#

I like using it when my hand isn't on the keyboard

twin dew
#

Too low PWM frequency on the Pi, it doesn't fully override the potentiometer.
Too high PWM frequency on the Pi and the power MOSFETs will first heat more, and at some point will stop working properly when going very high.

#

And with couple extra mods, the pot can be removed completely, but that means that the Threshold and Trigger pins need to be connected to VCC and Ground, one to each (didn't check which to which).

#

And that too low PWM on Pi doesn't affect anything after that, just makes the motor not run completely smoothly if going way too low.

#

Idea of PWM is that at suitable frequency, the almost square wave acts like specific voltage level if the load is suitable.
So you can do control to intermediate values/speeds/brightness by switching between on and off quick enough.

#

Just that it needs to be high enough frequency that it averages out.
And low enough frequency that what is being driven can handle it (the power MOSFETs in this case).

sand saddle
#

How easy is it to mess up doing the whole reset pin thing?

twin dew
#

Should be pretty easy if the one doing it has any soldering experience.
As there is solder resist, so you can even heat all the 4 legs on one side at same time when removing and reattaching the chip, and it shouldn't bridge between the legs.
Or when it first does from too much solder, just reheat and remove some of that until the bridges disappear.

#

Just need to watch to not overheat the chip to failure.

#

Like with any component.

mental oriole

#

And even getting replacement 555 should be trivial from any electronics component shop, which most cities have at least one.

How it feels to offboard someone

winged valley
#

My board only has 4 ram IC's (confirmed by the fact that the part number is for 32gbit or 4GB), but SIV reports that I have 8 running in Quad Channel

#

I don't think the 1260P (12500U according to SIV) supports quad channel, but anyways, assuming SIV is correct about everything, would that mean the IC's are dual-die and each one is running in its own channel?

#

I guess its not impossible but with only 315 balls per IC that seems a bit crazy to me (also I can't verify die count because Hynix makes it near impossible to get that info for some reason)

edgy hazel
languid gulch
#

this probably sounds dumb but i finally got a fine cleaning brush with long enough bristles to get down to the base plate of my keyboard, & it's just nice to not have to use my air compressor for that

twin dew
#

So the chip number is probably wrong, but each of the chips is probably own "channel".
For total of 128 bit memory bus like is standard.

#

Just that even for the techs with 32bit (sub)channels, in x86 PC space we still talk only about "legacy" 64bit channels.
So 128bit total is "two channels", when in reality with some of the current memory techs that is actually 4x32bit, not 2x64bit.

#

LPDDR has been there for long time, DDR5 took the normal DDR there too.

#

And the dies are probably dual-rank, which causes them to be detected as "two" dies.
As each rank is handled separately.

#

Causing them to be shown as 8 dies.

#

And software cannot AFAIK separate between 2x 1R and 1x 2R.

do you have g sync on your monitor?

twin dew
#

Goes up to about 500hz for some people.
To top up at only 60hz is very low bar.

twin dew
#

I have no idea how high I could see the difference.
I was talking that the best that been tested were in that range.
And most are significantly above 60hz, but not at 500hz.

#

So 144-240Hz monitors make sense, going above that 240hz not so much.

keen jackal
#

your eye at max strain sees 90 hZ

#

under stress

#

for most people*

twin dew
#

Based on what?
Human eye and vision isn't discrete thing but continous.

keen jackal
#

no its your brain

twin dew
#

There is minimum you can see as motion, and then max above which you don't notice short things anymore.

keen jackal
#

your eyes work like photos

#

takeing many photos at once like video

twin dew
#

No, human vision is very messy continous process.
Not discrete frames.

twin dew
#

Which is whole point why we can see video as being in motion when the frame rate is high enough.

keen jackal
sand saddle
twin dew
#

And after certain very high point, the additional frames don't bring any more benefit, but that bar depends on person and top 1% or so can notice single "wrong" frame at 500hz.

#

IIRC how it was tested.

#

And the bottom 1% was IIRC in the 100-200Hz range.

keen jackal

g sync adjusts monitor display rate to gpu output rate

On 144Hz monitor it would be 144, 72, 48 etc. FPS.

#

With 240Hz: 240, 120, 80 etc.

#

1:1, 1:2, 1:3 and so on.

#

G-sync is just first common implementation of variable refresh rate.

#

And actual HW G-sync has almost died away, and most of the "G-Sync" monitors are just adaptive sync with g-sync branding.

sand saddle
#

g sync is an implementation of v sync

sand saddle
twin dew
#

Without V-Sync the framebuffer (what frame is being actually drawn to monitor) is switched whenever there is newer frame available.
Leading to it being switched in mid-draw, causing visual issues.
With V-Sync the framebuffer is only switched between monitor refreshes.
Adaptive-sync (the base standard), Free-Sync (AMD branding) and G-sync compatible (Nvidia branding) work by having the monitor change the refresh interval dynamically based on when the monitor gets new data.

#

No, like the name says, Vertical Sync, framebuffer/frame switches are synced to the monitor.

#

But that makes it that it can only run in lockstep with the monitor, so max FPS is the refresh rate, and then any divisor from that, so 1:1, 1:2, 1:3 etc.
