7900 xtx and weird artifacts pixels

[N_L]

Here's a rundown of everything I've tried before and recently, in no particular order. If anyone has any idea what else to try let me know. I plan to keep trying new games until I find enough where it happens consistently and then I can send it back because all the stress and benchmarks are fine. If I send it now as is, they'll just run stress test, benchmark or game and say it works fine and send it back, and I'll be without gpu for weeks or months.




Tried integrated GPU and older GPU card I have (nvidia 1070) no artifacts

Tried HDMI 2.1 from PS5

Tried two different dpi cables and 2 HDMI cables

Tried 3 different monitors(or well 2 plus tv)

Installed fresh win11 without anything and tried there

Freshly installed various drivers

Underclocked

Overclocked

Tried all the stress tests and benchmarks I could find

I even recorded in-game footage and it shows these artifacts in the video

Tried different resolutions in-game and in Windows settings

Tried different refresh rates

Fixed card sagging

Expo (for RAM) is disabled in bios

I don't have another PCIe port to test, or I do but gpu can't fit there

Removed drivers through DDU between testings

No remaining PCIE cables from the PSU but no place to plug it in in PSU even if I had it

I switched cables around a bit inside between things

It might have worked in the end when I tried running it without any drivers but the game was so choppy and lagging I couldn't test more times and CPU was maxing so maybe it was running off it.

Installed the driver only from March 2023, for a moment I thought it worked but after a restart same old, not to say the restart made it worse it's just that it's not consistent.

I reinstalled the newest drivers

Overlock and underclock didn't help from either afterburner or amd software, same with some gaming profile t hat does things.

Can't run memory clock under 2500



As for the games, I haven't really been playing much but I did notice it originally in Honkai Star Rail, which is a mobile game and I thought oh it's flashy and unpolished maybe it's just the game and it wasn't much and at random places.

Later, ESO - older mmo it would show up a lot and in all different colours and places.

Wanted to play two mirror but noticed it right away in the menu, noticed it in the game too but it's a bit more discreet there.

Started playing kingdom come deliverence and it only shows in certain cutscenees and just in a black spot above the cutscene though I think it went down a few times as well.

I noticed it in discord as well but this might just be down to hardware acceleration there.

Warframe I just ran once to test and I could see it popping up here and there when paying attention to it.



Oh and this is how the card is powered, it's not dusty or dirty the camera just went into night mode and messed up the colors.

System specs? Is your PSU up to the task to feed this monster enough juice?

Please run a third PCIe 8-pin power cable from your power supply and refrain from daisy chaining any connectors on high-wattage GPUs such as this. It's not a good idea and it might very well be what's causing your issues under load.

I don't play Star Rail but I do play Genshin, and despite being a "mobile game", it can be quite demanding if you're pushing 4K+ with uncapped frame rates, and I believe Star Rail is just about the same.

 

[N_L]

Cant run 3rd, 2 are cpu and 2 pcie, only cable left i have is 16 pin one :/ im thinking of getting 15 pin to 2x8 pin cable now and seeing if that works? Also no space for 5th 8 pin on psu

 

[nguyen]

Looks like snow artifacts associated with too high OC, try positive voltage offset (higher voltage at given clocks)

 

[Noci]

Another thing you can check easily:

XFX cards do have a dual BIOS, did you check if it happens with both?

Why not? Most unusual that a 1200 W PSU doesn't have three 8 pin GPU cables. Can you double check that? My EVGA 1300 W supports six, currently using a cable that converts 3 PCIe outs into one 12VHPWR for my 4080 and it works just fine.

Noci's suggestion with the dual BIOS is of academic interest (see if the behavior or trigger patterns change), but unlikely to solve the problem

This is an ATX 3.0 PSU, with only 2 PCI-e connectors but an additional 16-pin 12VHPWR connector.
https://nzxt.com/product/c1200-gold

but if he uses only 1 8-pin EPS connector to the MB for the CPU (which is sufficient), then the second one can be used for an additional 8-pin PCI-e cable as far as I know.

Regarding the V-BIOS, you're right. It probably won't solve the problem, but excludes the rare possibility of a corrupted BIOS.

Excluding possible culprits, narrows down on pin pointing the actual problem..

The only time I had artifacts myself, was way back in time when I oc-ed my VRAM a little too much.

It's understandable that it's meant for 12VHPWR natively, but it is still a very high capacity unit... should be expected that one would try to run a 3x 8-pin GPU off it. BTW, EPS can't be reused for PCIe. They look similar, but they aren't electrically compatible.

Yeah they're keyed differently.

Have you ever check VRAM temperature? And/or any GPU operating conditions?

 

[N_L]

Thanks for the advice everyone, im on a trip until Wednesday and Ill update you with everything I try when Im back.

 

[Noci]

Yeah they're keyed differently.

Only on the user side (MB/GPU). On the supply side (PSU) they're the same. So with an extra original PCI-e cable he can feed some power to his 7900XTX.

 

[ahujet]

Looks like faulty/unstable VRAM.

 

[Vya Domus]

Defective VRAM.

I plan to keep trying new games until I find enough where it happens consistently and then I can send it back because all the stress and benchmarks are fine. If I send it now as is, they'll just run stress test, benchmark or game and say it works fine and send it back, and I'll be without gpu for weeks or months.

I think you are wasting your time, RMA as soon as possible. If you get unlucky and they send it back it's not gonna matter how consistently you can replicate it.

I did when I oced, I'll try again tomorrow, just realized what time it is..

Another thing you can check easily:

XFX cards do have a dual BIOS, did you check if it happens with both?

One of the first things I tried when I googled solutions and found out about dual bios :/ didn't change anything

What noci said, it's unfortunate but I am trying to get another cable to test it with but it's gonna be a while.

Will do this tomorrow first thing, just a reminder to myself.

Defective VRAM.

I will, they already refused me once until I showed it and then offered to send it up the chain but I kinda want more evidence in more games so if they refuse I can get a lawyers (I know...) to write a threatening letter and hopefully they take it seriously. Annoying how these things are here sigh.

 

[N_L]

Did a few tests, overclocked, underclocked, voltage up, voltage down in CP2077, and monitored my temp, here are the pics, the game ran fine, fully maxed settings and the pic was while in "rage" mode which is and adrenaline oc, ~45-50 fps. didn't notice anything out of the ordinary though the game is flashy and maybe if I played it for few hours something might have popped up.
First pic is while running haven for a while and 2nd cp2077.

 

[N_L]

Just an update, recently got my warranty claim fulfilled and got a new card, no issues whatsoever like before! On one hand I'm so pleased but on other it sucks I had to do all this research to be sure (and not even 100%) they'll accept it in the end but oh well
