Folding Forum

Hello there, in the last couple months I've been experiencing seemingly random black screens that could be resolved by switching ports on the GPU (it has 3 Displayports).
A web search said it could be a sign of a failing GPU, but also driver issues, PSU issues, cable issues... lots of things. Haven't seen any artifacts, so I didn't give it much thought, undervolted my GPU to stress it less and moved on.

Now, more issues happened:
- my desktop wallpaper disappeared (turned black) - fixed it with a reboot
- my desktop icons turned bigger and their background turned black when hovered with mouse - fixed with a reboot
- my desktop icons turned bigger again with black background - this time the reboot only fixed the background, icons remained large

I'm on Ryzen 7 7700, 32gb DDR5 ram, AMD RX 6700. Windows 11 IoT LTSC. Been folding on this GPU since March.

I'll be trying to rule out software issues by updating to latest update available for Windows 11, i.e.: 24H2 x64 (KB5070773) (26100.6901).
Then, in case it'll persist, I'll uninstall GPU drivers with DDU and reinstall them.

I'm worried I could damage my GPU (or accelerate its failure) but I don't want to stop Folding unless necessary.

Any advice?

PS: I just seem to have solved another issue, don't know if that's related: viewtopic.php?t=43277

Your system and windows is broken.
Reinstall windows first. Then see what else is breaking

By reinstall you mean a clean reinstall - formatting and installing windows anew? It's my daily pc so I'd avoid it unless necessary

Yes, because it seems your install has been corrupted to the point of no return
The combination of your issues is pointing to broken OS. If your system continues to behave similar with fresh OS, then your hardware is dying

It could be failing system RAM too ... did you run a few Memtest86+ passes to check it ?

No, I didn't. I'll do now.

Do you suggest other tests?

Y-cruncher

Memtest86 failed 1 of 48 tests, with 2 errors. Is my RAM bad? And what do you suggest doing now?
I purchased all the components of this PC last March...

Double check if RAM voltage is actually 1.35V instead of 1.1V stated in few places in your post. Once you set it to 1.35V manually, observe if the voltage really holds up, even in BIOS you should be seeing the voltage. If it is shows a bit lower than 1.35V, add the difference, and save. Then run Memtest again

I first tested if it was an Expo issue, set Expo 2 instead of Expo 1 and Memtest this time passed. Guess RAM is fine, but unstable on Expo 1?

Should I run Y-cruncher now?

I don't see EXPO 2 profile in your comment. What does it have different from EXPO 1?

If EXPO Profile 1 is 6000MT/s 30-36-36-76 1.35V; Expo 2 is 5600 MT/s CL36-38-38 (if I recall correctly). They're the two standard RAM overclock profiles, usually you'd use EXPO 1, but mine apparently is unstable, or there's some voltage problem with the pre-made profile, as you saw. Instead of tweaking it manually, I just selected the other pre-made profile on my motherboard, which is a bit lighter and more stable (I guess).

Also just tried OCCT, a 15 mins GPU Variable test and a 15 mins VRAM test showed no errors.

Maybe it was all related to the RAM instability? I can do some more test, just to be sure.

Stability is key for folding, but often a couple memory errors won't cause problems either.

I had some memory with major issues at one point, and never got any video or folding instability at all. But if your video display issues go away, you might have found an answer. But I would suspect problems with the GPU first.

Run through several hours of y-cruncher stress test on that xmp2 profile. If it passes, run memtest86+ overnight to confirm the stability

Thanks. I'll run Y-cruncher, but I'm more worried if my GPU has some underlying issue that could make it fail with Folding. Any way to test that?
