RX 6700XT VRAM ISSUE

[Yashpashar]

For the past week or so my PC had been crashing constantly during games. I wouldn't get a BSOD, it would just go straight to a black screen, sometimes immediately restarting, sometimes staying on with a black screen until I manually power cycled it. Windows event viewer also never showed any errors.

 

I've run a bunch of tests and I seem to have figured out how to replicate it:

8 hours of Memtest86 showed no errors.

1 hour of Prime95 Passed.

1 hour of OCCT Power Test passed.

1 hour of OCCT GPU test and multiple runs of Superposition all passed.

~10 minutes of OCCT VRAM test replicates the same crash.

 

So I'm guessing it's pretty safe to assume that my 6700XT has a couple bits in the VRAM that are acting up. Now what I'd do next is trying to underclock my VRAM, except Adrenalin has a lower limit of 100% (2000 MHZ) set on my clock, and I also see no way of me increasing my VRAM voltage to try to increase stability. I'm at a loss on how I'd go about fixing this issue. Unfortunately my financial situation doesn't really allow me to buy a new GPU at the moment. 

 

Specs:

Ryzen 5 3600

RX6700 XT

ASRock B450M PRO4

CoolerMaster 850W Gold V2

 

TLDR: VRAM is unstable. Can't underclock or increase voltage to fix. Help!

Just to verify, can you test with this?

Sick piece of software! Had never heard of this. A bit of an update from when originally posted. I tried updating my AMD chipset drivers and that somehow got me to pass and hour long OCCT VRAM test. Not sure how the chipset drivers would've fixed the issues but I'm not complaining. 

 

I've been running memtest Vulkan for about 15 minutes now and all has been well. I'll probably run it for another hour and a half just to be sure though. I'll also have to test playing actual games since that's where the crashes are most consistent. Will report back with whether or not I start experiencing crashes again.

Solved.

 

After running my PC for 2 days without crashing I'm pretty confident that updating my AMD chipset drivers was the solution.
