Hi, so I picked up an Asus Strix 1080Ti sold as faulty. The card hadn't been opened before. I thoroughly cleaned it (very dusty) and replaced the thermal paste (which was in poor condition). But this didn't fix the issues whatsoever.
Fans work perfectly, it boots into Windows perfectly, it does everything fine until put under load. Then it artifacts (colourful mostly blue star shapes) and crashes the program, or occasionally the whole PC.
I've played around extensively with Afterburner, and it is far more stable with the maximum -500Mhz memory clock and -400Mhz core clock. This allows 10-15 mins of use before a crash (but no artifacts).
So my best guess here is faulty VRAM. Is there any combination of undervolting/overvolting/underclocking that could fix this other than I've already tried? Any ideas on if this can be fixed?
EDIT: forgot to add that temps are absolutely optimal. Also the thermal pads on the VRAM and VRMs are in good condition.
