A reference (Gigabyte) card I sold about 6 months ago to a friend of mine just randomly died.
Poor guy was playing some BF4 and then some Euro Truck Simulator when his PC froze up.
He rebooted it and the image on one screen was gone (dual screen). Wouldn't come out of stand-by.
The second screen had image, but only on 640x480 and 8 bit like messed up colors.
After cleaning the card and re-pasting it just to be sure I put it in his brothers PC.
Card works ''fine'' without drivers, but as soon as you install drivers and reboot the image is all messed up again with the same 640x480 res and 8bit distorted colors.
Card was running skyn3t's Rev 3 BIOS with 1.212v and always ran on the following settings: 1.212v with LLC still in place, so ~1.18v load, 1202Mhz core, 1750Mhz VRAM (Hynix R0C) and stock power and temp limits. Had a custom. higher speed, fan profile which never let it get above 65c load in-game. Guy has a noisy room as both his brothers game in there as well so the ~80% fanspeed didn't bother him.
Card was running just fine when it happened. Normal temps (second screen with MSI AB monitoring), normal clocks, normal fanspeeds. No artifacts prior to the crash, no crashes prior to this one.
Card has been run in my PC and his combined for over 8 months and never gave a single hitch.
Problem is, I modified it by sanding the LED logo to make it white, and I applied a ColdZero backplate and EVGA GTX680/GTX780 High flow bracket. It also has no shop warranty anymore so the only place I can possibly do anything is Gigabyte but I doubt they'll accept a heavily modded card like that. And I would totally understand them as well.
So, do you guys have any idea what the problem is or whether it's fixable? Card can still be flashed and is usable in safe-mode. There's also no physical damage to the card. No blown VRM's, no damaged VRAM chips, no nothing...
