Alright here is my problem. I got a xfx HD6950 (1GB version), but when i play games like Crysis, Crysis: Warhead, and BF:BC2, the game crashes within a few seconds/minutes with the message "the display driver has stopped responding, and has successfully recovered." I had posted a thread a couple of days ago here: http://www.tomshardware.com/forum/forum2.php?config=tom...
Back then I thought it was either a faulty card or my PSU was not supplying enough power. I have tried rolling back to CCC version 11.4 and 11.5 (which is what I'm running now) and previously had 11.6 and have also tried underclocking. I have also tried changing the Timeout Detection and Recovery which I read about here: http://msdn.microsoft.com/en-us/windows/hardware/gg4873...
After all of that I contacted XFX about RMA'ing my card, but I'm still not convinced it is a faulty card or PSU at this point. I can play Metro 2033, TF2, NBA 2K11 and every other DirectX 9 game. If I force BF:BC2 or Crysis into DX9 mode, it will play flawlessly, albeit alot less pretty. I thought, maybe by playing in DX 9, it isn't stressing the card enough. So then I played Witcher 2 (Which I believe is a DX 9 game) with ubersampling enabled just to see if it would crash but it still chugged along (I wouldn't call it playable at 15-20 FPS though). Could it still be a hardware issue if its only DX10 that causes a problem? But I'm still kinda confused since it plays Metro 2033. The settings indicate that it is running in DX9 mode with some DX10 shaders enabled. I cant really find anything relevant about this problem through google, so I was hoping someone could point me in the right direction for a fix(I'm still waiting on a reply from XFX support).
Windows Vista 64 bit
6GB GSKILL Ram
1000w Kingwin PSU

EDIT: I forgot to mention I've checked for faulty memory through Windows Diagnostics tool and HWMontior is reporting a max temp of 77c under load which is normal for this card
