Actually i underclocked my GTX 480 from 756 / 950 to 700 / 924 (like normal gtx 480). After 1 or 2 minutes of running furmark (about 10 seconds without underclocking) my system reboots immediately (no blue screens or anything else), GTX 480 temperature reaches 75C. At first it looks like there is not enough power, but i got power calculator connected and it shows 406 W maximum (so i still got 200+ from chieftec). Has anyone else got the same problem? I should mention that such problem exists only when running furmark, Crysis Warhead at max details in 1680x1050 resoulution is fully stable, the same in Mafia 2. Is it possible that there is a bug in Furmark itself?
