HD 5850 and 6970 BSOD + Driver Stopped Responding.

GA p55 ud3
kingston 1333 2gbX2
Hd 5850 / 6970
Corsair TX 850
Intel i5 (750)
Windows 7 x64 Home
No overclocking.


This has been going for about 6 months. Got the 6970 a couple of days back. I can play games for hours with no problem, only once did it "crash" when playing a game, ME3 and that during a video at the end. Otherwise it happens when using browsing watching streams etc.


The behavior before bsod is the same as with stopped responding. When at this site the gpu has to work hard apparently, cc 500 MHz, mc 1375 MHz (peak).
When i get the stopped responding message, both core clock and memory clock jump to peak. 880 MHz and 1375MHz or rather moments before the message during the freeze and black screen. Speed jumps down to idle after it "responds" again as if it was a digital wave signal in a sense.




It started with display driver stopped responding message, and then bsods. (with HD 5850)
