For quite a while now, I've had my 5770 overclocked to 940/1350. I saw crashes at 955/1390 so I thought it was a safe spot to keep it at. I've played many games, including crysis and metro 2033 which put my video card to 99% and haven't run into any problems with these settings. I started to play the game red faction guerrilla, and after a few minutes of playing, the game always crashes with a message that the display driver malfunctioned. Lowering it to 930/1340 gets rid of the crash, though it still stutters at parts, and at stock levels its fine. So I'm wondering, what makes certain games crash at higher settings and others dont, if both run at 99% video card usage? And should I lower my overclock settings just to be safe from possible crashes?
