Hey all :3 long time.
Cutting to the chase:
I purchased a HIS HD 7770 GHz edition upgrading from my S***ty last generation HD 6450.
Core speed is default at 1000MHz Mem is default at 1125Mhz.
If I increase sliders even a little bit (in AMD Overdrive (which has safe limits)) I get the error: Your Display Driver has stopped responding and recovered. This is when I'm not even gaming, just with a window open. Temps are fine at 26c...
