I'm getting stucked at this clocking Its a Connect3d x1950pro with AC accelero cooler. Stock 600core/700mem. Tried using both Atitools 2.6 and 2.72 beta. Tried pushing core to 685mhz no problem......ran 3dmark05 alright. Pressed set default and gfx lockups. Rebooted PC and tried pushing mem freq.......just +0.5mhz only and apply. The gfx just locks up. Using Catalys driver 7.8 now. Anyone can help if anything i could do to push my mem freq? Btw temperature is 47deg at idle at stock clocks. Tried running 3dmark05 with core at 685mhz and temp = 61 at load.
