I Need Help! With the specs in my sig, i can't overclock my x800xt at all. Even if i push it 10Mhz using ATI tool, I get patches of lines across my screen when 3dmark05 is ran or a game is played. It has an ATI silencer 4 on it, and temp is certainly not the issue. Do I need to up the voltage to the vpu? I dont understand why this is happening! Im seeing lots of people with huge success overclocking this card. I tried using omega drivers and they simply don't work with my system, they make windows navigation very slow and give me errors before i can even start up a game. I'm getting 3dmark05 scores of 5500-5650 with stock vpu speeds, and I know I can get well into the 6k's if I can get this card overclocked. Please Help!!
