[h=2]Hello Guys

I wanted to Overclock my 6950 2gb from stock 800/1250 to 880/1375 or more, I swichted the BIOS now the Shaders Count is 1536 (6970) .

When ever I try to OC the card the screen starts to become unstable at Lower Core Speed, but when I run a stress test like that which comes with GPU-z screen is perfect.
Secondly I wanted to Tweak the voltage just over 1.100mv which is by default the max voltage, how can I change this ?? I have tried editing the registry and also the MSI AB config file...


Please help ![/h]
