overclocking graphics card

[gamerxx13]

I just got an evga 8800 gts 512. I was wondering how exactly do I start overclocking it? what programs do i need, and how do I go and change the settings. I guess i cant do it with the nvidia drivers. Thanks!

Download it, then read the overclocking guides:

You could try atitool. It will stress your GPU to the max and determine max clocks. Of course you can also manually set clocks.
