Go to your display properties and hit the nVidia tab. There you should see all kinds of options. Select the "clock frequency settings" and select "manual overclocking". It will pop up a disclaimer about overclocking might damage your card.. blah blah. Just agree and click ok. Then you will have a button that says "detect optimal frequencies". Just click that and it will find your optimal overclock. After it completes hit apply and there you have it. You can check the box that loads these settings on windows startup too. Hope this helps.

EDIT/// Oh ya if you have not installed the coolbits patch yet do so before you try any of the above. Just unzip coolbits somwhere and click on the file. It will patch your registry and open up the extra options.

The card in your Sig is a 6800GS and Optimal would be no were near 570/1.35...

If your getting some artifacts try lowering the memory speeds until the artifacting goes away. It might just be detecting too high.

I am at 505/1200 mhz and that is OCed from 445/1070. What card do you have? I have the eVGA 7800gt. And how can I get mine to go that fast?

OOPS NVM, I realized it said 7900GT. Wow I feel dumb.
