How to overclock my 8800gt in Vista x64?

[YorkieBen]

Ive just put a new system together with a Leadtek 8800GT 512MB and would like to see how it overclocks, however I used coolbits on my previous PC and it doesnt seem to work in Vista x64.

I've downloaded Rivatuner but cant seem to find any overclocking settings, can anyone help/suggest alternative programs. I have a P35 chipset, would this prevent me using ntune to overclock my graphics card?

you'll have to run most utils as admin, also you may find some apps will need you to turn off driver signing. Personally I use Asus SmartDoctor pretty handy, had it working fine on my evga 8800gts.
