do it in your bios the i\o voltage default setting is usally 3.40v i have mine at 3.50 i dont recommend going above that you can do 3.60 but i would not push it thats even if your motherboard would allow you to go higher mine wont 3.60 is the limit.
For one, I cannot change the 3.3 in my BIOS. No option for it. For two, G3's run on 2.5v, different from G2's. I was wondering, is there a prc file for WPCREDIT for a GeForce line? I can't seem to find one at all. I also want one for the AMD761 chipset as well.
