GeForce 6 & 7 Series Voltage Soft-Mods

If your NVIDIA GeForce 6 or 7 series overclocking adventures haven't yielded the kind of results you had hoped, this guide on the AOA Forums may be of interest.  They outline the steps necessary to soft-mod the BIOS on many GeForce cards to increase the GPU's voltage using NiBiTor and nvFlash.  I've done this mod on a GeForce 7800 GT card with some success, but it's not going to work for everyone because some board partners already tweak their voltages to support increased clock speeds on factory overclocked cards.

"Over-clockers are always looking for a way to squeeze every last drop of performance out of their hardware. This has been going on for years. Today's Video Cards are great candidates for over-clocking. Many have high-end capabilities just waiting to be released. As any over-clocker knows, an increase in voltage can sometimes net a moderate to great increase in the overall over-clock, but there is no guarantee that this mod will offer any increase in your over-clock. With that in mind, we will be showing you how to perform a BIOS volt mod to your 6 or 7 series card."

Also keep in mind that anytime you increase the voltage being supplied to a component, its temperature is likely to increase.  If you soft-mod your card to increase your GPU's voltage, you may want to think about some additional cooling as well.
