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.

Marco's interest in computing and technology dates all the way back to his early childhood. Even before being exposed to the Commodore P.E.T. and later the Commodore 64 in the early ‘80s, he was interested in electricity and electronics, and he still has the modded AFX cars and shop-worn soldering irons to prove it. Once he got his hands on his own Commodore 64, however, computing became Marco's passion. Throughout his academic and professional lives, Marco has worked with virtually every major platform from the TRS-80 and Amiga, to today's high end, multi-core servers. Over the years, he has worked in many fields related to technology and computing, including system design, assembly and sales, professional quality assurance testing, and technical writing. In addition to being the Managing Editor here at HotHardware for close to 15 years, Marco is also a freelance writer whose work has been published in a number of PC and technology related print publications and he is a regular fixture on HotHardware’s own Two and a Half Geeks webcast. - Contact: marco(at)hothardware(dot)com
