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.

You will need a few things before we get started.

  1. Download a copy of NiBiTor from  NiBiTor can also be found at AOAFiles. I used version 2.9a for this guide. (See appendix for a complete list of applicable video cards)
  2. Download nvflash version 5.13. This can be found at AOAFiles.
  3. Last and most important, you will need a FX 6 series or 7 series graphics card.

Before we begin, check your cards temps at idle and under load. This will give you a base point and tell you later if we have any trouble.  Also make sure your card is not over-clocked.
