Bios volt mod 8800 GTX?

[Xenozx]

I have 2 8800 GTX's, and when I look in Everest, it lists them at different voltages.

I want to get them both to the 1.4 (1 is listed at 1.3 and the other at 1.4)

Obviously they are the same card (one is black PCB the other is green) so the only real difference must be the bios. I have been reading about a program called

Nibitor

and I know you can flash bios's and stuff. Would it be safe for me to take the bios off my one card and put it on the other as well? Does it matter if the ram chips are different? Like if one uses samsung ram and the other hynix?

Just currious. I cant get a definitive answer on if volt moding can be done via Nibitor or not. WHAT IS THE VOLTAGE TABLE EDITOR in Nibitor?

also, I noticed this bios and it says 1.47 volts, does that mean this bios is set to 1.47?

Yeah, there's no problem if you flash the other with the overvolted one bios.
I have already flashed my 8800gts 640m with a 8800gts640m KOASC, 8800GTX, 8800GTX SC, and 8800 Ultra BIOS and I have never had any problem with it.
Take a look at here, there's good information about it. http://www.mvktech.net/

There is no BIOS voltmod for the G80 boards, at least none that I am aware of. Any voltage changes to the GPU or memory must be done via hardware modification.

Some of the G92 boards have very limited GPU voltmod ability in the BIOS, for instance the 8800GT can be bumped from 1.05v to 1.1v (a .05v increase) via a simple BIOS alteration. NiBiTor will allow you to do this.

NiBiTor always gave me voltmod options with my G80. But the increase of volt never gave me a significant improvement in overclocking, so I don't know for sure if does it really work.

NiBiTor gives lots of options that do not necessarily do anything depending on the card you have. While it's true you can change the values for vGPU in NiBiTor on the G80 boards it would have no effect since the voltage is hardwired.

There are some fairly easy hardware voltmods for the G80 boards out there, just make sure you have adequate cooling before you undertake such a venture.
