    How do you volt mod a card by editing your BIOS? Can someone do it for me? My BIOS file is located here:
    http://www.freewebs.com/desalbum/6800BIOS.ROM

    A little info about my card:
    It is a geforce 6800nu pci-e from Dell 256mb
    Not supported by Nibitor

    I want to increase the voltage by 0.1v. Thx.

    If my reading and comprehension skills are up to par, you can only bios mod up to what the card supports and your GPU is probably already maxed on voltage out when it is in 3D mode.

    Maybe it is different for 6800's, but my 5900xt can give me no more voltage, without some soldering being done.

    As I said, using nibitor is totally hopeless. It is not supported.

    Umm, yes it is:

    You need the latest version of nibitor

    NiBiTor v2.0a

    Since it is the GPU volts that desdick wants to change, if you check the NiBiTor v2a Voltages tab you will see that it does not allow for that function ?

    And looking at his BIOS with a hex editor, it appears that the GPU volts lookup table is not actually enabled. Which doesn't make a lot of sense, but does indicate why NiBiTor can't read GPU volts.

    Yup. Voltages cannot be changed. Can someone change it for me?

    What is your reason for wanting to have it done? You will not see much of a difference in games (the only reason to have it done in the first place......on the other hand, if you want to watch your 3dmarks increase like crazy..........)

    I only scored 4896 for 3dmark05 and I thought it would help.

    That may not be a low score for that card. Drivers offer score increases. What driver are you using? and what is the temp? Adding to the voltage will increase the temp.

    Your link took me to your login page.

    opened your bios with 2 different editors and they won,t allow me to adjust volts.Do you plan on oc,ing this card??
    i changed my GT from 1.3 to 1.4 to achieve a stable OC which worked for me,the bios has a 1.4 3d option but there was no gain at default clocks,don,t worry about the stupid benchmarks just play the games and have fun:p

    I'm using the 71.84 drivers. I'm going to correct the links.
