8800GT voltage mods

[JKDC]

Which resistor would I want to use for 1.25V? Is it something that I could go and pick up right now from radio shack?

Thanks for the help!

It should be at Radio Shack. You can check online availability before you go there from the website. It costs $2.69, look up "potentiometer" VR search won't find it.

I preset mine at 530 ohms before having an electrical engineer do it for me. Yeah I cheated. He had a pair of magnifying goggles so it was easy. I had him put it at the top of the card and run wires to the solder points so it is easy to adjust while in the case. Preset it with a dmm before having it soldered. 530 ohms gave me 1.16 volts. Just adjust from there...turn 1/8 turn and recheck and repeat and artifact check/check temps until you get where you want it. If you set it up like the pictures it should be counterclockwise for higher voltage/less resistance and clockwise for lower voltage/higher resistance.
