Has anyone found a way to do this? I really dont want to mess with the pencil trick. Just wondering if anyone found a way to just raise the voltages through the BIOS for 7900GT.
 
I don't think so... I don't think it will ever work with that card.. it has to be a physical change on the card to move the voltages.

Thats what I thought. I know they have some "anti-overvoltage" mechnisim in the card so even if you do change it thru the BIOS it will change back. But just thought ill ask to see if anyone found any ways past it.

Oh wow.. I have been out of the loop for a while.. that's awesome.. I might be able to undo my vmod now and just run with a modded bios.. thx for the linkage. good things!

So even with this new voltage edit, you still need to do some soldering to the video card, correct?
 
The way i understand it is that you need to have the eVGA PCB rev tha has the voltage switching hardware installed ( as shown on the PCB ) if you have that lind of board then you can edit the volts via bios.. or maybe we can buy those resistors in local hardwares and solder it ourselves?

You can use any 7900GT board that has no extra hardware mounted like the EVGA SS.
You will have to solder the three components that are described, and you will have to enabe VID 1 in the BIOS for 3D, preferebly use the EVGA SS BIOS.
Go to the link in the 3rd posting in this thread and read carefully.
 
Id still go with the conductive ink mod as that soldering mod is hard to clean when RMA'ing

Buddy, you have no idea the can of worms you just opened...
