Anyone have a link to a site that explains how to volt mod the 7800GTX? It isnt the same as the 7800GT is it?

Will a 7800GTX 256mb work if it is flashed to a 512mb with the speeds set to 256mb speeds? That is the only way i can get more volts w/o a mod. I dont know how much 1.4 to 1.45 will do but ya..... Any other links with clearer instructions?

No, the 512MB GTX uses a different PCB and different RAM. Just use a BIOS editor to change the voltages and clock speeds (good luck getting 512MB GTX clock speeds) of a copy of your current BIOS, then flash it.

Yeah, apparently in reading that thread on XS, you can't overvolt through software means. Well, hope you're really good with a soldering iron.

You can get all the things you need for the mod at your local Radioshack.

Use a variable resistor, so you're not stuck with 1 voltage.
