Evga Voltage Tuner

Anxious to see new instructions!

But, why back up the BIOS? Does this actually modify the BIOS or something?

It should write to VT1140 I2C address space and modify the register/s responsible for setting the main VR output voltage. If you can read the voltage through I2C, and its not a read only register you can definitely write it no problems.

Goldentiger,

Sounds like you wrote up a simple little C++/ASM function to handle the voltage adjustments? If so cool mate Does changing the register affect all Performance Level voltages or just 3D Perf? Had a quick look over the VT1103 plugin source and looks like it wouldn't be hard at all to write a little tool to do it. I think I got the gist of the registers, 0x19 looks like it holds performance level value, 0x1c looks like the money man
