Change dpm7 value0 in voltage table 2 to the voltage you want in mV.So I know I am a bit late to this thread but was hoping someone could answer my question. Is there a limit to how much voltage you can edit in the BIOS, because I have the voltage slider in afterburner maxed out and the card tops out at 58-60C and was thinking about giving it 1.25v or something is there any tips on how to go about this? Only other GPU I modified was my pair of GTX 660's and they are a little different from this in terms of editing.
That's about as far as I can get without artifacting or crashing, I know the memory is surprisingly high but I feel the core clock is lacking.
I think the max safe voltage is 1.35v, but you probably won't get much more frequency.
