Solved: See here for the solution. __________________________________ I'd like to try a little voltage mod on my CPU, I'd like to know how much further I can push this CPU. Does anybody now the maximum standard voltage which an i7 720QM or a 920xm uses? I just looked at some Intel datasheets, and I only found the "absolute maximum rating" for the VCC (core voltage) which is 1.45V. I guess the actual max voltage has to be distinctly lower, but I'm not sure. The VID table goes up to 1.5V. Some of the old Core Duo had a VCC of about 1.125V at their maximum multi (if my source is correct), and the "absolute maximum rating" was 1.6V (assuming I didn't make a mistake while looking this up) Without knowing the max voltage the CPU uses it's gonna be hard to do more or less sane mod. Any information would be appreciated. Edit: @unclewebb , as far as I remember you don't know a way to manipulate the voltage per software... (and I haven't seen any hint about how to do this in the Intel documents I've read so far), but do you know of a method to read out the core voltage of the first gen i7? Knowing the state of the 7 VID bits would allow to read out the voltage.
