well that may be hard because for me I have 3 different voltages for vcore .. there is BIOS, cpuz idle and then cpuz load.
bios shows like 1.28v cpuz 1.26v and for load 1.23v

So, still bios and cpuz load?

Also, I was thinking would it be important to put QPI/VTT voltage on that spreadsheet? because that is a major overclocking determining factor too in some cases...
