Vcore shown as completely different in every program I try???

[singh_uk]

Hello

I have a Asus P5k Deluxe with a E6600 @ 3GHz.

I am trying to find out what my Vcore is from windows, but what ever program I use seems to give me completely different results. In the BIOS it is set to 1.3 and the BIOS monitor shows it correctly as just slightly below that.

However in Everest it comes up as fluctuating around 2.5v (!)
In CPU-Z as 1.264v
And in Coretemp as 1.35v

For what reason are these voltages fluctuating so much between different programs and how do I know which one is correct?

Thanks

The only true reading will be from a decent calibrated digital multi meter then see which software is nearest to that value.
