Vcore question

Last response: in Overclocking

I have a question about my Vcore.

I have set the voltage in the BIOS to be 1.387v. However when idle, CPUz says the vCore is 1.360v and when at full load CPUz says the vCore is 1.296v. Why is this?

Am I right in thinking that the difference between the BIOS reading and CPUz when idle is the vOffset (the difference between what you set and what you get) and the difference between load and idle is vDroop (reduction in voltage to keep CPU within its TDP)?

Can I trust CPUz's readings?

All I can tell you is it is normal.

Was worried that I was setting my Vcore too high in the BIOS because it wasn't hight enough in CPUz.

Reading up on how Vdroop and how the VRM works will help you understand this phenomena. Granted this page was written up fro the 45nm Core 2 series but the basic principles still apply (as far I know, no one has made a magic VRM yet).
