Core voltage idle and load

[dantheton]

Hey guys I have a question about my my cpu core voltages when its on load and idle.

I am using a 3570k at 4.5 ghz at .065 offset.

Under load the voltages on cpuz are at 1.272 and my voltages at idle are 1.312.

Since it is on load why is the voltages higher on load?

By default to keep the processors running within tdp there is vdroop which adjusts the voltage depending on the processor load. Motherboards have a feature called LLC (load line calibration) to help offset vdroop. You should maybe give the guide below a read for a more in depth look at this stuff.
