I just built and OCed my new system, but I am noticing a troubling thing regarding the CPU core voltage. Note that this occurs both when my computer is overclocked and when it is not:
The CPU core voltage always reads higher than the default value (1.3V) which it is set to. For example, at idle, CPU-Z usually displays 1.360V - 1.367V, while EasyTune5 Pro displays 1.390V - 1.400V. Under heavy load, CPU-Z displays a core voltage of 1.424V, and EasyTune5 Pro displays 1.45V!
My questions are as follows:
(1) Why is Vcore higher than 1.3V (at which it is set) at idle?
(2) I do not know whether or not Vcore is supposed to vary with load -- is this "voltage throttling" intended? If so, is it acceptable to go as high as 1.45V under load?
