i was just wondering how acurate are the core volatge temps on cpu-z , cause i was doing a 4.2 overclock on my i5 3570k and the voltage on the program was 1.3 on full load , just want to know what is stable?

I have completely no experience with the intel cpus and its voltages, But I do know a compensated VDROOP when I see it.

On full load it pulls more AMPS, then the voltages decrease drasticly. Your motherboard is overcompensating it by pushing out more volts.

But I have no idea what the optimal voltage is. Do bear in mind that the voltage could be perfectly normal for keeping the overclock stable. I simply have no experience with it.

alright thanks for the help anyway :)
