I came across this page which concerned me a bit. http://www.overclock.net/t/1360404/asrock-z77-series-vcore-reading

Apparently the AsRock Z77 Extreme boards have a problem with severe under-reporting of Vcore voltages.

I'm trying to use an AsRock Z77 Pro4 for overclocking and am concerned it may have the same issues.

Has anyone here gotten the chance to test and verify whether the Pro4 boards have a similar Vcore inaccuracy issue?

Thanks! redface.gif
