I just enable my CPU Offset <increase 200mV>in Advanced Voltage and find out it can now run at lower vcore for higher speed. However, in CPU-Z and Asus Probe, it show increased vcore and temperature. I am wondering what is that function for?

I used to get vcore 1.435v and cpu-z would show 1.488v. Now, my 1.435v show 1.568v in cpu-z. However, I am reaching a good 3.304Ghz with it. Not sure if it stable but showing better signs than before. So, guys, do you have this option in your BIOS and do you enable it?
