Yea all I did was follow your two step guide (and that smaller bit underneath about 75%). The reading came from CPU-Z, yep. Is this bad?
I've just looked in the BIOS and when I look at CPU Voltage, I can visibly see it fluctuating between 1.288, 1.296 and 1.304.
In windows the Vcore is at 1.488 (In AISuiteII and CPUZ).
PS I don't want to kill my CPU!
All the time I was successful with those simple settings.
When you set to 4.2 or 4.6, just go down a bit and you will see what the voltage applied will be. It's not in another screen where you read live values, it's just below the CPU Level Up option.
