Yeah, leave it off until you need it to boot.

This setting helps when you hit the point to where it will not post? I can't seem to post above 4.8 with my 3820 but I haven't tried going over 1.4v or raising pll voltage over 1.811v

Yeah, it will help post when you cant, it will usually allow you to go 4-5 more multipliers above the no post. Example if you stop at 4.8 use it and you will hit 5.2/5.3 probably.

Hey dude, I enabled it and left the cpu pll on auto hahahaha, and i know what you mean, it juiced my voltage up and got my temps in the 90s after about 12 hours of prime 95. Eventually the pc just shut off randomly. Some one suggested changing it from auto to just under 1.7v so i changed it to 1.685, would this be okay? you said change it to .004-.020... I didnt see an offset voltage on this setting... how would I do that?

He's talking about the CPU Offset Voltage.  If it is left on Auto when overclocking, then it will raise the voltage up way higher than it needs to be.

I don't know.  I would leave it on Auto and ask others who own the ASRock Z77 Extreme 6 what their findings might have been if they experimented.

 

(the thread we are in right now is talking about Internal PLL Overvoltage)

Phase Locked Loop is a control system which acts as a comparator with phases (waves). It compares it's input wave with it's output wave and adjusts them so that both waves match each other.
Used in Computer Clock Synchronization. Can vary frequencies.
