PLL - Phased-Locked Loop



This is my guess. Somewhere on that motherboard is a circuit that is trying to maintain a constant CPU voltage and this option allows us to adjust the voltage to that circuit. Any second opinions on that?
I would agree depending on the oc to get the voltage stable I have to use 1.6 or 1.7 pll voltage. I think the circuit is the regs under the top heatsink because when I use 1.7 pll voltage it heats up like crazy.
