I searched around and couldnt find a straignt answer

What exactly is the CPU PLL Voltage

My P5K Premium has the option to put it from around 1.2 to 2.2 or something

its on auto for now but will increasing this increase my OC ability at all ? im on an e6850 at 4.0 right now and the only settings I have changed are

NB 1.25v
FSB 1.5v
SB 1.2v
Enabled the Damper
Disabled the Transbooster
