what is cpu dll volts? there is a seperate line for this several items below cpu volts for the p5k line of mobo bios

I'm sure you mean CPU PLL... CPU Phase Locked Loop... Basically the clock generator on the CPU.. Take care with this setting for prolonged use, as it will cause as much damage as too high a vcore in the end, you may want to keep it around 1.6v for day to day use. I take mine higher but its only for short benchmark runs, a higher CPU PLL may allow you to get a bit more FSB out of the CPU but its only worth it if your chasing Superpi or 3dmarks. If you dont want to risk damage keep this setting as low as you can to achieve a stable OverClock.
