Help Overclocking Q6600 with P5N72-T

Alright, I stabilized my Q6600 at 3GHz but I changed nothing but the FSB, I have no idea what I am doing with this board.

I had a Gigabyte 650i before but I was overclocking a dual so I didn't have to increase much but the vCore and I was good to go.

This Quad has be baffled, I have no idea what to set the PLL or VTT, what to do with the GTL reference, if someone could give me a rundown of what they do as well as where they should be I would be grateful.

The Q6600 has a VID of 1.275 so it is a good chip and I have it stable right now at 333x9 at 1.26v but I don't know what to do with the other voltages
