cpu-nb voltage is what you want when oc'ing the nb. 1.55v max, just like cpu
CPU-NB VDD allows you to go over the rated voltage (1.55v), which i wouldn't recommend

Careful.

3.0 is best kept to golden chips and x6 chips.

2.8 is pretty much the max you'll get on Denebs, try to keep voltage below 1.45v, I never saw any real gains going past that much voltage, and it should be enough to hit 2.8GHz on your chip.

Yea, I can do 2.8 @ 1.31, but 3.0 take a lot more voltage.

3200 NB would be great if you could keep the temps down. NB waterblock.
