After testing my quad, I found the stable settings for 24/7.

8x400= 3.2Ghz
Vcore : 1.2925V (1.28V idle and load) Vdroop mod
PLL Voltage : 1.5V
FSB Termination : 1.2V
NB : 1.27V
SB : 1.050V

Not sure whether I should push higher since the VID of my Q6600 is 1.325V. Except NB voltage, all other voltages are running at stock or lowest setting. I'm not sure also whether to erase the Vdroop mod because I'm afraid of damage to the board or CPU. Any thoughts?
