passion stomper,
Is it your intention to push your system to the bleeding edege?
If so then you have to keep manipulating the voltage, fsb and multiplyer untill it is obvious that youre not gonna remain stable.
General rule with nforce2 boards and gigabytes philophsy on overclocking is to lower multiplyer and raise fsb.
Personally I would let the system settle in or burn in at the most stable speed for abit and then proceed from there.
My xp1700 has been at 11x200 1.85v for a couple of months now, and soon I will attempt to gradually raise the fsb.
