What I found with my chip is:

200x18 @1.3V (stock volts) = ok.
200x18.5 @ 1.35V = ok.
200x19 @1.4V = ok.

So I needed 0.5V more per 100MHz step after 3.6GHz. (This was with all other voltages at stock, NB, CPU-NB, etc)

Good luck, hope your CPU unlocks to 4 cores and is a good clocker
Thanks for the reply Anarki. I've got 3 120's in my case so it will maybe hit 4Ghz I hope with decent temps then. Did you unlock yours? Did you try any FSB OC'ing with it or just multiplier?
