Try 422 x 9 and see if you can get that prime stable!!
Thanks a lot K.I.T.T, your advice is well taken!
And you've given you advice at the perfect timing becouse I seems to be hitting a wall right now at ~3.7ghz. Maybe I should try the x9 multiplier cos I know I'm starting to get near the max stable FSB from the Q6600 G0 and P5k-Dlx combo at ~480ish.
