And make sure your Ref Freq is 266, and mem freq is 533 so it stays 1:1 and wont hit DDR2 800 till 400fsb. Tune it from there, or what kind of OC are you looking for?
Looking for 400X9 mate. The best i've gone so far is
1.5 Vcore
1.4 vFsb
1.6 vMch
380X 9
Orthos fails in 19 mins though and my XP crashed
Ram ratios are 1:1 @ 266:533
