I just found out that I have not had the 4 pin connector 12v into my motherboard. Does this have to be plugged into my P4B266-C motherboard? Would that increase my chances of overclocking? Everything has been working fine though. I have my voltage running at 1.6.Maybe this could be the cause that I can't get past 2.2? If any of you guys know if I should have this little connector plugged in (looks like a square with 4 connectors let me know. For some reason I am guessing I should plug this in right away.
