Dude, you would probly get more help in the overclocking help section with this question.

I'm no expert but from what i understand if you clock with the cpu, you'll be overclocking your pci bus, but if you set it to 33mhz (pci default clock) you'll NOT overclock the bus, more than likely keeping it at 33mhz will increase your stability during overclocking because it may fail before the rest of your system. when overclocking your max overclock is set at your weakest part, and since your not going to gain any noticable impovment overclocking a pci bus, its best just to eliminate the possible weakness before you start by locking it at default. same goes with your pcix and your ram, set everything at default, then ramp your processor to its max, then ramp up your ram to its max, then pcix if you like too, though i keep mine default (mostly because i see no noticable benifit to overclocking the pcix bus) hope this post doesnt come too late.
