Your thinking of the method suggested on www.tomshardware.com where you use nail polish or teflon tape to cover up a pin on the slot1 celeron to force the motherboard to think the signal is low, thereby allowing it to go to 100 mhz. see the page reference above for more information. It would be a lot simpler to find a good home with someone who is not interested in overclocking for your present board, and buy a good overclocker's model.
