OMG you're completely clueless. First of all, ALL Celerons have a multiplier lock. You can only increase the bus speed.
Looking at your OLD Celeron, it had the Mendicino core which was known to overclock in the range of 500-600MHz top, depending on the processor itself. Now, the 300A version could go to 450MHz at 100Mhz FSB easily. The 333A could go to 500MHz at 100MHz FSB easily. The 366A could sometimes go to 550MHz at 100MHz bus. It really depended on the quality of the specific processor, but ALL were limited below 600MHz!
OK, now looking at the Coppermine. It wouldn't go very much above 1.1GHz. In fact, the PIII 1.13GHz Coppermine was recalled because of data errors. So 1.10GHz was about the best Intel could get from it. You might get 1.2GHz, maybe a bit more. It's a BAD choice for overclocking.
Your BEST choice for overclocking is the 1.1GHz with 256k. That Celeron uses the Tualatin core, which clocks MUCH higher. The 1.1GHz Tualatin can EASILY hit 1466MHz at 133MHz bus.
And now you're thinking "those don't work on my board" and of course your wrong. You'd want to purchase a Tualatin adapter with adjustable voltage controll, the BEST choice being the Upgradeware Slot-T. It cost $20 here in the U.S. and you can find a distributor list at <A HREF="http://www.upgradeware.com" target="_new">http://www.upgradeware.com</A>
