Intel Pentium 4 3.00Ghz Cedar Mill overclocking

You may try. If your board BIOS has settings to increase the FSB, RAM divider/strap settings, and voltage adjustment settings for the CPU (and maybe the RAM).

As you increase the CPU speed and voltage, watch your CPU temps closely - those CPUs run pretty hot without overclocking. You may need a larger CPUheatsink and fan, and another 120mm fan. I would put 1 120mm fan intake on lower front of case, and the other 120mm fan exhausting heat from top back of the case .

that cpu i think it has a 80C TM point so watch the temp closely if your system can let you OC

another advice try take off your case side panel and lay your computer sideways to start off your oc.because your current case fan might not do the cooling properly.

If you board will allow faster fsb go for it but dont go crazy with the stock heatsink...
