can someone tell me how to overclock a 3.0 ghz Prescott P4 socket 478? and what to overclock it to?

First off, Teach yourself.

By that i mean look at the type of forums that exsist here such as windowsXP, PDAs, Linux and "OVERCLOCKING".

Once you have found the right forum for your question dont just start asking a vague question. Look through other posts first, because chances are SEVERAL other people have asked the same question or atleast something similar. Once you have done those things and you still need help, feel free to post an INFO FILLED question and im sure some one will be happy to help you as best they can.
