over clocking
How exactly do you over clock a PC?
I don't need to over clock mine, no need to with a 2 ghz and 1 gb of ram...But never understood how to do it. I guess it'* just a random question.

Well I think that HP/Compaq locked me out of those settings....prolly a good thing.

Often a CPU is rated to run at a certain frequency but can actually run higher. If you think about it, a CPU has to meet the minimum spec and it does so within a tolerance. So by overclocking you are taking advantage of that tolerance.
Often if you increase the voltage you can more easily overclock a CPU. I'm not 100% why (any EE'* out there?) Guessing it has something to do with minimizing propogation delay, perhaps takes care of some parasitic effects.
Edit: and yes, you can do this in the BIOS, or on some machines by moving jumpers. Probably would have better luck changing the multiplier than the bus speed, because if you change the multiplier, that will put tighter requirements on your RAM as well.

To your edit....
I just put in 1 gb of RAM last night....and barely using 200 of it....so I don't think the tighter requirements would bother it too much.

It wouldn't take up "more RAM" to run it faster. It'* purely a change in hardware functionality, not software. A software change would require "more memory"

In the "old days", cpu manufactures would run their dies at clock speed higher than their rating. If they worked reliably, they would get stamped at the higher speed and sold for more money. Ones that had to run slower were stamped at a slower speed and discounted. Same core, but some could handle to increased clock speed. They pretty much don't do that anymore.
My old 1.6A P4 has been running at 2.13Gz for 3 years and hasn't skipped a beat. After the 1.6 and 1.8A'*, Intel locked the multiplier internally so this trick didn't work anymore. The fastest way is just bump up the FSB to whatever they system will handle reliably.
You can't on the Compaq, they don't put the adjustments in the bios, and there are no jumpers on the boards
