Overclocking is when you increase the clock speed of the processor (or rather the board that the processor is plugged into) to make it run faster. Used to be just main CPU's but now includes graphics processors and any other processor you might have in your PC. Used to be fairly risky (as you're pushing the processor past it's safe tested running limits) although there are a number of built in apps with motherboards, etc now which will load test and monitor heat, etc. Need to make sure your ram and everything else can keep up though.
Used to be the case that some processors were just sold 'underclocked' and there were free gains to be had. However, as speed is so cheap these days, I don't see too much point in doing it. |

First of all check to see if your mobo manufacturer has a desktop app that allows you to change the settings. If not, go into the bios at boot time and look for CPU settings (could be under advanced settings, or processor/CPU settings or similar) there will be a clock speed and a multiplier option although some will have multiplier locked - there are ways round this though)
Simply set the clock and multiplier so you get the desired speed, then (F10)save and close and wait for the magic smoke... If you need to ask about anything above I suggest you may not know enough to not break anything. Do a search on Google for overclocking sites, there's a lot of info out there, and maybe a walkthrough for your specific board/CPU combo, including any warnings, etc |

As ever, go slowly and test for stability after every small change.

Once you've done your overclock, run something like Prime95 to makes sure that the system is stable. I'd also recommend downloading CPU-Z.

Forgot to mention......
It's normal when doing a more intensive overclock to have to raise the voltage of the cpu. Always make sure that you keep the cpu voltage wthin it's operating limits. So long as you do this, the worst that will happen is you will need to reset the CMOS and go back to stock settings. However, if you run your cpu at a higher voltage than is recommended, you run the risk of frying your motherboard/cpu.

i'd highly recommend an upgraded CPU cooler for any overclocking. Heat significantly shortens the life-span of components as i'm sure you know.
