Not so much the CPU but the board we need to know about. If you don't know it then give a model and the power that be Google will tell me.
4 things you need to take into careful consideration before OCing is done.
1: Can my CPU be overclocked? Do I have an unlocked multiplier?
Some Intel CPUs cannot be overclocked the tried and true FSB (BCLK) way due to limitations with everything being tied together, in short and sweet. An unlocked multiplier is needed for these CPUs which are marked with a K on the end. AMD equivalent would be Black Edition, or K as well for the APUs.
2: Does my motherboard allow adjustment of FSB(BCLK) and voltage control?
You need to be able to raise your multiplier or FSB to increase your core clock speed. Without this, you don't OC. Some AMD systems can use Overdrive to raise these settings but a bios set OC is always best. In order to maintain stability at higher clocks it requires more voltage. Without extra voltage at higher clocks your CPU will crash.
3: With more voltage requires cooling. It isn't wise to OC on a stock heatsink, no matter what it is. You will need to fork over for some aftermarket cooling which can cost as cheap as 20 bucks up to 1000+. Sky is the limit really. A good CPU cooler is useless with a cheap *** case though. If you can't get air to whatever it is you are trying to cool then might as well give up.
4: RAM speed and dividers. Most modern boards allow you to set your RAM divider lower or higher to compensate for higher FSB(BCLK) clocks. If you can't do this, then your RAM must be fast enough to match a 1:1 ratio with your FSB because when you raise FSB you raise RAM speed too. A CPU with an unlocked multiplier doesn't do this, which makes those so easy.
