ok, overclocking is making a component of your computer run faster than its stock speed. for the cpu, there are 2 ways to overclock: the easy way, and the slightly more hard way. the easy way is you just increase the multiplier of the cpu. for example, you get the 8320, with a stock speed of 3.5 ghz, meaning it has a multiplier of 17.5 (because most cpu's have a front side bus (fsb) of 200 mhz) cuz 200x17.5=3500 mhz. so, if you want to overclock to 4.0ghz, increase the multiplier to 20, cuz 200x20=4000 mhz. however, as you increase the multiplier, you need to increase the voltage aswell. if you are overclocking from 3500mhz to 4000mhz, you probly want to add about 0.075 volts, however you want to overclock in small steps, so i would suggest if you have it clocked at 3.5ghz that you increase multiplier to 18.5 so 18.5x200=3700mhz, and add 0.025 volts. if windows boots, increase it to a multiplier of 20, and increase the voltage by another 0.025. if windows boots, run a stress test like prime95 for a couple hours, and if there are no errors, then it is a stable overclock. if there are any errors, then add another 0.025 volts. if it still doesnt pass the stress test, then lower the multiplier to 19 and remove 0.025 volts, and try again. also, dont let it go over 70c ish, cuz then it will start to age faster. now, the slightly hard way: if a cpu doesnt have an unlocked multiplier, then you increase the fsb from 200 to, say, 215. therefore, 215x17.5=3762.5mhz. then you would add 0.025 volts (if it allows you too), and go into your ram speed, and either lower the frequency by 1 notch, or if the ram isnt at its max rated speed yet, leave it alone (you may need to add some voltage, like 0.025 ish). then, you need to try to get the ht reference clock as close as you can to 2000mhz, and if it has to be either higher or lower, set it to lower than 2000mhz. then run prime95 for a couple hours, and if it passes, and the temp stays under 70c, its good. and btw, you may need to increase the north bridge voltage by a tiny amount, do it by like 1 notch at first and run prime95. and you can do all of this in the bios menu. however, the fx chips come with a mediocre heatsink and fan, so if you decide to OC, i would get an after market cooler, like 212 evo for $30. and only overclock if you notice a significant increase in performance. and that is pretty much it

OC'ing might void your warranty though, so keep that in mind if you have a warranty.
