This is overclock.net. OF COURSE! but yeah, you probably can in all seriousness, it can't hurt anything to try.
First, you're gonna want to do some reading on basic overclocking, You'll be using programs like prime95 to stress test your chip. Basically, overclocking runs, bump voltage, up speed, test, if it works, push chip higher without changing voltages until it fails, then push voltages a bit more, rinse and repeat until you've reached a maximum temperature that you feel safe with for your cpu, and or a maximum voltage for your cpu. You'll also want to use HWMonitor to monitor the temps of everything in your case, from your northbridge to your cpu. This, is obviously a very quick run-down of what you'll be doing, voltages are different for different cpu's, and it is extremely important that you do a good bit of reading on other people who have overclocked a similar cpu to what you have. You should definitely research maximum voltages, then write those down so that you know what you're not ever going to go over voltage wise, so that you don't fry the chip.
Another thing to remember, is you are going to want to overclock just your cpu in the beginning, by upping your cpu, your memory is also going to be overclocked, so you're going to want to take the memory multiplier and down-clock it all the way until your cpu is stable, then start bringing your memory speed up. A lot of times actually, memory speed, can be what holds back an overclock.
