Okok i see, well, what you need to do is download the software, install it, try a little bit of overclock and test it.
If you see temperatures going higher than your "comfort ones" lower the O.C., after that, stress it with Prime95 for a couple of hours to see if the O.C. is stable and there you go.
By the way, your Motherboard is not made for overclocking, it's just a mainstream series, i'd recommend a really slight overclock to begin with
and then, take it from there until you find your exact point
