actually its really simple, but i'm not sure if every motherboard has the feature. but you should be able to increase the multiplier since it can change a little bit. basically, you go to the overclock section of the bios (or the CPU settings menu if ur MOBO doesn't have that feature) and increase the multiplier. on my motherboard, that just meant enabling the "NO K OC" Feature which handles the increase on its own, since you don't have AsRock, it will be different. Just increase the multiplier to 37, which is the highest it goes for that CPU. That's pretty much it, it's not that hardcore so no need for special cooling. another important part, and this may turn off on it own if you have the right bios, is to disable the turbo step and speed step technologies. those are the new intel features that automatically increase GHz depending upon performance. if you leave those on, they override any settings you have and will keep the CPU in normal mode.
in my BIOS I can set the multiplier per core, I didn't mess with that since I also did not then want to go into windows and set affinities for each application just to keep in line with the overclock. I found another program that lets you see the Per Core GHz, and it was the same since I did not set the cores individually
the best bet is probably to just go to the manufacturer's website and see if it gives instructions about OC'ing. Do you have the same CPU as mine?
