Okay. What about the overclocking side of things? If you can ease my mind with that then I'll give it a shot. Lol.
Just by going into the Bios and upping the multiplier to 42, will give you an OC of 4.2Ghz without having to change voltages. But if you wish to go higher, then it can get a little more complicated. But should you wish to go higher, then like everyone else, you need to do a little research on Overclocking. You can also open a thread in the Overclocking forum, where the guys in there will only be to happy help with tips and advice. Just remember, we were all in the same position as you at one time.
