which can i overclock?

[Hauhnar]

My rig is
Intel core i3-3220
P8H77-M LE
G.SKILLS RIPGAWS X 4 GB 1600Mhz
COLLER MASTER THUNDER 450W
ASUS NVIDIA GT 640 2GB DDR3
Which components can i overclock?
Is my PSU enough?

If your asking this question you probably shouldn't be doing it. However, you can overclock all of the components (to overclock the CPU you're going to have to anyway). This isn't the best setup to do overclocking on and your gains will be minimal, might be a good first start at it though if you decide to upgrade later.

You've misspelled some of the components Manufacturers incorrectly, and I note this because you want to read everything precisely and enter correct voltages.
But it's a locked chip, so you can only overclock by raising the BCLK. But on stock cooling you won't get far, and by raising the BCLK-you're raising everything. The RAM, CPU, NB...etc Frequencies. So you'd have to have a good understanding of the voltages and components that'll be overclocked. So start searching and reading-there are plenty of guides here and on other sites lying around on Intel overclocking.

I'm new at this kind of things.. i dont know a thing about OC. Thank you so much for all the feedback..
