You've got an AMD Black Edition so overclocking couldn't be any easier
.
You go into your BIOS, find where is says AI Tuner or Overclocking or whatever (normally second page in BIOS) where all your CPU settings are.
Sometimes you need to set something to "manual" before seeing options for overclocking.
You simply then increase your CPU Multiplier to get a better clock.
You're currently at 3.2GHz, which means you've got a 200 FSB and 16x multiplier. 200 x 16 = 3200 / 3.2GHz. If you increase your multiplier to 18x you'll have 200 x 18 = 3600 / 3.6GHz.
Because you're now running at a faster speed, you'll often need to increase your core voltage to keep it stable.
Best way to do this is to increase your CPU Multiplier by a single point (sometimes half a point) and then boot into windows. Once in windows, run a stress test such as Prime95 (with the option "round off checking" turned on). If you can run Prime95 for say an hour or two without any errors - you're stable.
If you do get an error you have two choices, lower your CPU clock speed, or add voltage to it. You should add voltage the same as you did your multiplier - go into bios and increase by a single increment. Once you've added a little volts to your OC, boot into windows again and now see if you can run Prime95 without errors.
Once you're stable at your new speed, you can push your multiplier again, then your volts and keep doing this untill it doesn't matter how many volts you put to your chip, you just can't get stable - now you've found your maximum speed.
Once you can't get stable, you need to lower your clock speed just a little until stable again - that's the fastest you're going.
Done.
Sorry if this is a bit rushed, I'm kinda' tired lol.
If you need more help post again and I'll do what I can to help.
