OK. Since you've never OC'ed before, here's how I would start...
Enter BIOS and disable turbo mode. Increase the CPU clock multiplier one increment. Save, boot to Win, and stress test while watching temps. If good, repeat. Each increment should increase your clock speed.
Eventually, you will get an unstable result. When that happens, you can either back off and live with that, or start increasing the vcore. Instability is probably the result of not enough voltage. Go back into BIOS and find the vcore (sometimes called cpu voltage) section. Increase it in the smallest increment available and test again. You may have to increase it quite a bit to get stable again. Keep playing with the multi and the vcore to get your best OC. But AMD recommends 1.5V as the highest to safely take the vcore.
