First Time Over Clocking

[Dracoth]

Hi there I am new to the forums as this is my first time I have looked at over clocking my computer.

My System is as Follows:
GA-M720-US3 (rev. 1.0)
AMD Phenom II X2 555 Black Edition 3.2GHz Socket AM3 6MB Cache
Akasa Venom Socket 775, 1156 A1366, AMD 939, AM2, AM2+ & AM3 Heatpipe CPU Cooler (With 2 Fans
4g DDR2 DRAM 800Mhz kingston

I am hoping to unlock it to quad core.
If any one has any hints or tips and what is the max i could over clock it to with this setup it would help a lot.

Thanks for looking.

Unlock to quad core

Would I be able to unlock to quad core in bios or do I need another program?

Bios

I have just checked the bios version and its F6 is this the right bios version? (read on tomshardware for some more research) I found that the bios version means it might not allow me unlock the 4 cores is this right?
Finally if the bios version is the wrong version is there a way I can back date it?
