Not every cpu can be unlocked dude, its not a freebie on every cpu, and it sometimes wont work at all.

You also need a compatable motherboard.

What are your full system specs and what is your back ground knowlege with PC's and overclocking like?

the board does support core unlocking within the bios according to the msi website.

enter bios menu> CELL MENU> and change the UNLOCK CPU CORE into auto and enable ACC (advanced clock calibration)

i've been through

phenom x3 720

phenom x2 550

and both of them have not unlocked and they were some of the earlier ones released.
