I became rather familiar with this guide when I did my unlock:
http://www.overclock.net/amd-cpus/535501-official-amd-k10-5-core-cache.html

It says,

Choosing the right motherboard:

In general, make sure the motherboard has a SB710 or SB750 southbridge and ACC is supported before purchasing. However, there are exceptions, as some motherboard manufacturers have disabled ACC core unlocking features. Rumors were floating around that AMD discouraged theO unlocking of cores. Hopefully the following list will clarify which motherboards work and which ones don't. Keep in mind that the BIOS revision plays an important role in unlocking. For example, with the Biostar TA790GX 128M motherboard, only 78DEA113 bios unlocks cores. The 78DEA525 bios DOES NOT UNLOCK ANYTHING.

There is also a mobo compatibility list you can check to see if your mobo is on.

P.S.
You didn't tell us what your mobo model is...

I can't be certain but my guess is that the mobo will be capable of unlocking-- However, and this is a big "however", you may need to use one of the older BIOS versions because ASRock (allegedly) nixed the core-unlocking capability of the ACC feature (due to AMD pressure).
