Please Please Help me unlock the BE550

I would use punctuation, it almost always help people understand what you need, and I also wouldn't consider this something that needs an urgent reply.

I don't think that you've really read up on unlocking the disabled cores of the Phenom II's, have you? Not only does it have a 50/50 chance of even working at all, but even if it does "work", the unlocked cores may be unstable and cause crashing.

Also, you don't have the proper motherboard to allow any kind of unlocking. The process requires that you have an AMD-based motherboard with either the SB710 or SB750 southbridge chip. Your motherboard is based on the Nvidia 8200 series chips, so you won't be able to do any unlocking.
