Asus M4A785TD-V EVO 2105

Hi!

I have Asus M4A785TD-V EVO with the newest 2105 bios. I'd like to unlock a multiplier for my processor and i read that it can be done through allocating L3 cache to the first core. I have a Phenom II X3 with already unlocked and stable fourth core. Can someone unlock the option to change multiplier or l3 allocation?

Thanks in advance
