ASUS AMD Beta BIOS Releases

[Neera]

Hey bingo, or really any other person that can help me. I have a Athlon II x3 445 rana (m4a89gtd pro/usb3 mobo)and i wanted to try to unlock the l3 or 4th core (it's a deneb die). I tried the autounlocker but everytime i do it (switch or from bios) the red DRAM LED light comes on and i have to hit that MemOK button or w/e it is to reset the bios settings in order for it to post. I realize it may be a bad core but why would the DRAM LED light up and is there anyway i can try to manually unlock the l3 cache (or the 4th core for that matter, i don't trust this auto unlocker thing :X)? Would this bios update help this issue or what should i do? I contacted asus tech support and they responded (after 2 weeks), that you should contact asus overclocking department over the phone and well... I either get hung up on or dropped call so I don't know what to do :/. I have BIOS revision 1456. Perhaps maybe since my processor was released pretty close to this 1456 release date, it is not supported for autounlocking? will the 1602 BIOS update fix this?
