Hi

I managed to unlock my 550 with a M4A78-E using bios 1104. In my previous post I wasnt able to do this but its very unstable I get graphical glitches.

I did manage to run prime95 and all cores seem to work ok. Im sure its just a bios update for this motherboard, Im emailing ASUS as we speak to see if they can rectify this problem.

Mind you, Its took 3 emails to ASUS as they dont know how to enable or find the unleash mode!!
