bios to unlock X2 550 BE on 790GX-G65

[karlo_z460ml]

I 'hv X2 550BE (batch#0922apmw) which batch is mostly succesfully unlock by another brand mobo. My friend was did it with DFI and Asrock mobo. I already tried with 790GX-G65 with bios version 1.3(05/08/09) but failed. Do you have another bios beside ver 1.3 which can successfully unlock X2 550? I would appreciated if you give me link for download.
Thank's

If you can't unlock now 1.45 might not make a difference? There are articles through searching that can lead you too the Beta bios's. My X3 will not unlock with 1.44, poss yours will. For me I am just as happy with just 3 as designed because the performance is great, running at 3.519, and I realize mine just is one that wont. I have read a few successful x550 unlocks to 4 core. I am learning about this myself and have even read that a full power diconnnect and restart is part of success along with the correct voltage adjustments. hope it helps you.

Even if some of them can be unlocked doesn't mean they all can. You have to realize that he X3 and X2 versions have disabled cores because those particular cores are defective in one way or another.
