I have A Phenom II 550 BE 0951APMW and i failed to unlock it with an Asrock 780LM-S (AMD 760G nb and 710 sb) bios rev 1.10
I can pass POST and enter windows but the computer hangs at logon screen.
tried to lower the MHZ for the other 2 cores, tried to increase vcore voltage up to 1.5v, but all i get is the logon screen in windows XP then a crash.
some of my friends succesfully unlocked 550 BE with the same mainboard with no probs.
I wanna try to unlock it to 3 core, but i dont know how.
Can you help me ? I dont think i can disable cores from my bios.
All i have in bios is ACC auto / per core / all cores / disabled and CPU active core control
I was able to unlock the cores in a 550BE and a 545(non be) using the biostar TA790GXE 128M but I needed to flash to bios#78DFAA26.
It can be found on the biostar usa website http://www.biostar-usa.com/app/en-us...s.php?S_ID=408
BTW both ran prime stable for 12 hrs
