    Hi. Im looking to open cores 3 and 4 on a kuma 7750 X2. this could be done by setting in BIOS option ACC to auto and EC firmware to hybride.
    now I flash my board to the new bios f5a with succes but the option EC firmware is missing. any idea?

    well if I cant with kuma I will try again with Phenom II x2 550.
    my problem now is to get an option " hybrid " in my bios wich i dont have (only option ACC)
    read this.."I read about how easy it was to unlock the cores and to overclock this CPU on a 790 mobo
    so I just wanted to see if I could do the same with my 550. MA790XT-UD4P that has the latest BIOS F.4.G went
    to the BIOS to set ACC to Auto and EC Firmware Selection to Hybrid. , when we use
    the new BIOS versions, setting ACC to Auto alone might not allow us to unlock the remaining
    cores. . After unlocking cores 3 and 4, I oc'ed it to 3600MHz,
    installed Vista Ultimate x64 then ran Prime95 for 12 hours with no problems. Next day, I ran CPU
    stress test with Everest Ultimate for 6 hours with no problems. Vista recognized the 4 cores
    as Phenom II X4 B50 and gave it a 5.9 PR."... well this guy did it apparently
