    I'm curious to see if more than just ACC code updates were done in the new F2B bios for the UD4P. More specifically, the 1T/2T command timing is broke (hardset at 1T) and Bank Swizzle is always enabled as well in F2.

    I'm getting 4 cores without ACC on the GA-MA790FXT-UD5P with F3b bios. Still have sound problem. I thought turning off ACC would disable the 4th core and eliminate the scratchy sound but no. Too bad...4th core is strong.
    Back to testing.

    Same with the UD4P. Looks like I'm stuck with 4 cores now. Oh well, it's strong too, so I'm not complaining.

    If you pull power from the board and hit the CLR CMOS button, then power back up. you will have 3 cores again. Atleast that is my experience.

    Thanks, back to 3 cores and sound/color is fixed too. Still on F3b bios.

    bro20000 - Yea, I'm just killing time waiting for a 9x5 too. Never had so much fun waiting ha ha.

    Edit: I've been waiting since 939! But 5 of them keep me entertained.

    i want to get the X3 720 with the Gigabyte GA-MA790FXT-UD5P or UD4Pto use also DDR3 1600 Ram . Can any cpu 720 unlocked to 4 cores? Or only the 09/04 made? It's difficult i think to find in the market this date of build. Does anyone where to find it?
