I did a forum search and I found threads posting results of the unlock, but as a noob I don't know HOW to unlock it. Just a paragraph explaining "your batch must be the 4th week of 2009, you must have a mobo that has ACC for Auto, blah blah blah." But no actual step-by-step instructions. I have both the 0904 720BE, and a 790X w/ SB750 motherboard that has a BIOS updated specifically for ACC. Now what?

How is it done? Thanks in advance.

All Black Editions come unlocked.
750sb has ACC compatability built in.
Go into the bios and have fun, OR if your bios dosnt do the OC thing. Go download AMD Overdrive

If your talking about unlocking the 4th core check this list and see if your board is on it you may need to update your bio's to get it to work but it is hit or miss weather the 4th core will work or not. link

Ive got a 720 and a Asus AM3 mobo and I had no luck, but instablility when using the ACC function. Do yourself a favor, and OC to 3.6. I did and Im as happy as can be.

Unlocking the 4th core can cause a host of problems from temp readings being gone, and instability. Im glad mine didnt unlock. I love my OC.
