Yeah dont buy the 720 and expect to automatically get a quad out of it, its really not guaranteed and many people cant do it. I was able to unlock mine though
basically, i tried ACC auto, 4th core not showing up...
tried all cores, still not there...
tried -12 and 12%, won't boot, had to clear CMOS (pain in the ass as you had to take GPU out to take off plastic cap off CMOS)
dang it... might as well buy a real quad... Any potential good future quads on AM3?
main use is for gaming...
For Gigabyte did you see an option in the bios called:
"EC Firmware for Advanced Clock Calibration"
It can be set to the following: (Wording as shown in the bios... bad grammar and all.)
Normal = Used AMD normal EC Firmware for Advanced Clock Calibration
Hybrid = Used AMD particular EC Firmware for Advanced Clock Calibration
From what I understand you set it to Hybrid to unlock cores/caches AND ALSO turn on the ACC. (May or may not need ACC. But think of "Hybrid" == "Unlocking mode".)

This is what I did for my 720 and it unlocked it. Try and set it to 'hybrid' and 'auto' for ACC.
Course, I bought mine back in March. I read somewhere that the newer 720's don't unlock very well.
I unlocked mine over the weekend with a Gigabyte board, just as Dlux said. Hybrid + ACC (either AUTO or ALL CORES, both work), and I just bought my CPU on Oct 2nd from New Egg.

mine was one of the first 720s, way back in March... along with the UD5P mobo... and maybe i'll try again, now that you mention this "Hybrid" thing... Or is it a BIOS thing? do i need to flash it to a new BIOS to get that option, is that why?
where do you exactly find the "Hybrid" option? I know Ctrl+F1 gets you ACC, but where the hell is the hybrid?
ahhhhh ***... my bios was outdated... i have to get the F3K bios... but frankly, i never flashed any BIOS before... ah crap.
Its simple. Go to the mobo makers website, find the newest one and download it. Unzip it to a thumb drive, plug it in, load the BIOS and then look for a BIOS update setting.
Most newer mobos come with that option which I love since floppy = crap. But if not, they should have a Windows based flashing tool that you can use at your own risk. I don't trust Windows based flashers. Never know what can go wrong....
Also, remember that even if you get the latest BIOS and flash succesfully don't bank on it being able to unlock. And if it does, its not guranteed stable since you might have gotten one with a actual bad core which you wont want running as it could corrup system files and destroy your OS install.

Gigabyte has a utility called @bios which makes it possible to update your bios through a program that you can download from their website. Its very easy, i've done it before and has no problems. Either look how to do it in your motherboard manual or look on the gigabyte website.
Yep, same as Asrock, a utility that you download directly from the website and you launch from Windows... very easy =) .... as far as being risky, I have never had a bad flash and hopefully will never have one.... Dual bios is a + also.....
