When you enter it you should see some settings. Put ACC to the auto setting for starters, and most importantly on Gigabyte boards there is a section labeled ec firmware. When you enter that you have a choice of amd normal or hybrid. Chose hybrid hit enter and it will prompt you that it has to reboot and change itself. Hit enter again, it will change and reboot. If your cpu unlocks you will boot into windows at which point you can use CPU-Z to verify it and maybe start testing for stability. If you cant boot into windows with some stability or if it crashes immediately after, reboot and go back into bios an undo what you changed hit enter and reboot into windows as normal. There are no guarantees, some of these chips were locked for a reason. You should be able to use that board.
Awesome thanks for that, can anyone confirm this works?

I have been told it doesn't. But I think it does :s
