While this may be of little comfort, do know that it's not just you. My 8120 does the same thing. Specifically what is happening seems to be that the TDP estimation part of turbo isn't properly disabled. You'll note that the further you overclock the more cores are throttled and for longer. You'll actually start going negative in performance gains somewhere between 4.3 and 4.6 GHz due to it. Any setting beyond 14x is going to cause it, however, so no matter what your BD isn't going to perform as well as it would on other boards. Your chip is going to head back to a 14x multiplier (on an 8120) to be precise. Consequently, if you want to mitigate the problem in the mean time between now and when Gigabyte fixes it in a future BIOS, you can overclock using a high HTT and lower multiplier to reduce the impact. It sort of negates the purpose of a black edition, but it'll work.
