Actually they have more than five 7GHz CPU at HKEPC, this I am 200 % sure because I saw with my eyes. (i'm Christian Ney, from carpo93's laptop at Campus Party)
i have a GA-Z77X-UD3H stuck at 16x after a crash, but not with so high frequencies like you, at 5,8ghz 3dmark 06 cpu test, tried f10, f9 and f8 bioses but no solution
