Ket, any chance to get in touch with your contacts re stupid issue for code 70/71??? I seem to have the same problem as zomee posted earlier, but probably even worse!
Can't even boot with stock/default settings as it keeps restarting. Managed to do some oce prior to that and after it got the code for the first time that is it!
Strangely.. this Turbo 50 setting overclocked the 2500K to 4.8GHz and worked no problem. When I tried to do it manually with exactly! the same setting it didnt work!

I am starting to hate this mobo so much...
