My reply:

Thank you for your quick reply!

Q1: The model of the processor you are using (please provide us with
the product code from the box as well?
A1: I have this problem with an E4300, product code: BX80557E4300SL9TB

Q2: How did you determine that C1E was not being fully disabled?
A2: CPU-Z always monitor the CPU-speed in realtime, and when my system
is in IDLE state, the multiplier instantly drops form 9x to 6x. I`m
using version 1.39 of CPU-Z. When i stress my system, the multiplier
goes back to the "normal" 9x, giving me the correct totalt frequency.

Q3: Have you disabled Enhanced Intel SpeedStep(R) Technology as well?
A3: Yes, it has been disabled in the BIOS (EIST)

The "Badaxe 2" is targeted at power/entusiast users, so an
error/problem of this kind is very damaging for the boards reputation.
This is also becoming a quite known issue in many tech-forums, as many
other also have the same problem. I really hope this "bug" can be
corrected in an upcoming BIOS, as I and many others like this board
alot.

Best regards
Jorn Ove Edvardsen
