Hmm now having problems with 0905 here on the CH IV.

C1E and cool and quiet are greyed out. I can't enable them.

More importantly I can't get my voltages to stick beyond a certain clock. I was doing 4.0GHz fine on my older BIOS, now I can't get past 3.5 because it resets my voltages when I change my CPU clock beyond a certain point.

My OC fails because it's trying to apply stock voltage when I swing @ 4.0GHz.

I'm using all the settings I did before for 4.0GHz, ie LLC and offset are disabled.

BIOS is acting weird. I tried flashing it again, and it didn't change the situation.
