Update -
Crosshair IV Formula - Solved the VCore voltage jump with CnQ and LLC both enabled (not recommended for high OC) it appears. As soon as I have the fixed code I will release it, which should be this week.
M3N Series - We will have another beta shortly with a few core code changes but the board just is not going to clock as well as the 890FX boards, there is only so much you can do with a chipset designed before Thuban was a twinkle in somebody's eye.
