Sometimes XMP works sometimes it doesn't. If you set it to optimized defaults and uyse XMP it should work.
On to the meat and potatoes. If you plan on optimizing at all as in any OC I would leave XMP off and enter your setting manually. You get far better control and much better results as very small changes can mean the difference of a getting the OC you want or not. Also remember frequency is not everything. You can actually have faster ram with a lower latency and lower clock.
Latency/freq x 1000 gives response time, less is more.

Another thing to try: Add a little, about 50mv, to DRAM voltage. It's possible the M8F was doing that for you, but the M9F does not since there is some variation in actual voltage from board to board even when the setting is the same.
For example, if the XMP profile sets DRAM voltage to 1.30, raise that to 1.35. After you get it POSTing and booting, try reducing that voltage in .01 steps to find an efficient operating point.
