I'm having the exact same issues with the Asus Maximus VIII Ranger and the CMK16GX4M2B3200C16 kit. Very frustrating. I contacted Asus, they asked for some details, I replied, and never heard from them again.
As soon as I enable XMP and reboot, the system doesn't POST and I see error 55 on the on-board LED. The only timings that work are Auto @ 2133.
I feel like I wasted money on the more expensive Corsair RAM.
