Have you tried to run 7-7-6-21 @ 2133mhz ?
I have had the same problem with SPi. I could run everything but SPi 2M+ but after days of sitting and trying I founded the right settings I've posted above. That made it stable for 32M.
Keep playing with subtimings and don't use much of them on Auto except those which I posted.

Playing with Hypers is hard but it worth if you want to do some crazy run
