Sierra won't boot

Hi!
I'm trying to boot Sierra and always get an error.

I've tried safe mode, nv-disable=1, multiple Multibeast options.. I've loaded the BIOS post as said on the tutorial.
In verbose mode i always get this:




I don't know if it is because of the unknown CPU (i7 4090k), the unmount of Recovery.. and don't know what to do about it.
The Mo is a GB-h87-D3H and 16Gb of kingston DDR 3.


Thank you for your...
