AHCI/RAID small issue aside, this board is rock stable!
I was able to match my CHIVF clocks and then add some on top with the same stock CPU voltage and C'n'Q working

Turbo of up to 4.2GHz on 5 cores straight from BIOS is sweet as well!
So far my 24/7 setting with C'n'Q enabled is 218x16.5(x19TC), but more is left on tap as I've already ran this setup at 4212MHz TC for 5 hours with one app hang. On my old board I needed 1.5V for 4.2GHz TC on 3 cores.

Other than that BIOS needs some compatibility updates for AOD and ET6 needs rewrite
