System freeze after login with Chimera 2.0.1 install
Try updating bios version to the latest beta one, too, on top of bios settings. I'm running 12a or something like that right now, because the motherboard did not see my ARECA raid controller in any other port than the 16x PCIE.
I did not change anything other than over-clocking the CPU to 4.3 via per core turbo boost multiplier, rather than overall multiplier. The rest of the settings are factory defaults. Maybe I changed something about thunderbolt ... but can't remember exactly what, I was trying to get it to work but gave up on it, no way to attach external storage, only displays and black magic UltraStudio type devices for video capture.
