--- Comment #9 from Thomas Langkamp (thomas.langkamp@medicalschool-hamburg.de) --- Yes. With the new BIOS this is reproducible only with XMP enabled.
In the other bugreport I read about
amdgpu.ppfeaturemask=0xffffbffd
I just tried it. Until now this seems to fix it, even with XMP profile enabled! I will report back if I get a black screen again. As far as I know with 2 monitors attached the VRAM is always clocked high, so it makes sense that disabling the VRAM power management through this featuremask works around the issue. But surely a proper fix would be appreciated.

--- Comment #8 from Alex Deucher (alexdeucher@gmail.com) --- Do you only get the MCE errors when you set the XMP profile?
