Latest Bios x570 and Iommu groups...Is it prime time yet or should I wait

Getting ready to upgrade my system to team red. I’ve been following many threads on the latest bios upgrades for x570 boards and the quality of iommu groups. It seems there are still significant issues. Does any motherboard manufacturer have it right yet?

same here. So far I’m still waiting.
May be the launch of the 3950X will help clarifying things, as more cores implies more often the use of virtualization so more feedback.

Sounds like gigabyte might have it right with the latest bios update. Looking at the aorus master.

The aorus master on 1.0.0.4b has pretty good groups. Here they are. I also have ACS and AER Cap on in the BIOS. No ACS patch on the kernel though.
