This MOBO seems to top the list in IOMMU grouping but I saw people say that later BIOS versions either broke the isolation of the first two PCIe slots or broke the passthrough of slot 1 completely.
References:
I probably can't use the older BIOS on the B650 version I'm looking at since I need updated BIOS for my Ryzen 9900X.
Unsure about the X870E version, so feel free to let me know, but that's for a potential, later build.
Anyone managing? Fixed? Needs a workaround? Needs ACS override? Is ACS override always a reliable fix?
Don't know if I'm over-worrying about just a couple people having problems or if that's a good enough number considering the niche situation of this specific MOBO series + Proxmox + dual GPUs....
And if anyone's going to mention alternatives, I want good USB separation too, so, maybe ASUS ROG STRIX B650E-E or the -F, or less ideal, the Gigabyte Aorus Elites, IIRC, from what I saw at IOMMU.info.
