Motherboard compatibility and IOMMU

[4ntech]

Hello,

 

I'm planning new build with Core i5 8400 or 8600K and need some guidance picking out unraid compatible mATX or ATX motherboard with minimum of

8 or more SATA 3 ports my main concern is IOMMU grouping and video card pass through

This will be mainly used for file server, couple of dockers Plex, duplicati, and couple of VM's windows 10 . Can someone please provide some recommendation.

ASRock Z370 Extreme4 LGA 1151 (300 Series)

With IOMMU grouping there's really no way to check without trying it.

Can you recommend any mobo with your experience which works?

Well my motherboard in my signature, and an old motherboard based on an i5 3470s build, but that's it.  Best bet is to look at builds people here have done.

I have the ASRock x370 Taichi and have issues with IOMMU groupings.  First, the Bluetooth controller and Ethernet are stuck in the same group.  Second the non GPU pcie slot is also in this group, so passing through a pcie card is out of the question if you don't want to pass the onboard Ethernet through as well.

 

Very frustrating.  Iommu ACS override is able to split off all sorts of inconsequential hardware, but still leaves this big lump.

I have the same problem with my motherboard "ASUS ROG Strix Z390-e". Audio and network in the same group.

Do you have a motherboard to recommend?
