January 27, 20197 yr Hey, I'm currently looking for a nice mini-atx motherboard for the 1151 socket to work with my first ever unraid build. Does anyone know any good motherboard that will support Vt-d and split IOMMU groups nicely for VM's? I already came across these 2, but I'll prefere the gigabyte due to the 4 ram slot capability (future proof). - Gigabyte Z390 M Gaming [ Link ] - Asus ROG Strix Z390-I Gaming [ Link ] Does the gigabyte motherboard work nicely for unraid or do you guys have any better option? I love to here what's your opinion. Thanks! - Tjeu AKA Athyk Edited January 27, 20197 yr by Tjeu support requirements

Also, when you say socket 1151 do you care if the board is Skylake/Kaby Lake (series 200/C236 chipset) compatible or do you prefer a Coffee Lake (series 300/C246 chipset) board? Both are "socket 1151." The server boards (C236/C246) tend to support better IOMMU group separation than the consumer/workstation (series 200/300) boards. If you want i9 (9th generation) processor support, that requires a consumer/workstation board. Edited January 27, 20197 yr by Hoopster
January 27, 20197 yr Author @Hoopster Sorry, forgot to mention that. I'm planning to use the Intel core i9-9900k [ Link ] For the sizing, it doesn't matter. Both will fit in the case I like to use. Edited January 27, 20197 yr by Tjeu

If you want the i9 processor, then, yes, you need a Z390 (or in some cases, Z370, depending on the manufacturer) chipset board. How important IOMMU groupings are to you of course will depend on what you want to try to pass through to VMs. There are likely not a lot of Z390-based unRAID servers in use simply because of how new the chips/chipsets are. I am sure there are some and perhaps someone who has a Z390 board will chime in with their IOMMU groupings. Unfortunately, as I stated previously, the server boards tend to split out hardware into much better IOMMU groupings for pass through than the consumer boards do. Some of those limitations can sometimes be overcome with ACS overrides, but, not always. Generally, from a hardware perspective, unRAID runs on just about anything. Where you *may* find some issues, again due to the newness of Z390/I9, is in the Linux drivers. It *may* take until the 4.20 Linux kernel, and perhaps beyond, until some of the features are fully supported. Currently, the unRAID 6.7.0 RC series is using the 4.19 Linux kernel. Neither one of the boards you linked would be a bad choice. Lots of unRAID servers are running on their older siblings. It really comes down to what features you want/need on the board and which gives you more of what you need. i wish I could give you specifics, but, I have never used a Z390 board with unRAID or any other OS
January 27, 20197 yr Author @Hoopster Alright, thank you for the great explanation. The only thing I specificly intent to passtrough would be a graphics card as I want to run a windows 10 VM to game / render from so now and then. I don't think I'm gonna pass through multiple keyboards or mouses as I want to connect to it using RDP and already have my main gaming rig to use. Edited January 27, 20197 yr by Tjeu
