Thanks! I’m still in the planning and parts-buying phase — I’m currently running Unraid with Docker containers and a NAS setup, and I’m looking to level up my build. The new system will prioritize Docker and storage performance, with Quick Sync via the iGPU for Jellyfin transcoding. Down the line, I plan to add a gaming VM with GPU and USB passthrough, so I’ve been researching IOMMU grouping and PCIe layout to make sure I’m covered. For storage, I’ll start with two or more 14TB HDDs plus a parity drive. I don’t need an HBA yet, but I wanted to make sure the board could support one later if needed — your screenshot helped a lot there, especially seeing that the USB controller has its own IOMMU group. If you’ve run into any quirks with passthrough or Quick Sync in Unraid on this board, I’d love to hear about it. And once I build things out, I’ll share an updated IOMMU map to help others too.

Hi everyone, I'm planning a new Unraid build and am considering the ASRock Z790 PRO RS WiFi motherboard paired with an Intel i5-13500. My main use case involves VM passthrough, including a dedicated GPU, a PCIe USB controller, and potentially an HBA card for storage expansion (far into the future). Here’s the build I'm envisioning: Intel i5-13500 ASRock Z790 PRO RS WiFi 1x dedicated GPU (for a gaming VM) 1x PCIe USB controller (for passthrough) 1x HBA card (optional/future expansion) 4 NVMe drives 3–4 SATA HDDs (1 parity, 2–3 data drives) - to start What I’m hoping to confirm: Does this motherboard allow clean IOMMU grouping (i.e., GPU, USB controller, and HBA each in their own IOMMU group without ACS override)? Are VT-d, Above 4G Decoding, and ACS override options available and functional in the BIOS? Has anyone used this board with Unraid or Proxmox and successfully done passthrough for multiple devices? Does anyone have an IOMMU group dump they could share (e.g., from /sys/kernel/iommu_groups/)? I’d prefer to avoid relying on ACS override if possible, so clean grouping out of the box is ideal. Any insight or experience with this board would be greatly appreciated before I finalize the purchase! Thanks in advance!
