I had a similar situations to this when running my VMs passthrough with any method except one. Non-UEFI Unraid. VM running a Q35-2.10 machine, with OVMF BIOS. And a known valid rom for my video card. Especially crucial if your taking the GPU away from unraid (Headless) for your VM. Had to try a few different video bios (roms) to find one that would work.

Im running the Asus x399 Strix board with a pair of 1080ti, 32GB of 3200+mhz ram (cant quite remember the exact stuff *And CPU-Z is useless in a VM =l * a 40TB array of platters a couple terabytes of cache for the 2nd VMs vdisk, and Unraid use. And a dedicated NVMe 960 1TB evo pro for my primary workstation VM.

No iGPU. Dont believe there are any on TR, or Ryzen. Yeah Post is on the GPU in the first PCI-E slot. Then once Unraid is booted and resting at prompt (Non graphic mode) Then The VMs start up and take over the GPUs. After that Unraid is only accessible through SSH or HTTP.

I've seen several people mention needing a second card for unraid. Thats not been my experience. I have 2 cards, And 2 VMs utilizing 1 dedicated GPU a piece. Unraid runs headless just fine in my experience. And i can easily log into my unraid with my cellphone or another browser capable device when i gotta bring everything down for adjustments, config, etc.

Yeah. I would certainly go for no less then 32GB of ram on a TR Unraid system. So many Cores. Not enough ram for them all. The thing is unleashed on unraid. The possibilities are seemingly endless. But only if you have the ram for all of it. Honestly i have a 1950x with 32GB. And badly want more ram just for the cores i've got. Also dont use slow stuff. Its gotta be fast both TR, And Ryzen in general need good ram. And of course you want a 1080ti, The question is do you want a second one? multiple VMs with dedicated GPUs allows for some very interesting configurations. Especially if your a developer. Unraid and TR is power exponentiated =P. Thats a word right? But dont forget the ram..
