October 24, 20178 yr Hi, First time poster here ! I'm currently in the process of ordering parts for my new build and I would love to get a Threadripper 1950X CPU, however I want to make sure it's fully working with Unraid. I would also order 2 GPUs, either dual GTX 1080 or dual AMD VEGA 56 or 64. I would use Unraid for the following: 3 VMs: 1 VM with Ubuntu server (no GPU passthrough) (2 cores - 4 threads) 1 VM with Windows 10 for DEV & Gaming (for me) (1 x GPU passthrough) (6 cores - 12 threads) 1 VM with Windows 10 for Gaming (for my son) (1 x GPU passthrough) (6 cores - 12 threads) The remaining cores (2 cores - 4 threads) would be allocated to Unraid. Each VM would have it's own SSD or NVMe. I don't plan to use any other functionality of Unraid i.e NAS. My question: I want to avoid any trouble with my configuration and would like to get the best performance for each of my VMs. So I would like to know what is the current status with VMs and GPU passthrough with Threadripper ? Will I run into setup issues, studdering, performance loss, etc ? I'm looking at Threadripper as a platform, but would be willing to go the Intel route if there's too many issues associated with Threadripper. However, going on Intel would probably add 1000$ to my build. Can you share your feedback/comments on this ? Much appreciated !
October 24, 20178 yr Bump. I'm looking at going with the 1950X, and already have a Titan X (Pascal) I use for gaming with a Windows VM. I definitely want to make sure the GPU passthrough is working correctly before I pull the trigger on a the new mobo, CPU, RAM, and water cooling equipment. I know I've seen mention of problems with GPU passthrough on here before, so I'm off to find those old posts and see if they were ever resolved. :-) Edit: I should mention that there seem to be major fixes for Ryzen/Threadripper in the 6.4 release candidate builds, I think primarily due to having a newer Linux kernel. I'm not really wanting to run an RC, and will probably wait for the official 6.4 release, which I'm sure is Coming Soon™. Edited October 24, 20178 yr by gilahacker

October 28, 20178 yr There is hope: https://www.phoronix.com/forums/forum/phoronix/latest-phoronix-articles/985575-amd-ryzen-npt-fix-discovered-for-better-pass-through-graphics-performance
November 6, 20178 yr I just built a 1950X system with the unRAID RC that has the NPT fix. But my GTX 960s won't power up during VM start. There's another thread with details. Edited November 6, 20178 yr by coppit
