fartmaster Posted August 19, 2023 Share Posted August 19, 2023 Let me just start with I am sorry to join the other 1000 posts about GPU passthrough, but it seems as though any fix I try will not cooperate. So, I have a server that runs as a media server (plex, sonarr, radarr etc.) which uses a GTX1660 Super for transcoding, all works as intended. My house mate handed me his old GTX650ti so I thought I would have a crack at GPU passthrough for remote gaming (retro games, nothing too serious). So I have been searching and following guides for about a month now trying to get it to work, I am currently at the point where my VM will see the GPU, but refuse to use it (the infamous error 43). I have been following the guide below to try and get my remote gaming machine working: https://forums.serverbuilds.net/t/guide-remote-gaming-on-unraid/4248/9 I have watched and configured my GPU passthrough as shown in all of spaceinvader ones videos. What I can remember I have tried so far: - IOMMU is enabled in BIOS - ensured no issues with old gpu (tested on another pc) - vbios dump edited with hex editor and configured for VM - enabled and disabled hyper-v - edited the xml, here's the entire file as it stands (I have chopped and changed the xml A LOT, so any fixes are very much appreciated): <?xml version='1.0' encoding='UTF-8'?>
