Muhamad Aidil Karim Posted June 24, 2021 Share Posted June 24, 2021 (edited) Hi, I am planning to deploy 2 VM on my unraid. Each VM will have dedicated GPU assigned. Is there any requirement for this setup? Can I used same GPU model on my unraid? My current setup are as below: Motherboard: GIGABYTE Z490 VISION G Processor: CORE I9 10900K RAM: VENGEANCE LPX CMK (3600) 16GB x 2 Edited June 24, 2021 by Muhamad Aidil Karim Add Information Quote Link to comment
Putschgi Posted June 24, 2021 Share Posted June 24, 2021 Hi Yes you can. I have a PC with 2 GPU's (RTX 2080 Super and an old GTX1080 Super) that works fine. my latest project is a PC with 5 GPUs (4x RTX 2060 and a GT710) that also works very well, except that my new Threadripper does not release the GPU in the 1st slot for GPU Passtrogh. But i'm working on it.... Quote Link to comment
Muhamad Aidil Karim Posted June 27, 2021 Author Share Posted June 27, 2021 Thank you for sharing your experience. I'll looking forward to include multi GPU in my build. Quote Link to comment
Sinister Posted July 6, 2021 Share Posted July 6, 2021 Is GPU passthrough working now on 6.9.2 ? didnt seem to be the case a month ago at least, alot of people had to revert to 6.8.3. I would like to know your experience. Quote Link to comment

I have the same setup as you with gtx970 on the 16x slot and I cannot get mine to work. It used to work but unraid updated and it stopped working. It has almost been a year and I would like to get this resolved. I also have an sas card in the bottom slot. Would you mind sharing your configuration or bios settings? I believe unraid is set to non uefi (legacy) mode if that matters. Quote Link to comment
juan11perez Posted July 6, 2021 Share Posted July 6, 2021 I'm on this bios: American Megatrends Inc. Version 5843. Dated: 03/11/2021 and have the following: 1st slot Radeon RX 570 which I use for MacOs and Windows VMs 2nd slot GeForce GTX 1650 for Archlinux Vm - daily driver 3rd slot GeForce GTX 1050 Ti - hardware acceleration. i.e plex, zoneminder, mlapi, etc. I'm on Legacy boot. non uefi. In bios I've only modified the following: HVM: Enabled IOMMU: Enabled Memory Freq: 3000 Power state: Power on restart Fans: all at max I think that if you're passing the only GPU you have, you need to add the GPU bios in the vm.

Thank you very much. I am using the edited rom file. Did you edit the vifo on the unraid bootup process or just change settings on the VM screen? Quote Link to comment
juan11perez Posted July 7, 2021 Share Posted July 7, 2021 (edited) I only added the vbios on the VM set up tab. And you'll also need to bind that card in tools >> device setting. Edited July 7, 2021 by juan11perez Quote Link to comment
kilobit Posted July 8, 2021 Share Posted July 8, 2021 Well, I got it to work once; it booted to uefi bios and then the vm worked. I then needed to reboot my vm and it never came back up so using my phone I logged into the unraid machine and the vm would restart but nothing on the monitor anymore. Rebooted unraid and nothing. So If I passthrough like your saying to by assigning the immo graphics card/hdmi sound then unraid will not grab the card on boot. I assume you have your vm to auto boot? I will try this and report back. Quote Link to comment
magicman32 Posted August 16, 2021 Share Posted August 16, 2021 What I am trying to do is have 2 gpus for passthru to 2 seperate vms Problem: Installed 2nd gpu in unraid server (identical amd rx570 8gb cards) when I start a single vm....my vms tab disappears and go to settings vm manger and thats gone too Setup: I have a linux vm and a windows 11 vm installed when it comes to vm setup each vm has its own gpu with seperate id (so I know which card is which), each card has its own iommu group Outcome: My server becomes so unstable to the point I have to reboot, because it freezes so I cant get any logs to see whats wrong........ at first I thought it was a power issue, I started with a 750w psu running 2950x threadripper 6 hdds and 2 amd rx570 8g gpus So I upgraded the psu to a 1000w psu and getting same issues, So I have taken out 2nd gpu and system is now stable once more...... Im not sure if its a setup thing or that I have identical gpus If someone has some insight to dual gpu setup that would be great, Im not sure what to check for in logs.........any help would be greatful, a bit lost and disappointed I cant get this working I have same results with 6.9.2 and now with 6.10 rc1 Quote Link to comment

I have an old fractal design xl r2 and it was near perfect. The new 7 xl is quite expensive (at least for me), but it seems it has all one should have need; it has also a 3 vertical slot space to install a pcie riser. Quote Link to comment
