Thanks, I'll check it out. I can't toss in a cheap video card as there are no more PCIe lanes left that are large enough. This is more of an "trying to find a solution that does excactly what I want, no matter how difficult it may be"

Hi. I'm currently running unRAID 6.3.1, and I've been trying for quite some time to passthrough two GPU's to one VM each. I'm currently using an Intel i7 3820, a NVIDIA GTX 960 and 980 cards. They system does not have an IGPU, so the system has no other option other than booting to the 980 card. I am able to use both cards if I give the VM the 960 as the primary and 980 as the secondary video card. Both cards output video and there's no issue with this setup. The issue comes when assigning only the 980 to a single VM. My Dell monitor says there's just no output from the video card. I even installed TeamViewer on the VM (in hopes of getting SOME video), but I'm just getting a black screen. I can use the 960 card perfectly fine on a VM. If I swap the cards (using 960 as primary and 980 as secondary), the 960 becomes unusable and the 980 works fine (unless I assign both video cards to a single VM again). Please don't reply with "this isn't possible", or any hardware-related solution. Yes, I perfectly know that the best solution would be to buy hardware that supports internal GPU (or just roll with AMD), but I'd love to at least TRY to get it working. I believe that disabling VGA console output on boot would hopefully work, although I have absolutely no idea how to go on about this on unRAID. All ideas appreciated. I feel like I'm really close (judging by the fact that I can use the primary video card if I use it together with the secondary). and I hope that someone with a deeper understanding of the unRAID OS can help me find a software-related solution to this. What I've tried: - Booting with both VNC and 980 passthrough gives display output to VNC, but no output from the 980. Checking then 980 in devmgmt.msc gives this error: "Windows has stopped this device because it has reported problems Code 43". Attempting to reinstall the NVIDIA driver doesn't work; the installer fails on "installing graphics driver" with no error log to be seen. - Reinstalling the driver in various different VM configurations - All cores assigned to VM - HyperV disabled - Using i440fx-2.7 (should I try with Q35?) All ideas or comments appreciated. If I get this to work, I'll grab another system and try the same solution using different video cards and make a tutorial on it.
