On this thread a user was having issues passing through a gtx 690, so you will probably have issues as well.

Virtual Machines Dual Chip GPUS

I registered just to give you a reply: I have tested GTX690 with UnRaid. You are able to get each GPU in a separate IOMMU group with ACS patch. You can boot inside the VM with only one GPU, but I am unable to get the drivers working. In windows VM I get code 43 and thus the nVidia driver cannot be installed. Also the GTX690 behaves weird in native windows 10 on my machine Ryzen 1700, Asus X370F. I get the same code 43 almost every time. I have tested this with 2 GTX690 so I assume the todays motherboards just do not understand the PLX chip on the card. Buildzoid mentioned in his video, that the MARS 760 does not work correctly in todays mobos and it uses basically the same components as GTX690. If anyone feels like helping with the issue, I would appreciate it. If anyone has a UEFI compatible bios(PLX included) for the GTX690, that would be most helpful. Flashing the EVGA files from gdrive(linked from nVidia forums) does not seem to work for me.

Thanks for the reply, but it seems he has a motherboard problem in addition, my cards seems to work perfectly fine under windows 10, even drivers and everything works perfectly, even the 3dmark results seems to back that up.

Im testing with windows VM as we speak, and its seems “fine” for now, and, the PLX chip shouldnt matter like he is explaining, that seems more a fault with his card or motherboard, the PLX chip shouldnt have any impact on that, since many cards that are beeing passed thru indeed use a PLX chip

But i appreciate the reply

EDIT: and error 43 is just a matter of tricking Nvidia drivers, thats a common issue when passing thru nvidia cards

Glad to hear it is working for you, all I remember hearing about are dual gpu cards not working for passthrough, or only working when both cores go to the same vm.

Also for code 43, it does not show up only from the driver gimping that you talked about, but it also shows up in a couple other places. It will show up if you try to passthrough the boot gpu if it is a 1000 series nvidia or later. It also show up if you try to passthrough most laptop gpus.

Are you able to pass through one GPU from the 690 (e.g. half of one graphics board) to one VM and the other 690 from the same board to another VM?

i didnt get that far before the mobo decided to crap its pants, going back to use my dual xeon for the project
