Hi Guys,

I am somewhat new to Unraid and I had my NVIDIA GeForce GTX 970 (I know it's an old card) working totally fine before the upgrade to Unraid VER. 6.11.5, I am still able to passthrough the card but there is no output from the GPU to my monitor and when I remote into it via remote access I get a Code 43 error and it goes away when I reinstall the driver. However, on restart or on shutdown the code 43 comes back. I have tried all kinds of fixes that have been offered on this forum. Any help would be very much appreciated.

Attached is the xml file for my gaming vm.

 

Motherboard:
ASUSTeK COMPUTER INC. ROG STRIX Z590-E GAMING WIFI

 

CPU:

Intel® Core™ i9-10900 CPU

 

GPU:
NVIDIA GeForce GTX 970

 

I do have the GPU grouped together in the IOMMU group.

Added more info

Could be related to layout in the guest, you added multifunction for gpu but you forgot to update the target bus for the audio aprt, replace with this and test:
 

    <hostdev mode='subsystem' type='pci' managed='yes'>
      <driver name='vfio'/>
      <source>
        <address domain='0x0000' bus='0x02' slot='0x00' function='0x0'/>
      </source>
      <rom file='/mnt/user/isos/vbios/2023/GeForce GTX 970.rom'/>
      <address type='pci' domain='0x0000' bus='0x04' slot='0x00' function='0x0' multifunction='on'/>
    </hostdev>
    <hostdev mode='subsystem' type='pci' managed='yes'>
      <driver name='vfio'/>
      <source>
        <address domain='0x0000' bus='0x02' slot='0x00' function='0x1'/>
      </source>
      <address type='pci' domain='0x0000' bus='0x04' slot='0x00' function='0x1'/>
    </hostdev>
    

 

And make sure to use nvidia latest drivers, not windows ones.
