ADVNC Posted March 20, 2023 Share Posted March 20, 2023 Hello, my question is both very simple and yet I can't find any solution....I have a GTX 1080 8gb from KFA2 and it's impossible for me to use it on my passthrough server! (Error 43) Is this card simply compatible??? Quote Link to comment
denishay Posted March 20, 2023 Share Posted March 20, 2023 stupid questions, but.... you do have another GPU at all on this setup? If you are trying to pass through the only GPU, the system doesn't have any left Quote Link to comment
ADVNC Posted March 20, 2023 Author Share Posted March 20, 2023 (edited) Thank you for your answer ! My motherboard is an ASUS Gaming Motherboard – Z170 PRO GAMING and indeed there is a graphics chipset... My VM works but if I try to put the drivers for my GTX 1080 the VM crashes and I get code 43 Edited March 20, 2023 by ADVNC Quote Link to comment

zeus83 Posted April 5, 2023 Share Posted April 5, 2023 Hi, I owned lots of GTX 1080 and none of them was incompatible. I'd say with GTX 1080 / GTX 1080 Ti I had zero issues on passthrough. Did you follow the instructions on GPU passthrough precisely ? Do you have these lines in your VM configuration ? <features> ... <hyperv mode='custom'> ... <vendor_id state='on' value='1234567890ab'/> ... </hyperv> <kvm> <hidden state='on'/> </kvm> ... </features> Also if this the only GPU in your system try putting this onto boot line: video=efifb:off Quote Link to comment

Please review the great instructions for GPU pass through here: Take notice of the BIOS changes that are necessary. Take notice of the Custom ROM/DUMP. https://www.techpowerup.com/vgabios/?architecture=NVIDIA&manufacturer=KFA2&model=GTX+1080&interface=&memType=&memSize=&since= Take notice of the Binding needed.
