I am trying to passthrough my GTX 980 since a few days. I've tried a lot of different solutions and so far, none of them gets me over this cursed error code 43.
I'm running Proxmox VE v7.1-7 on the following machine:
Here is my current VM configuration (I tried several other configurations - none of them worked):
Here my Grub configuration
I went through several recreations of the windows VM and a couple of re-installation of the Proxmox VE, so far and I followed instructions and guidelines from:
Lastly, I checked on this forum and I tried to follow the ROM patching approach described in the post:
https://forum.proxmox.com/threads/nvidia-gtx-1050ti-error-43-code-43.75553/#post-457290
Even though this approach is claimed to work only on 1xxx series and not on 9xx series, I tried in any case by patching one of the rom files at this address: https://www.techpowerup.com/vgabios...rface=PCI-E&memType=GDDR5&memSize=4096&since=
None of the approaches I tried has worked and I honestly don't know what else I can try...I have no clue of what is wrong with my hardware or with what I do.
This post is my last chance.
