I only have one 16x slot left. I have 2 16x slots and one slot
will be used by passthough of a Sata controller to a FreeNas kvm.
Therefore I am trying to use a single card. Passthrough of a secondary
card works already, however I want to remove the second card.
I could also buy a new Motherboad, h

This method did not work for me with a 1080 GTX. I reseated the GPU in PCIe lane

Considering how difficult passing through a primary adapter is I suggest

You can obtain a fanless low profile model for around $20-$30 or so I

Alternatively if you want to play games but are strapped for c

"-device
vfio-pci,host=01:00.0,multifunction=on,romfile=/mnt/nvidia_bios.rom"
However when using rom-parser it shows "Error, ran off the end"
