February 27, 20197 yr Thanks to @paperblankets for pointing me in the right direction! For anyone who couldn't passthrough a single Nvidia card, and you already tried techpowerup's ROMs - dump your own card's ROM and try again. _____________ Unraid noob here Running Unraid 6.6.6 I'm trying to passthrough a 1070ti to my Ubuntu VM, which is installed in slot 1. I've installed Ubuntu at least 10 times and tried multiple combinations of what I've read online to get this to work. However, none of the following has worked for me. I've tried installing Ubuntu with VNC first, then switch to the GPU. I've followed this SpaceInvader's video. I tried this. Quote echo 0 > /sys/class/vtconsole/vtcon0/bind echo 0 > /sys/class/vtconsole/vtcon1/bind echo efi-framebuffer.0 > /sys/bus/platform/drivers/efi-framebuffer/unbind Switched the Unraid USB from UEFI to Legacy Tried both OVMF and Seabios I've also tried adding the 1070ti to the Win10 VM, but that didn't work. The VM would start but all my monitors were blank. ***I cannot move the GPU as my system is custom watercooled.*** My system: Quote Model: Custom M/B: ASRock - X399 Taichi CPU: AMD Ryzen Threadripper 1950X 16-Core @ 3400 HVM: Enabled IOMMU: Enabled Cache: 1536 kB, 8192 kB, 32768 kB Memory: 32 GB (max. installable capacity 512 GB) Network: bond0: fault-tolerance (active-backup), mtu 1500 eth0: 1000 Mb/s, full duplex, mtu 1500 eth1: 1000 Mb/s, full duplex, mtu 1500 Kernel: Linux 4.18.20-unRAID x86_64 OpenSSL: 1.1.1a I have a Windows 10 VM running with a passed-through 1080ti as well, and I had no problems with that machine.

February 27, 20197 yr The VBios you use, did you copied it from your card yourself or is it downloaded from TechPowerUp? Did you removed the Nvidia header from that dump? Without removing this, my VBios never worked for a 1050ti or an 1080ti.

Did you removed the Nvidia header from that dump? Without removing this, my VBios never worked for a 1050ti or an 1080ti. I downloaded from Techpowerup. And yes, I removed the header from that dump. In the video, he left the file extension as ".dump" but it should be ".rom", no?
February 27, 20197 yr Hi @kalfun I could not get any bios from techpowerup to work for me even after custom modification. My card is a GV-N1070IXOC-8GD, there _are_ bios's uploaded to tpu for the card, but the only dump I could get to work was the one I pulled myself, and modified myself. I have seen a few other people online report similar things, but I have no idea what the cause is. My vm configuration ends up containing: <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/gpudumps/GeForce GTX 1070 Mini ITX OC 8G/modified bios/193322.rom'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x06' function='0x0'/> </hostdev> I don't think I have shared anything that was not listed above, but my configuration is close to yours, so hopefully something in here is helpful. Good luck!

That's exactly what the issue was! I had to pull the dump off my own 1070ti for it to passthrough! Thank you so very much! Edited February 28, 20197 yr by kalfun
