Dickiescoob Posted March 12, 2018 Share Posted March 12, 2018 (edited) Good afternoon New unraid user here, convert from freenas, and so far I really enjoy it. I am having an issue setting up GPU passthrough. System specs: I5 with vtd enabled 32gb ram 6 4tb hdd w/ 2 in parity 1 ssd for cache 1 ssd dedicated for the vm only evga gtx 1070 gpu Everything is running really smooth except for the gpu passthru, I keep getting the error 43 when I look at the display adapter in device manager. I have tried the fix listed here, twice: I have also tried 6 different v bios, each with the same result.. My system sees the gtx 1070, but I am still getting that 43 error code. any tips or suggestions? this is causing quite the headache Edited April 6, 2018 by Dickiescoob Quote Link to comment
Warrentheo Posted March 13, 2018 Share Posted March 13, 2018 I had this issue at first with mine, was able to dump the vbios off the card, and add a line to my vm domain xml file to point to it, worked just fine after that... This video helped a lot... Quote Link to comment
Dickiescoob Posted March 13, 2018 Author Share Posted March 13, 2018 Thank you for that link, I have tried pointing to a modified bios.. trouble is, gpuz won't let me dump the bios. So instead I took the bios I'd 80.xxxx and found 6 matches on techpowerup. Modified each of them, and tried them one by one by modifying the VM xml to point to it.

tbrasser Posted March 15, 2018 Share Posted March 15, 2018 you can dump the bios from the unraid command line as per the video's instructions. Works for me, I passthrough my gtx 970 to windows VM and its the only graphics adapter that is installed. Quote Link to comment
Dickiescoob Posted March 15, 2018 Author Share Posted March 15, 2018 I must be blind, cuz I don't see anything in those videos about unraid command line to export the vbios.. one pulls vbios from techpowerup (tried that, no luck) & the other has a2nd gpu and pulls the vbios from gpuz when it's in the 2nd slot(p.i.t.a in my particular build to add a2nd gpu, even temporarily, but might result to that)Sent from my Pixel using Tapatalk Quote Link to comment

Don't straight copy/paste all my code, as it's just Gridrunner's example from his hardware. Notes: I recommend watching the video for context. Link also from my notes: https://www.youtube.com/watch?v=mM7ntkiUoPk Pre-req: need card in secondary slot to dump its bios start a VM using the card and activating. (Windows, drivers enabled) shudown vm lspci -v echo "BUS:ADDRESS:GPU.0" > /sys/bus/pci/drivers/vfio-pci/unbind cd /sys/bus/pci/device/0000:02:00.0/ echo 1 > rom cat rom > /mnt/user/yoursharename/graphicscardbios.dump echo 0 > rom I hope that helps. Good luck! EDIT2: I just noticed from your OP you have an EVGA 1070. What's the exact model? I'm asking because we might have the same card, I'm using the EVGA GTX1070 SC 8GB model. I've gone ahead and attached my vbios, if you want to try it. gtx1070.dump Quote Link to comment
Dickiescoob Posted March 16, 2018 Author Share Posted March 16, 2018 Thank you for that, I'll try that out this weekend. ?? My only issue is that my 2nd pcie has a SATA card for my 2 SSDs(VM/cache,) so I'll have to do some moving around to get this to work. I have the 1070 ftw 8gb, but I'll try your bios, just to see. Thank you:) I already have windows up, latest Nvidia driver's installed, all games and programs, so I shouldn't need to do this on fresh install, I hope lol Quote Link to comment

Dickiescoob Posted March 20, 2018 Author Share Posted March 20, 2018 Only thing left, I ordered a headless HDMI dongle to enable gamestreaming to my Nvidia shield ? Quote Link to comment

Dickiescoob Posted March 20, 2018 Author Share Posted March 20, 2018 I have a dual monitor setup with my regular PC, and the server I hooked up via DP to my 2nd monitor, but that still wasn't getting gamestream to work. I'm assuming since the monitor was being used on the HDMI source, and not the DP, that that was causing the issue. Found onanother thread people using headless HDMI dongles, so for$15, thought I'd try it. Quote Link to comment
Dickiescoob Posted March 30, 2018 Author Share Posted March 30, 2018 Well, my gpu appears to be working, as I can remote in and play games, however I cannot get game stream to work. I have disabled the firewall, anti virus, reinstalled geforce driver's several times, and followed the user trouble shooter guide on Nvidia, and still no luck. ☹️ Geforce experience shows that my system is capable, so not sure what I'm missing. Also have tried plugging a monitor into it and the headless dongle, but only get a black screen. Any thoughts or suggestions? Quote Link to comment

Disclaimer: I am using Proxmox VE but I had the same issue, In my case I had to plug in my Dummy HDMI plug then reboot the machine, setup Chrome Remote Desktop and check the Display Resolution after which I reinstalled driver and started moonlight client on my second machine and fired up Nvidia GeForce Experience in my VM and it seemed to do the trick. I use Parsec for gaming as I didn't have good "experience" with GeForce Gamestream. I hope this method also works on your machine as we have similar issue(I used 650 1GB UEFI patched card).
