DigitalStefan Posted November 26, 2017 Share Posted November 26, 2017 Hi Steve, I've concentrated my efforts with OVMF, although I did try to fire up a few Seabios based VM's, with zero success. I've just spent the last 20 minutes thinking about buying PCIe risers and a sacrificial Nvidia GT710 or other basic adapter, just so I can pass through the 3 GPU's that I actually care about. It will be a cheaper option than changing motherboard and CPU. That being said, my board and CPU do need to get replaced at some point. If I push all cores on the CPU, the system powers off. Already replaced the PSU, but I guess it's probably capacitors that are a bit too old on the board now, or a MOSFET or two are a little unhappy. Quote Link to comment
steve1977 Posted November 26, 2017 Share Posted November 26, 2017 Mmh... How do you access the three GPUs? Do you have screens attached or using some form of remote desktop? Does the issue only happen if you run all three VMs in parallel or also individually? I still face some problems when running two Win VMs in parallel, which I don't face when not passing through the GPU. If I may ask, what are you using three GPUs in paralle for and do you have experience with Gamestream? Quote Link to comment
DigitalStefan Posted November 26, 2017 Share Posted November 26, 2017 No displays attached. I've tried combinations of multiple GPU's attached to a single VM and separate VM's per GPU. I always hit a problem trying to pass through the first GPU - i.e. the one unRAID itself initialises. I'm RDP'ing into the VM. Currently have one Win 10 VM with 2 GPU's attached to it. The 'main' GPU is just sitting in the machine, doing nothing useful. I'm cryptomining with the GPU's, running Plex, using the box as a NAS and also running Server 2016 Essentials with a separate Win 10 VM for a bit of dev work. As long as I don't thrash the CPU, this machine is happy with month+ uptimes. If this were anything other than a "let's see what we can do" box, I'd probably have replaced it with a Xeon machine from a few generations ago. Quote Link to comment
ceb0610 Posted January 8, 2018 Share Posted January 8, 2018 Do I need to restart unraid if I am switchng a graphics card from one vm to another? I have Windows 10 VM running with a GTX960 passed through. The performance isn't what I was hoping for so I created a windows 7 VM that is much snappier, but I can't get it to boot with the GTX960 from my Windows 10 VM passed through (that is with the windows 10 VM off). The VM icon, in unraid , will turn green but the screen won't turn on and one core will e pegged at 100%. Any help would be greatly appreciated.System info below. unRAID 6.4.0-rc7a Dual Xeon E5-2680v2 32GB RAM GTX960 2GB Quote Link to comment
Henry Thomas Posted February 11, 2018 Share Posted February 11, 2018 (edited) I am stuck on the infamous Error 43. I had the system working WITHOUT error 43 somehow yesterday but the entire server would crash. First I'd see a blue screen "internal video scheduler error" then during the dump the entire Unraid server would crash - and not reboot automatically. So I fiddled a little bit with reinstalling the driver, running that sfc command as admin cmd ... to no avail whatsoever. Then I'm back to Error 43. I have tried Hyper-V on and off, and I have tried SR-IOV on and off IOMMU of course is enabled. I did dump a rom and am passing it through successfully (if I make a typo or whatever I just get a black screen as opposed to at least move around in WIndows.) I don't know what to do next This is a Ryzen 5 system with Nvidia 1050 Ti Edited February 11, 2018 by Henry Thomas Quote Link to comment
tjb_altf4 Posted March 4, 2018 Share Posted March 4, 2018 Is anyone running a single card passthru setup also able to drop back to unRAID console once the VM shutdowns and releases the GPU? Curious if this is possible. Quote Link to comment

cablecutter Posted March 6, 2018 Share Posted March 6, 2018 Hi All, First - I love your videos and think I've watched almost every one. There's no way I would have Windows 10 up and running without your help! GPU: AMD RX 560 4GB (Gigabyte) v2.0 Just posting to see if anyone else has had graphical glitches in games and trouble with the HDMI audio when passing through this card. I have dumped the rom via GPU-Z and added it to the XML, however this did not have any effect. I have a more comprehensive post here: Best, Rob Quote Link to comment
Starlord Posted March 12, 2018 Share Posted March 12, 2018 Stuck with error code 43 passing through my 1080ti with self dumped vbios following the instructions in the first video. Disabled hyper-v with no luck. Also tried modding drivers to no avail Also tried editing the XML to include the kvm hidden state and vendor ID override. Quote Link to comment
Starlord Posted March 12, 2018 Share Posted March 12, 2018 KVM also spits these errors out Quote Link to comment
steve1977 Posted April 6, 2018 Share Posted April 6, 2018 I’m also stuck with error 43. Whats really weird is that i can actually pass-through my primary nvidia to the win10 vm. i didn’t do the bios dump and i don’t have on-board gpu. so, i’m supposed to get the “black screen” (and did so in the past). now, i can actually pass through my only gpu. is “error 43” the new “black screen”? any help appreciated!

ksignorini Posted April 9, 2018 Share Posted April 9, 2018 (edited) Can this post get stickied? Without this post, I was at a huge loss after switching from AMD to NVIDIA. Please sticky this post! ...and thanks @gridrunner for the great videos and information you provide the community! Edited April 9, 2018 by ksignorini Quote Link to comment

ren88 Posted June 18, 2018 Share Posted June 18, 2018 i cant passthrough 2 different graphics card with 2 different vms of windows 10 and hackintosh, i get the error, here is the diagnostic file Execution error Requested operation is not valid: PCI device 0000:02:00.0 is in use by driver QEMU, domain Windows 10 brun3tte-diagnostics-20180618-0628.zip Quote Link to comment
Cogito Posted September 16, 2018 Share Posted September 16, 2018 My setup: Zotac GT710 1GB in primary slot, my only gpu in this system Asus X99-WS/IPMI (no onboard video) I'm trying to pass this GT710 to a Win10 vm. IOMMU looks perfect on this motherboard, i have an isolated group with only my gpu and its audio (which i'm passing too). I dumped the bios and edited its header, but i get black screen on vm startup and the dreaded error 43 (the os boots fine, i can see everything else working through a Remote Desktop session). I tried both Hyper-V on and off and i tried a techpowerup vios too. I read something about the GPU not dumping correctly its vbios (or kvm unable to use a different vbios, can't remember which) if the card is plugged in the primary slot. Could someone give some clarification on that? Do you think i have no chance in passing this GPU with the right vbios without using a second card? Right now i'm saving money for a proper gaming gpu and i will try to pass that once i have two cards to experiment with, but i would really like to have my vm up and running with a single gpu in the meanwhile. Thank you very much for your efforts, i do really like the idea of keeping this vbios list. 1 Quote Link to comment
Wuping Posted September 21, 2018 Share Posted September 21, 2018 Hey guys anyone having issues with passthrough with update 6.6.0. I updated and none of my VM's with graphics passthrough won't work I get the Unable to power on device, stuck in D3 error. When I revert to 6.5.3 the VM's work just fine. Quote Link to comment
naik Posted November 15, 2018 Share Posted November 15, 2018 Hi guys, before I try this out I wanted to ask if doing this would still allow me to use the graphics card for all VM instances that I pass through the gpu on. And would Plex on Ubuntu still do hardware transcoding with the graphics card when I do this mod? Quote Link to comment
bastl Posted November 15, 2018 Share Posted November 15, 2018 @naik You only can run 1 VM at the time using the GPU. You can configure multiple VMs using the GPU no problem, put you can't run them at the same time. Quote Link to comment

ToXIc Posted November 24, 2018 Share Posted November 24, 2018 Hey all i'm trying to get my GTX1050 to work trough my Win10 VM but i cant shake the stupid Code43. The VM runs fine i can get video np with VNC set and with google rdp when the GPU is used. I've done soo much googling over the past two days i'm exhausted. I've done the folowing: Turned off Hyper-v PCIe ACS Override setting enabled VBIOS edit and XML Uninstalled the driver and installed ver 378.78 and set the hidden state in the XML I know ive done more just cant think of it at this point.. Any help is greatly appreciated. unRaid ver 6.6.5 Quote Link to comment
steve1977 Posted November 24, 2018 Share Posted November 24, 2018 Do you have two GPUs? It's weird, but I never got it to work with two GPUs. When I removed one, it worked ok. Quote Link to comment
naik Posted November 24, 2018 Share Posted November 24, 2018 (edited) Is there a way to make sure the VM is using my GPU for Plex h/w transcoding and not my Xeon? Because the whole reason for this gpu was to offload some of the media workload to from my CPUs. Plex doesn't show which device is doing the transcoding.

I'm trying to pass-through GT1030 without success... i have one Asrock J4105M (uefi) + Gt1030 (uefi). I use the same process of that guide, i dump my bios and inject it at VM. E get black screen for 1-3 secounds, and after goes back to terminal unraid. Sometimes get terminal unraid window with strange color squares. There are any possibility to fix it?
