Wow - this thread is a monster, and I have just gone through hours and hours of getting a simple Nvidia GT710 passed through to a Windows 10 VM. I'm pretty experienced with building VMs with GPUs, so this came as a surprise. I certanily won't buy another HP for using with Unraid! In the end, here is what I recommend which got me working. For clarity, I have a Proliant DL360e Gen 8 running Unraid 6.8.3 Before you do anything, follow the instructions from 1812 to obtain the HP Proliant build of unraid. Seriously - don't waste time on RMRR or Operation Not Permitted (what I got). Try the HP Proliant build first as it sorted everything out for me straight away at the Unraid level. Doing a manual patch when you want to upgrade in the future is nothing compared to the pain if you don't use this IMHO. https://github.com/AnnabellaRenee87/Unraid-HP-Proliant-Edition Set your boot options in Syslinux configuration (replacing the PCI devices where necessary) : pcie_acs_override=id:10de:128b,10de:0e0f vfio_iommu_type1.allow_unsafe_interrupts=1 (possibly you don't need the ACS override - I haven't dared take it out as I have a working solution) The main problem I experieced was the code 43 error in Windows. No matter what I tried, I could not find a solution, until I read on the forums about GOPupd. Firstly I didn't have much luck until I did the following... Installed the GT710 in my Windows 10 desktop Ran GPUZ to export the BIOS (my model was not available at techpowerup). Used GOPupd to inject the UEFI code into the bios file (https://www.win-raid.com/t892f16-AMD-and-Nvidia-GOP-update-No-requests-DIY.html) Used HxD and the instructions from SpaceInvaderOne to remove the extra lines at the top of the rom file. Copied this rom file to my Unraid box. Moved the GT710 back into the proliant Added the GPU & the Sound Card portion into the VM using the new rom file Once I had this ROM file, it was all good. I can operate the VM as much as I do in my other servers with GPU passthrough. No restrictions or issues found yet. Thanks to all contributors on this forum and elsewhere, or I would have been lost.
