Hello I purchased a Nvidia GeForce RTX 4090 GAMING OC 24GB from Gigabyte. I know I know.... it's a pretty new video card and not too many sane people are buying them. Let alone trying to use them in Unraid. I've been trying to passthrough this graphics card to my gaming VM but I only get a black screen when I boot. I can't find anything on the web or these forums about the 4090 and unraid yet. I've tried following 1) Followed Spaceinvader One's excellent tutorials which worked for my 2080 and 3080ti perfectly. 2) I tried the Techpowerup video rom for version 95.02.18.00.C1 which is my card without editing out the header and with the header edited out. 3) I got the newest version of NVflash64 just yesterday which allowed me to save the vbios rom directly from my card via a windows 11 build and tried the vbios rom as is and with the edited-out header. See attached Roms 4090 Original and 4090edited. 4) I have tried selecting and not selecting the graphics card and sound via Tools and system devices. 5) I've tried without a video Rom at all which seems to work for my 3080ti. 6) Tried building a new VM's using Q35-7.1 and i440fx-7.1 7) Tried Seabios and OVMF TPM I do see the bios screen and Unraid boot sequence. Unraid is showing the video card under system devices. I'm still getting a black screen in each of these configurations when I start any VM with the 4090 as the graphics card. I'm guessing that editing the Video ROM isn't working the same as the older Generation nvidia cards? Server is booting via UEFI Server version is 6.11.1 Main card is my Nvidia 2080 Secondary card is my 4090 and was my 3080ti. I can't even put the 4090 in the first pci-e slot because it's so huge. Tested VMs running windows 11 and windows 10 I'm wondering if anyone has had any successful passing through a Nvidia rtx 4090 yet? Maybe I just need to wait for a newer version of Unraid? I have attached my diagnostics which I grabbed while the 4090 was installed. Any help would be greatly appreciated. Thanks Indy 4090edited.rom 4090orginal.rom unraid-diagnostics-20221020-1758.zip
