While I've followed probably many guides on how to create a rom/dump file, I've always had mixed results. Recently i updated my Mobo bios and my passed through vm didn't show up. Then started the struggle. I created many machines over and over again, sometimes the video wouldn't passthrough, other times the infamous error 127, other times i got video but my mouse and keyboard wouldn't work. On this occasion I took the help of vnc to install the windows and then when I tried to passthrough the video card, it wouldn't work. I'm not a hater here, I've been on the platform for about a year now, but my gaming rig is suffering. Rest of the features are great and I've no complaints. Also just a side note. I have a 3600MHz ram (4x16G) and certain times while trying to run the vm I've had reboots. Is 3600 (docp) acceptable? Done chart showed AMD being allowed 2133. Hardware Mobo Asus dark hero x570 Amd 5900x Corsair 3600 Xpg nvme Rog Strix 3080ti Quadro p2200 Razer Naga Trinity/hunter elite MSI mag27 qrf-qd Honestly I'm very much in a sinking ship where I might try PopOS to run games or maybe switch to windows barebones to run the gaming rig. I don't want to but this is frustrating as one would imagine. Please help. Thank you.

I'm able to passthrough windows 10 on my Quadro P2200 with 'multifunction', but I have issues with Asus Rog Strix 3080ti. Windows seems to be the problem for this. I am able to passthrough 3080ti on Linux distros with just the 'multifunction' and reassigning the bus and function. For 3080ti passthrough on windows I have failed using • multifunction • Vbios extract through script (spaceinvaderone) gave me a 200kb file and no joy • nano go to add code (I think it was to unbind the gfx card) • Vbios hex edit after downloading the vbios from techpowerup. Spaceinvaderone says you can use a similar bios and I couldn't find the OC bios, so I downloaded the LC bios of the same card. It's a 2000kb file (seems very big) and I could find the text 'video' twice when I searched on the hex editor. Removing the text above the first instance gave me a file of 1800kb Removing text above second instance gave me a file of about 1000kb Preserving text of the file from first header to second header gave me a file of about 900kb All of these don't work and look bigger than the vbios extracted from the card via script. Any further help would be appreciated.

Bump. Anyone?

My plan was to build a gaming rig with a plex server. I got the Asus Rog Strix 3080ti OC about 10 hours back. Added the PCIE cables installed the GPU in PCIE 16_1 on Dark hero and shifted the P2200 (Plex exclusive) from 16_2 to 16_3 (chipset). While waiting for the gfx card my Monitor died and right now there is a monitor shortage where I live. I don't want to buy a cheap monitor now and a 1440p 144Hz later so I tried to connect the computer to my receiver connected to a 4k TV to start. Using HDMI cable for video out. Able to access bios and the initial server boot is also displayed. Deleted a few VMs to make them compatible with the new GPU since I realized which linux distros I'll actually be using with GPU and others I'm happy with VM. Also wanted to reshuffle vdisks sizes. After seeing a lot of @SpaceInvaderOne videos I used the latest one from December 2020 where the vbios is dumped to a location on the mnt\disk\isos\vbios I'm sad to report that I couldn't get it to passthrough. I experimented with OVMF/Seabios and i440fx 5.1 and Q35 5.1. I'm unable to get the video output. I even selected the audio off altogether to make only the VGA part of GPU functional to start and look thereafter. I'm now planning to download the vbios from powertech, remove the headers and try to load that. Till now the screen has been going from no signal to blank. If I try to load an VM without a bootable drive I'm getting the "No boots le drive" error on the screen suggesting once more that the GPU is getting passed through. I think the problem is with the unraid, 3080 ti and video signals. I had made a VM of the P2200 a few months back and didn't face a lot of issues running that along with sound. WHat do you guys think/suggest? I'll probably look at the system again in about 6-8 hours. I'm ready to provide any other things that might be required.

So I'm just wondering (and quite honestly it's just wondering) about motherboard, case and GPU manufacturers are all over the place these days. Currently I own a Dark Hero x570 and if I were to populate the top PCIE slot with a 3 slot (very common 30x0/6x00) I'd be choking it up if I want to populate the second PCIE slot into a x8,x8 config. The funny part is that Asus decided to put a M.2 slot between the CPU and the top PCIE and in my Lian Li O11 XL the graphics card would screw into the second slot of the case and the top most slot is "wasted". Similarly I could want to move my P2200 from the bottom most x8 slot (chipset) a slot or 2 lower since I really don't need any output from it and kinda declutter the hardware being attached to the Mobo. I have seen PCIE extenders and could definitely use them, but that would be like cutting my hair with a sword. Is there like a just a slot or 2 up/down kinda attachment for the PCIE. Im sure I'm not the only person wishing for such a thing and I do understand the whole PCIE4 not playing very well on extenders, but still, where can I start looking and what am I looking for?

Yeah. That x4 is reserved for the P2200 which chills transcoding files for my family accessing plex. It's a monster, I mean I'd buy that even if I had a threadripper at hand. Thanks for your help, really appreciate it.

Thank you for the reply on the heat problem. I was on similar lines but honestly I didn't think of the middle slot to vertical mounting.😬 What about the x8 and x16 bandwidth? Or I shouldn't be too bothered since it's PCIE4 anyways?

Anyone? Please.

Hi all. Built my first server about a year back and was able to get a P2200 before things went "very" crazy on the costs of even the most useless GPU. Could get most of the components I needed from Asus ROG (you can call me a fanboy). I have a couple of issues and doubts. X570 Dark Hero Amd 5900x NHD15 with 1 fan Corsair vengeance pro 4x16 CL18 3600MHz. Lian Li O11 XL Lian Li 120x9 fans (the ones with interconnects) Nvidia PNY P2200 Quadro (transcoding) I'll start with doubts. I was planning to run this system primarily for Plex server and a dual gaming rig. The 2 gamers 1 PC lookalike. While all OSs are set and installed and able to pass through the P2200 for both sound and video,I think I'll pretty much manage that. Now the question is cards. I'm planning a triple monitor setup where it could be broken into 2 systems and 2 people can game with a monitor each. @SpaceInvaderOneexplained most of it beautifully in his videos. The thing is when and if I get hold of the 3080. Personally I'd like Rog Strix OC 3080 + Strix 3070 or a ROG Strix 6700. I mean I hope you get the point. 2 beefy gfx cards, one capable of 5k (triple monitor) and another capable of 2k. The layout of the PCIE slots is standard sized. 2x16 1x1 (infinity) and 1x16. Obviously I'd want to populate both the heavy gfx card in the top 2 PCIE and run them at x8+x8 for dual gaming. The x16 slots are separated by 3 slots and the gfx cards are the same. The bottom x4 slot will get the P2200. Am I looking at a thermal meltdown? Also when one of the x8 gfx card is not in use (VM shut down) will the remaining card become x16 again for triple monitor? A few more questions about the RGB, but right now they sound very puny. Thanks.

Thanks for the reply. And yes I think a few more things I realized were that virtio lan drivers are limited to 500mbps which is not too great to transfer data. For plex etc I think it should be fine, since most movies are under ~100 mbps, so I do have a lot of headroom. You mention setting VM on cache. What about unassigned devices? Since I have a 2tb nvme and currently its a single drive won't that make better sense? I might be wrong here, but I'm looking for ideas and options. Also I did see a video where space invader passes through a NVME, partitions it and uses one part to boot his VM. What he doesn't show is what happens to the XFS formatted part of the drive? Is it available to the server/dockers even with the VM running? I would assume so but then again it went uncovered in the video. I guess I'm ready for the next logical step into my journey of Unraid, where I find out how NVME suits me best. One final question? To 'move dockers' on NVME moving the app data folder (in the "Edit" page) of the docker to NVME will suffice or do I need to do something more?

So the pool is now compete (for now) 4x4tib disks with one as parity is running successfully (diagnostics attached). First things first... Oh man I miss the NVME VMs. My windows 10 VM took like what seemed an eternity to load and cpus were idling at about 10% for 4C/8T config for the VM. I know when the same VM was on the NVME they were RED (100%) during startup and shutodwn. Another thing I noticed, the data transfer speed has reduced. When I was transferring from TrueNAS to Unraid (1 nvme array) I was hitting 100-110 MBps which is the theoretical bandwidth of a gigabit and though I don't remember using a laptop on wifi to connect the 2 was also giving about 10 MBPS write to Unraid. With the spinners, the performance has taken a big hit (which I'm still not understanding completely). My VM speed, though it started at about 32MBps went to about 50 MBPS and now is loitering at about 10-15MBps. I honestly thought that the 1GBps gigabit would choke before the 6GBps sata, hence the speeds would always remain about 100MBps. Using the laptop in between makes it hit ~2MBps.

YOU MAY IGNORE THIS AND MOVE TO THE NEXT POST. So I have finished replacing my NVME with a spinner and I am now adding two more disks into the array (its still rebuilding) with 1 disk as parity and 1 as Data. I've left the NVME unmounted and my TrueNAS server is mounted to provide data for various dockers (eg Plex). In the long run (short term goal) I want to shift all my vm and jails (dockers) to my Unraid box since that server is now ancient and can barely transcode x265 (4k>720p) and TrueNAS lacks gfx card support. In the long (long term) I might buy new HDDs and shift all the files to Unraid too and go holey moley on it. One of the disks (being old) had some unrecoverable errors I think despite only showing 4 errors on the pre clear read test (SMART), so I replaced it with another one lying around. Like I said, it'll mostly never go into very rigorous server use than a PC use. I mean I could have run the Windon'ts Server edition, but I'm personally not a fan of theirs. That's why back in the day (2014) I chose FreeNAS despite it's heavy requirements. I'm not going to say which is superior to which but definitely loving the flexibility of Unraid so far. If you find this unsuitable I shall upload another file after the rebuild completes. unraid-diagnostics-20210310-1839.zip

Thanks. Lemme get my array properly populated and I'll be back. I think it should take about 24 hours give or take.

So I guess all went well. Thanks @trurl. image attached. I managed to create a parity. Took almost 8 hours to do so. Now I've replaced the nvme with a spinner and seems like things will build over the next few hours. I did have a few doubts which I need help with. I did find a few 2019 posts to this topic but not sure if they are still relevant now. How exactly do I 'make' the dockers/plugins/VM go to nvme? Move the app data of all to the NVME and have mover shift them back to data disks? That would involve me mounting the NVME as a cache and moving app data to the nvme. Would I have to repeat the process every day since I think mover does clear out the cache? Would that also mean that for a few minutes/hours the dockers/plugins would not be available since the appdata path would be pointing to a blank space? I also saw a video from space invader who does pass through the NVME to a vm to gain speeds. He made the NVME as the boot drive and the virt disk as a data disk. I liked that idea too. Could I use one (2tb) nvme to handle all of the VM/dockers/plugins? I know on read and writes alone, the 1gbps connection in my house with orbi ac3000 (887mbits backhaul channel) will be filled even before it can make the spinners sweat. Maybe I'm asking a lot, but then I guess I'm expecting a super fast VM/plex without breaking my bank balance.

Yes I understand not a raid 5, its more of a one disk failure tolerance. Thanks for the reply.
