So I just upgraded my Ryzen 1800X to a Ryzen Threadripper 1950x. It's got a terribly noisy cooler - which I could just replace the fans on (it's a Corsair H80i v2). I'd still have a slightly noisy pump, but the worst of it would be gone. Also, the temps I've had on both these systems seem either high, or I am misunderstanding them or they are being misreported in the system. Anyone know? This is on the Asus X399-A motherboard and with the 1800x is the Asus X370-prime motherboard. (See attached screenshot of temps). I assume the higher one is the CPU? This is using Dynamix system temp and the it87 stuff. Note these are idle temps. Sometimes gets to mid to high 70's and when under load (ie from gaming though only on 5 of the 16 cores) it gets up to about 85, maybe a bit higher. I did read somewhere something about Linux reporting it wrong and needing an offset adjustment? Anyone with experience on this? Thanks.

Well I did mine now. Basically just boot up and go with exception of CPU pinning and having to change a BIOS setting for the GPU passthrough. It certainly has a noisy water cooler with it though - (H80i v2). Am looking at whether to replace the fans or the whole thing - tempted to just do the fans if I can get some super quiet ones - damn thing is driving everyone in the house mad! I feel like going for a Noctua NH-U14S, there is something safe feeling about metal coolers being affixed to the CPU - I used to run them fanless even.

I'm about to do the same actually. Going from a Ryzen 1800x to a Threadripper 1950x. Both on Asus boards and expect it will basically be a boot and go thing being linux. I don't think the kernel saves specific parameters to the USB key for your motherboard / CPU, but that would be where it might go unstuck. Of course there are difference controllers for SATA to contend with and different hardware addresses, which while these should be auto detected, may require a config rejig. Did you do it already? How did it go?

I just followed the example above and deleted the network config, then rebooted, stopped the array, edited the Network Settings, where it lost access because it does that when you edit Unraid network settings on mine every time, then rebooted and it's working. Oddly, every docker image said it had an update after that, and the update downloaded 0B in ever case. But otherwise all good. Glad I didn't have a complicated network setup!

I have exact problem. Networking from the host works locally, but not across a router. The Virtual machines networking does work fine though. Only happened after RC6 upgrade. Edit - During boot I see that it is complaining it can't find Eth2, which I didn't know existed and certainly doesn't exist according to the GUI.

Installed this today. Worked first time no problems. I did notice the drives won't spin down again (which is a problem of RC4 that is fixed in RC5. Hopefully An update to something else comes soon.

I still have to add the code to get anything but x1 in rc5. Am I missing something?

I don't want this to be used for cache, it's for VM's and docker. Cache is a waste of an expensive enterprise drive.

OK, so feedback for the plugin perhaps, to default the Unraid behaviour. I only need to do this because Unraid does not support SSD's in an array, if it did problem would be solved. And I don't want to add it to the cache, as it's an enterprise SSD I use for dockers and raid which handles the IO of those things much better without killing the SSD. Unless you've got an idea I haven't thought of?

UD = Unassigned Disks? Then I guess it could be defaulted for unassigned disks?

I have an APC1500 tower model, which is exhibiting same symptoms. It works on USB mode minus the aforementioned fields. I 'assume' by poking around that if lsusb reports my device like this: Bus 005 Device 002: ID 051d:0002 American Power Conversion Uninterruptible Power Supply then the device string is like this: /dev/usb/hiddev2 But don't know the format in Unraid yet (just had a quick poke for anything in /dev that looks like usb). However with this, no other settings than USB work. Interestingly something I did has broken the option that worked which looks like it will require a restart to resolve which might have been throwing off my results. **Can anyone chime in at least with 'yes, that's where Unraid lists it's usb devices'?**

To work around it I created a new VM and pointed it at the disk I was using. Now works. Would be good to know for next time though.

Actually - I've just checked the CPU - there's no way it's running so it's definitely BIOS. Which I'm sure must be stored in a file somewhere, that is specific to that VM and needing to be replaced or something.

So my gaming VM stopped booting today. Conincidentally it was when I added some isolated cores. However disabling those did not help and other VM's boot fine. When I say it doesn't boot, what I mean is I can't see any screen via either GPU passthrough or VNC. Again, both of those work in another VM. I'm assuming the bios isn't loading for some reason but I can't seem to find where that might be stored so I can check / replace. Other thing I actually didn't try yet is seeing if I can prove it's on the network somehow after I've started it. It says it's started in the VM manager and there are no errors in the logs. Go figure. Any other ideas? Thanks.

For anyone else, that seems to have worked. So not quite out of the box, but at least simple to make happen within the xml.

I've found RC4 helps with Lag etc making it much more viable to game with - However at first attempt I am still showing up PCI Express x1. Does anyone know if I need to modify my vm xml config as well as run RC4, or should it just work out of the box? I'm guessing I need to add this to make it work? <qemu:commandline> <qemu:arg value='-global'/> <qemu:arg value='pcie-root-port.speed=8'/> <qemu:arg value='-global'/> <qemu:arg value='pcie-root-port.width=16'/> </qemu:commandline>

I've just installed RC4 again (having downgraded to isolate an issue (seems to have been memory). This patch definitely improves my Gaming VM performance on Windows 10. I found there to be some weird lag between the VM GPU / Mouse Keyboard which was making it nearly impossible to game. Seems to have gone away now, which is great.

Oh excellent so that was a wast of time then - lol. I don't get much time to be a geek these days, but it sure is fun playing with hardware again - I used to know everything and I now I know nothing! The principles don't change but the details sure move on.

I have today (apart from remembering how much I hate the windows long winded everything I have to do installation process", reinstalled the VM from scratch, Q35, dedicated SSD, and assigned it to the last 4 cores / 4 threads of the 1800X. I have also stopped anything else from accessing those cores, just to be sure. It's definitely running better. I have semi-evidence that SABNZbd was causing a bit of grief, but will leave that investigation for now. It was running on a Samsung PM863a which I am suspicious needs a firmware update - it's supposed to handle a lot of IO, which is why SAB runs from there, but go figure. So many things to think about with Unraid! My card is a 4GB EVGA 1050ti - linked here. It suited me at the time as it does half height slots and doesn't need extra power. I might upgrade it but it's remarkable how good it is to be honest. But I mention it just in case it helps with your EVGA situation. Actually I dumped an EVGA 710 BIOS while I was at it. Might be good for a Mac VM.

I just ran 3d passmark. The GPU runs OK at around 130FPS depending on the scenario, but what I notice is during the middle it will drop to less than 1 FPS. Also noticed, while typing the whole system pauses, then the typing catches up. There's something wrong with the way the VM is speaking to the host. So maybe it's not GPU passthrough at all.

Probably another aspect to the performance question is streaming. I haven't found that to be very good either. And the graphics quality goes down quite a lot. I assume there would be some good experience everyone has there too.

Thanks all, a fascinating discussion. Other than what @Warrentheo mentions above, I would not be sure how to know the passthrough is working - I definitely have the offical Nvidia drivers installed and the 1050ti card shows in my device manager, so should be good - I first used a hex edited downloaded rom, then dumped my own yesterday to be sure. From what you're saying it sounds like it's possible to get very good VM performance then. I might try the q35 setting next though I get stuck with some error about translating the PCI bus, then when creating a new VM I get stuck with a duplicate uuid. I'll sort that out - this is obviously getting off topic for this thread. I've run the 1050ti on bare metal windows (no Unraid) on this machine before so I know it's performance. It's definitely not the card causing this and besides for testing I've got all the quality on low (hence my query around what others are seeing). Something interesting is I actually see the mouse lag while the game isn't running just in bare windows - not a lot, but sometimes a bit - at a guess I'd say disk I/0 is lagging the system which makes me think @Warrentheo's suggestion of converting to SCSI is a good idea. And it's when I'm using the mouse (turning character left and right) that I see all the screen lag / jumpiness - going forward and back doesn't seem to do it for some reason - I guess it redraws more sideways, or it's interrupt based problem. There are plenty of cores available with Ryzen 1800X , it's on an enterprise SSD, and it has dedicated 14GB of total 32GB memory at present. Should be good. So keeping on topic - Performance related enhancements, hyper V I assume should be on also? Seemed to make things a bit better when I enabled it.

Can someone chime in on what kind of games they're playing which are good performance? I'm running the beta (yes I know but it works on bare metal OK) of the Division 2 and getting all sorts of GUI lags that make it a bit problematic. Much like when the fps and sync rate is out watching a panning scene on TV, but worse. It's playable, but not very enjoyable. Is it too much for Unraid? Should mention Nvidia 1050ti from EVGA, dumped my own bios, but it actually seems to run the same without the bios for some reason. On that, I just renamed the .dump file to .rom - I assume that's all good.
