Hi all,

 

I've been working on an Intel-based Unraid system powered by an i7(split in half between the windows VMs) and an MSI Gaming Pro Carbon.  Recently I decided to switch to Ryzen, because I can't keep my hands off fun new toys, and went the way of the 1700x and MSI x370 Gaming Pro.  MSI has been good to me so I stuck with them.  Still, no matter what I try I can't get gaming performance anywhere near what I had on Intel.  I'm hoping some enthusiasts can help me demonstrate the full power of this battle station (Rogue 1's finally on Netflix):

 

Current Specs:

2 x GTX1080s

32GB of ram @ 2666 (since Ryzen apparently voids warranties over that, 14GB per VM)

1700x (Tried 2 or 3 physical cores each, with hyperthreads)

MSI x370 Gaming Pro (BIOS built 6/22, latest as of this post)

3 gaming monitors tried, 4k60hz, 1440p144hz, and the classic 1080p60hz

 

I ran a windows baremetal OS to verify functionality of the hardware.  I've used Ryzen Master Utility to disable cores to match Unraid as closely as possible, dropping the system down to 4 and 2 cores.  Everything is still flawless and I love it.  However, in Unraid's VMs, games can vary in fps between 140-15fps in a matter of seconds.  Witcher 3 and Doom are outright unplayable, @ 15fps each.  I've noticed some amount of video-audio de-sync as well, despite isolating cpus from Unraid as recommended and enabling msi, but that's a minor issue compared to gaming.

 

In terms of fixes, I've tried almost everything outlined in these posts: 

Page 14 is where they recommend NPT=0.

As per other users, I ran into severe issues with NPT off, mainly performance degradation and crashing, despite swapping to Q35.  I wasn't entirely sure how to disable CPU pinning, so I've been trying to figure that out, but I'm not sure how 2 VMs would even survive if I had the system configured in such a way.  

 

TLDR:  My build works fine on baremetal, even with only 2 cores.  I've scoured the forums and the 23-page-long Unraid living document above, and tried most all solutions but disabling CPU pinning.  I'm hoping I've missed something, and that a kind soul will show me the light.  

 

If you have any recommendations, please don't hesitate to present them.  I'll be trying to keep this post updated with tested configs and results.

Try upgrading to 6.4.0-rc7a and seeing if there is a difference in performance.  

Wow, 6.4.0 just dropped.  Great!  I'll post once I find out if this works.  The other thing I want to try again is tinkering with disabled NPT, but to prevent the terrible booting that results.

No, only another release candidate in a string, leading up to the release of 6.4 final. We're not there yet.

Tried rc7, got nothing on i440fx 2.9.  Will Try Q35 next.

Weird issue.  Tried Q35, couldn't get the OS running.  It kept trying to run the install disc.  Stripped out the install disc and the OS still isn't coming up.  The other windows VM (for the second gamer) had to run a disk check but it came out fine in the end.  I haven't fiddled with it.  As for the first VM, it doesn't show the OS on i440fx either.  It's like the data on the img was blown away.  

Attempting to boot the questionable img from the second PC resulted in it failing again.  It looks like the img is empty.  I may have left the VM on overnight, and it might have crashed, but this is something I've never seen from Unraid before.  Either the stability issues over time or the crashing and burning an img

Now no img is safe.  I can't get a boot from any VM, including from backups, even after restarting Unraid.  It looks like this might be rc7-related.

I wonder if you have corruption on the drive hosting your VMs?

 

uou should upload your diagnostics (Tools->Diagnostics) zip file so that others can see if they can spot any issues with your system.

My backups are on separate drives.  I doubt both drives are bad.  However I can take the diagnostics and post them.  I hate to be that guy who blames the newest release, and I hope I'm wrong.

Here they are.  I may pull the flash drive and check if it needs recovery next.  Swapping drives and img files didn't help

Reverting to 6.3.5 did nothing.  I really don't want to have to reinstall Windows on these VMs again.  Configuring the environment after install takes forever.

Reinstalled windows VMs would not boot after creation.  It seems my VMs are being configured at some point where they can no longer be readable.  This is occurring on stable 6.3.5

Any update on this?

Is Ryzen 1700X with 2 Gaming VM‘s stable with Unraid 6.5.2 ?

Thanks in advance!

Hi Melo,

I guess it's on me that the thread died on a negative note.  All good news, Ryzen showing no issues for me on the listed hardware.  If you need help with the config PM me, but I'm still using it as my primary PC.  Check my history too, some good threads there.
