I recently build a new UnRaid server with the following relevant parts:

• Motherboard: ASRock X570 Phantom Gaming 4 AM4 Motherboard (link)
• CPU: AMD RYZEN R5 3600 (link)
• RAM: Team T-Force Vulcan Z 16GB (2x8GB) DDR4 3000MHz (link)
• PSU: Thermaltake Toughpower GX1 Series 600W 80+ Gold (link)
• GPU: MSI GeForce GT 710 2GB GDDR3 (link)

 

I am running ~20 Docker Containers and 1 headless Debian VM.

 

At least once a day the Server appears to lock up, and I am unable to access it until I perform a hard shutdown/restart.

I haven't been able to isolate the issue, I originally thought it was maybe Sabnzbd using the cores the VM runs on and maxing it out causing a crash, so I isolated CPU 5 & HT 11, then have the VM just using those. Additionally I read some people faced issues with VMs when the Cache was not XFS format, so I changed to XFS format on my Cache.

There is plenty of free CPU power and RAM as shown in the screenshot below.

 

 

That didn't seem to help though, so I connected a monitor to the GPU and it displays the following screen when it crashes:

Is this the C-State issue I have seen mentioned? I thought that was meant to be resolved with these newer Motherboards/CPU?

 

try to change the Power Supply Idle Control in bios to typical current idle, I'm fine with that using x470+3700x

Will give it a look! Hadn't noticed that setting. Thank you!

You shouldn't need it for anything later than 1000-series processors, but it won't hurt. In case you struggle to find it it's usually at Advanced -> AMD CBS -> Power Supply Idle Control in the BIOS. Give it a try and report back to let us know if it makes a difference.

So despite the Motherboard stating it doesn't need updating to support Ryzen 3, and the C-State issue apparently not existing in Ryzen 3 I believe that is exactly what it was. I have updated the Motherboard now and haven't faced any issues, surprising that was required considering the board came out mid this year I believe?

 

Regardless - glad it is now sorted. Has been stable for ~5 days now and enjoying the significant power increase over the old HP Microserver N54L!

Sorry for the necrosurrection. But what exactly did you change to make it stable / work properly? The power supply control? If that's just for 1000 series how did it work for you?

It's not just for 1st gen, many reports that it also helps with 2xxx and 3xxx, not sure about 5xxx.

I had to change idle control and C-states on my 3900x for it to be stable.

My ryzen build kept freezing daily. 2700x. Currently on a 7 day uptime streak after rolling back Unraid to 6.11.x 

 

Go figure! 

Best practices for all Ryzen -

• Don't manually overclock (allow the CPU to handle it)
• Set memory timing based on this FAQ.  Mind the Single/Dual Rank and the number of DIMMs used.  (Also don't go by the marketing speed, but see what the true native speed of the DIMMs you are using).
• Typical Idle Current is generally the fix for Unraid freezes.  Locking up C-States fixes things too, but may be a bit heavy handed/overkill.
