Sounds like the root cause of the problem is how CPU voltage is adjusted with C-State. Manually setting CPU voltage to 1.22-1.25v may be another solution to your problem.

I think the system is running stable now.  I'm currently at 50 hours up time.  I think the key adjustment was to disable Global C-state control in the BIOS.  Here are some notes:
  • I have not yet installed the certified RAM.  Still using the CT2K16G4DFD8213
  • I tried different RAM configurations. For this 50 hour run, I had one stick in slot B2
  • I just booted with the recommended RAM configuration of A2 & B2 to see if it is stable with disabled c-state control
  • Upgrading to BIOS 3.00 did not fix the crashing
  • I found some threads on Reddit from Debian users with similar issues that reported success disabling global c-state control
  • I'm running mainline kernel 4.11.9-041109-generic.  Kernel 4.10 was just released to Ubuntu 16.04 with HWE activated.  I will try switching to that if things stay stable.

I'll report back on the c-state fix after more verification.

Thanks, ioio.  BIOS 3.00 does seem to help in the memory area, judging from the posts here.  I assume you continue to run your initial RAM.  Enjoy, John.

This morning I applied BIOS update 3.0 and reset UEIF to defaults.  The system has been stable under load for 6.5 hours.  I haven't seen it pass 10 hours without crashing so I'll have a better idea on the status tomorrow.

Good catch wardog.  Somehow I got the impression that it was ECC.  OPPS!  It looks like I need CT9993113 for ECC.  I'll try that if I can get the system stable on certified modules.  

This saved me some time in the near future when I would try to figure out why ECC tests fail.

This system is recording and syncing files non-stop so I would like the extra protection ECC provides.

Thanks!

A2 and B2 are stated in your manual and online on the MB's Specification tab as a table beside Memory.

Crucial says they are compatible, BUT they are not ECC sticks. Both Crucial and other sites confim  this.

Thanks for the update, ioio.  I did not realize your RAM was ECC.  Few here use it, I suspect.  You may be exploring almost virgin territory.  Hopefully you can get a refund on one or the other memories.  I'll keep an eye for updates.  Thanks and enjoy, John.

John,

Thank you for sharing your experience.  I just put some qualified RAM on order  (HX421C14FBK2/8).  I should have it to test on Tuesday.  On Monday I'll try other slot configurations as you suggest.  

I went with non-qualified RAM because it's ECC at a decent price.   The 2 qualified ECC modules are scarce and expensive.

I disabled SMT and OPcache because my research found there might be problems with them on Linux.  AMD is giving that instruction to some users in their support forums.  It's affecting programmers with specific workloads.  I don't think I'm affected by this issue but I tried turning them off regardless.  It is the case that I had to upgrade to an unsupported kernel for a stable system, I think that is a must for all Ubuntu LTS/Ryzen users.  This is due to Ryzen's SMT implementation.   I will reset back to defaults on Monday and continue testing.

I'll open a ticket with ASRock support.  

I'll post back if it gets resolved.  Thanks again for the help.

ioio, I cannot find your memory in the qualified list for Taichi.  What slots are you using (A2 & B2)?  Have you done a Load UEFI Defaults?  I am curious why you are running with SMT and OPcache disabled?  I had a similar problem (see signature for specs) and it turned out to be bad memory slots A1 and A2. A MB RMA solved the problem.  Have you opened a ticket with ASRock?  Please do, if not.  Can you beg, borrow or steal some memory on the qualified list?  For testing, try one stick in A1 and if it fails, try A2.  Continue until all slots are tested and if all fail, then try the other stick.  Good luck and enjoy, John.
