January 9, 20206 yr First of all, my disclaimer - I do not have much experience, having built UnRAID 6.8.0 system from scratch. The system goes systematically down (neither Web UI is responding, not docker containers and smb shares) and only hard reset helps. All the components are brand new. The configuration is as follows: Fractal Design Node 804 - Corsair Rm850x, AMD Ryzen 3600, Noctua NH-D15s, 64Gb DDR4 3200Mhz Corsair Vengeance LPX RAM, AsRock X570m Pro, Zotac RTX 2070 Mini, 2x1Tb Samsung 970 Evo NVMe Cache, 2x2tb Raid 1 SSD as Unassigned devices, 10 HDDs with 2 Parities. Initially I thought that I messed with plugins installation and some configs. Yesterday I reinstalled everything from scratch only keeping original network and array configuration files. Today the server is unreachable again. I attach the lates diagnostics files I have. Will also try to get the latest file from today once I reach the server that is currently stuck and cannot be reached remotely again. Any advice and help is appreciated. kk-server-diagnostics-20200107-2015.zip kk-server-diagnostics-20200107-1730.zip Edited November 1, 20205 yr by andrey_kk
January 9, 20206 yr Community Expert Though 3rd gen Ryzen should have this fixed there have been some reports it can still be a problem, so worth trying: Ryzen on Linux can lock up due to issues with c-states, make sure bios is up to date, then look for "Power Supply Idle Control" (or similar) and set it to "typical current idle" (or similar), or completely disable C-sates.

I use latest ASRock BIOS version 2.3
January 9, 20206 yr Author Update: after 5 hours of uptime it is down again but differently. SMB works, WebUI is reachable but Diagnostics report cannot be generated, starts but never ends. None of the Docker containers are openable and Docket itself. Docker in settings cannot be opened either. Reboot does not work, nor from Web UI, nor from console. Only hard reset helps. What else can I look for?

It did not boot properly. Second hard reset helped. I also put "Global C-state..." option to enabled besides current already set to "typical". Will monitor.

January 10, 20206 yr Author Update after night uptime- the same problem. Current is set to typical, global C-State disabled. Web UI login works but all the rest is stuck as before. Here is syslog file. And also diagnostics report at the beginning after last hard reset when the server was working properly. syslog kk-server-diagnostics-20200109-2038.zip
January 10, 20206 yr Community Expert There are multiple general protection errors, start by running memtest, also make sure RAM isn't overclocked, make sure you're respecting max support speed depending on system config:

Will do tonight. RAM is 4x16gb DDR4-3200 in stock XMP Profile. Will do memtest and try to find the ranking. Assume I definitely need to go down to 2993 or 2667 MHz. Will report accordingly.
January 11, 20206 yr Author Updated: report as promised- switched to Auto setting for memory, it turned to 2133 MHz. Since then now 14 hours uptime without any issues. Will monitor and report later again. Maybe will try to increase memory frequency a bit later within the allowed limits. For some reason cannot run memtest86. At boot I choose it, nothing happens, system reboots and again to the same normal boot status. Thanks a lot for instructions and advice! Great support!

January 12, 20206 yr Author Update: after 2 days and 4 hours of uptime, everything seems to be stable. Please consider to be solved. Thanks a lot for help and instructions!
January 12, 20206 yr For info I have ryzen 3900x with same memory sticks and had to bring them down to 3000 for stability.

Is it at 1,35V or 1,2V? I have my main PC with 3900x and Kingston HyperX memory (is quite expensive though) that is 3600 MHz stock XMP profile but I run it 3800 with Infinity Fabric overclocked to 1900 MHz and all is stable.
January 13, 20206 yr Sorry oversimplified response. I meant 3200mhz. this is what i have: https://www.memorybenchmark.net/ram.php?ram=G+Skill+Intl+F4-3200C16-16GTZR+16GB&id=12243 each 16GB; I have 64Gb total. They are 1.2V

I have Corsair LPX. They are 1.2V at stock profile but go to 1,35V in XMP at 3200 MHz. Yours seem to be GSkill, they may be different. Edited January 13, 20206 yr by andrey_kk
January 16, 20206 yr Author Update: turned memory to 2993 MHz, system is not stable. Decreased to 2667 MHz- now stable for 3 days. Leave for now at this setup.
