elnevera Posted July 7, 2020 Share Posted July 7, 2020 Hi All, My Unraid server (6.8.2) was running just fine when we had a couple of powercuts a few days ago. I had been meaning to look into a UPS but never got around to it.... Anyway, I powered the system back up and let it do the usual parity check. All okay, but since then the server has repeatadly locked up/crashed. I have attached the diagnostics I grabbed between lock ups. What ever the problem is, it appears to be getting worse as the time between lock ups is decreasing. I am currently running memtest. I have tried running without Dockers and it still locked up. Can anyone help me with the next steps should the memtest pass okay? Server is running on Ryzen 5 1600 and 32gb memory. Cheers. mystique-diagnostics-20200707-1835.zip Quote Link to comment

Overclocked RAM is a know issue with Ryzen, see here, also check the power supply idle control setting, even if before you were overclocking you should stop. Quote Link to comment

Thanks for replying. I will check the bios whem Memtest has finished but I don't think I have any overclocks (CPU or Memory) in place. Quote Link to comment
ChatNoir Posted July 7, 2020 Share Posted July 7, 2020 XMP is considered overclocking the standard DDR4 speed (2133MHz). If you are using it, try disable it. Quote Link to comment

I have set it to default and also changed the power supply idle setting. I have also attached another diagnostic and it hasn't locked up since coming back on. I am still confused as to why after the power cut it became unstable with no changes to the bios...... Also, can anyone recommend a UPS that will allow a clean shut down in the event of another power cut? mystique-diagnostics-20200707-2128.zip Edited July 8, 2020 by elnevera Forgot to add the diagnostic Quote Link to comment
elnevera Posted July 9, 2020 Author Share Posted July 9, 2020 35 hours and no lock up. Still none the wiser as to why a power cut changed anything. 1 Quote Link to comment

The cut could have followed a surge and a tiny surge could cause tiny damage that is not normally perceivable, unless you are overclocking which narrows your margin. Basically anything is possible when electricity can't be trusted. Quote Link to comment
