Zonediver - Do you mean that I can check the sticks one at a time without any others and boot the system each time? The memory layout for the Supermicro board shows a minimum of 4 sticks (2 cpus 2 each). Will it boot safely or at all with only 1 stick? Thanks, Richard

Squid - Thanks for your help. I did realize that it was a memory stick problem as noted in my reply to civic95man. The system froze twice running the parity build with 8 memory sticks. Then I tried running the parity build with 4 sticks "twice". The system froze the 1st time and then ran successfully the 2nd time in 15+ hours with the other 4 sticks - no error messages. I am now trying to find any bad ones using them one at a time with 3 "good" sticks. Very time consuming process! I am trying this while copying files to the array from my other system with Beyond Compare. Problem is that the memory usage is very small. Is there a faster and better way to find out which sticks are bad? Thanks again, Richard

Thanks, I will check if the bios is up to date. Also I tried running with 32gb instead of 64gb - the 1st run crashed after 4 hours into my parity build - the second run seems okay using the other 32gb completed my parity build in 15 hours and ran for another 8 before I shut it down. The 2nd 32gb appear to be okay - I added 2 sticks back (now 48gb) and testing while loading files to the array - hopefully I can find out if there are any bad memory sticks. Thanks again

Hello: I have been a member since March 2018 but have never had any problems with Unraid or my first server. Technically I am a newbie in the Linux world although I have worked with Windows for many years. I just started my setting up my 2nd Unraid server Supermicro which is similar to my 1st server. Unraid - Version 6.8.3 Motherboard - Supermicro X9DRi-LN4+/X9DR3-LN4+, Version REV: 1.10 - BIOS AMD Version 3.3 Processor - Intel Xeon CPU E5-2690 0 @ 2.90 GHz Memory - 64GB DDR3 Multi-bit ECC So far I have installed 13 Hard drives - 2 Parity, 1 Cache and 10 Data. The drives do not contain any data since they were formatted last night. The system was so "noisy" that I cut the power off. I started it today to perform the Parity-Sync/Data-Rebuild and discovered the Machine Check problem. I have attached the Diagnostics and Syslog zip files. I do not know how to run the mcelog program noted in the error message. Please help! Thank you, Richard server16-diagnostics-20200805-0914.zip server16-syslog-20200805-1913.zip
