david11129 Posted July 19, 2019 Share Posted July 19, 2019 I recently upgraded my server from an E3-1285lv3 system to a dual E5-2680 systems with 128gb ram. The ram is new to the server and not carried over. The last couple days I got a warning for machine check errors, and then today I got a segfault warning from Plex. I'm suspecting a possible bad RAM stick, but surprisingly the BIOS doesn't have any ECC related logs. I am going to pull half the ram and try to narrow it down some. Does this sound like the right direction? I am attaching diagnostics for help. Thanks in advance! The problems start yesterday at approximately 1am. tower-diagnostics-20190719-0146.zip syslog.txt Link to comment

Any idea why the event wasn't BIOS detected? I pulled the First CPU's ram and replaced it with 4x8gb sticks. I have ECC errors with other ram sticks, and those were all reported in the BIOS event log. Also, Ths machine was my ESXI host for awhile. Is Esxi just not as in your face with system warnings? I consider this a good thing. Link to comment
