March 30, 20242 yr I recently got a random MCE event (not related to boot) and am looking for help determining why. I've attached Diagnostics and syslog. Mar 17 00:47:35 Glacier kernel: mce: [Hardware Error]: Machine check events logged Mar 17 00:47:35 Glacier kernel: [Hardware Error]: Deferred error, no action required. Mar 17 00:47:35 Glacier kernel: [Hardware Error]: CPU:1 (19:21:2) MC15_STATUS[-|-|-|-|-|-|UECC|Deferred|-|-]: 0x80057419fa800257 Mar 17 00:47:35 Glacier kernel: [Hardware Error]: IPID: 0x0000000000000000 Mar 17 00:47:35 Glacier kernel: [Hardware Error]: Bank 15 is reserved. Mar 17 00:47:35 Glacier kernel: [Hardware Error]: cache level: L3/GEN, tx: DATA This is a pretty new build and has been running without issue so far. There is no overclocking on anything, I do have ECO mode enabled in BIOS and Power Save CPU scaling set through Tips & Tweaks - 5900X, MSI PRO B500-VC, 128GB Patriot Viper RAM @2666Mhz: https://pcpartpicker.com/user/Fablemaster/saved/3vq4NG glacier-syslog-20240319-1904.zip glacier-diagnostics-20240319-1929.zip
March 30, 20242 yr Author Any thoughts on specifics, or any clues as to how to try and address it? (Hardware, power related, cosmic rays, etc?) Does the error being deferred have any important relevance vs being undeferred? Right now my initial plan is to wait and see if it happens again. If so I'll probably try disabling ECO mode in BIOS, unless anyone has anything more helpful or directed to try and move forward with.
