Machine Check Events - Help needed understanding the issue

Recommended Posts

Posted (edited)

So, I'm in the process of setting up my unRAID server when I got a notification regarding Machine Check Events.


I've attached the diagnostics. The relevant part of the syslog appears to be:


Jun  4 22:53:27 TheRamsServer kernel: mce: [Hardware Error]: Machine check events logged
Jun  4 22:53:27 TheRamsServer kernel: [Hardware Error]: Corrected error, no action required.
Jun  4 22:53:27 TheRamsServer kernel: [Hardware Error]: CPU:0 (17:71:0) MC27_STATUS[-|CE|MiscV|-|-|-|SyndV|-|-|-]: 0x982000000002080b
Jun  4 22:53:27 TheRamsServer kernel: [Hardware Error]: IPID: 0x0001002e00000500, Syndrome: 0x000000005a020005
Jun  4 22:53:27 TheRamsServer kernel: [Hardware Error]: Power, Interrupts, etc. Ext. Error Code: 2, Link Error.
Jun  4 22:53:27 TheRamsServer kernel: [Hardware Error]: cache level: L3/GEN, mem/io: IO, mem-tx: GEN, part-proc: SRC (no timeout)


Can anyone please help me to understand this output? My server's component details are in my signature.

For anyone stumbling across this post having the same issue, this problem *appears* to have been solved by simply updating my BIOS.


From some cursory Googling, the problem appeared to be related to overclocking my memory (to be clear, I was only running it at the XMP-rated 3600MHz speed). I had already run a memTest on the memory sticks which brought up no errors.


So, I simply updated my BIOS to see if that would solve the problem. I haven't had any Machine Check Events warnings since.
