Hi,

Processor speed: 3GHz no overclocking.

I got a error message on ArchLinux  4.12.4-1-ARCH:

Aug 07 08:22:24 muon kernel: [Hardware Error]: Corrected error, no action required.

Aug 07 08:22:24 muon kernel: [Hardware Error]: CPU:8 (17:1:1) MC2_STATUS[Over|CE|MiscV|PCC|-|-|Poison|SyndV|-|CECC]: 0xdb30480b001f102c

Aug 07 08:22:24 muon kernel: [Hardware Error]: L2 Cache Extended Error Code: 31

Aug 07 08:22:24 muon kernel: [Hardware Error]: cache level: RESV, tx: RESV

 

My RAM is DDR4-3200 speed 2933, unable to get the actual timing without a unstable kernel.

I tested to increase the RAM speed to ~3000 and that's when the problem occurred.

I know there may be a problem with AMD ryzen, I don't know if it is related to the segfault problem : gcc segmentation faults on Ryzen / Linux

 

What 's the meaning of this code?

Is there anything to do?
