Post by: cgone on February 03, 2020, 09:03:03 pm
I now get twenty until thirty messages per day of the following message in the logfile:

With the command "mcelog --k8 --ascii" the event decodes to

CPU 0 4 northbridge
MISC c01a0ffe01000000 ADDR 9224b940
  Northbridge RAM Chipkill ECC error
  Chipkill ECC syndrome = a612
       bit46 = corrected ecc error
       bit59 = misc error valid
       bit62 = error overflow (multiple errors)
  bus error 'local node response, request didn't time out
             generic read mem transaction
             memory access, level generic'
STATUS dc094000a6080a13 MCGSTATUS 0
MCGCAP 106 APICID 0 SOCKETID 0

On the apu2 I use the newest BIOS v4.11.0.3.
I experience no crash and no failing of any service at this device.

Does the event mean that the whole device will fail soon by memory and should I replace the device as fast as possible?

Many thanks. A very good idea.
I mailed to support@pcengines.ch. If I get a proper answer, I will put it in the forum, too.
