942 memory training error

[VojtouNerCZ]

 Hello. I have z620 with e5 2665 and 64 gigs of HP ram. I wanted to install linux today (pc runs as plex server with arc GPU for transcode) but upon boot, I noticed memory training error. I am using those sticks for about year now, pretty sure error wasnt there after I installed them and because PC runs basically24/7, i didnt noticed this error when ocassionally PC freeze. I tried to find some info but I am not sure at what DIMM it is pointing me, because from what I found, others with this problem had exact DIMM slot pointed. I have only this. PC sometime randomly freeze with black screen and I have ti restart it, maxbe this is the issue. Can you help me? Thank you

Hi @VojtouNerCZ 

This error usually indicates that the memory modules are not placed correctly, or the processor is not placed correctly.

Try removing the memory modules and cleaning their contacts.

Thank you for reply. I was planning to repaste my CPU, so i dismantled all ram sticks and cpu, reseated, error is gone.
