Hi,

 

I have found machine check events on my server. Fix common problems has warned me for three times now so I guess it's time to find out what the problem is. Can someone help to solve the issue? I have my thoughts what the issue is. I have attached my diagnostic file to this post.

I see this in the syslog:

Are this memory error's? I've checked my bios but I can't find anything related to this..

Are this memory error's?

Yes, at least that's what it looks like.

 

 

Thank you for the reply.

 

The weirdest part is I don't see errors in my bios log files. Any idea how to diagnostic this further?

Investigating!

 

I have found the memtest86 what you see in the options during booting of unRAID. It's running at the moment. I'll keep you informed.

memtest86 won't detect ECC errors, passmark memtest might in some cases.

So this is ecc error? Googling Passmark memtest.

Looks like a corrected error, board's system event log might also have some more info.

Appreciate your guidance.

 

I've checked the event log via IPMI and there are no events. The latest event was on 2019-5-2.

 

I have put Passmark memtest on usb stick and it is now running.

If no errors on memtest best bet is to remove one or more dimms at a time and see if the log errors go away.

Okay. 

 

The log of unRAID is reporting Chan#1_DIMM#0. I'm guessing this is DIMM A2? So the first DIMM position (A) on the motherboard then the second slot of DIMM A thus DIMM A2? I'm guessing there is also a channel 0. So channel 0 --> slot 1, channel 1 --> slot 2.

The Passmark memtest detected ECC error's. I'm trying to figure out which module is defect..
