Dimm Error Identification

[statecowboy]

Hi guys.  I was curious how to rectify the unraid mem errors with my actual dimms.  In my case, I am able to log in to my web console and see errors.  I also have an LED that blinks when an error is registered.  In this case DIMM H2 is lit up and my web console output the following:

 

1679 02/17/2018 23:29:30 Mmry ECC Sensor Memory Correctable ECC. CPU: 2, DIMM: H2. - Asserted

 

That said, this is the error I get in unraid.

Can someone explain how to tell from the unraid log which DIMM I am getting an error on?  Obviously I can check my web console, but I was curious what the methodology is.

 

Thanks

Hi guys.  I have another error in my memory which I've added below to explain my question above (I've also attached my last diagnostics).

From unRAID logs:

The methodology is to check the board's SEL, you'll likely won't be able to decipher the problem DIMM from the unRAID logs.
