In the last couple of weeks my 11.0-U4, 32GB, FreeNAS Mini (mainboard replaced a few months ago under warranty by iXsystems after failing) has reported 4 instances of memory error:
The last two were yesterday and today - in between them I reseated the 4 memory modules, generally checked the inside of the box, and mentally prepared for the next phase if there was a repeat event. So, here we are.
Dmidecode results today:
The ASRock manual doesn't have a memory map and my searching so far has not turned one up, so I'm not encouraged that the information above is very helpful (if at all) in physically locating the problem - assuming it is with a memory module, in which of the four slots it resides? A general Google search didn't give me much hope either. I'd be delighted if anyone can tell me how I can use that information or anything else that we can get from a functional (if flakey) FreeNAS install to nail down the ailing component(s).
I'm gearing myself up to pull the four drives and install them in spare bays in my Dell backup box - more on that in my other post in Storage - then run Memtest86+ on the box to see if I can find a bad module. I'm uncertain right now about the testing protocol - if I do all four simultaneously will Memtest allow me to identify a culprit or must I test each one alone? If anyone has any pointers on that topic I'd be delighted to have them (I only ever tested "good" memory before - no errors found).
In fact, any comments will be welcome - this is new territory for me.

The ASRock manual doesn't have a memory map and my searching so far has not turned one up, so I'm not encouraged that the information above is very helpful (if at all) in physically locating the problem - assuming it is with a memory module, in which of the four slots it resides? A general Google search didn't give me much hope either. I'd be delighted if anyone can tell me how I can use that information or anything else that we can get from a functional (if flakey) FreeNAS install to nail down the ailing component(s).
I'm gearing myself up to pull the four drives and install them in spare bays in my Dell backup box - more on that in my other post in Storage - then run Memtest86+ on the box to see if I can find a bad module. I'm uncertain right now about the testing protocol - if I do all four simultaneously will Memtest allow me to identify a culprit or must I test each one alone? If anyone has any pointers on that topic I'd be delighted to have them (I only ever tested "good" memory before - no errors found).
In fact, any comments will be welcome - this is new territory for me.
