Hi folks,
My FreeNAS server has been throwing MCA errors that seem to be related to ECC memory. I've ordered a replacement DIMM, but I'm wondering if its possible to identify exactly which module I need to replace. My server is an ASRock C2550D4I w/ 16 gigs ECC memory and 2x5 TB & 2x3 TB WD Red NAS hard drives.
The recent errors are here. An example is:
Running dmidecode gives this data. What I believe is the relevant part is here:
So a few questions:
1) Is it likely that replacing a single DIMM will solve this problem, or can it be determined from these logs that the problem lies with the motherboard?
2) If it is indeed a single DIMM, which one should I swap out? Or do I need to just guess and check?
Thank you for any help!
