Micron 16GB DDR4-2666 ECC unbuffered memory module, part number MTA18ADF2G72AZ-2G6E1ZG. Tested and working.
This is a 288-pin ECC unbuffered DIMM (ECC UDIMM) rated for DDR4-2666 (PC4-21300) at 1.2V, dual-rank 2Rx8. Error-correcting memory detects and fixes single-bit errors automatically, which is why it's used in servers, NAS units, workstations, and homelab machines running ZFS or virtualization. It's a good fit for compatible server boards, Xeon E-series and entry server platforms, and Ryzen systems on boards that support ECC UDIMMs.
What's included: 1x Micron 16GB DDR4-2666 ECC UDIMM.
Condition: May show cosmetic signs of wear that do not impact functionality. The picture is an example of one stick out of the lot that is being sold, the actual item may visually differ from the item pictured but part number and compatibility will be match the description.
Please check compatibility before buying:
This is ECC unbuffered (UDIMM) memory. It is not registered or load-reduced memory (RDIMM/LRDIMM), and the two are not interchangeable. Many server boards require RDIMMs and will not post with this module.
Most consumer desktop motherboards and CPUs do not support ECC memory. Some will run it with ECC disabled, and others won't post at all. Check your motherboard's qualified vendor list first.
This is DDR4. It will not fit DDR3 or DDR5 boards, or laptops.
