16GB DDR4 2666 Registered RDIMM

This 16GB DDR4 2666 registered module targets servers and workstations that require error-correcting memory with a registered buffer. The 2Rx8 organisation and PC4 21300 rating suit multi-socket platforms needing high capacity per DIMM slot.

288-pin DDR4 installation notes

Align the notch on the 288-pin edge connector with the motherboard key before applying even pressure until the retention clips engage. Registered DIMMs will not function in consumer boards that lack registered memory support, so verify platform compatibility first.

Sustained load behaviour

Registered buffering reduces electrical load on the memory controller during continuous throughput, helping maintain signal integrity at DDR4 2666 speeds. The dual-rank 2Rx8 layout allows the controller to interleave accesses, which steadies bandwidth during prolonged workloads.

Questions about this item

How can I confirm the 2666 MT/s speed and registered operation are active after installing the MTA18ASF2G72PDZ2G6J1?

Enter the server BIOS or UEFI and verify the memory frequency reads 2666 MT/s and the module type shows as registered RDIMM.

What ships with the MTA18ASF2G72PDZ2G6J1 and what must be sourced separately?

The box contains the 16 GB 288-pin DDR4 RDIMM only; any additional DIMMs, heat-spreaders or server rails are separate purchases.

Which capacity and rank version of this Micron DDR4 2666 RDIMM should I select for a dual-rank 16 GB requirement?

Choose the MTA18ASF2G72PDZ2G6J1 — it is the 16 GB 2Rx8 registered module matching that specification.
