Universal Micron MTA18ASF2G72PDZ-2G6E1 16GB DDR4-2666 ECC RDIMM accessory

SKU CH-1DK5-3D337

16GB DDR4-2666 ECC RDIMM memory module for server and workstation systems

  • 16 GB DDR4 memory for higher capacity
  • 2666 MT/s speed for faster data transfer
  • ECC RDIMM design for error correction
  • 72-bit width for wider data path
  • New condition ensures reliable performance

Enterprise Memory Module

This Micron 16GB DDR4-2666 ECC RDIMM is built for servers and workstations that require error-correcting memory. The registered design helps maintain signal integrity on heavily populated motherboards. It is not intended for consumer desktop or laptop platforms that lack ECC support.

Registered DIMM Construction

The module uses a 72-bit wide interface with a register chip between the DRAM and the memory controller. This buffering reduces electrical load, allowing larger memory configurations in multi-socket systems. Standard UDIMM slots in consumer hardware cannot accept this form factor.

ECC Upgrade Path

This part replaces non-ECC or unbuffered memory in qualified server platforms where data integrity is a priority. The upgrade is worthwhile when the motherboard and CPU explicitly support registered ECC modules. Systems without that validation will not boot with this memory installed.

Questions about this item

Does the DDR4-2666 interface limit the module to 2666 MT/s in practice?

Yes, the DDR4-2666 rating caps the data rate at 2666 MT/s when installed in a compatible server or workstation platform.

What physical slot and keying does the 288-pin RDIMM require?

It fits a standard 288-pin DDR4 RDIMM socket with the registered DIMM key notch; the 72-bit width includes ECC.

How is the module seated correctly, and what step is often missed?

Align the notch with the socket key, press firmly until both retention clips click, then verify the clips are fully locked.
