Green rectangular DDR4 LRDIMM module with black chips and gold contacts

Micron Technology, Inc.

Micron Technology, Inc. MTA18ASF2G72PDZ-2G6E1 16GB DDR4 2666 4DRx4 server RAM

SKU CH-TSEY-TCDAH

16 GB DDR4 LRDIMM server memory with ECC and registered buffering at 2666 MT/s

  • ECC protection prevents data corruption in critical workloads
  • Registered buffering improves signal integrity for dense configurations
  • LRDIMM architecture reduces electrical load on the memory bus
  • 2666 MT/s transfer rate delivers responsive server performance
  • 16 GB capacity supports memory-intensive virtualisation and databases

Server LRDIMM for registered memory slots

This Micron LRDIMM module delivers 16 GB of DDR4 capacity for servers that require registered, error-correcting memory. The load-reduced design supports higher densities per channel than standard RDIMMs. It is intended for administrators upgrading or populating compatible enterprise platforms.

Verify registered ECC support and rank limits

Confirm the motherboard accepts registered DDR4 with ECC and can address 4DRx4 (8Rx4) modules at 2666 MT/s. Check the platform's qualified vendor list for this part number and ensure the CPU memory controller supports the total rank count planned. Mixing registered and unbuffered DIMMs is not supported.

288-pin LRDIMM build for dense configurations

The 288-pin form factor fits standard DDR4 server slots while the load-reduced architecture reduces electrical load on the memory bus. Registered signalling and on-die ECC help maintain data integrity in multi-DIMM-per-channel layouts. Gold-edge contacts resist oxidation during long-term deployment.

Questions about this item

Does the MTA18ASF2G72PDZ-2G6E1 ship as a single 16GB LRDIMM or do I need to order multiple modules?

The module is a single 16GB LRDIMM with a 288-pin DDR4 interface; each unit provides the full 16GB capacity.

Should I choose the 4DRx4 (8Rx4) rank version or look for a different rank configuration?

This part is built as 4DRx4 (8Rx4); select it when your server platform requires that specific rank organisation for maximum density.

What does the PC4-2666V rating mean for actual throughput in a DDR4-2666 server?

PC4-2666V indicates a peak transfer rate of 2666 MT/s, delivering the standard DDR4-2666 bandwidth when installed in a compatible registered-ECC slot.
