16GB DDR4 ECC RDIMM Server Module

This 16GB DDR4 2666MHz ECC registered DIMM uses a 2Rx8 organisation and runs at 1.20V with CL19 latency. It is built with major-brand chips and serves as a direct replacement for Micron MTA18ASF2G72PDZ-2G6 and related part numbers. The 288-pin module targets server and workstation platforms that require registered ECC memory.

Suits ECC registered platforms only

The module fits systems that accept DDR4 2666MHz registered ECC RDIMMs in a 2Rx8 configuration. Builders using consumer desktop boards, unbuffered DIMM slots, or non-ECC memory controllers should look elsewhere because the registered buffer and ECC function will not be supported.

16GB capacity for multi-module arrays

A single 16GB stick provides a practical building block for populating multiple channels in dual-socket servers. Capacity scales with the number of populated slots, while headroom ends when all supported DIMM sockets are filled or the platform's maximum memory limit is reached.

Questions about this item

What motherboard slot and DDR generation does this 288-pin DDR4 RDIMM require?

It fits a standard 288-pin DDR4 DIMM slot that supports registered ECC memory at 1.2 V.

Can I mix this CL19 2666 MHz module with slower DDR4 ECC RDIMMs already in my server?

Yes, the system will run all modules at the lowest common speed and latency.

How do I confirm the module is recognised at 2666 MHz with ECC active after installation?

Check the BIOS memory info or run a tool such as dmidecode to verify speed, rank and ECC status.
