16GB DDR4 ECC RDIMM for servers

This 16GB DDR4 2133MHz registered DIMM delivers error-correcting code memory for server and workstation platforms. It operates at 1.2V with a CL15 latency and uses a 2Rx4 organisation. The module is built with major-brand chips and carries a lifetime warranty from A-Tech.

Verify DDR4 RDIMM support and 2133MHz compatibility

Confirm that your system accepts DDR4 registered ECC modules in a 288-pin DIMM slot before ordering. Check the motherboard or server documentation for supported speeds, maximum capacity per slot and registered DIMM requirements. The module replaces Samsung M392A2G40DM0-CPB, M393A2G40BB0-CQB, M393A2G40DB0-CPB and M393A2G40EB1-CPB part numbers.

Fits single-slot upgrades in registered memory

The single 16GB module occupies one 288-pin slot and provides registered buffering for signal integrity in multi-DIMM configurations. It frees remaining slots for additional capacity while maintaining ECC protection. Systems requiring unbuffered UDIMMs or non-ECC memory cannot use this module.

Questions about this item

Does the 16GB DDR4 2133MHz ECC RDIMM ship as a single 288-pin module or must I buy additional sticks?

The product is a single 16GB module (1 x 16GB) with a 288-pin DDR4 DIMM form factor, so nothing else is required to add 16GB of registered ECC memory.

Should I choose this 2Rx4 CL15 1.2V version or look for a different rank or latency?

This module uses a 2Rx4 organisation, CL15 latency and standard 1.2V DDR4 voltage; select it when your server or workstation qualification list calls for those exact specifications.

What does the 2133MHz PC4-17000 rating mean once the RDIMM is installed in a live system?

The memory will run at up to 2133 MT/s (PC4-17000 bandwidth) with ECC error correction and registered signalling, provided the platform supports DDR4-2133 registered DIMMs.
