16GB DDR4 2133 ECC RDIMM

This 16GB DDR4 2133MHz ECC registered DIMM targets server and workstation operators who need reliable memory for multi-threaded workloads. It uses a Samsung chipset and runs at the standard 1.2V DDR4 voltage. The module is a direct replacement for Samsung M393A2G40DB0-CPB0Q and M393A2G40DB0-CPB3Q part numbers.

Capacity and headroom

A single 16GB rank provides enough room for virtualisation hosts, database buffers and large dataset processing on supported platforms. The CL15 latency and 2133MHz speed deliver steady throughput for typical enterprise applications. Systems requiring higher memory density per slot or faster clock rates will exceed what this module can supply.

Upgrade context

This module replaces failed or smaller Samsung DDR4 RDIMMs in qualified servers and workstations. The jump is worthwhile when expanding total system memory within the 2133MHz registered ECC requirement. It is not suited for consumer desktop boards that accept only unbuffered non-ECC memory or for platforms limited to lower DDR4 speeds.

Preguntas sobre este artículo

Will this 2Rx4 ECC RDIMM run at 2133 MHz if I mix it with existing 1Rx8 DDR4 modules in the same server?

The module is rated at DDR4 2133 (PC4-17000) with CL15 timing and 1.20 V; mixing ranks is supported by the memory controller, so the system will negotiate the highest common speed and latency across all populated slots.

How can I verify the module is operating as ECC registered memory after installation?

Check the BIOS or OS memory report — it should show 16 GB at 2133 MHz, ECC enabled, registered DIMM, 2Rx4 organisation and 1.2 V.

Does the package include only the single 288-pin DIMM or are there extra parts such as a heat spreader or installation tool?

The box contains one 16 GB DDR4 2133 MHz ECC RDIMM (288-pin) and nothing else; no heat spreader, no tools, no additional cables are included.
