16GB DDR4 ECC UDIMM for servers

This 16GB DDR4 2133MHz ECC unbuffered module is built for server and workstation systems that require error-correcting memory. It operates at a standard 1.2V with CL15 latency and a 2Rx8 rank configuration. The 288-pin DIMM form factor fits compatible DDR4 slots in enterprise platforms.

Capacity headroom at 16GB per module

A single 16GB stick provides substantial memory capacity for virtualisation, database workloads and multi-user applications. Systems with multiple DIMM slots can scale further by adding identical modules. The 2133MHz speed and PC4-17000 rating set the throughput ceiling for memory-intensive tasks on supported platforms.

Unbuffered ECC build with 288-pin layout

The module uses major-brand chips on an unbuffered DDR4 PCB with ECC circuitry for data integrity. Its 288-pin edge connector ensures a secure fit in standard DDR4 DIMM sockets without registration buffers. The 1.2V operation matches DDR4 specification voltage for stable, low-power performance in qualified systems.

Questions about this item

Will this DDR4 2133 ECC UDIMM work in a server that currently uses DDR4 modules?

This module uses the DDR4 standard at 2133 MHz with 1.2 V operation. It will only work in systems that support DDR4 memory; it cannot be used in platforms that require a different generation.

How can I verify the 16GB CL15 ECC module is running at the correct speed after installation?

Enter the system BIOS or use an OS utility such as CPU-Z to confirm the memory reports 2133 MHz, CL15 timings and ECC active.

Does the 288-pin UDIMM ship with any extra cables or brackets, or must I buy them separately?

The box contains only the single 16GB DDR4 2133 ECC UDIMM module; no cables, brackets or additional hardware are included.
