16GB DDR4 2133 ECC RDIMM Kit

This 16GB kit contains two 8GB DDR4 2133 MHz registered DIMMs with ECC and a CAS latency of 15. It is built for servers and workstations that require registered memory and cannot use standard desktop or laptop modules. The dual-channel configuration helps improve throughput on compatible platforms.

Upgrade from non-ECC or lower capacity

Replaces unbuffered or non-ECC memory in systems that mandate registered DIMMs for data integrity. The jump is worth it when your workload demands error correction and the motherboard specifies RDIMM support at this speed and rank configuration. It will not fit desktop or laptop boards that accept only unbuffered memory.

Straightforward DIMM installation

The 288-pin modules seat in standard DDR4 RDIMM slots at 1.2V. Follow the system manual for correct channel population and seating order to avoid boot failures. Mixing ranks or speeds, or installing in unsupported desktop boards, are the most common causes of detection issues.

Questions about this item

Does the 288-pin DDR4 RDIMM form factor fit my server motherboard?

These modules use the standard 288-pin DDR4 RDIMM layout required by compatible server and workstation boards.

What is the correct seating order for the dual-channel 2x8 GB kit?

Install one module in each memory channel according to the motherboard manual; the common mistake is populating both modules in the same channel.

When should the ECC registered DIMMs be replaced?

Replace modules only if memory diagnostics report uncorrectable ECC errors or the system logs persistent correctable error thresholds.
