16 GB DDR4 ECC Registered DIMM

This 16 GB module is built for servers and workstations that require DDR4 2666 ECC registered memory. It uses a dual-rank x4 organisation and major-brand chips to deliver error-correcting stability for critical workloads.

Verify DDR4 RDIMM support and 288-pin compatibility

Your system must accept DDR4 registered DIMMs at 2666 MT/s and provide 288-pin slots. Desktop and laptop platforms cannot use this module. Consult the motherboard or server manual for supported capacities, population rules and voltage requirements before ordering.

Lifetime warranty and US-based technical support

The bundled lifetime warranty covers the module for as long as you own it. Complimentary United States based technical support is available before, during and after purchase to assist with installation, compatibility checks and troubleshooting.

Questions about this item

Does the 16GB DDR4 2666 ECC RDIMM ship as a single stick or a kit, and are any brackets or cables needed?

The module is a single 16GB stick in a 288-pin DIMM form factor; no brackets, cables or extra parts are required for installation.

I see 2Rx4 and PC4-21300 on the label — which version should I pick for a dual-channel server board?

Choose the 2Rx4 dual-rank module; its PC4-21300 rating matches DDR4 2666 speed and works in dual-channel configurations when populated per the motherboard manual.

What does the 2666 MHz rating actually deliver once the RDIMM is seated in a registered-memory server?

The module runs at 2666 MT/s with 1.2V standard DDR4 voltage, providing ECC error correction and registered buffering for stable server workloads.
