Server ECC RDIMM 16GB 2666MHz

This registered DDR4 module delivers 16GB of error-correcting memory for Micron-compatible servers and workstations. The 2666MHz speed and CL19 latency suit stable, continuous operation in enterprise environments. ECC and registered buffering protect data integrity under heavy workloads. It targets IT professionals who need reliable capacity expansion for supported platforms.

Installation notes for registered DIMMs

The 288-pin RDIMM seats in standard DDR4 server slots at 1.2V without extra configuration. Registered buffering adds electrical load, so the motherboard must support RDIMM populations and matching rank limits. Mixing registered and unbuffered modules prevents boot. Always verify the system qualified-vendor list before installing.

Capacity headroom and limits

A single 16GB 1Rx4 rank leaves additional slots open for further expansion within the platform's maximum. The module handles typical virtualisation, database and file-serving workloads that fit within its capacity. Applications requiring larger per-socket memory footprints or higher frequencies will exceed what this part provides.

Questions about this item

How can I verify the module is running at DDR4 2666 with CL19 after installation?

Enter the system BIOS or use a tool such as CPU-Z to confirm the memory speed shows 2666 MT/s and the CAS latency reads 19.

What is included in the package and do I need any extra parts?

The box contains one 16 GB 288-pin DDR4 ECC RDIMM; no additional components are required for installation.

Which capacity and rank should I choose for a Micron-compatible server?

This 16 GB 1Rx4 registered module matches the Micron MTA18ADF2G72PZ-2G6 specification for direct compatibility.
