16GB DDR4-2133 ECC Registered Module

This 16GB DDR4 SDRAM module runs at 2133MHz with CL15 latency and 1.2V operation. It uses a 288-pin DIMM form factor and is built for server platforms that require registered, error-correcting memory.

Thermals Noise and Power

Standard JEDEC 1.2V voltage keeps power draw low for dense server configurations. Registered buffering reduces electrical load on the memory controller, helping maintain signal integrity under sustained workloads.

Upgrade Scope and Fit

Replaces non-ECC or unbuffered DIMMs in systems that mandate registered ECC memory with dual-rank x4 organisation. The jump is worth it when your platform requires data-integrity checking and registered signalling for stability.

Highlights

  • ECC protection prevents data corruption in critical workloads
  • Registered signal processing improves stability on multi-module server boards
  • Dual-rank organisation increases memory density per channel
  • 16 GB capacity supports larger datasets and virtual machines
  • 2133 MHz DDR4 speed delivers 17000 MB/s bandwidth

Questions about this item

How do I install this 288-Pin DDR4 DIMM and which notch alignment mistake should I avoid?

Align the single off-centre key notch on the 288-Pin DDR4 module with the slot ridge, press straight down until both side clips click, and ensure the registered ECC module is seated in a server board that supports registered memory.

What maintenance or replacement will this 16GB dual-rank ECC module need over its service life?

No scheduled maintenance is required; if a correctable error count rises or an uncorrectable error appears, replace the module — otherwise it runs for the server’s lifetime.

What thermal or voltage limit appears first when this 1.2V CL15 kit runs at 2133MHz under sustained load?

The JEDEC 1.2 V operating voltage is the first fixed limit; sustained heavy workloads keep the module at this voltage while the registered buffer manages signal integrity.
