Server DDR5 RDIMM for ECC workloads

This 16 GB registered module delivers DDR5 5600 speed with CL46 latency and on-die ECC for data integrity. It targets servers and workstations that require error correction and registered signal processing. The single-rank design keeps electrical loading low on populated channels. Buyers needing non-ECC consumer memory should look elsewhere.

Fits 288-pin DDR5 RDIMM slots on qualified server

The module operates at 1.10 V standard voltage and requires a platform that supports registered DDR5 with ECC. No heat spreader is included, so airflow across the DIMM area must be provided by the chassis. It frees the memory controller from parity overhead by handling correction on the module. Systems without registered DDR5 support cannot use this module.

Runs at standard JEDEC voltage with no spreader

At 1.10 V the module draws minimal power and relies on case airflow for cooling. Registered buffering adds negligible latency while stabilising heavy loads across multiple slots. Single-rank organisation helps maintain signal integrity at 5600 MHz. Builds with restricted DIMM clearance or passive cooling should verify spacing before installation.

Questions about this item

What limits sustained throughput when this CL46 DDR5-5600 module runs continuously?

The CL46 latency at 5600 MHz sets the timing boundary for sustained data rates.

How much heat does this 1.10 V registered DIMM produce during all-day server workloads?

At 1.10 V with no heat spreader, the module relies on chassis airflow to stay cool.

Which server motherboard slot accepts this 288-pin registered DDR5 module?

A DDR5 RDIMM slot supporting registered ECC memory is required.
