SKU CH-49NH-WP0M4

A 32 GB DDR4-2666 ECC registered DIMM with CL19 latency and 288-pin form factor

  • 32 GB capacity handles large workloads
  • DDR4-2666 speed delivers 21300 MT/s bandwidth
  • ECC registered design protects data integrity
  • CL19 latency supports responsive operation
  • 288-pin DIMM fits standard desktop slots

32 GB ECC Registered DIMM

The Axiom 32 GB DDR4-2666 module is a single 32 GB registered DIMM built for systems that require error-correcting memory. It targets workstations and servers where data integrity matters more than low latency. Buyers who need non-ECC unbuffered memory for consumer boards should look elsewhere.

CL19 288-pin registered layout

The stick uses a 288-pin DIMM form factor with registered signalling and CL19 timing at the DDR4-2666 data rate. Registered buffering reduces electrical load on the memory controller, allowing higher capacities per channel. Systems without registered-memory support in the chipset or BIOS will not post with this module installed.

PC4-21300 upgrade path

This module replaces lower-capacity DDR4 ECC RDIMMs or fills empty slots on platforms qualified for PC4-21300 speeds. The jump is worthwhile when the workload hits the current memory ceiling and the platform accepts registered ECC at this speed. First listed by the manufacturer in June 2025, it suits fresh deployments or capacity expansions on compatible hardware.

Questions about this item

What speed does the DDR4-2666 interface actually run at?

The module is rated at DDR4-2666 (PC4-21300), so it operates at 2666 MT/s when the platform supports that data rate.

Will this 288-pin DIMM fit my motherboard slots?

It uses the standard 288-pin DDR4 DIMM form factor, so it fits any desktop board with DDR4 DIMM slots.

How do I install this ECC registered DIMM correctly?

Align the notch with the slot key, press down firmly until both retention clips click, and ensure the platform supports ECC registered memory.
