16 GB DDR4 ECC Registered Module

This 16 GB DDR4 DIMM delivers 2666 MHz speed with CL19 latency and 1.20 V operation. It adds error-correcting code and registered signal processing for data integrity. The 288-pin form factor fits standard desktop memory slots. It suits workstations and servers that require ECC stability.

Fits Standard 288-Pin DIMM Slots

The module installs in any desktop board accepting DDR4-2666 registered DIMMs. Registered buffering reduces electrical load on the memory controller. ECC capability corrects single-bit errors without system interruption. RoHS and China RoHS certifications confirm environmentally compliant manufacture.

Upgrades Non-ECC or Lower-Capacity Kits

Replacing non-ECC memory with this module adds hardware error correction for critical workloads. Swapping smaller DIMMs for 16 GB increases total capacity in registered-channel configurations. The jump is worth it when data integrity and higher density outweigh the cost of registered ECC memory.

Questions about this item

Will the CL19 latency become a bottleneck under sustained heavy workloads?

CL19 is the rated CAS latency at 2666 MHz; it remains constant during sustained use and does not change under load.

How much heat and power does the module draw when running continuously at 2666 MHz?

The module operates at 1.20 V; DDR4 registered DIMMs at this voltage typically run cool and draw low power under continuous operation.

Does my motherboard need to support registered ECC DDR4 DIMMs for this module to function?

Yes, the module is a 288-pin registered ECC DDR4 DIMM and requires a motherboard with registered ECC DDR4 support.
