Server memory upgrade

This OWC module is a 32GB DDR4 ECC Load Reduced DIMM designed for servers, workstations and NAS systems. It operates at 2666MHz with a CL19 latency and runs at 1.2V. The 288-pin form factor fits compatible server platforms that support LRDIMM technology.

Capacity and headroom

The single 32GB stick provides substantial memory density for virtualisation, large datasets or multi-user workloads. The 4Rx4 organisation and Load Reduced design reduce electrical load on the memory controller, allowing higher total capacity per channel. Backward compatibility with 2133MHz and 2400MHz systems offers flexibility when populating mixed-speed slots.

Build integration

This module requires a platform that explicitly supports DDR4 ECC LRDIMM memory; it will not work in standard desktop computers or alongside unbuffered DIMMs. JEDEC and RoHS compliance ensures a warranty-safe upgrade for OEM-qualified systems. The lack of a heat spreader keeps the profile low for dense server chassis.

Perguntas sobre este artigo

Will the 2666MHz CL19 4Rx4 ECC LRDIMM run with the 2133MHz and 2400MHz modules already in my server?

Yes, the module is backward compatible with 2133MHz and 2400MHz speeds, but it must not be mixed with unbuffered memory.

How can I confirm the 32GB LRDIMM is operating correctly after installation?

The server BIOS should report 32GB at 2666MHz with ECC active, and the operating system will show the full capacity without errors.

Does the single 32GB 288-pin LRDIMM ship with a heat spreader or any extra accessories?

The module has no heat spreader and the box contains only the memory stick itself; no cables or brackets are included.
