OWC 32GB DDR4 ECC RDIMM

This 32GB DDR4 2666MHz ECC Registered RDIMM is built for servers, workstations and NAS systems that require registered memory with error correction. It operates at 1.2V with a CL19 latency and a 2Rx4 rank configuration. The module is not compatible with standard desktop computers and cannot be mixed with unbuffered memory.

288-pin DDR4 registered module

The 288-pin RDIMM fits DDR4 slots that support registered ECC memory and is backward compatible with 2133MHz and 2400MHz bus speeds. It requires a platform that accepts registered DIMMs and will not work in consumer boards limited to unbuffered modules. Using this module frees the system from single-bit errors and allows higher capacity configurations per channel.

Sustained operation at 2666MHz

Under continuous load the module maintains its rated 2666MHz speed and 1.2V voltage without a heat spreader, relying on chassis airflow for cooling. ECC and registered buffering provide data integrity during extended compute or storage workloads. The JEDEC-compliant design ensures stable timing over long periods rather than short benchmark bursts.

Perguntas sobre este artigo

What is the CAS latency of this DDR4 2666MHz module?

The module runs at CL19 latency, which is the standard timing for JEDEC DDR4 2666 registered DIMMs.

Does this module include a heat spreader for all-day operation?

No heat spreader is fitted; the registered design and 1.2V voltage keep thermals within spec for continuous server workloads.

What motherboard slot and memory type must already be present for this RDIMM to work?

A 288-pin DDR4 registered DIMM slot that supports ECC registered memory is required; unbuffered or non-ECC platforms will not accept this module.
