OWC 32GB DDR4 2666MHz ECC Registered RDIMM 2Rx4 1.2V 288-Pin server RAM

OWC 32GB DDR4 2666MHz ECC RDIMM

This 32GB DDR4 module runs at 2666MHz with CL19 latency and 1.2V operation. It is built as a 288-pin ECC registered RDIMM using a 2Rx4 organisation. The part is designed for servers, workstations and NAS systems that require registered memory with error correction. It will not work in standard desktop computers that accept only unbuffered DIMMs.

JEDEC compliant registered build

The module follows JEDEC standard specifications and is RoHS compliant. It carries no heat spreader, relying on server chassis airflow for cooling. The 288-pin registered interface ensures electrical buffering on the command bus, which allows higher capacities per channel but prevents mixing with unbuffered memory in the same system. Backward compatibility covers 2133MHz and 2400MHz bus speeds.

Replaces Supermicro MEM-DR432L modules

This OWC part matches the specifications of Supermicro MEM-DR432L-SL02-ER26 and MEM-DR432L-SL03-ER26 modules. It serves as a direct replacement for those part numbers when expanding or repairing compatible platforms. The upgrade is worthwhile when the platform supports DDR4 registered ECC memory and the workload benefits from the additional 32GB capacity per slot. Buyers needing unbuffered memory or desktop compatibility should look elsewhere.
