OWC 32GB DDR4 2666MHz ECC Registered RDIMM 2Rx4 CL19 1.2V 288pin memory upgrade

32GB DDR4 ECC RDIMM for Supermicro X11SRA

This 32GB DDR4 2666MHz ECC Registered RDIMM is built for Supermicro X11SRA, X11SRA-F and X11SRA-RF motherboards. It delivers 288-pin registered memory with error correction for servers, workstations and NAS systems that require data integrity. The module runs at 1.2V with CL19 latency and a 2Rx4 rank configuration. It is not compatible with standard desktop computers or unbuffered memory.

Replaces Supermicro MEM-DR432L series modules

This module replaces Supermicro part numbers including MEM-DR432LC-ER26, MEMDR432LCL01ER26 and related LCL, LHL and LSL variants. The upgrade is worth it when existing memory is at capacity or when adding ECC protection to a supported platform. Backward compatibility with 2133MHz and 2400MHz systems allows installation in older DDR4 slots while running at the lower speed.

Fits X11SRA platforms with registered DIMM slots

The RDIMM installs directly into 288-pin registered DIMM slots on the listed Supermicro boards. No heat spreader is included, so airflow in the chassis should be adequate for dense configurations. Using registered ECC memory frees the memory controller from single-bit error handling and enables larger total capacities per channel. Mixing with unbuffered DIMMs is not supported.
