Server ECC RDIMM upgrade

This OWC module provides 16GB of DDR3L registered memory with ECC for workstations, servers and NAS systems. It runs at 1600MHz with CL11 latency and 1.35V operation. The 240-pin RDIMM format uses a 2Rx4 organisation for data integrity in multi-module configurations.

Registered DDR3L platform limits

ECC registered DIMMs require a motherboard and chipset that support registered signalling and error correction. They will not function in standard desktop boards that accept only unbuffered memory. Mixing registered and unbuffered modules on the same platform is not supported.

16GB 2Rx4 capacity per slot

Each module delivers 16GB in a dual-rank x4 layout, so total system memory scales with the number of populated slots. Buyers needing higher density per DIMM or a different rank organisation should verify their platform's maximum supported configuration before ordering.
