OWC 16GB DDR3L 1600 CL11 ECC Registered RDIMM 240-pin 1.35V 2Rx4 memory upgrade

Server-grade ECC memory

This 16GB DDR3L registered DIMM adds error-correcting capacity to compatible HP ProLiant servers. It operates at 1600MHz with CL11 latency and a low 1.35V voltage. The module uses a 2Rx4 organisation and a 240-pin form factor. It is designed for workloads that require data integrity and registered buffering.

Thermals and power draw

The DDR3L voltage of 1.35V reduces power consumption compared with standard DDR3 modules. No heat spreader is fitted, so airflow across the PCB handles thermal dissipation. Registered buffering adds minimal electrical load to the memory controller. Typical server chassis airflow keeps temperatures within JEDEC limits during normal operation.

Sustained load behaviour

ECC registered architecture maintains signal integrity across all ranks during continuous read and write cycles. The single 16GB rank configuration avoids interleaving delays under heavy multi-threaded workloads. CL11 timing remains stable without voltage scaling. The module replaces HP part numbers 684316181, 688963001, 713756081, 713985B21, 713985B211 and 715284001 for validated compatibility.
