OWC 16GB DDR3L 1600 ECC Registered RDIMM 2Rx4 1.35V memory upgrade

Server Memory Upgrade

This OWC 16GB DDR3L 1600 ECC Registered RDIMM is built for HP ProLiant Gen8 servers including the DL360e, DL360p, DL380p, DL385p and DL580. The module delivers 16GB capacity at PC3L-12800 speed with CL11 latency and 1.35V operation. It uses a 240-pin 2Rx4 registered design with on-board error correction for data integrity in critical workloads. The part replaces HP numbers 684316181, 688963001, 713756081, 713985B21, 713985B211 and 715284001.

Replaces Standard DIMMs

The registered ECC design replaces unbuffered non-ECC modules in supported ProLiant Gen8 platforms where data accuracy and signal stability are required. The jump is worth it when expanding memory capacity beyond the limits of consumer DIMMs or when the system firmware demands registered modules for multi-DIMM configurations. It cannot be mixed with unbuffered memory and will not function in standard desktop computers or workstations that lack registered memory support.

Sustained Load Behaviour

Under continuous operation the DDR3L 1.35V rating reduces power draw and heat output compared to standard 1.5V DDR3, helping maintain stability during extended compute tasks. The registered buffer lowers electrical loading on the memory controller, which preserves signal quality when multiple modules populate the server's DIMM slots. JEDEC and RoHS compliance ensures consistent timing and thermal characteristics across long production runs.
