OWC 1R6T32R416GB 16GB DDR3L 1600 PC3L-12800 CL11 2Rx4 240-pin 1.35V ECC Registered RDIMM server RAM

16 GB DDR3L ECC Registered RDIMM

This 16 GB DDR3L module runs at 1600 MHz with CL11 latency and 1.35 V operation. It uses a 240-pin registered DIMM form factor with 2Rx4 organisation and ECC for error correction. The part is designed for servers, workstations, NAS systems and routers that require registered ECC memory. It replaces several HP part numbers including 684316181, 688963001, 713756081 and 713985B21.

Verify registered ECC DDR3L support

Before ordering, confirm that your system accepts DDR3L registered ECC RDIMMs at 1.35 V. Standard desktop motherboards cannot use registered memory and will not boot with this module. Check the vendor documentation for qualified memory lists and maximum capacity per slot. Do not mix this module with unbuffered or non-ECC DIMMs in the same channel.

Fits 240-pin DDR3L server platforms

The module plugs directly into a 240-pin DDR3L RDIMM slot and draws 1.35 V, reducing power draw compared to standard DDR3. It frees a standard-voltage slot for lower-heat operation in dense configurations. Ensure the platform firmware supports 16 GB registered ranks and that enough slots remain for your target capacity.
