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.

Questions about this item

What comes in the box and do I need anything else to install the 1R6T32R416GB module?

The box contains the 16GB DDR3L 1600 PC3L-12800 CL11 2Rx4 240-pin 1.35V ECC Registered RDIMM. No extra parts are required; install it directly into a compatible 240-pin DDR3L server or workstation slot.

Should I choose this 16GB DDR3L 1600 CL11 2Rx4 registered kit or a different capacity for my HP server?

This 16GB module matches HP part numbers 684316181, 688963001, 713756081, 713985B21 and 713985B211. Select it when your system requires a 2Rx4 registered DDR3L 1600 DIMM at 1.35V.

What does the PC3L-12800 1600MHz CL11 rating mean once the RAM is running in my workstation?

It delivers a peak transfer rate of 12800 MB/s at 1600 MT/s with a CAS latency of 11 cycles, operating at the JEDEC-standard 1.35V for DDR3L registered ECC server memory.
