Target systems

This 32 GB kit consists of two 16 GB DDR3L ECC registered DIMMs built for HP ProLiant BL465c G7 and DL980 G7 servers. It runs at 1600 MHz with CL11 latency and 1.35 V, matching the JEDEC PC3L-12800 standard for low-voltage server memory.

Replaces HP parts

The modules replace HP part numbers 684316181, 688963001, 713756081, 713985B21 and 715284001. The upgrade is worthwhile when the existing configuration uses smaller registered ECC DIMMs or unbuffered memory that cannot be mixed with registered modules.

Capacity and limits

The dual-rank 2Rx4 organisation provides 32 GB total, suitable for virtualisation workloads and large datasets on supported platforms. Systems requiring higher densities or newer DDR generations will need a different memory architecture.

Questions about this item

Will the 240-pin DDR3L RDIMM modules fit the DIMM slots on an HP ProLiant BL465c G7?

Yes, the kit uses the standard 240-pin DDR3L registered DIMM form factor required by the BL465c G7 and DL980 G7.

What is the correct order for populating the two 16 GB modules during installation?

Install the modules in the lowest-numbered DIMM slots of each memory channel as shown in the server’s service guide; the most common error is placing both sticks in the same channel.

If a module fails years later, can I replace just one 16 GB stick or must I swap the pair?

Each 16 GB module is individually tested and covered by OWC’s limited lifetime warranty, so a single stick can be replaced without returning the full kit.
