OWC 16GB DDR3L 1600 ECC RDIMM

This 16GB DDR3L 1600 PC3L-12800 CL11 2Rx4 240-pin 1.35V ECC Registered RDIMM is built for HP ProLiant Gen8 servers including the BL420c, BL460c, BL465c, BL660c and DL160. It replaces HP part numbers 684316181, 688963001, 713756081, 713985B21 and 715284001. The module is not compatible with standard desktop computers and cannot be mixed with unbuffered memory.

Sustained load behaviour

ECC registered operation detects and corrects single-bit errors during continuous workloads, preventing silent data corruption in server and NAS environments. The registered buffer reduces electrical load on the memory controller, helping maintain signal integrity when all DIMM slots are populated. CL11 latency at 1600 MHz delivers steady throughput for virtualisation and database tasks.

Build and connectors

The 240-pin DDR3L form factor fits the Gen8 ProLiant memory slots without a heat spreader, allowing close spacing in dense blade chassis. JEDEC and RoHS compliance ensures the module meets industry voltage and environmental standards. A limited lifetime warranty with free technical support backs the upgrade for long-term deployment. Buyers needing unbuffered ECC or non-ECC UDIMMs for workstations should look elsewhere.

Questions about this item

How much power does the 1.35V DDR3L module draw when the server runs continuously?

At 1.35V the DDR3L module runs cooler than standard 1.5V DDR3, reducing heat output and power draw during all-day operation.

What must the system already have to accept this 240-pin ECC registered RDIMM?

The host must be a workstation or server with DDR3L RDIMM slots that support registered ECC memory; it will not work in standard desktop boards or alongside unbuffered modules.

Can I add this 16GB stick to an HP ProLiant BL460c Gen8 that still uses the original HP 684316181 modules?

Yes, this module replaces HP part numbers including 684316181 and 688963001, so it can be mixed with existing compatible RDIMMs in the same Gen8 server.
