What this kit is and who it fits

This is a 16GB DDR3L ECC Registered RDIMM kit containing two 8GB modules rated at 1600MHz CL11 and 1.35V. It is built for HP ProLiant BL420c Gen8, BL460c Gen8, BL465c Gen8, BL660c Gen8 and DL160 Gen8 servers and workstations. Buyers who need unbuffered desktop memory or non-ECC modules cannot use this kit.

What to verify before ordering

Confirm that your system requires registered ECC DDR3L RDIMMs and that it accepts 1Rx4 240-pin modules at 1.35V. The memory must not be mixed with unbuffered DIMMs. Check the server documentation to ensure the memory population rules for your specific model support this configuration.

Build quality and daily implications

The modules are manufactured to JEDEC and RoHS standards and carry a limited lifetime warranty with free technical support. They use a standard 240-pin DDR3L form factor without a heat spreader, so they fit the DIMM slots on the listed ProLiant models directly. The registered design adds a clock cycle of latency but improves signal integrity in multi-DIMM server environments.

Questions about this item

Does the kit include two 8 GB DDR3L RDIMMs or do I need to buy them separately?

The kit contains two 8 GB DDR3L 1600 CL11 1.35 V ECC registered RDIMMs, so no additional modules are required for a 16 GB upgrade.

Should I choose this 16 GB DDR3L 1600 CL11 kit or a different capacity for my HP ProLiant BL460c Gen8?

This 16 GB (2×8 GB) DDR3L 1600 CL11 kit matches the HP part numbers 731765B21 and 735302001 and is validated for the BL460c Gen8, making it the correct capacity for that server.

What does the PC3L-12800 1600 MHz rating mean once the modules are installed in a ProLiant DL160 Gen8?

The modules will run at 1600 MHz with CL11 latency at 1.35 V, providing registered ECC bandwidth of PC3L-12800 for the DL160 Gen8 memory controller.
