16 GB DDR3L ECC Registered DIMM

This 16 GB DDR3L module runs at 1333 MT/s with CL9 latency and registered ECC operation. It is built for HPE ProLiant DL370 G6 and SL390s G7 server trays that require HP SmartMemory authentication. The 2Rx4 organisation suits high-density configurations in those platforms.

Check DDR3L slot voltage and registered ECC support

Verify that your server accepts 240-pin DDR3L registered ECC DIMMs and that the BIOS recognises HP SmartMemory qualification. Systems limited to unbuffered or non-ECC memory will not post with this module. Confirm the maximum supported capacity per slot before ordering.

HP SmartMemory authentication enables extended ROM

The module carries HP qualification data that allows compatible ProLiant Gen8 firmware to unlock additional memory performance settings. Without this authentication the server treats the DIMM as standard registered ECC memory. No heat spreader is included, so airflow must meet the chassis specification.

Questions about this item

Does the HP 627812-B21 kit include any brackets or tools, or is it only the memory module?

The kit contains a single 16 GB DDR3L 1333 registered ECC DIMM; no brackets, screws or tools are included.

How do I decide between the 16 GB registered ECC module and a smaller unbuffered alternative for my ProLiant?

Choose this 16 GB 2Rx4 registered ECC part when your HPE ProLiant DL370 G6 or SL390s G7 tray requires registered memory; unbuffered modules will not work in those systems.

What does the PC3L 10600 rating mean for actual throughput once the DIMM is installed?

PC3L 10600 indicates a peak transfer rate of 10 600 MB/s at 1333 MT/s; real-world bandwidth will be lower due to CL9 latency and system overhead.
