Server memory upgrade

This OWC kit supplies 16 GB of DDR3 ECC registered memory in two 8 GB modules built for HP ProLiant G6 servers. It targets administrators who need to extend the service life of a DL320 G6 DL360 G6 DL380 G6 ML330 G6 or ML350 G6 without replacing the platform.

Capacity and headroom

The 16 GB total gives headroom for virtualisation hosts running multiple guests or database workloads that exceed the factory 8 GB configurations. Workloads that demand more than 16 GB or require faster than 1333 MT/s will hit the ceiling of this kit.

Thermals noise and power

Modules operate at 1.5 V without heat spreaders relying on the server chassis airflow for cooling. Registered buffering adds a small latency penalty but keeps the electrical load on the memory controller low. Power draw stays within the standard DDR3 envelope for the platform.

Questions about this item

Will these 2Rx4 registered ECC modules run alongside the original 1Rx4 DIMMs already in my ProLiant DL380 G6?

Mixing registered and unbuffered DIMMs is not supported; the kit must be used with other registered ECC modules of the same 2Rx4 organisation and 1.5 V rating.

How can I confirm the kit is running at DDR3 1333 CL9 after installation?

The server POST screen and BIOS memory information will show 1333 MT/s, CL9 timings and 1.5 V operation for each 8 GB module.

Does the 16 GB kit include only the two 240-pin RDIMMs or are any tools or cables supplied?

The box contains the two 8 GB DDR3 1333 ECC registered RDIMMs and nothing else; no tools, cables or heat spreaders are included.
