Server-grade DDR3 kit

This OWC kit supplies 64 GB of DDR3 1333 ECC registered memory in four 16 GB modules. It targets administrators maintaining HP ProLiant DL585 G7, ML370 G6, SL160s G6 or SL160s G7 servers. The registered design and error-correcting code suit workloads that demand data integrity over raw speed. Standard desktop boards cannot use these modules.

Build integration

Each 240-pin RDIMM runs at 1.5 V with CL9 latency and a 2Rx4 organisation. The kit plugs directly into the supported ProLiant slots without adapters or configuration changes. Because the modules are registered and ECC, they must not be mixed with unbuffered memory in the same system. The upgrade frees the existing DIMM population for redeployment or spare inventory.

Upgrade context

The kit replaces smaller or slower DDR3 sets in the listed ProLiant generations, raising total capacity to 64 GB across four slots. The jump is worth it when virtualisation, database caching or multi-tenant workloads exceed the current memory ceiling. Servers already running mixed-rank or non-ECC modules cannot benefit without a full swap.

商品問答

How does the CL9 latency at DDR3 1333 speed affect throughput when the server runs at full load?

CL9 at 1333 MHz sets the baseline timing for each memory cycle; lower latency would improve response but this kit matches the JEDEC standard for the rated speed.

Will the registered ECC modules run hotter or draw more power than unbuffered DIMMs during continuous operation?

Registered DIMMs add a small buffer load, but at 1.5 V and without heat spreaders they stay within normal DDR3 thermal limits for server chassis airflow.

Which HP ProLiant models must I already own for this 4 x 16 GB kit to be compatible?

The kit is validated for HP ProLiant DL585 G7, ML370 G6, SL160s G6 and SL160s G7 servers.
