System-Specific DDR3 ECC RDIMM Kit

This OWC kit provides 16 GB of DDR3 1333 registered ECC memory in a matched pair of 8 GB modules. It is designed for Dell PowerVault NX300 and NX3000 storage servers that require 240-pin DDR3 RDIMMs. The modules operate at 1.5 V with CL9 latency and a 2Rx4 organisation. They are not compatible with standard desktop or consumer laptop platforms.

Compatibility Check Before Ordering

Verify that your target system is a Dell PowerVault NX300 or NX3000 and that it accepts registered ECC DDR3 RDIMMs. Unbuffered or non-ECC modules will not work in these servers and mixing registered with unbuffered memory is unsupported. Confirm the platform has available 240-pin DIMM slots and that the BIOS or firmware supports the full 16 GB capacity across two slots.

Build Quality and Daily Use

Each module uses a standard 240-pin DDR3 PCB without a heat spreader, relying on server chassis airflow for cooling. The registered design adds a buffer that reduces electrical load on the memory controller, improving stability in multi-DIMM configurations. Installation follows the usual DIMM ejection-lever procedure; no special tools or cables are required beyond opening the server chassis.

Questions about this item

Does the 16GB kit include both 8GB modules or must I buy a second kit?

The kit contains two 8GB modules for a total of 16GB, so no additional purchase is required.

Should I choose the 2Rx4 registered ECC version or an unbuffered alternative for my PowerVault NX3000?

The NX3000 requires registered ECC memory; unbuffered modules will not work in this system.

Will the DDR3 1333 CL9 modules run at their rated 1333MHz speed once installed in the PowerVault NX300?

Yes, the modules operate at DDR3 1333 (PC3-10600) with CL9 latency when installed in compatible PowerVault systems.
