16 GB DDR3 ECC RDIMM for servers

This 16 GB DDR3 1333 module is an ECC registered DIMM built for select workstations and servers. It targets IT professionals maintaining or expanding DDR3-based enterprise systems. Standard desktop computers cannot use this memory type.

Registered 240-pin design requires matched DIMMs

The registered 240-pin form factor demands a motherboard that supports ECC RDIMMs and cannot be mixed with unbuffered modules. OWC recommends populating all slots with identical capacity, speed and manufacturer to ensure stability. This constraint frees the builder from debugging mismatched memory errors.

JEDEC and RoHS compliant single module

The single 16 GB stick meets JEDEC standards and RoHS requirements for a warranty-safe upgrade. No heat spreader is included, so airflow in the chassis must handle thermal management. The module ships alone without additional accessories or software.

Questions about this item

How much power does the 1.5V DDR3 1333 RDIMM draw when the server runs continuously?

The module operates at 1.5V, the standard voltage for DDR3 1333 registered DIMMs. Actual system power depends on the platform's memory controller and total DIMM count.

What existing hardware is required for this 16GB 2Rx4 ECC registered module to function?

A workstation or server motherboard with 240-pin DDR3 slots that supports ECC registered (RDIMM) memory. It will not work in standard desktop boards or alongside unbuffered DIMMs.
