OWC 16GB (2x8GB) DDR3 1066 PC3-8500 CL7 2Rx4 240-pin 1.5V ECC Registered RDIMM server RAM

16GB DDR3 ECC Registered Kit

This dual-channel kit provides 16GB of DDR3 1066 memory built for workstations and servers. It uses registered ECC RDIMMs to maintain data integrity in multi-socket or always-on environments. Standard desktop motherboards cannot use these modules. Buyers needing unbuffered non-ECC memory for a consumer PC should look elsewhere.

Capacity and Headroom

The 16GB total split across two 8GB ranks suits virtualization hosts, database nodes or NAS appliances that benefit from error correction. Registered buffering adds electrical load, so the platform chipset must explicitly support RDIMMs; otherwise the system will not post. Workloads that exceed 16GB or require faster than 1066 MT/s will need higher-capacity or higher-speed kits.

Compliance and Voltage Flexibility

JEDEC and RoHS compliance means the modules meet industry electrical and environmental standards for warranty-safe upgrades. The parts are qualified at both 1.5V and 1.35V, allowing deployment in systems that request either voltage without manual adjustment. No heat spreaders are included, so airflow across the DIMM slots must be adequate for sustained loads.
