OWC 16GB DDR4 2666 ECC RDIMM

This 16GB DDR4 2666 MHz PC4-21300 ECC Registered RDIMM is built for servers, workstations and compatible NAS systems such as the Synology SA6400. It delivers error-correcting registered memory for workloads that demand data integrity.

Verify platform compatibility before ordering

Your motherboard or NAS must support DDR4 ECC Registered RDIMMs; this module will not work in standard desktop computers that require unbuffered memory. It also cannot be mixed with unbuffered or load-reduced ECC DIMMs, so confirm the existing population rules for your specific system.

JEDEC-standard build with registered buffer

The 288-pin module operates at 1.2V with CL19 latency and a 2Rx4 organisation, conforming to JEDEC and RoHS standards. No heat spreader is fitted, allowing dense DIMM spacing in qualified server and NAS chassis. Backward compatibility with 2133 MHz and 2400 MHz systems is supported.
