OWC 16GB DDR4 ECC UDIMM for Synology SA3200D

This single 16GB DDR4 2666MHz ECC unbuffered DIMM is built for the Synology RackStation SA3200D. It targets administrators who need error-correcting memory to protect data integrity in NAS, server or workstation workloads.

Fits 288-pin DDR4 slots and runs at 1.2V CL19

The module uses the standard 288-pin UDIMM form factor and operates at 1.2 volts with CL19 latency. It requires a platform that supports DDR4 ECC unbuffered memory and frees a slot by delivering 16GB in one stick.

Replaces 2133MHz or 2400MHz DDR4 ECC UDIMMs

Backward compatibility with 2133MHz and 2400MHz modules means this 2666MHz kit can upgrade slower ECC memory. The jump is worth it when the system can run at the higher speed and the workload benefits from extra bandwidth.

Questions about this item

What is the CAS latency of the DDR4 2666MHz ECC UDIMM under sustained load?

The module runs at CL19 latency, which remains constant during continuous operation.

How much power does the 1.2V 16GB ECC UDIMM draw when the NAS runs all day?

It operates at the standard DDR4 voltage of 1.2V, keeping heat output low in a Synology RackStation SA3200D.

Which specific Synology model must I already own for this 288-pin 2Rx8 DIMM to work?

This upgrade is validated for the Synology RackStation SA3200D.
