32GB DDR4 ECC RDIMM for Synology DP7200/DP7400

This 32GB DDR4 2666 CL19 ECC Registered RDIMM is built for Synology ActiveProtect DP7200 and DP7400 appliances. It delivers error-correcting registered memory for server and NAS workloads that require data integrity. The single 2Rx4 module operates at 1.2V and conforms to JEDEC PC4-21300 specifications.

Install in supported bays; avoid mixing memory types

Installation follows standard 288-pin DIMM insertion into the appliance's memory slots. The module is a warranty-safe upgrade when used in the listed Synology systems. It will not work in standard desktop computers and must not be mixed with unbuffered or load-reduced ECC memory, as doing so prevents boot or causes instability.

DDR4 2666 with 2133/2400 backward compatibility

The module runs at DDR4 2666 (PC4-21300) with CL19 latency and drops to 2133MHz or 2400MHz when the system requires lower speeds. It is limited to platforms that accept registered ECC DDR4 RDIMMs and cannot be used in consumer desktop or laptop memory controllers.
