Synology Inc. 64GB DDR4 ECC RDIMM NAS

64GB DDR4 ECC RDIMM module

This 64GB DDR4 ECC Registered DIMM is built for Synology desktop NAS units that demand high-capacity memory with error correction. The module delivers 64GB of storage-class memory in a single 288-pin package, allowing the system to handle larger datasets and concurrent workloads. Registered buffering reduces the electrical load on the memory controller, helping maintain stability under sustained use. It is intended for administrators who need maximum supported memory in a single slot.

288-pin registered form factor

The 288-pin DIMM form factor provides a secure mechanical and electrical connection to the motherboard socket. Registered buffering lowers the signal load on the memory controller, which supports reliable operation when the NAS is fully populated with memory. ECC circuitry detects and corrects single-bit errors automatically, protecting data integrity during long-running services such as file sharing, backup and virtualization. Using vendor-validated modules avoids the instability that can arise from unqualified memory.

ECC and registered buffering for stability

ECC technology continuously monitors memory transactions and corrects single-bit errors without interrupting the NAS. Registered buffering further steadies the memory subsystem by reducing the electrical demand on the controller, which helps the system sustain performance during heavy multi-user access. The combination of ECC and registered operation is designed for continuous operation in network-attached storage environments where uptime and data accuracy are priorities.
