NEMIX RAM 64GB (4x16GB) DDR4 2666 ECC RDIMM CL19 1.2V 288-pin Synology SA3600 memory upgrade

Synology SA3600 64GB kit

This 64GB kit contains four 16GB DDR4 2666 registered DIMMs built for the Synology SA3600 NAS. Each module runs at 1.2V with CL19 latency and includes on-die ECC for data integrity. The registered design reduces electrical load on the memory controller for stable operation in multi-slot configurations. IT teams use this kit to expand capacity for virtualisation and file workloads.

Upgrade from smaller or non-ECC kits

The kit replaces lower-capacity unbuffered or non-ECC modules that cannot address the SA3600's full slot population. Registered signalling is required when all four slots are populated, so the jump is worth it when the system needs the full 64GB addressable space. Builders who need consumer DIMMs or unregistered memory should look elsewhere.

Sustained load behaviour

Modules are stress tested under load before shipping to verify stability during continuous NAS operations. The 1.2V operating voltage keeps thermal output consistent during extended file transfers or backup windows. Without a heat spreader, airflow across the 288-pin PCB manages temperatures in the SA3600 chassis. The 1Rx4 organisation maintains bandwidth efficiency across all populated channels.
