32GB DDR4 2666 ECC RDIMM for Synology FS3600

This 32GB registered DDR4 module runs at 2666MHz with CL19 latency and 1.20V operation. It is built for the Synology FlashStation FS3600 NAS and uses 2Rx4 organisation with ECC for data integrity. The 288-pin RDIMM form factor fits the validated memory slots in that platform.

Sustained-load behaviour with registered ECC

Registered buffering reduces electrical load on the memory controller during continuous NAS workloads such as file serving, backup and virtualization. ECC corrects single-bit errors on the fly, preventing silent data corruption under heavy, prolonged throughput. The 1.20V rating keeps power draw stable during extended operation.

Build and daily handling

The module has no heat spreader, so it relies on system airflow for cooling inside the FS3600 chassis. Major OEM chips from Samsung, Micron or Hynix are used depending on supply. The 288-pin RDIMM keying prevents accidental insertion into non-ECC or unbuffered slots, ensuring correct installation every time.

Questions about this item

How much power does this 1.2 V DDR4 ECC RDIMM draw under continuous load in the FS3600?

The module operates at 1.20 V standard DDR4 voltage; actual power draw depends on the NAS workload and the FS3600 memory controller.

What must my Synology FS3600 already have for this 288-pin registered DIMM to be recognised?

The FS3600 must support DDR4 2666 MHz ECC registered memory and provide a free 288-pin RDIMM slot.

Will this CL19 2Rx4 module work alongside the original FS3600 memory if I keep the factory sticks installed?

Yes, provided the existing modules are also DDR4 2666 MHz ECC registered; the system will run all sticks at the lowest common speed and latency.
