  • ECCYes
  • Buffered/RegisteredRegistered
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • Voltage1.20V
  • ECC protection prevents data corruption in the Synology FS3400
  • Registered RDIMM design supports stable server operation under load
  • 16 GB capacity expands NAS memory for heavier workloads
  • DDR4 2666 speed matches the system’s rated frequency
  • Low 1.2 V voltage reduces power draw and heat

Synology FS3400 NAS memory upgrade

This 16 GB DDR4 2666 MHz ECC registered DIMM is validated for the Synology FlashStation FS3400. It targets IT teams who need to expand memory capacity in that specific NAS platform without compatibility risk.

288-pin registered module with major OEM chips

The stick uses Samsung, Micron or Hynix components on a standard 288-pin RDIMM PCB. Registered buffering and ECC protect data integrity under sustained workloads, while 1.2 V operation keeps power draw low. No heat spreader is fitted, so airflow in the chassis handles cooling.

Replaces or adds to factory memory in the FS3400

Adding this module increases total system memory for virtualisation, caching or multi-user file services. The upgrade is worth it when the NAS shows memory pressure during peak loads or when new services require more RAM than the original configuration provides.

商品問答

Will the DDR4 2666 PC4-21300 registered ECC module run at its rated speed in a Synology FS3400?

Yes, the module is built to the DDR4 2666 PC4-21300 specification and is validated for the Synology FlashStation FS3400, so it will operate at 2666 MT/s with ECC and registered signalling active.

Does the 288-pin RDIMM fit the memory slots in a Synology FS3400 without a riser or adapter?

The 288-pin DDR4 RDIMM form factor matches the FS3400 DIMM sockets directly; no riser, adapter or special bracket is required.

What is the correct orientation when seating the 1Rx4 ECC RDIMM in the FS3400 slot?

Align the notch on the module with the key in the slot, press down evenly until both retention clips click, and verify the module sits flush — partial seating is the most common error.
