A-Tech 16GB DDR4 2133 ECC RDIMM 2Rx4 for Synology RAMRG2133DDR4-16G Server Memory

SKU CH-0FQQ-1QY2H

16 GB DDR4 2133 ECC RDIMM 2Rx4 server memory module with 1.2 V operation

  • Capacity16GB
  • SpeedDDR4 2133 (PC4 17000)
  • CAS LatencyCL15
  • Voltage1.20V
  • ECCYes
  • Buffered/RegisteredRegistered
  • 16GB capacity expands server memory for heavier workloads
  • DDR4 2133MHz speed with CL15 latency supports responsive data access
  • ECC RDIMM registered design detects and corrects memory errors
  • 2Rx4 dual-rank organisation increases memory density per module
  • 2V standard voltage reduces power draw in compatible systems

Synology-Compatible DDR4 ECC RDIMM

This 16 GB registered DDR4 module is built as a direct replacement for the Synology RAMRG2133DDR4-16G part number. It targets administrators upgrading compatible Synology NAS units or workstations that require ECC registered memory. The single-module design simplifies installation when only one slot is available or when populating channels evenly.

16 GB Capacity with CL15 Latency

The module runs at 2133 MHz (PC4-17000) with a CAS latency of 15 and operates at the standard 1.20 V. ECC and registered buffering provide error correction and signal integrity for multi-module server configurations. Capacity heads-up is reached when the platform's maximum supported memory per slot or total system limit is met.

288-Pin DIMM for Registered Platforms

The 288-pin DDR4 DIMM form factor fits only motherboards and NAS appliances designed for registered ECC memory. It cannot be used in consumer boards that accept only unbuffered non-ECC modules. The registered design reduces electrical load on the memory controller, freeing headroom for larger total memory populations.

Questions about this item

Will this 288-pin DDR4 2133 module run at the correct speed alongside my existing CL15 1.20V sticks?

Yes — it is a 16GB DDR4 2133 (PC4-17000) CL15 1.20V registered ECC DIMM, so it matches the voltage, speed and latency of identical-spec modules already installed.

How can I confirm the system sees the full 16GB registered ECC capacity after installation?

Enter the BIOS or Synology DSM info centre; both will report 16GB detected, show ECC active and list the module as a registered DDR4 2133 DIMM.

Does the single 16GB 2Rx4 stick ship alone or with any brackets or cables?

Only the 288-pin DDR4 RDIMM itself is included; no brackets, cables or additional hardware are supplied.
