  • ChipsetMajor Brand Chipset
  • CAS latencyCL17
  • Memory timings17-17-17
  • Rated voltage1.2 V
  • ECC protection prevents data corruption in your Synology RS3618xs
  • 2400 MHz DDR4 speed delivers 19200 MB/s bandwidth for demanding workloads
  • CL17 17-17-17 timing optimises latency for responsive NAS operation
  • 2 V operation reduces power draw and heat in 24/7 rack environments
  • 288-pin unregistered DIMM installs directly into the four memory slots

Target system and module role

This 8GB DDR4 ECC unregistered DIMM is built for the Synology RackStation RS3618xs. It adds a single 8GB stick to the four-slot chassis, which supports a maximum of 64GB. The module suits administrators who need error-correcting memory for data integrity in a NAS environment.

Installation notes and common issues

The 288-pin DIMM installs directly into any available slot without tools. Because the system requires ECC unregistered memory, mixing registered or non-ECC modules will prevent boot or disable error correction. Verify the existing population before adding this stick to keep all channels in the same mode.

Sustained-load behaviour

Rated at 2400MHz with CL17 timings and 1.2V operation, the module runs within standard DDR4 power limits during continuous file serving or backup workloads. The major-brand chipset and 2Rx8 organisation deliver stable throughput without a heat spreader, relying on the chassis airflow to maintain temperature during extended use.

Questions about this item

How can I confirm the 8 GB DDR4 2400 ECC module is recognised correctly after installing it in my Synology RS3618xs?

Open Synology DSM, go to Control Panel > Info Center and verify the total memory shows the added 8 GB running at 2400 MHz with ECC active.

What ships with the CM1024722400ECCNR kit and is anything else required for installation?

The box contains one 288-pin DDR4 DIMM; no extra cables, brackets or tools are needed to seat it in the RS3618xs.

Which capacity should I choose if my RS3618xs has four slots and supports 64 GB maximum?

Each 8 GB stick adds 8 GB; populate all four slots with matching modules to reach the 64 GB limit.
