NEMIX RAM 8GB DDR4 2666 ECC SODIMM Synology DS3622xs+

SKU CH-V36A-69DAK

Adds 8 GB DDR4-2666 ECC SODIMM to Synology DS3622xs+ for data-integrity memory expansion

  • Capacity8GB
  • SpeedDDR4 2666 (PC4 21300)
  • ECCYes
  • Buffered/RegisteredUnbuffered
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • Voltage1.20V
  • ECC protection prevents data corruption in NAS workloads
  • 2666 MHz DDR4 speed matches DS3622xs+ specifications
  • 20 V low-voltage operation reduces power draw
  • 260-pin SODIMM form factor fits Synology memory slots
  • 1Rx8 single-rank layout simplifies installation

Synology DS3622xs+ compatible memory

This 8 GB DDR4 2666 ECC SODIMM is built for the Synology DiskStation DS3622xs+ NAS. It adds 8 GB of error-correcting capacity in a single unbuffered module. The 260-pin form factor matches the system memory slots exactly.

Low-voltage operation at 1.2 V

Running at 1.20 V keeps power draw modest and heat output low inside the NAS chassis. No heat spreader is fitted, so the module relies on the system airflow. CL19 latency at 2666 MT/s delivers stable throughput for typical file and backup workloads.

Single-rank 1Rx8 layout for straightforward upgrades

The 1Rx8 organisation uses major OEM chips from Samsung, Micron or Hynix. One 8 GB stick occupies a single slot, leaving remaining bays free for future expansion. ECC protection helps guard data integrity during continuous NAS operation.

Perguntas sobre este artigo

How do I install this 260-PIN DDR4 ECC SODIMM in the Synology DS3622xs+ and what step is often missed?

Power down the NAS, remove the cover, insert the module at an angle into the SODIMM slot until the clips lock, then reassemble; the step often missed is confirming the 1.20V module seats fully before powering on.

What maintenance or replacement will this 1Rx8 ECC unbuffered module need over time?

No scheduled maintenance is required; ECC corrects single-bit errors automatically, and the module should only be replaced if the NAS reports uncorrectable memory errors or fails POST.

What limit appears first on this CL19 2666 MHz module under sustained workloads?

The CAS latency of 19 cycles at 2666 MHz sets the access-time floor, so sustained random reads hit that timing ceiling before bandwidth saturates.
