OWC 32GB (2×16GB) DDR4 2666 CL19 ECC SODIMM memory upgrade

SKU CH-BRX9-J1E8Z

32 GB DDR4 ECC SODIMM kit for Synology DS3018xs and DS3622xs+ NAS, running at 2666 MHz CL19 1.2 V

  • Capacity32GB (2 x 16GB)
  • Type260-Pin DDR4 ECC SODIMM
  • SpeedDDR4 2666 (PC4 21300)
  • CAS LatencyCL19
  • Voltage1.2V

Capacity 32GB (2 x 16GB)

  • 32 GB capacity lets Synology NAS handle more simultaneous tasks
  • 2666 MHz DDR4 speed with CL19 latency keeps data flowing smoothly
  • ECC protection detects and corrects single-bit errors for data integrity
  • 2 V operation reduces power draw and heat in compact bays
  • Backward compatible with 2400 MHz and 2133 MHz systems for flexible deployment

Synology DS3018xs and DS3622xs+ memory kit

This 32 GB kit contains two 16 GB DDR4 2666 CL19 ECC SODIMM modules built for the Synology DiskStation DS3018xs and DS3622xs+. It adds 32 GB of error-correcting memory to compatible NAS units. The unbuffered 2Rx8 design runs at 1.2 V without a heat spreader.

Check your NAS model and free slots

Verify that your unit is a DS3018xs or DS3622xs+ before ordering. The kit uses 260-pin DDR4 SODIMMs, so the system must accept that form factor. Confirm how many slots are empty; each module occupies one slot. The memory is backwards compatible with 2400 MHz and 2133 MHz buses if the platform requires a lower speed.

Thermals, noise and power in normal use

Operating at 1.2 V, the modules draw minimal power and produce little heat. No heat spreader is fitted, so airflow from the NAS chassis passes directly over the chips. The memory adds no moving parts and makes no audible noise during operation.

Questions about this item

Does the 32 GB kit include both 16 GB modules or do I need to buy a second stick?

The kit contains two 16 GB SODIMMs for a total of 32 GB, so nothing else is required for the DS3018xs or DS3622xs+.

Why choose the 2666 CL19 ECC version over a slower or non-ECC alternative?

The DS3018xs and DS3622xs+ support ECC and run at 2666 MHz; this kit matches that speed, latency and error-correction requirement exactly.

What does the PC4-21300 rating mean for my Synology NAS?

PC4-21300 is the JEDEC designation for DDR4 2666, confirming the modules meet the standard speed and voltage the DS3018xs and DS3622xs+ expect.
