OWC 8GB DDR4 2666MHz ECC SODIMM 1Rx8 1.2V memory upgrade

SKU CH-V1KC-223P2

An 8 GB DDR4 ECC SODIMM rated at 2666 MHz CL19 for Synology DS3018xs and DS3622xs+ NAS systems

  • Total capacity8 GB
  • Rated speedDDR4 2666 (PC4 21300)
  • CAS latencyCL19
  • Rated voltage1.2 V
  • Buffer typeUnbuffered
  • Memory rank1Rx8

Capacity 8GB

  • 8GB capacity expands NAS memory for heavier workloads
  • DDR4 2666MHz speed with CL19 latency delivers responsive performance
  • ECC protection detects and corrects data errors automatically
  • 2V low voltage reduces power draw and heat
  • Validated for Synology DS3018xs and DS3622xs+ compatibility

Synology NAS Memory Upgrade

This 8GB DDR4 2666MHz ECC SODIMM is built for Synology DiskStation DS3018xs and DS3622xs+ systems. It uses a 260-pin unbuffered layout with CL19 timing and 1.2V operation. The module adds error-correcting reliability to compatible NAS units.

Replaces Slower DDR4 Modules

The stick runs at PC4-21300 speed and is backwards compatible with 2400MHz and 2133MHz slots. Upgrading is worthwhile when the NAS handles heavier workloads or more concurrent users than the original capacity allows. It will not benefit systems that already have sufficient memory for their workload.

Fits 260-Pin SODIMM Slots

The single-rank 1Rx8 design occupies one memory slot without a heat spreader. It requires a platform that accepts DDR4 ECC unbuffered SODIMMs at 1.2V. The upgrade leaves any additional slots free for further expansion if the chassis supports it.

Questions about this item

Does this 260-pin DDR4 SODIMM fit the memory slots in a Synology DiskStation DS3018xs or DS3622xs+?

Yes, the module is a 260-pin DDR4 ECC SODIMM validated for both the DS3018xs and DS3622xs+ NAS systems.

What is the correct way to seat this ECC SODIMM, and what step do people often miss?

Insert the module at the proper angle until the gold contacts are fully hidden, then press down firmly until the side clips click into place; the step often missed is verifying both clips are fully latched.

Will this 8 GB DDR4 2666 MHz CL19 1.2 V ECC SODIMM need any firmware updates or component replacements during its service life?

No firmware updates are required for the memory itself, and the module has no user-replaceable parts; it is designed to operate for the lifetime of the NAS without maintenance.
