OWC 32GB (2x16GB) DDR4 2666MHz CL19 ECC SODIMM memory upgrade

SKU CH-XRN7-VP8CT

A 32 GB dual-channel kit of 2666 MHz DDR4 ECC SODIMM modules validated for Synology DS2419+ and DS2419+II NAS systems

  • Total capacity32 GB (2 × 16 GB)
  • Rated speedDDR4 2666 (PC4 21300)
  • CAS latencyCL19
  • Rated voltage1.2 V
  • Buffer typeUnbuffered
  • Memory rank2Rx8

Capacity 32GB (2 x 16GB)

  • 32 GB kit expands NAS capacity for heavier workloads
  • Dual 16 GB modules enable dual-channel throughput
  • DDR4 2666 MHz CL19 matches system-rated speed
  • ECC protection guards data integrity in critical storage
  • JEDEC 1.2 V standard keeps power draw low

Targeted NAS Memory Upgrade

This 32GB kit supplies two 16GB DDR4 2666MHz CL19 ECC SODIMM modules built for Synology DiskStation DS2419+ and DS2419+II systems. It runs at 1.2V using unbuffered 2Rx8 chips on a 260-pin form factor.

Suited For Verified Synology Models

Ideal for administrators expanding memory in the listed DiskStation units to handle heavier workloads or virtualization. Not suited for builders needing non-ECC memory, DIMM form factors, speeds above 2666MHz, or capacities beyond 32GB per kit.

Verify Slot Count And Maximum Capacity

Confirm your NAS has two free SODIMM slots and supports 32GB total before ordering. The modules are backward compatible with 2400MHz and 2133MHz operation, but the system must accept ECC unbuffered DDR4 SODIMMs.

Questions about this item

Which Synology DiskStation models must I already own for this 32 GB DDR4 2666 MHz ECC SODIMM kit to work?

This kit is validated for Synology DiskStation DS2419+ and DS2419+II NAS systems.

Will the 2666 MHz CL19 modules run correctly if my DS2419+ currently has 2400 MHz or 2133 MHz memory installed?

The modules are backwards compatible with 2400 MHz and 2133 MHz speeds, so they will operate at the lowest common frequency when mixed.

How can I verify the 32 GB ECC upgrade is recognised and running at 2666 MHz after installation?

Check the Synology DSM Resource Monitor or the boot-time memory summary; it should show 32 GB total capacity, ECC enabled, and 2666 MHz speed.
