OWC 8GB DDR4 2666MHz ECC SODIMM for Synology FS1018

SKU CH-0GE8-3XBW0

Adds 8 GB of DDR4 2666 ECC SODIMM memory to the Synology FS1018 for error-corrected reliability

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

Capacity 8GB

  • 8GB capacity expands NAS multitasking headroom

  • ECC protection guards data integrity
  • 2V operation keeps power draw low
  • Backward compatible with 2400MHz and 2133MHz systems

Synology FS1018 memory upgrade

This OWC module adds 8GB of DDR4 2666 ECC SODIMM capacity to the Synology FlashStation FS1018. It runs at PC4-21300 speed with CL19 latency and 1.2V operation. The unbuffered 1Rx8 design fits the system's 260-pin slots directly.

Suited for FS1018 expansion

NAS administrators who need more memory for virtual machines, Docker containers or heavy file-serving workloads will benefit. Buyers whose units already have the maximum supported memory or who require registered DIMMs should look elsewhere.

Fits the FS1018 slot

The module installs in the native SODIMM socket without adapters or tools. Its JEDEC-standard timings allow backward compatibility with 2400MHz and 2133MHz operation if the system requires it. No heat spreader means clearance is not a concern.

Questions about this item

Does the Synology FS1018 need any specific slot or firmware to accept this 260-pin DDR4 ECC SODIMM?

The module is designed for the FS1018 and fits its standard 260-pin DDR4 SODIMM slots; no extra firmware step is mentioned.

Will this 2666 MHz CL19 stick run stably if I keep my existing 2400 MHz or 2133 MHz modules in the other slots?

Yes — the spec lists backward compatibility with 2400 MHz and 2133 MHz, so the new module will downclock to match the slower sticks.

How can I confirm the 8 GB ECC module is recognised and error-correcting after installation?

Check the Synology DSM information panel — it should show 8 GB at 2666 MHz with ECC status reported as active.
