Synology FS1018 memory kit

This OWC kit delivers 32 GB of DDR4 ECC SODIMM memory in two 16 GB modules built for the Synology FlashStation FS1018. It runs at 2666 MHz with CL19 latency and 1.2 V operation. The unbuffered 2Rx8 design meets JEDEC and RoHS standards for a warranty-safe upgrade.

Capacity and headroom

The 32 GB total capacity lets the FS1018 handle larger file caches, more concurrent virtual machines and heavier database workloads without swapping. Dual-rank 2Rx8 organisation provides density for the platform's four slots. Systems needing more than 32 GB or registered DIMM support cannot use this kit.

Thermals noise and power

Modules operate at the standard 1.2 V DDR4 voltage with no heat spreaders, relying on the NAS chassis airflow for cooling. Passive operation adds no audible noise. Power draw stays within the platform's default memory budget so no extra power provisioning is required.

Questions about this item

Will these 2666 MHz modules run stably alongside my existing 2400 MHz DDR4 sticks in the FS1018?

Yes, the kit is backward compatible with 2400 MHz and 2133 MHz DDR4, so it will clock down to match the slower modules already installed.

How can I verify the ECC function is active after installing the 2Rx8 SODIMMs?

Check the Synology DSM Resource Monitor or system log; it will report ECC memory detected and show corrected error counts if any occur.

Does the 32 GB kit include only the two 16 GB SODIMMs or are tools and cables supplied?

The box contains only the two 260-pin DDR4 ECC SODIMM modules; no tools, cables or additional hardware are included.
