ECC Registered DDR4 for Synology FlashStation

This 32GB DDR4 2666 module is an ECC registered RDIMM built for Synology FlashStation FS3400, FS3410 and FS3600 servers. It runs at 1.2V with CL19 timing and uses a 288-pin 2Rx4 layout. The memory meets JEDEC and RoHS standards for warranty-safe installation.

Suits servers needing registered ECC.

This module targets administrators upgrading or repairing the listed FlashStation models where registered ECC memory is required. It will not work in standard desktop computers or in systems that accept only unbuffered or load-reduced DIMMs. Buyers needing unbuffered memory or consumer form factors should look elsewhere.

Single 32GB DIMM with lifetime support

The package contains one 32GB stick and no additional cables, brackets or software licences. OWC provides a limited lifetime warranty with free technical support and an advanced replacement programme. No bundled utilities or management tools are included with this memory upgrade.

Questions about this item

What Synology FlashStation model must I have for this 32 GB DDR4 2666 ECC RDIMM to work?

The module is validated for Synology FlashStation FS3400, FS3410 and FS3600 servers; it is not compatible with standard desktop PCs or unbuffered memory slots.

Will this CL19 registered DIMM run correctly if I keep existing 2133 MHz or 2400 MHz modules in the same server?

Yes, the kit is backward compatible with 2133 MHz and 2400 MHz DDR4 ECC registered memory, so it will down-clock to match the slower modules.

How can I verify the 32 GB module is recognised at 2666 MHz with ECC active after installation?

Check the Synology DSM Resource Monitor or BIOS memory information; it should show 32 GB, 2666 MT/s, CL19 timings and ECC registered status.
