Server ECC Registered Upgrade

This OWC kit provides 32GB of DDR4 2666 ECC Registered memory in a dual-channel 2x16GB configuration. It targets administrators upgrading Synology FlashStation FS3400, FS3410 or FS3600 units and other compatible server or workstation platforms that require registered DIMMs.

Straightforward DIMM Installation

The 288-pin modules seat in standard DDR4 RDIMM slots without tools or heat spreaders to remove. Systems that expect unbuffered or load-reduced ECC memory will not accept these registered sticks, so verifying the motherboard manual before purchase avoids a mismatch.

Steady Throughput Under Load

Rated at PC4-21300 with CL19 timings at 1.2V, the modules maintain spec-defined bandwidth during extended workloads. Backward compatibility with 2133MHz and 2400MHz buses allows deployment in mixed-speed chassis without down-clocking surprises.

Perguntas sobre este artigo

How can I verify the 32GB kit is running at 2666 MT/s with ECC after installation?

Check the BIOS or UEFI memory information screen — it should show 32GB total, 2666 MT/s speed, CL19 timings and ECC Registered status for each 16GB module.

What comes in the box and what must be purchased separately?

The box contains two 16GB DDR4 2666 ECC Registered RDIMM modules (part 2R6D42R4032P); no additional parts or cables are included.

Which capacity or speed version should I choose for a Synology FS3400, FS3410 or FS3600?

This 32GB (2×16GB) DDR4 2666 CL19 kit matches the Synology D4RD-2666-16G and D4ER01-16G specs and is validated for FS3400, FS3410 and FS3600.
