128 GB DDR4 ECC RDIMM kit for Synology FS3400

This NEMIX RAM kit delivers 128 GB across four 32 GB registered DIMMs, validated for the Synology FlashStation FS3400 NAS. Each module runs at DDR4 2666 (PC4-21300) with CL19 latency at 1.20 V.

Suited for FS3400 owners who need ECC registered

The 2Rx4 organisation and 288-pin RDIMM form factor match the FS3400 memory controller requirements. Systems that require unbuffered UDIMMs or non-ECC modules cannot use this kit.

Registered ECC with 2Rx4 organisation

The modules are registered ECC RDIMMs built with a 2Rx4 rank configuration, a requirement for the FS3400 memory subsystem. Unregistered or single-rank alternatives will not function in this platform.

Perguntas sobre este artigo

What does the Synology FS3400 require to accept this 128 GB DDR4 2666 ECC RDIMM kit?

The FS3400 must support DDR4 2666 registered ECC memory in a 288-pin RDIMM form factor and have four available DIMM slots for the 4 x 32 GB modules.

How will this CL19 1.2 V kit behave if the FS3400 already has slower DDR4 ECC RDIMMs installed?

The memory controller will run all populated slots at the lowest common speed and highest latency, so the new 2666 MHz modules will down-clock to match the existing DIMMs.

How can I confirm the FS3400 recognises all 128 GB at 2666 MHz with ECC active after installation?

Check the Synology DSM Resource Monitor or the boot-time POST screen; both report total capacity, operating frequency and ECC status for each installed module.
