Synology NAS 32GB DDR4 ECC Kit

This 32GB kit delivers two 16GB DDR4 2666 SODIMM modules with ECC and a CL19 latency. It runs at 1.20V and uses the 260-pin unbuffered form factor. The kit is validated for Synology DiskStation DS1621+ systems.

Upgrade from lower-capacity or non-ECC SODIMMs

Replacing smaller or non-ECC modules with this 2Rx8 kit adds error correction and doubles density per slot. The jump is worth it when the NAS handles ZFS pools, virtual machines or heavy multi-user workloads that demand data integrity.

Suits DS1621+ owners needing maximum supported ECC

Builders using consumer laptops, non-ECC motherboards or platforms limited to 16GB per slot should look elsewhere. Buyers who require registered DIMMs, higher speeds or capacities beyond 32GB will need a different memory class.

Questions about this item

Does this kit use the standard 260-pin SODIMM form factor for my Synology DS1621+?

Yes, each module is a 260-pin DDR4 ECC SODIMM that fits the DS1621+ memory slots directly.

Do I need to configure anything in the BIOS after installing both 16GB sticks?

No BIOS setup is required; the NAS detects the 32GB kit automatically at 2666 MT/s CL19.

Will the Samsung, Micron or Hynix chips on these modules need active cooling later?

The modules have no heat spreader and run at 1.2 V, so passive airflow inside the chassis is sufficient.
