Synology RS1619xs+ 64GB DDR4 ECC Kit

This 64GB kit contains four 16GB unregistered ECC DIMMs built for the Synology RackStation RS1619xs+. Each module runs at DDR4 2400 with CL17 timing at 1.2V. The 288-pin design fills all four memory slots in the NAS.

Upgrading from lower-capacity DDR4 ECC modules

The jump is worth it when the RS1619xs+ hits its 64GB memory ceiling and workloads such as virtualisation or heavy file caching need the maximum addressable space. Replacing smaller sticks with this 4x16GB set reaches that limit in a single step.

Build integration for the RS1619xs+

Installation uses the four native DIMM slots and requires no registered or buffered memory support. The kit frees no additional slots because the platform maximum is 64GB across four sockets. No heat spreaders are included, so airflow in the rack chassis handles cooling.

Questions about this item

Does the 288-pin DDR4 DIMM fit the four slots in the Synology RS1619xs+?

Yes, each 16 GB module uses the standard 288-pin DDR4 form factor that matches the four DIMM sockets in the RS1619xs+.

What is the correct order for inserting the four unregistered ECC sticks?

Populate all four slots with the matching 2Rx8 modules; the system will recognise the full 64 GB kit automatically.

Will the 1.2 V DDR4 2400 modules need any firmware update or battery change later?

No firmware or battery maintenance is required; the ECC DIMMs run at 1.2 V and are covered by the manufacturer's limited lifetime warranty.
