Synology RS822+ 32 GB DDR4 ECC kit

This 32 GB kit contains two 16 GB DDR4 2666 ECC unbuffered SODIMM modules built for the Synology RackStation RS822+. Each stick runs at 1.20 V with CL19 timing and uses a 260-pin layout. The modules are validated for NAS workloads that require error-correcting memory.

NAS owners adding ECC capacity

The kit suits administrators who need to expand an RS822+ to its supported memory limit with guaranteed compatibility. Builders working on non-Synology platforms or systems that require registered DIMMs should choose a different module type.

2Rx8 dual-rank organisation

Each 16 GB module uses a 2Rx8 configuration that the RS822+ memory controller recognises without manual setup. Single-rank or registered alternatives will not provide the same density in this chassis.

Questions about this item

How much power does the 1.2V DDR4 2666 kit draw when the NAS runs continuously?

Each 16GB module operates at 1.2V, the standard DDR4 voltage, so the pair adds minimal power draw to the RS822+ during all-day operation.

Does the Synology RS822+ need any firmware update or extra bracket before I install these 260-pin SODIMMs?

No extra bracket or firmware is required; the 260-pin ECC unbuffered SODIMMs slot directly into the RS822+ memory sockets.

Will the CL19 2Rx8 modules work alongside the original 8GB stick that came with my RS822+?

The RS822+ has two SODIMM slots, so the factory 8GB module must be removed to fit this 32GB (2x16GB) kit.
