Synology RS822RP+ compatible DDR4 ECC SODIMM kit

This 16GB kit contains two 8GB DDR4 2666 unbuffered ECC SODIMM modules built for the Synology RS822RP+ NAS. The kit targets administrators who need validated memory for that specific rackstation and want error-correcting code protection for data integrity.

16GB dual-channel capacity with CL19 latency

The 2 x 8GB configuration fills two slots and runs at 1.20V with CL19 timings, delivering 16GB of ECC-protected memory for typical NAS workloads such as file serving, backup and virtualization. Systems requiring more than 16GB or higher frequencies will exceed this kit's capacity and speed limits.

DDR4 2666 SODIMM interface constraints

The modules use the 260-pin DDR4 SODIMM form factor at 2666 MT/s, so they only fit platforms that accept unbuffered DDR4 ECC SODIMMs at that speed. Boards limited to slower DDR4 speeds, registered DIMMs, or non-ECC memory cannot use this kit.

Questions about this item

Will this kit run at 2666 MHz alongside the original 8 GB module already in my RS822RP+?

The kit is rated DDR4 2666 (PC4-21300) CL19 1.20 V; the NAS will clock all installed modules to the lowest common speed, so the original module and the new 2 x 8 GB sticks will run together at 2666 MHz.

How can I confirm the RS822RP+ recognises the full 16 GB and ECC function after install?

Power on the unit, open Control Panel > Info Center, and verify Total Physical Memory shows 16 GB with ECC Status reported as Enabled.

What exactly ships in the box and is anything else required to fit the modules?

The package contains two 8 GB 260-pin DDR4 ECC unbuffered SODIMMs; no extra parts or tools are included, and the NAS chassis provides the only hardware needed for installation.
