Synology RS822RP+ 16 GB DDR4 ECC SODIMM

This 16 GB DDR4 2666 ECC unbuffered SODIMM is built for the Synology RackStation RS822RP+. It delivers error-correcting memory in a 260-pin form factor that matches the NAS slot specification. The module runs at 1.2 V with a CAS latency of 19 and uses a 2Rx8 organisation. It is a straightforward capacity upgrade for compatible Synology systems.

Suits RS822RP+ owners adding ECC memory

This module suits administrators who need validated ECC memory for the RS822RP+ and want a single 16 GB stick. It is not for laptops or desktops that require non-ECC SODIMMs. It is also not for systems limited to 8 GB per slot or platforms that only accept registered DIMMs. Buyers needing higher total capacity should verify the maximum supported memory before purchasing.

260-pin DDR4 ECC SODIMM at 2666 MT/s

The decisive specification is the 260-pin DDR4 ECC unbuffered SODIMM interface running at 2666 MT/s (PC4-21300). Only systems that accept this exact module type, voltage and pin count will recognise the memory. Confirm the RS822RP+ memory slot specification matches before ordering.

Questions about this item

What does the 2666 MHz speed mean once this module is installed in a Synology RS822RP+?

The module runs at DDR4 2666 (PC4-21300) inside the NAS, delivering the rated throughput for the system's memory controller.

How does the 260-pin SODIMM interface limit what this memory can do?

The 260-pin DDR4 ECC SODIMM form factor fits only DDR4 SODIMM slots and caps bandwidth at the PC4-21300 rating.

What physical space and slot type does this 16 GB stick need to fit the RS822RP+?

It requires one free 260-pin DDR4 SODIMM slot; the module has no heat spreader and uses a standard low-profile height.
