Synology RS820+/RS820RP+ 16GB DDR4 SODIMM

This NEMIX RAM module adds 16GB of DDR4 2666MHz memory to compatible Synology RackStation units. It uses a 260-pin SODIMM form factor with CL19 latency and 1.2V operation. The single-rank 2Rx8 design is unbuffered and non-ECC for NAS workloads.

Check Synology model and slot availability

Verify the device is a Synology RS820+ or RS820RP+ before ordering. Confirm an empty SODIMM slot exists or plan to replace the existing module. The system must accept non-ECC unbuffered DDR4 SODIMMs at 2666MHz.

Fits NAS memory slot for capacity expansion

The module installs directly into the RackStation SODIMM slot without additional hardware. It increases total memory for virtualisation, caching or multi-user file services. No heat spreader is fitted, so clearance matches the standard slot profile.

商品問答

Does the 16GB SODIMM arrive as a single stick or do I need to buy a second module to reach 16GB?

The package contains one 16GB DDR4 2666MHz CL19 2Rx8 1.2V 260-pin SODIMM, so no additional module is required to get the full 16GB capacity.

Should I choose the 2Rx8 rank version or look for a 1Rx8 alternative for my RS820+/RS820RP+?

The module is built as 2Rx8 using major OEM chips and is validated for Synology RackStation RS820+ and RS820RP+ systems, matching the platform's supported rank configuration.

Will the PC4-21300 2666MHz rating actually run at 2666MT/s once installed in the NAS?

Yes, the SODIMM is rated DDR4 2666 (PC4-21300) and will operate at 2666MT/s CL19 at 1.2V in compatible Synology RS820+/RS820RP+ units.
