Synology RackStation RS2423+ memory upgrade

This 16GB DDR4 ECC UDIMM is built for the Synology RackStation RS2423+ and RS2423RP+. It targets administrators who need to expand system memory for virtualisation, container workloads or large file caches. The module installs in a standard 288-pin DIMM slot without tools.

16GB capacity with DDR4 2666 CL19 headroom

The single 16GB rank runs at 2666MHz with CL19 latency at 1.2V. It also operates at 2133MHz and 2400MHz if the platform requires a lower speed. ECC protection corrects single-bit errors, which matters for data integrity in NAS services. Capacity stops at 16GB per module; larger DIMMs are not covered by this part.

JEDEC compliance and lifetime support

The module meets JEDEC and RoHS standards, keeping the original system warranty intact. OWC supplies a limited lifetime warranty with an advanced replacement programme and free technical support. An installation video is available for first-time builders. No heat spreader or extra software is included.

商品問答

Will this 2666 MHz DDR4 ECC UDIMM run reliably in a Synology RS2423+ that currently has 2133 MHz modules installed?

The module is backward compatible with 2133 MHz and 2400 MHz systems, so it will operate at the speed of the slowest installed DIMM while maintaining ECC function.

How can I confirm the 16 GB ECC UDIMM is recognised and error-correcting after installation in my RackStation?

Check the DSM Resource Monitor memory section; it should show the new 16 GB capacity and report ECC status as active with zero correctable errors.

Does the single 288-pin DIMM ship with any mounting hardware or tools, or must I supply them?

The package contains only the 16 GB DDR4 2666 MHz CL19 2Rx8 1.2 V ECC unbuffered UDIMM; no brackets, screws or tools are included.
