Synology RackStation RS2418+ memory upgrade

This 8 GB DDR4 2400 module is built for the Synology RackStation RS2418+ and RS2418RP+. It uses ECC unregistered 2Rx8 chips at 1.2 V and CL17 timing to protect data integrity in a NAS environment. The single 288-pin DIMM adds capacity without needing a matched pair.

Who this suits and who should look elsewhere

Ideal for administrators expanding a compatible Synology RackStation up to the platform's 64 GB limit across four slots. Not suited for desktop PCs, laptops or servers that require registered DIMMs, non-ECC memory or a different DDR generation. Buyers needing higher densities per module should consider other configurations.

Sustained-load behaviour

ECC circuitry corrects single-bit errors continuously during long file transfers, RAID rebuilds or backup windows. Unbuffered architecture keeps latency low at the rated 2400 MT/s speed. The module runs at standard 1.2 V without a heat spreader, relying on chassis airflow for thermal stability during extended operation.

Questions about this item

Does my Synology RackStation RS2418+ or RS2418RP+ need free 288-pin DDR4 slots to install this 8 GB ECC module?

Yes, the RS2418+ and RS2418RP+ each have four 288-pin DDR4 slots; at least one must be empty for this stick to fit.

Can I mix this 2400 MHz CL17 2Rx8 ECC DIMM with the original memory that came in my RS2418RP+?

The module runs at DDR4 2400 CL17 1.2 V; the system will down-clock all sticks to the slowest installed kit, so it will work but may run below rated speed.

How do I confirm the RS2418+ recognises the full 8 GB and ECC after I seat the stick?

Open DSM Control Panel → Info Center → Memory; it should show total capacity increased by 8 GB and list the new module as ECC Unregistered.
