Compatible Synology Upgrade

This 8 GB kit uses two 4 GB DDR3L SODIMM modules validated for Synology RackStation RS818+ and RS818RP+ systems. Each stick runs at 1600 MHz with CL11 timings at 1.35 V. The unbuffered, non-ECC design matches the original specification for these NAS units.

Ideal for RS818 owners

Owners of the listed RackStation models can install this kit to reach the platform maximum of 16 GB across two slots. Builders working with other Synology series, desktop motherboards or laptops should verify their own qualified-vendor lists before purchasing.

Capacity and headroom

The pair fills both sockets and delivers the full 16 GB ceiling supported by the RS818+ and RS818RP+. Workloads that exceed this limit will require a different NAS platform, as the hardware cannot address additional memory.

Questions about this item

Do I need both SO-DIMM slots free in my Synology RackStation RS818+ to install this 2x4GB kit?

The kit contains two 4GB sticks and the RS818+ has two slots, so both slots will be occupied after installation.

Will these DDR3L 1600 CL11 modules run alongside any original DDR3 memory I keep installed?

The RS818+ only has two slots; fitting this 2x4GB kit fills both, leaving no slot for older modules.

How can I verify the 8GB upgrade is recognised at 1600 MHz after installation?

Check the Memory section in DSM Control Panel — it will show 8 GB total and the operating speed of 1600 MHz.
