Synology NAS DDR3L Upgrade

This OWC module adds 8 GB of DDR3L 1866 memory to compatible Synology DiskStation units. It is built to JEDEC PC3L-14900 CL13 timings and runs at 1.35 V without ECC or buffering.

Fits DS218+ DS418play DS620slim DS718+ DS918+

The 204-pin SODIMM slots straight into the NAS memory socket and requires no configuration changes. Adding capacity frees headroom for simultaneous services such as file sharing, media transcoding and virtual machines.

Ideal for listed DiskStation owners

Buyers with other NAS models or laptops should verify the exact DDR3L 1866 CL13 2Rx8 specification before purchasing. Systems that demand ECC registered DIMMs or a different voltage will not accept this module.

Questions about this item

Does the 1.35V DDR3L module exceed the thermal limit inside a Synology DS918+ running continuously?

The module operates at the standard DDR3L voltage of 1.35V and is listed as compatible with the DS918+, so it stays within the system's thermal design.

How much noise or heat does the 8GB SODIMM add during all-day operation in a DS718+?

The unbuffered DDR3L stick has no heat spreader and draws 1.35V, adding negligible heat and zero acoustic noise to the NAS chassis.

Which specific Synology DiskStation models must I already own for this 204-pin 2Rx8 module to work?

The upgrade is validated for DS218+, DS418play, DS620slim, DS718+ and DS918+; any other system is not confirmed by the manufacturer.
