Synology NAS DDR3L Upgrade Kit

This OWC memory kit provides 8 GB of DDR3L SODIMM RAM in a matched pair of 4 GB modules. It is built for Synology NAS models DS1817+, RS818+, RS818RP+ and RS1219+ that accept 204-pin unbuffered non-ECC memory running at 1.35 V. The kit replaces Synology part number RAM1600DDR3L-4GBx2 and meets JEDEC PC3L-12800 specifications.

Ideal for DS1817+ and RS Series Owners

The modules suit administrators who need to expand the installed memory in the listed Synology units to support more concurrent services or larger file caches. It is not for systems that require ECC error correction, registered DIMMs, a different voltage than 1.35 V, or a pin count other than 204. Buyers with other NAS brands or desktop motherboards should verify their platform's exact memory requirements before purchasing.

Deciding Specification: PC3L-12800 CL11 at 1.35 V

The single figure that determines compatibility is the JEDEC speed grade PC3L-12800 with CL11 latency at 1.35 V. Only NAS appliances that specify this exact DDR3L standard will accept the kit without configuration issues. Confirm that your Synology model documents support for PC3L-12800 1.35 V SODIMMs before ordering.

Questions about this item

Is the 8 GB kit the only capacity OWC offers for these Synology models?

The product listed here is an 8 GB kit made up of two 4 GB modules; no other capacities are mentioned for this part.

What does the 1600 speed rating mean once the modules are installed in a DS1817+?

The modules run at DDR3L 1600 with CL11 latency at 1.35 V, matching the NAS memory specification.

Does the 204-pin DDR3L interface limit the upgrade in any way?

The kit uses standard 204-pin DDR3L SODIMMs, the form factor required by the DS1817+, RS818+, RS818RP+ and RS1219+.
