Synology DS1517+ and DS1817+ memory kit

This 16GB kit contains two 8GB DDR3L SODIMM modules built for Synology DiskStation DS1517+ and DS1817+ units. Each stick runs at 1600MHz with CL11 timing at 1.35V. The unbuffered, non-ECC design matches the factory specification for these NAS models.

Upgrade from 8GB or mixed modules

The kit fills both memory sockets to reach the 16GB maximum supported by the DS1517+ and DS1817+. Replacing a single module or mismatched pair eliminates timing conflicts and enables dual-channel operation. The jump is worth it when workloads such as virtualization, container hosting or large file indexing exceed the current capacity.

Fits the two SODIMM slots directly

Installation requires no tools beyond opening the chassis cover. The 204-pin modules seat in the existing slots and draw power at the standard 1.35V DDR3L level. No heat spreader is fitted, so clearance inside the compact NAS chassis is preserved. The kit frees no additional resources but ensures the system can address its full memory ceiling.

Questions about this item

Does the 204-pin DDR3L SODIMM fit the memory slots in a Synology DS1517+ or DS1817+?

Yes, the kit is built for those two DiskStation models and uses the 204-pin SO-DIMM form factor they require.

What is the correct way to seat the two 8 GB modules so the system recognises the full 16 GB?

Insert each stick at a 30-degree angle until the gold contacts disappear, then press down firmly until both side clips click into the notches.

When should I consider replacing these CL11 1.35 V modules?

Replace them if the NAS fails to boot, shows memory errors in DSM logs, or becomes unstable after a firmware update.
