Compatible upgrade for Synology DS1819+

This 16GB DDR4 SODIMM module is built for the Synology DiskStation DS1819+ NAS. It delivers a single 16GB stick that fits the system's 260-pin slots and supports the platform's maximum memory configuration. The module is designed for administrators expanding capacity on this specific model. It is not suited for desktop PCs, laptops or other NAS units that require different form factors or voltage levels.

Unbuffered non-ECC design with major-brand chips

The stick uses unbuffered, non-ECC memory built on a major-brand chipset in a 2Rx8 organisation. It operates at the standard 1.2V DDR4 voltage and installs directly into any of the four available SODIMM sockets without extra cabling or adapters. The low-profile design has no heat spreader, so it clears tight drive bays and chassis lids common in compact NAS enclosures.

CL17 timing at 2400MHz within standard power

Rated at DDR4 2400 (PC4 19200) with 17-17-17 latency, the module runs at the JEDEC-defined speed and voltage for this platform. Power draw stays at the nominal 1.2V level, keeping thermal output low inside the passively cooled DiskStation chassis. Acoustic impact is negligible because the NAS relies on system fans rather than module-mounted cooling.

Perguntas sobre este artigo

Does the DDR4-2400 SO-DIMM run at the full 2400 MHz speed in a Synology DS1819+?

The module is rated for DDR4-2400 (PC4-19200). The DS1819+ memory controller supports up to 2400 MHz, so the stick will operate at its rated 2400 MHz speed.

Will this 260-pin SODIMM fit the four memory slots in a Synology DS1819+?

Yes. The DS1819+ has four 260-pin DDR4 SO-DIMM slots and this stick uses the standard 260-pin SO-DIMM form factor, so it installs directly into any slot.

How is the module installed in the DS1819+, and what step do people often miss?

Power off the NAS, remove the drive trays, open the chassis cover, insert the SODIMM at an angle into a free slot until the gold contacts are hidden, then press down firmly until the side clips click. The step often missed is pressing down hard enough to fully engage both retention clips.
