System-specific upgrade for DS1819+

This 8 GB DDR4 SO-DIMM is built for the Synology DiskStation DS1819+ and matches the platform’s 2400 MHz memory bus. The unbuffered, non-ECC module uses a 260-pin layout and runs at 1.2 V with CL17 timings. It installs in one of the four available sockets to raise total capacity toward the 32 GB maximum.

Sustained-load behaviour

The 2Rx8 organisation and major-brand chipset keep throughput steady during long file-indexing jobs or multi-user database workloads. Rated at PC4 19200 bandwidth, the stick delivers consistent read/write cycles without throttling when the NAS runs continuous background tasks such as backup replication or media transcoding.

Thermals, noise and power

Operating at the standard 1.2 V DDR4 voltage, the module adds minimal heat inside the sealed chassis and requires no heat spreader. Passive cooling from the system’s existing airflow keeps temperatures low, so fan speed and acoustic output remain unchanged. The low power draw also preserves the unit’s overall energy efficiency during 24/7 operation.

Questions about this item

Does the 1.2 V DDR4 2400 MHz module run hot or loud inside a DS1819+ that operates 24/7?

The SODIMM has no heat spreader and draws only 1.2 V, so it adds negligible heat and makes no noise in a continuously running DiskStation.

What must the Synology DS1819+ already have free to accept this 260-pin SODIMM?

The NAS needs at least one empty DDR4 SO-DIMM slot among its four sockets and must not already be at the 32 GB maximum.

Will this CL17 2Rx8 stick work alongside the original memory that shipped with my DS1819+?

Yes — it matches the factory DDR4 2400 MHz, non-ECC, unbuffered spec, so it will run in dual-channel with the existing modules.
