CMS 4GB DDR4 2400MHz SODIMM for DS1819+

This module is a 4GB DDR4 2400MHz non-ECC SODIMM built to upgrade the Synology DiskStation DS1819+. It targets NAS owners who need to expand memory capacity within the platform's supported limits for improved multitasking and caching performance.

Straightforward SODIMM installation

Insert the 260-pin stick into an available slot at a slight angle until the side clips engage. The unbuffered 1.2V design requires no configuration in DSM. The only common issue is exceeding the four-slot, 32GB maximum, so verify current population before adding this kit.

32GB total capacity ceiling

The DS1819+ accepts up to 32GB across its four SODIMM sockets. This single 4GB module fits that constraint, but buyers who want more storage than the platform allows should consider a different NAS chassis.

Questions about this item

How can I confirm the 4GB DDR4 2400MHz module is recognised by my Synology DiskStation DS1819+ after installation?

Power on the NAS, open DSM and go to Control Panel > Info Center; the Memory section should show the new 4GB stick and the updated total capacity.

What does the package contain and is anything else required to install the CM512642400SO in a DS1819+?

The box includes one 260-pin SODIMM stick; no extra parts or tools are needed — just open the memory bay and insert the module.

The DS1819+ supports up to 32GB across four slots — which capacity should I choose if I want to reach that maximum?

Populate all four slots with 8GB modules; this 4GB stick adds capacity but cannot reach the 32GB limit on its own.
