The Intel Celeron J4125 processor found inside the Synology DiskStation DS423+ was released in 2019. According to Intel, the CPU supports a maximum of 8 GB of system memory. It’s a potent chip for a NAS thanks to its quad-core configuration and a burst speed of up to 2.7GHz.

The DS423+ has one available DIMM slot with 2 GB of RAM physically soldered on the main PCB. Synology sells branded RAM certified to work on the best NAS such as the DS423+. We’d recommend going with one of them if you’d prefer to rely on Synology for support.

Installing RAM inside the Synology DiskStation DS423+ is an easy process that doesn’t require any tools. 2 GB of DDR4 RAM is already preinstalled from the factory, but this quick guide will show you how to add more modules to bring the total up to 86GB.
