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.

There are aftermarket solutions from Crucial, Kingston, and other brands that will work with NAS enclosures such as the DS423+, though your mileage may vary. Some reports have even seen as much as 18 GB of RAM installed (and working!) on the Synology DiskStation DS423+.

Official Synology RAM is the safest and most reliable way to expand the system memory on your Synology DiskStation DS423+. Aftermarket options are cheaper and you could go above what’s specified by Intel and Synology as the maximum for this enclosure.

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.

  1. Remove all drive bays from the Synology DiskStation DS423+.
  2. Install the newly purchased RAM module.
  3. Reinstall the drive bays.

That’s all there is to it! The NAS should boot without a problem so long as the RAM is supported and while we’d recommend running a memory test, it’s not required.
