Best RAM for Synology DiskStation DS423+

What RAM to buy and how to install it inside the DS423+.

By default, the Synology DiskStation DS423+ comes from the factory with 2GB of RAM. The Intel processor allows for up to 6GB of DDR4 RAM to be installed, at least according to Synology. This guide will run through the best RAM for Synology DiskStation DS423+, including how to go about installing the modules.

What RAM is supported by Synology DiskStation DS423+

The Intel Celeron J4125 processor found inside the Synology DiskStation DS423+ was released in 2019. According to Intel, the maximum amount of system memory supported by this CPU is 8GB. It’s a potent little 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 the included 2GB of RAM physically soldered on the main PCB. Synology sells its own branded RAM that’s 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.

This official RAM upgrade kit from Synology ensures your NAS will be running at its full potential without any concern of incompatibility. It’s just a little on the expensive side.

How to install RAM in Synology DiskStation DS423+

Installing RAM inside the Synology DiskStation DS423+ is an easy process that doesn’t require any tools. 2GB 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 6GB.

  1. Remove all drive bays from the Synology DiskStation DS423+. (We’ve got a collection of the best NAS drives if you need them.)
  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.
