There aren’t many NAS enclosures from Synology with an Intel Xeon processor and the Synology DiskStation DS3622xs+ is a special server. Coming with 16GB of RAM out of the box and support for up to 36 drive bays with expansion units, you can do a lot with this black slab of metal.
What RAM is supported by Synology DiskStation DS3622xs+
Powered by the Intel Xeon D-1531 processor, the Synology DiskStation DS3622xs+ is capable of using up to 128GB of DDR4 RAM. This enclosure officially supports 48GB of RAM with four DIMM slots.
The modules you should consider are DDR4-2666 with ECC. 16GB is preinstalled from the factory, leaving two available DIMM slots. Installing a further 32GB will bring the capacity up to 48GB.
16GB of DDR4 RAM is a healthy amount for even the best NAS, but installing an additional 32GB makes for quite the server. With this much system memory, one would be able to install and run various applications with numerous simultaneous connections.
Best RAM for Synology DiskStation DS3622xs+
Synology D4ES02-8G
Synology offers its official RAM modules for branded NAS enclosures. They’re expensive but you will have peace of mind and full support from the company should an issue arise down the line. This kit would double the available memory of the DS1522+.

v-Color makes some great affordable RAM for PCs and the company also makes some memory modules for servers, including NAS. Not only does this 32GB kit save you money (and lots of it), but some DS1522+ owners have managed to go up to 64GB. We’ve not confirmed the modules work so your mileage may vary.
How to install RAM in Synology DiskStation DS3622xs+
Installing RAM inside the Synology DiskStation DS3622xs+ is a simple process that requires the removal of the top and side panels. The two available slots can be located on the left side. One is populated by the preinstalled 8GB module.
I’d recommend running a memory test on the purchased RAM using an available PC, if possible, before installing them inside the NAS.
- Remove the top panel.
- Remove the side panel.
- Install the newly purchased RAM module(s) into the free slots.
- Reattach the side panel.
- Reattach the top panel.
That’s all there is to it! Simply power up the NAS and double-check Synology DSM is seeing the full capacity installed.
