Synology packs the DiskStation DS920+ with some considerable firepower, including an Intel processor, 4GB of RAM, and four drive bays. If you did need a little more performance, it’s technically possible to upgrade the RAM to 8GB. This guide will show you how.
How to upgrade RAM on Synology DiskStation DS920+
It’s possible to upgrade the RAM on the Synology DiskStation DS920+ in but a few steps. All you need is a compatible module (see Synology’s website) and the NAS powered down to gain access to the available memory slot.
- Power down the Synology DiskStation DS920+.
- Take out the four hard drive bays.
- The RAM slot is located on the side where the power button is.
- Take out the newly purchased RAM from its packaging.
- Carefully insert the module into the slot, matching the notch to that on the module.
- Re-insert the hard drive bays.
I’d recommend running through the following steps after installing a module:
- Open up Synology Assistant.
- Click the cog icon in the top-right.
- Enable “Memory test”.
- Right-click the Synology DiskStation DS920+ on the list to start the memory test.
If you fancy yourself more RAM than what’s officially supported, it has been known for 16GB modules to work on the DiskStation DS920+. I’m going to include the 4GB module here that is guaranteed by Synology to work without an issue.

Synology D4NESO-2666-4G
This 4GB RAM module runs at 2666MT/s and is ideal for giving the DS920+ a considerable bump in performance. Just ignore the relatively high price tag.
