The Synology DiskStation DS923+ is kitted out with 4GB of DDR4 RAM from the factory, but the AMD CPU allows the enclosure to be upgraded to a maximum of 32GB. Deciding which modules to use is important as you don’t want to get it wrong and waste money or risk damaging the NAS. We’ve got you covered with the best RAM for Synology DiskStation DS923+.
What RAM is supported by Synology DiskStation DS923+
The AMD Ryzen R1600 processor is a powerful server CPU that can support up to 32GB of DDR4 RAM. It has two cores that are capable of boosting up to 3.1GHz, making it ideal for running a busy NAS for the home or office. 4GB of RAM is usually enough to get you started, but a higher capacity will allow you to do more.
Two DIMM slots are available on the NAS and one has the 4GB module preinstalled. This can be easily extracted and replaced with two 16GB DDR4 DIMMs to bring the total up to 32GB. The best NAS allows one to upgrade and expand the RAM so it’s good to see the DS923+ capable here.

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+.

One reply on “Best RAM for Synology DiskStation DS923+”
Thanks for the article, tips and links. I have a question. DS923+ comes with 4GB pre-installed (one module) can I add a second memory card of any capacity (4GB, 8GB, 16GB) or must the two memory banks contain the same size of memory card 2 x 4GB, 2 x 8GB… up to 2 x 16GB ?
