Best RAM Upgrade for Synology DS923+ (2026 Guide)

Best RAM upgrades for the DS923+

Three sensible tiers depending on your budget and how hard you push Docker, virtual machines, or multi-user file serving.

Which should you pick

Why RAM matters more than CPU headroom here

The DS923+ uses an AMD Ryzen R1600, a capable dual-core chip for a NAS in this class, but it is not paired with a GPU that handles video transcoding. That means the RAM upgrade path is really about running services well, not about squeezing out extra transcoding performance. More memory helps DSM cache frequently accessed files, lets Docker containers run without swapping, and gives Synology's indexing services (Photos, Universal Search) room to work without slowing down file transfers over the two 1GbE ports.

Because the two SO-DIMM slots support up to 32GB combined, and the unit ships with a single 4GB stick, your realistic upgrade paths are either adding one 8GB or 16GB module alongside the factory stick, or removing it and fitting a matched pair for dual-channel operation. For most home users and small offices, 12GB to 16GB is the practical sweet spot rather than maxing out at 32GB, which mainly benefits users running several VMs or memory-hungry surveillance station setups across many camera channels.

Be honest about transcoding before you buy
