3 Things to Know About the TerraMaster F4-423's RAM Limit

The F4-423 supports up to 32 GB of RAM across two SO-DIMM slots, despite shipping with only 4 GB of DDR4.

If you plan to do more than basic file serving—like Plex transcoding, Docker, or lightweight VMs—upgrading the RAM on day one is worth it.

The 32 GB cap is a hard limit, so don’t expect to exceed it with larger modules.
