How Much RAM Does a MineColonies Server Need?
MineColonies Official is the official NeoForge 1.21.1 modpack from the MineColonies team, with 1.6M downloads — recruit NPC workers, assign them jobs, and expand your settlement from a tiny outpost to a walled city. The MineColonies pack page has the measured RAM floor behind it. Finnish players: Minecraft-palvelin hosting is our native-language page. German players: Minecraft-Server mieten covers the same hosting auf Deutsch. Svenska spelare: Hyra Minecraft-server täcker samma hosting på svenska.
4 GB
Workable for a solo or duo colony, but tight once more than a handful of NPC workers are active.
6 GB
Best starting point for most MineColonies servers — the pack's own recommended floor.
8 GB
Safer once a settlement grows and several players are recruiting and building at once.
10 GB
Best for larger groups running a walled city with heavy NPC pathfinding load.
