How Much RAM Does a Create Comes Alive Server Need?
Create Comes Alive combines Create, MineColonies, and MCA Reborn into a tight three-mod pack on Forge 1.20.1, and RAM needs scale with how far your colony and villager relationships have grown — see the Create Comes Alive pack page for the full modlist. 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.
3 GB
Bare minimum for solo or a tiny 1-2 player test — tight for Create's simulation plus MineColonies and MCA Reborn running together, expect occasional slowdowns as a colony grows.
5 GB
Best starting point for most Create Comes Alive servers — matches the pack's own recommended floor and gives Create, MineColonies, and MCA Reborn enough headroom to run together without constant garbage collection pressure.
7 GB
Safer for a mid-size active group with a growing colony and several villagers tracked by MCA Reborn, plus a handful of larger Create contraptions running at once.
10 GB
For 10+ players, a sprawling MineColonies colony, and a long-running world with heavy Create automation and a lot of MCA Reborn relationship data accumulated over time.
