How Much RAM Does a Just Create SMP 2 Server Need?
Just Create SMP 2 is the official NeoForge 1.21.1 modpack for Just Create SMP Season 2 — see the Just Create SMP 2 pack page for the full mod list. Because it's built around Create's continuous kinetic simulation for a real multiplayer season rather than a generic solo Create sandbox, RAM needs scale with player count faster than you might expect. 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
Bare minimum for solo testing or a quick look at the pack — tight for Create's kinetic simulation, expect stutter once more than one or two machines are running.
5 GB
The recommended starting point for Just Create SMP 2 — matches the pack's own RAM floor and comfortably runs Create's mechanics plus the QoL mods for a small group.
8 GB
Safer for a mid-size active group running multiple Create contraptions at once across the SMP season.
12 GB
For 10+ players and a long-running season world with heavy Create factories and an expanding base map.
