How Much RAM Does a Create: Superflat Survival Server Need?
Create: Superflat Survival strips away caves, ores, and natural terrain on Forge 1.20.1, so every resource comes through Create machines, villager trading, or alternative generation — see the Create: Superflat Survival pack page for the full mod list. That shifts the memory load away from terrain generation and onto constant automation: contraptions, mixers, and fans running non-stop use more RAM than the flat world's missing caves ever would. 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
Enough for solo testing or a single player exploring the pack's automation chains, but Create's contraption rendering leaves very little headroom — expect slowdowns the moment a second player joins.
6 GB
CoalHost's recommended floor for Create: Superflat Survival and the best starting point for most servers — covers the automation load of a small group running machines, mixers, and fans at the same time.
10 GB
Safer for a mid-size active group running several automation lines in parallel, since Create's contraptions and item-processing chains stack memory use fast once multiple players are building at once.
16 GB
Recommended for 10+ players or a long-running world with a sprawling factory floor — by that point the pack's automation footprint, not terrain, is what drives memory use.
