How Much RAM Does a TerraFirmaAdventure Server Need?
TerraFirmaAdventure pairs TerraFirmaCraft's geology-driven survival with dungeon mods and custom structures on Forge 1.20.1, which makes it heavier on RAM than a typical TFC server — see the TerraFirmaAdventure pack page for the full mod list. Below are the memory tiers we'd actually recommend, from a bare-minimum solo boot up to a long-running server with 10+ players. 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
Technically boots solo, but TFC's geology simulation plus the added dungeon and exploration content will fight over memory — expect long chunk loading pauses and tight margins the moment you open a backpack full of ore.
7 GB
This is the floor we'd actually recommend starting from. It gives TFC's world generation and metallurgy simulation room to run alongside the pack's dungeon and structure mods without constant garbage collection pauses.
10 GB
A safer target once you've got a handful of players actively prospecting, smelting, and exploring the added structures at the same time — more headroom for simultaneous chunk generation.
16 GB
Where you want to be for a long-running world with 10+ players, since TFC worlds only grow heavier over time as more terrain gets explored and more of the adventure content gets generated.
