How Much RAM Does a TerraFirma: Rebirth Server Need?

TerraFirma: Rebirth rebuilds TerraFirmaCraft's geological survival on Forge 1.20.1 using TerraFirmaCraft+, and its RAM needs scale with how much terrain your group explores and surveys rather than just player count. See the TerraFirma: Rebirth pack page for the full pack details. 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 a solo player or a duo testing TerraFirmaCraft+'s early game, but expect longer chunk loading during world generation and little headroom for extra mods.

6 GB

TerraFirma: Rebirth's own recommended floor on Forge 1.20.1. Comfortable for a small group (2-5 players) working through the slow stone-age start without automation to lean on.

8 GB

Safer for a mid-size, active group (6-10 players) exploring more terrain and surveying more ore veins at once.

12 GB

Recommended for 10+ players or a long-running world where TerraFirmaCraft+'s rock layer and climate data has accumulated across a large explored area.
