How Much RAM Does a Prehistoric World Server Need?
Prehistoric World packs Fossils and Archaeology Revival, Prehistoric Fauna, and custom Mesozoic-era biomes onto Forge 1.20.1, which makes RAM sizing a bit different from a typical survival pack — see the Prehistoric World pack page for the full mod list. 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
The bare minimum for solo play or testing the pack before inviting anyone — expect slower chunk loading when custom biomes generate and little headroom if you add more mods.
6 GB
The recommended starting point for most Prehistoric World servers — enough headroom for Fossils and Archaeology Revival, Prehistoric Fauna, and custom biome generation to run smoothly for a small group.
8 GB
A safer choice for a mid-size active group exploring ancient ruins and taming dinosaurs across multiple biomes at once.
12 GB
Needed for 10+ players or a long-running world where dinosaur populations, tamed creatures, and explored terrain keep accumulating.
