How Much RAM Does a Fabri's Frontiers Server Need?
Fabri's Frontiers is a Fabric exploration pack for 1.20.1 that layers Terralith, Nullscape, and several custom dimensions on top of each other, with progression gated behind dimensional unlocks — see the Fabri's Frontiers pack page for the full mod list. Here's how much RAM each tier of server actually needs. 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 play or a tiny group of two. It's enough to boot the pack and explore one dimension at a time, but Terralith and Nullscape's chunk generation will feel sluggish as more dimensions get unlocked.
6 GB
The best starting point for most Fabri's Frontiers servers. This is the pack's own recommended floor once all of its world-generation mods and custom dimensions are running, and it holds up well for a small-to-medium group exploring at a normal pace.
8 GB
Safer for a mid-size active group pushing into multiple custom dimensions at once. More headroom for simultaneous chunk generation across dimensions keeps things smooth when several players are exploring different areas.
12 GB
For 10+ players or a long-running world where most dimensions have already been unlocked and explored. More loaded chunks and a larger persistent world across all dimensions benefit from the extra headroom.
