How Much RAM Does an FTB Interactions Server Need?
FTB Interactions is FTB's dungeon-crawling expert pack on Forge 1.12.2, where progress comes from scavenging Aurelia's dungeons for rare technology instead of grinding a standard crafting tree. See the full modpack details on the FTB Interactions pack page. Below is a quick RAM breakdown so you can pick a plan without guessing. 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. Workable for solo play or testing the server pack boots cleanly, but Aurelia's dungeon generation and unique mob AI leave very little headroom once a world is actually running.
8 GB
The best starting point for most FTB Interactions servers. This matches the pack's own recommended floor and comfortably covers the dungeon generation, custom mobs, and salvage-based tech mods together for a small group.
10 GB
Safer for a mid-size, active group running multiple simultaneous dungeon expeditions without the server starting to lag between salvage runs.
12 GB
Recommended for 10+ players or a long-running world with a large explored map, where dungeon chunk loading and accumulated loot/entity data add up over time.
