How Much RAM Does an FTB Sky Odyssey Server Need?
FTB Sky Odyssey (see the FTB Sky Odyssey pack page) spreads players across many floating biome islands instead of one void platform, so RAM needs scale with how much of the sky your group has explored rather than just player count. Here's how to size it correctly from solo play up to a full server. 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. You'll feel it as soon as several floating biome islands need to stay loaded at once.
6 GB
The best starting point for most Sky Odyssey servers. This covers a small group exploring and bridging between islands without constant memory pressure.
8 GB
Safer for a mid-size active group discovering new islands regularly — more biome chunks staying loaded simultaneously as the explored map grows.
12 GB
For 10+ players or a long-running world where dozens of islands have already been discovered and need to stay in memory.
