How Much RAM Does a SkyFactory 4 Server Need?
SkyFactory 4 is Darkosto's classic void-skyblock on Forge 1.12.2 — the most-played SkyFactory version with millions of downloads, and lighter and faster to boot than SkyFactory 5. The SkyFactory 4 pack page has the measured RAM floor behind it. 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.
3 GB
Workable for a solo or duo island, but tight once automation and prestige resets pile up.
5 GB
Best starting point for most SkyFactory 4 servers — the pack's own recommended floor.
6 GB
Safer once a small community is running overlapping automation setups on their islands.
8 GB
Best for larger groups with multiple islands and heavy automation running at once.
