How Much RAM Does a SkyFactory 3 Server Need?

The honest answer is that SkyFactory 3's small skyblock map hides real memory pressure once automation systems grow. For most real groups, 6 GB is where the stress drops and the server starts feeling comfortable — see the SkyFactory 3 pack page for more. 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

Workable for a small group of 5-10 players early on, but tight once Ender IO and Refined Storage systems grow.

6 GB

Best starting point for most SkyFactory 3 servers — gives the garbage collector real breathing room.

8 GB

Safer for a 10-20 player community with heavier automation running continuously.

10 GB

Best for larger servers with extensive, long-running automation setups.
