How Much RAM Does an FTB StoneBlock 3 Server Need?
StoneBlock 3 is FTB's tunnel-out-of-solid-stone progression pack — tighter scope than a kitchen-sink pack, but don't let that fool you on RAM: a live boot test showed it actually fails to boot at 8 GB and needs 12 GB, documented on the FTB StoneBlock 3 pack page. 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.
8 GB
Fails to boot — measured directly, not a guess. Don't size StoneBlock 3 like a normal 8 GB pack.
12 GB
Boots clean — this is StoneBlock 3's actual recommended floor, confirmed by a live boot test.
14 GB
Comfortable headroom once several players are tunneling and automating at once.
16 GB
Best for larger groups or a world that runs for months of progression.
