How Much RAM Does an FTB StoneBlock 2 Server Need?
FTB StoneBlock 2 is a Forge 1.12.2 pack that spawns you inside a single block of solid stone — tunnel out and build your entire base underground, with no open world above. It's the direct predecessor to FTB StoneBlock 3, which carries the same concept forward to 1.18.2; StoneBlock 2 instead runs an older but deep 1.12.2 tech mod lineup. 8 GB is the realistic starting point, and the FTB StoneBlock 2 pack page has the measured 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.
4 GB
Bare minimum for a solo player poking around — expect it to struggle once the tech mod stack gets going.
8 GB
Best starting point for most FTB StoneBlock 2 servers — the pack's own recommended RAM floor.
10 GB
Safer once a few players are tunneling and running machines at the same time.
12 GB
Best for larger groups running multiple tech lines across a heavily tunneled-out underground base.
