How Much RAM Does a SpacePotato Backrooms Revamped Server Need?
SpacePotato Backrooms Revamped is a Backrooms horror exploration pack built on Fabric 1.20.1, and its liminal-space corridor generation makes RAM sizing a little different from a typical Minecraft modpack. If you want the full rundown of what's included, check the SpacePotato Backrooms Revamped pack page first. 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
The bare minimum for solo exploration — the Backrooms dimension generation and entity AI from SPB-Revamped leave almost no headroom, so expect slow chunk loads and occasional stutters even alone.
5 GB
The recommended starting point for SpacePotato Backrooms Revamped. This matches the pack's own RAM floor and comfortably covers the Fabric 1.20.1 base, the SPB-Revamped mod, and normal corridor generation for a small group.
8 GB
A safer tier for a mid-size group actively exploring multiple corridor branches at once, since the liminal-space generation keeps more chunks loaded simultaneously as players spread out.
12 GB
Recommended for 10+ players or a long-running world where the explored Backrooms map keeps growing — more generated corridors and entities in memory means more headroom to stay stable.
