How Much RAM Does a Better MC [FABRIC] BMC2 Server Need?
Better MC [FABRIC] BMC2 is a vanilla+ exploration and performance pack on Fabric 1.20.1 — see the Better MC [FABRIC] BMC2 pack page for the full mod list. It sits between BMC1 (1.19.2 Fabric) and BMC3 (also 1.20.1 Fabric), with its own distinct set of mods, so its RAM needs don't automatically match either sibling. 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.
2 GB
Below BMC2's own recommended floor. You can sometimes boot here for a quick solo test, but expect slow chunk loading and a higher chance of mods failing to initialize under memory pressure.
4 GB
Best starting point for most servers. This matches BMC2's own recommended RAM floor and comfortably covers the full mod list for a small group exploring together.
6 GB
Safer for a mid-size active group — gives Fabric and the BMC2 mod list more breathing room as more chunks stay loaded and more players explore simultaneously.
8 GB
For 10+ players or a long-running world — keeps performance steady as the explored map grows and more terrain and chunk data need to stay cached.
