How Much RAM Does a Chernobyl - Forge Labs Server Need?

Chernobyl - Forge Labs is a Forge 1.19.2 survival challenge pack — see the Chernobyl - Forge Labs pack page for the full mod list — where radiation zones and mutated creatures make RAM sizing matter more than in a typical survival world. 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 solo or duo play — expect noticeable lag once radiation zones and mutated mobs start spawning in numbers.

5 GB

The recommended starting point for Chernobyl - Forge Labs — enough headroom for the mod's radiation tracking and mutation systems without constant garbage collection pauses.

6 GB

A safer bet for a small-to-mid group exploring multiple radiation zones at once, where more chunks stay loaded and active simultaneously.

8 GB

What you want for 10+ players or a world that's been running for weeks, since explored exclusion-zone terrain and mutated-mob data keep accumulating.
