How Much RAM Does a RAD3 Server Need?
Roguelike Adventures and Dungeons 3 is the third entry in the RAD series, now on Forge 1.20.1 with the largest modlist of the series — see the Roguelike Adventures and Dungeons 3 pack page for the full details. It's a different Minecraft version from RAD and RAD2, so here's exactly how much RAM this specific entry needs. 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.
5 GB
Bare minimum for solo or a couple of players exploring casually — RAD3's dungeon generation and RPG leveling mods leave very little headroom at this size, so expect to upgrade quickly.
7 GB
The starting point we'd actually recommend — this is the RAM floor RAD3's own modlist is built around, enough for the overworld dungeon generation and RPG leveling systems to run without constant garbage collection pressure.
10 GB
Safer for a mid-size active group exploring multiple dungeons at once — gives the largest modlist in the RAD series comfortable room as more chunks and loot tables get generated.
14 GB
For 10+ players or a long-running world — RAD3's RPG progression and dungeon states accumulate over time, and a world that's been explored for weeks needs more memory than a fresh one.
