How Much RAM Does a Project Ozone 3 Server Need?
Project Ozone 3: A New Way Forward is a massive Forge 1.12.2 skyblock modpack with three difficulty modes — Titan, Normal, and Kappa — and hundreds of dimensions plus thousands of quests to work through over a playthrough built to last months. See the Project Ozone 3: A New Way Forward pack page for the full feature rundown. 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.
8 GB
The bare minimum for a solo or two-player test run, and only on Normal mode in the early game before dimensions start piling up — expect slowdowns once loot games and extra dimensions load in.
16 GB
The best starting point for most Project Ozone 3 servers — matches the pack's own recommended floor and covers Titan mode's early automation along with a small group's first dimensions.
20 GB
Safer for a mid-size active group running quests and loot games across several dimensions at once, especially on Titan mode where recipe chains stack up fast.
24 GB
For 10+ players or a long-running world working toward prestige — with hundreds of dimensions explored over months, this headroom keeps things stable as the save file grows.
