How Much RAM Does The Ocean of Subnautica Server Need?

The Ocean of Subnautica packs a lot into a single Forge 1.20.1 world — custom ocean generation, submersible crafting, and deep-sea exploration mods that add up fast. Check the The Ocean of Subnautica pack page for the full mod list before picking a tier below. 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

The bare minimum for solo or duo play. Expect noticeably slower chunk loading as the custom ocean terrain generates outward, with little headroom left over for extra sea-life mobs or a second submersible in use.

5 GB

The best starting point for most servers. Covers the custom ocean generation, submersible mechanics, and alien sea life mods that define The Ocean of Subnautica, with enough room for a small group playing together.

8 GB

A safer choice for a mid-size active group running several underwater bases and submersibles at once, especially once people start pushing into deeper, more detailed trench biomes.

12 GB

Built for 10+ players and a long-running world — multiple base clusters, heavier submersible traffic, and the sustained mob and chunk load that comes with a mature deep-sea save.
