Valheim Server RAM Calculator

Valheim is relatively lightweight compared to games like ARK or Rust. A vanilla server for a small group needs 2-3GB of RAM. With mods and more exploration, 4-6GB is typically enough. Valheim's world data grows as players explore, so RAM usage increases gradually over time.

For a vanilla Valheim server, 2GB of RAM is sufficient for 1-4 players with modest exploration. For a full 10-player server, 3-4GB is recommended. If your group explores aggressively and builds large bases, consider 4GB to ensure smooth performance.

Modded Valheim servers using Valheim Plus or BepInEx mods require more RAM. A light mod setup (1-10 mods, including Valheim Plus) adds about 0.5-1GB overhead. Medium setups (10-25 mods) add 1-2GB. Heavily modded servers with 25+ mods or overhaul packs should have 2-3GB extra, bringing the total to 5-6GB or more.

Yes! With DoomHosting, you can upgrade or downgrade your RAM at any time through your control panel. Changes take effect immediately, so you can start with a smaller plan and upgrade as your Viking crew grows or your world expands.

Valheim generates its world procedurally, and terrain data is stored in memory as players explore. A newly created world uses relatively little RAM, but as players discover new biomes and the map grows, memory usage increases. A fully explored world can use 1-2GB more than a fresh one. Building large structures also contributes to memory usage, as each piece is tracked by the server.
