How it works

What Actually Uses RAM on a Valheim Server

Building is what makes Valheim heavy. Every placed piece is saved and simulated while players are near it, so a sprawling village costs far more than a camp.

The more of the world your group has explored, the bigger the save the server keeps loaded. BepInEx mods add on top, and players spread out load more of the world at once.

The calculator adds those up from data we collected on Valheim servers, then leaves about 15% headroom so the server never runs right at its limit. It's a guide, not a promise, and you can upgrade from the client area at any time.

Frequently Asked Questions

Quick answers about Valheim server memory.

How much RAM does a Valheim server need?

4 GB is enough for a small group starting out. An established world with villages wants 8 GB, and mega builds or modded servers need 12 GB.

Why does my Valheim server get slower as we build?

Every placed piece is part of the world the server simulates around players, so big bases add memory and CPU load.

How many players can join a Valheim server?

Vanilla Valheim allows 10 players per world. Server mods can raise that, and FangHosting does not cap slots.

Is the calculator exact?

It is an estimate based on data we collected, with headroom added. You can upgrade from the client area at any time.
