How much RAM for a Valheim server?
A Valheim server runs on 4 GB of RAM with up to about ten players on a young world. Plan on 8 GB once the world has been widely explored and built, and 12 GB for a modded server or a large community. Valheim has a particularity: the world is not loaded whole, but every discovered zone is kept and reloaded when a player comes near.
| Type of server | Players | Recommended RAM | Matching plan |
|---|---|---|---|
| Young world, among friends | 2 to 10 players | 4 GB | £4.14incl. VAT/mo |
| Explored world, several bases | 10 to 20 players | 8 GB | £8.29incl. VAT/mo |
| Modded server (Valheim Plus, BepInEx) | 20 players and up | 12 GB | £12.44incl. VAT/mo |
| Permanent community, old world | no limit | Unlimited | £20.74incl. VAT/mo |
What drives memory up
- How much of the world has been discovered: every visited zone is stored for good.
- Buildings, especially large bases with many individual pieces.
- Portals and distant bases, which keep several zones active at once.
- Mods, particularly those adding buildings or creatures.
Signs you are short on memory
- Portal travel taking several seconds longer than before.
- Boats or items disappearing in distant areas.
- The world taking longer and longer to save, with a visible freeze.
- Disconnections when several players explore opposite regions at once.
Frequently asked questions
Why does my Valheim server grow over time?
Because Valheim permanently records every visited zone, along with its buildings and dropped items. A heavily explored world therefore takes more memory than a new one, even with the same number of players. Clearing out abandoned bases genuinely helps.
Do mods change consumption much?
Yes. BepInEx and building mods add objects and recipes that stay loaded. A modded server generally needs one memory tier above its vanilla equivalent.
Do I need a dedicated server to play with a few friends?
Not necessarily, but hosting from the game means the host must be online and their machine must carry the load. A dedicated server stays up permanently and keeps progress reachable for everyone, even when nobody is around to host.
Each memory tier matches a plan. Prices are monthly, tax included, with no minimum term. See the plans Valheim →
