Valheim: Dedicated Server Requirements
Running a smooth Valheim server depends on balanced hardware. While the game isn't heavily CPU-intensive, it is sensitive to network latency and single-core performance. This guide outlines the necessary specs for a lag-free experience.
Hardware Specifications
| Component | Recommended Requirement |
|---|---|
| CPU | 4 Cores (High clock speed preferred over core count) |
| Memory (RAM) | 4GB for 2-10 players. 8GB+ for heavily modded servers. |
| Storage | 10GB Free SSD space (plus additional for world backups). |
| Bandwidth | 100 Mbps Up/Down minimum. |
Optimizing Server Performance
1. Combatting Desync
Valheim uses a unique networking model where one player acts as the "owner" of an area. If that player has a poor connection, everyone nearby will experience lag.
Solution: Install the Better Networking mod. It increases the data rate limit from the default 64kb/s to a much more modern 256kb/s+.
2. Memory & Item Cleanup
Over time, dropped items (drops) can accumulate and slow down world-save times.
- Use the admin command
removedropsregularly. - Be warned: this deletes ALL items on the ground globally. Ensure players are not in the middle of a move!
3. Server Location
Latency (Ping) is the #1 enemy of Valheim combat. Always host your server in a region closest to the majority of your players. Routing issues across oceans will cause "ghost hits" where enemies strike you before their animation finishes. If you would rather not benchmark single-core clock speeds and tune networking yourself, a managed Valheim dedicated server ships with high-clock X3D cores and a region picker that handles the latency math for you.
Pro Tip: Valheim servers use ports 2456-2458 (UDP) by default. Ensure these are open in your firewall or NAT settings.
