Our RAM sizes are a guide, based on player count. What a server really uses also depends on its mods and plugins, its settings (map size, view distance and spawn rates all count), how much its world grows over time, and the game's own updates. If you're planning a modded server, start a size up.
Quick start

We recommend
Up to 12 GB RAM

How much RAM
each game gets.
We size servers by how many people play, because that's the number you know before you buy. Here's the RAM each game's server can use, up to, for each size of group.
| Game | Up to 10 players | Up to 25 players | 50+ players |
|---|---|---|---|
| Rust | 12 GB | 12 GB | 16 GB |
| Minecraft | 2 GB | 4 GB | 8 GB |
| ARK: Survival Evolved | 10 GB | 10 GB | 12 GB |
| Palworld | 10 GB | 12 GB | 16 GB |
| Valheim | 10 GB | 10 GB | 10 GB |
| 7 Days to Die | 10 GB | 10 GB | 12 GB |
| Enshrouded | 8 GB | 8 GB | 12 GB |
| Satisfactory | 8 GB | 16 GB | 24 GB |
| V Rising | 10 GB | 10 GB | 12 GB |
These sizes are a guide. Mods, game settings and updates can all change how much RAM a server needs. The quick start gives you a starting size from your game and player count.

Planning mods? Go a size up
Mods, plugins and modpacks load into memory alongside the game, so a modded server needs more than a vanilla one with the same players.

Each game's page shows its plans with that size picked out, ready to order.

FAQ
Questions,

What people ask about this.
Is the recommended size guaranteed to be enough?
Our RAM sizes are a guide, based on player count. What a server really uses also depends on its mods and plugins, its settings (map size, view distance and spawn rates all count), how much its world grows over time, and the game's own updates. If you're planning a modded server, start a size up.
Why does the size go up with players?
More players means more of the world loaded at once and more going on in it, and all of that sits in memory.
What makes a server need more than the guide?
Mods and plugins, big maps and worlds that keep growing, and the game's own settings. That's why the sizes are a starting point.
