Game server RAM calculator
How much memory your server needs, from the game, your group size and your mods, with what that size costs.
Checked against Pocketpair's and the Satisfactory wiki's published figures, and the lowest size each game booted at in our own tests on . Sources: Palworld docs: requirements and Satisfactory wiki: dedicated servers.
Reference
RAM by game, at a typical group size
The estimate is memory for the server and world, plus a share for each player online and each mod, rounded up to the next size a server comes in. Where a game's makers publish a figure, it is shown beside ours with a link.

Questions
Questions and answers.
- How much RAM does a Palworld server need?
- Pocketpair's own requirements page lists 16 GB, with the line "Recommended for larger than 32GB". It says 8 GB boots, but makes out-of-memory crashes more likely.
- How much RAM does a Satisfactory server need?
- The Satisfactory wiki gives 8 GB, and says 16 GB may be recommended for larger saves or more than four players. Late-game factories are the heavy case.
- Where do the other numbers come from?
- From us. For Minecraft, Valheim, Project Zomboid and 7 Days to Die the calculator gives our own estimate, and the table shows the lowest size each game booted at in our tests. Both are labelled as ours.
- Why is the recommended size bigger than the estimate?
- The estimate is rounded up to the next size a server comes in, and never goes below the lowest size the game booted at in our tests.
