Question 1

How much RAM does a Satisfactory server need?

Accepted Answer

It depends almost entirely on your save, not your player count. A fresh world runs happily on 4GB, mid-game factories suit 6GB, and late-game saves with large conveyor, train, and drone networks typically sit at 8-12GB. Enormous long-running megafactories can justify 16GB. If you're unsure, start at 4GB and resize as the factory grows - upgrades are instant and keep your save.

Question 2

Why does my Satisfactory server keep using more RAM?

Accepted Answer

Because the factory must grow. Every machine, conveyor, item in transit, train, and vehicle is simulated by the server whether or not anyone is nearby, so memory use scales with everything you've ever built. That's normal Satisfactory behaviour, not a leak - though the dedicated server has historically had genuine memory quirks too, which regular restarts (schedulable from the panel) keep in check.

Question 3

How many players can join a Satisfactory server?

Accepted Answer

The game is designed and tuned for up to 4 players, and that's where it plays best. The cap can be raised via server config, and groups do run 6-8, but Coffee Stain doesn't officially support it and desyncs become more likely as both the population and the factory grow. If you raise the cap, use 12GB or more.

Question 4

Are Satisfactory dedicated servers stable?

Accepted Answer

Mostly, with honest caveats. Dedicated servers spent years marked experimental and still carry rough edges: occasional crashes, memory growth over long uptimes, and short breakages after game updates until the server build catches up. Automatic backups, scheduled restarts, and auto-updates blunt all three - but if you're expecting the polish of the client game, it isn't quite there yet.

Question 5

Can I upload my existing Satisfactory save?

Accepted Answer

Yes. Satisfactory has a built-in server manager in the game client that can upload your single-player or co-op save directly to the server, or you can transfer the save file via FTP. Downloads work the same way, so you can pull the server save back to single-player whenever you like.

Question 6

Do mods work on Satisfactory dedicated servers?

Accepted Answer

Many do. Mods from ficsit.app (the Satisfactory Mod Repository) increasingly support dedicated servers, and the Satisfactory Mod Manager can target a server installation. Each mod declares its own compatibility though, and both server and every client need matching mod sets - so check your list before committing a 200-hour save to it.

Question 7

Will my renewal price go up?

Accepted Answer

No. Satisfactory servers are priced at a flat £2.50 per GB of RAM per month, and the renewal price is identical to the intro price - a £10/month 4GB server renews at £10/month for as long as you keep it.
