RAM guides for each game

What fills a server's memory in each game, and the sizing mistake that game's players make most.

Common questions

Why is Palworld so memory-hungry?

It runs on Unreal Engine 5 and keeps a lot in memory for Pal AI pathing and bases, and its usage also creeps up the longer the server runs. Start from 8GB at the very least; groups with many bases are safer on 12GB+.

How much do mods add to a Minecraft server?

A lot. Unmodded Minecraft is comfortable on 2-3GB of RAM for a small group, but big packs such as All The Mods or Better MC load thousands of extra assets and scripts at startup and need 8GB+ before anyone can even join.

What happens when a server runs out of RAM?

The operating system steps in with an OOM (Out of Memory) kill. The server process dies on the spot without saving, and everyone connected is dropped.

Can I add RAM later if I guessed wrong?

On most managed hosts, yes. On Spawnly, for example, you change the server's RAM from its control panel in either direction, and your files and IP address stay the same. On your own hardware it means a new machine or new memory sticks.

Rather not run the server yourself?

These tools are free and funded by the two hosting services we run. If you want a server that is already set up, here they are.
