How much RAM does my game server need?

A simple guide to choosing the right memory for Hytale, Project Zomboid and Valheim servers, based on players and mods.

Memory (RAM) is the main thing you choose when you rent a game server. Too little and the server lags or crashes. Too much and you’re paying for nothing. Three things decide how much you need:

  • Players online at the same time, not total members
  • Mods and plugins, often the biggest factor
  • World size, since more of the map explored means more to keep in memory

Quick guide

GameSmall groupMediumLarge or heavily modded
Hytale4 GB (up to ~5)8 GB (10–20)12–16 GB
Project Zomboid4–6 GB (up to ~8)8 GB (up to 16 + mods)12–16 GB
Valheim3 GB (up to 4)4 GB (up to 10)6–8 GB with mods

These are starting points from typical servers. Every world and mod list is different.

Signs you need more

  • Memory use in the dashboard regularly sits above 85–90%
  • The server crashes with “out of memory” errors in the console
  • Lag spikes when players explore new areas

Upgrading is easy

You can move up a plan at any time and only pay the difference for the rest of the month. Your world, mods and settings stay exactly as they are. Not sure? Each game page has a plan finder, or ask us on Discord.
