How Much RAM Does a Keo Optimized Server Need? (4GB+ Guide)
Keo Optimized needs far less RAM than a typical modpack guide suggests — see the Keo Optimized pack page for the full mod list, but the short version is that it adds performance mods, not content, so the usual kitchen-sink RAM math doesn't apply here. Finnish players: Minecraft-palvelin hosting is our native-language page. German players: Minecraft-Server mieten covers the same hosting auf Deutsch. Svenska spelare: Hyra Minecraft-server täcker samma hosting på svenska.
2 GB
Works for solo play or a very small test, close to what vanilla Minecraft needs on its own — this pack doesn't add the kind of content that pushes RAM needs up the way a real modpack does.
4 GB
The recommended floor and the best starting point for most groups — comfortable headroom for several players exploring together on a pack that's essentially vanilla with performance mods layered in.
6 GB
A safer pick for a more active public-feeling server with more simultaneous players, mostly to leave room for plugins, extra players, or a bit of world exploration headroom rather than the pack itself.
8 GB
More than this pack typically needs even for a larger group — worth it only if you're planning to layer on extra plugins or datapacks beyond what Keo Optimized itself ships with.
