Determining the right amount of RAM for your Minecraft server is crucial for optimal performance. RAM requirements vary based on the server's purpose, configuration, number of players, and additional addons like mods and plugins.

Understanding RAM in Minecraft Servers

RAM (Random Access Memory) is essential for your server's performance. It dictates how many tasks your server can handle simultaneously. Insufficient RAM leads to performance issues, so it's vital to allocate the right amount.

RAM Requirements for Different Server Types

Vanilla / Spigot / Paper Servers

  • Vanilla servers typically need less RAM, but requirements can vary based on versions and server activity.

  • Minecraft 1.16.5 and previous versions: 2GB RAM

  • Minecraft 1.17 and newer: 3GB RAM

  • Additional RAM for players and plugins: +1GB for every 5 players or 10 plugins

BungeeCord Servers

  • BungeeCord servers generally have low RAM requirements, but this can increase with more plugins.

  • 0-5 BungeeCord Plugins: 1GB RAM

  • 6-15 BungeeCord Plugins: 2GB RAM

  • 16+ BungeeCord Plugins: 3GB RAM

Forge / Fabric Servers

  • Modded servers require significantly more RAM due to the additional resources mods consume.

  • Minecraft 1.12.2 and previous modpacks: 4GB RAM

  • Minecraft 1.13-1.16.5 Modpacks: 5GB RAM

  • Minecraft 1.17 and newer Modpacks: 6GB RAM


Choosing the right amount of RAM for your Minecraft server is a balance between the server type, number of players, and addons. By following these guidelines, you can ensure smooth gameplay and server stability.
