How much ram do I need for my Minecraft server?

Minecraft servers require varying amounts of RAM depending on their purpose and configuration. RAM is the server’s memory, determining the number of tasks it can handle simultaneously.

If a Minecraft server doesn’t have enough RAM, it may experience performance issues, so it’s essential to understand what influences RAM usage and how much is needed.

Generally, the more addons (mods/plugins) and players a server supports, the more RAM it will require.

Vanilla - Spigot - Paper Vanilla servers generally require less RAM than other server types, but several factors can influence the exact amount needed.

Minecraft 1.16.5 and previous	2GB
Minecraft 1.17+	3GB
For every additional 5 players	+1GB
For every 10 plugins	1+GB (can be dependent on how ram dependent the plugin is)

Forge / Fabric

Running a modded Minecraft server can greatly increase your RAM usage, often much more than a vanilla server. The required RAM varies based on several factors:

• Number of Mods: More mods generally mean more RAM is needed. Each mod requires memory to load assets, handle processes, and interact with other mods.

• Minecraft Version: Newer versions of Minecraft tend to use more resources due to added features and optimizations.

• Number of Players: With more players online, the server has to manage more actions and entities, which increases RAM demand.

• Server Progress: As players explore, build, and interact with the world, more chunks load, and entities spawn, both of which consume more memory over time.

Allocating enough RAM to handle your modpack’s needs is essential for maintaining a smooth and enjoyable experience on your server.

Minecraft 1.12.2 and previous modpacks	4GB
Minecraft 1.13-1.16.5 Modpacks	5GB
Minecraft 1.17+ Modpacks	6GB

It’s essential to check the recommended RAM usage on the official webpage of many modpacks, as they often provide guidance on optimal performance.
