One of the key aspects of running a server is RAM. If you don’t have enough RAM, you won’t be able to run the server without lags.

With Minecraft Server Hosting, you can upgrade or downgrade your RAM wherever you want to ensure you get the correct balance you need. The first step in creating a server is to know what server plan to choose.

RAM is required by the server to support all of the connected players and run all of the software. The player amount, type of plugins, or mods will affect the amount of ram you will need on your server. That’s why with considerable RAM you can do more with your server.

The Minecraft Server Hosting’s plans are:

  • 1GB – the recommended plan for basic small vanilla servers.
  • 2GB – you can add some base plugins or mods and increase your player base on your server.
  • 3GB – to install medium-sized modpacks or plugin packs – up to 25 mods or plugins.
  • 4GB – includes most modpacks – up to 35-40 mods or plugins
  • 5-10GB – supports over 40 mods or plugins.
  • 15GB EX Series – for very large communities and extreme modpacks/ plugins.

Upgrade or downgrade your plan at anytime by choosing one of the most secured server hosting.
