Switch To A Different Minecraft server

RAM is one of the essential parts of operating a server. You won’t use the server without delays if you have adequate RAM.

The first step in setting up a server is deciding on a service plan. You may boost or reduce your RAM whenever you want with Minecraft Server Hosting, and this will guarantee that you obtain the right balance.

The server requires RAM to accommodate all of the connected players and execute all of the software. The number of players on your server and the kind of plugins or modifications installed will have an impact on the amount of RAM required. 

The plans for Minecraft Server Hosting are as follows:

  1. For bare little vanilla servers, 1GB is the recommended plan.
  2. Through 2GB, you may install some essential plugins or modifications and expand your server’s player base.
  3. 3 GB is sufficient for installing medium-sized modpacks or plugin packs, including up to 25 modifications or plugins.
  4. 4GB in most modpacks are included up to 35-40 modifications or plugins.
  5. In 5-10GB, over 40 modifications or plugins are supported.
  6. The 15GB EX Series is designed for huge communities and modpacks/plugins that need a lot of space.
