How to Allocate More Ram to Minecraft Server 2018

In order to allocate more RAM to your Minecraft server, you’ll need to follow a few simple steps. First, make sure you have the latest version of Java installed on your computer. Next, locate the folder where your Minecraft server files are stored. Look for a file named “” and open it with a text editor.

Within the “” file, you should find a line that says “java -Xmx1G.” This line determines how much RAM is allocated to your server. By default, it is set to 1GB (G stands for gigabytes). To increase this value, simply change the number after “-Xmx” to your desired amount of RAM. For example, if you want to allocate 2GB of RAM, change the line to “java -Xmx2G.”

Why Allocate More RAM to Your Minecraft Server

Benefits of Allocating More RAM to Your Minecraft Server

If you’re an avid Minecraft player or run your own server, you may have encountered performance issues that can hinder your gameplay experience. One way to address this is by allocating more RAM (Random Access Memory) to your Minecraft server. Increasing the amount of RAM available can provide several benefits:

  1. Improved Performance: Allocating more RAM allows your server to handle larger worlds, more players, and complex mods or plugins without lagging or crashing. It helps ensure smoother gameplay and reduces latency issues.
  2. Enhanced World Loading: With additional RAM, Minecraft can load chunks faster, enabling quicker exploration and minimizing those frustrating moments where chunks take time to render.
  3. Reduced Server Downtime: By giving your server extra memory resources, it can better handle sudden spikes in player activity or resource-intensive tasks, reducing the likelihood of crashes or downtime.
  4. Support for Resource-Intensive Mods/Plugins: Many popular mods and plugins require a substantial amount of memory to operate smoothly. Allocating more RAM ensures compatibility with these resource-intensive additions, allowing you to enjoy their features without sacrificing performance.

Understanding The Impact of RAM Allocation on Server Performance

To fully grasp why allocating more RAM is essential for optimizing your Minecraft server’s performance, it’s crucial to understand how it affects overall gameplay. When running a Minecraft server:

  1. RAM Utilization: The game stores various data in its memory while running, including loaded chunks, player inventories, mobs, and redstone circuits. As the number of players increases or complex mods/plugins are added, more memory is needed for efficient processing and storage.
  2. Garbage Collection: Java-based games like Minecraft rely on garbage collection algorithms to free up memory occupied by objects no longer in use. Allowing sufficient allocated RAM minimizes the frequency and duration of garbage collection cycles, reducing performance hiccups and lag spikes.
  3. Player Experience: In multiplayer environments, a slow or unresponsive server can frustrate players, impacting their overall gaming experience. By allocating more RAM, you provide the necessary resources to handle multiple player interactions simultaneously, ensuring smooth gameplay.

Step-by-Step Guide to Increasing RAM For Your Minecraft Server

Now that we understand the importance of allocating more RAM to your Minecraft server, let’s walk through the process step by step:

  1. Check System Requirements: Before increasing your server’s RAM allocation, ensure that your computer meets the recommended system requirements for both Minecraft and any mods/plugins you have installed.
  2. Stop the Server: Safely shut down your Minecraft server before making any changes to its settings. This ensures that no data is lost during the process.
  3. Access Server Configuration: Locate the configuration file for your Minecraft server (usually named “”) and open it using a text editor.
  4. Adjust Memory Allocation: Look for the line that specifies JVM arguments or memory allocation settings (e.g., “-Xmx1G”). Increase this value based on how much additional RAM you want to allocate (e.g., “-Xmx4G” allocates 4 gigabytes of RAM).
  5. Save Changes and Restart: Save the modified configuration file and restart your Minecraft server for the changes to take effect.


Allocating more RAM to your Minecraft server in 2018 can greatly enhance its performance and provide a smoother gaming experience for you and your players. By following the steps outlined in this article, you can ensure that your server has enough memory to handle the demands of the game.

Remember that increasing RAM alone might not solve all performance issues if other factors like CPU power or network bandwidth are limiting factors. Consider optimizing other aspects of your server setup as well.
