How to Allocate more Ram to Minecraft

Step-by-Step Guide: Allocating More RAM to Minecraft for Improved Performance

Minecraft, the beloved sandbox game, can sometimes run into performance issues, especially when dealing with large mod packs or resource-intensive worlds. Allocating more RAM to Minecraft can significantly improve its performance and reduce lag. In this blog post, we will guide you through the process of allocating more RAM to Minecraft on Windows, macOS, and Linux systems.

  1. Check System Requirements: Before proceeding with allocating more RAM to Minecraft, ensure that your system meets the game’s minimum requirements. Additionally, verify that you have sufficient physical RAM available for allocation.
  2. Back Up Your Minecraft Data: To avoid any potential issues during the process, it’s always wise to create a backup of your Minecraft data. Copy the entire “.minecraft” folder to a safe location, which includes your worlds, mods, and other important files.
  3. Launch Minecraft with More RAM on Windows:
  • Locate the Minecraft launcher executable (minecraft.exe) or shortcut.
  • Right-click on it and select “Create shortcut.”
  • Right-click on the newly created shortcut and choose “Properties.”
  • In the “Target” field, you’ll see something like this: “C:\Path\To\Minecraft.exe”. Add the following text at the end: ” -Xmx4G”. Here, “4G” represents the amount of RAM you want to allocate (e.g., 4GB).
  • Click “Apply” and then “OK.”
  • Double-click the modified shortcut to launch Minecraft with the specified RAM allocation.
  1. Allocate More RAM to Minecraft on macOS:
  • Open the Terminal app (Applications > Utilities > Terminal).
  • Type the following command and press Enter: “cd ~/Library/Application\ Support/minecraft”
  • Now, execute this command to edit the launcher settings: “nano launcher_profiles.json”
  • Look for the “arguments” section and find the line starting with “javaArgs.” Add “-Xmx4G” (or your desired RAM allocation) after “javaArgs”: [“-Xmx4G”, “-XX:+UnlockExperimentalVMOptions”, …]
  • Press Ctrl + X, then Y, and Enter to save the changes.
  • Launch Minecraft to use the newly allocated RAM.
  1. Allocating More RAM to Minecraft on Linux:
  • Open the Terminal.
  • Navigate to the Minecraft installation directory by using the “cd” command.
  • Edit the launcher_profiles.json file using a text editor like nano or gedit.
  • Find the “arguments” section and add “-Xmx4G” (or your preferred RAM allocation) after “javaArgs”: [“-Xmx4G”, “-XX:+UnlockExperimentalVMOptions”, …]
  • Save the changes and exit the text editor.
  • Launch Minecraft to enjoy the benefits of increased RAM allocation.


By following this step-by-step guide, you can allocate more RAM to Minecraft and potentially witness a noticeable improvement in performance. Keep in mind that allocating excessive RAM can impact system stability, so it’s essential to find the right balance. Monitor your system’s performance while gaming, and adjust the allocated RAM as needed. With a smoother Minecraft experience, you can fully immerse yourself in the infinite possibilities of this extraordinary world-building game. Happy crafting!
