  • To edit JVM arguments, click More Options from the Edit Installation Menu.
  • Select the text highlighted in yellow above in the JVM argument. This is the text which allocates RAM for your Minecraft client. This section contains only one number, which most likely has a default value either 1 or 2.
  • This section should be changed to indicate how many gigabytes (GBs) of RAM Minecraft would like to use. If you wish to use 4 GB RAM, the text in this section should read -Xmx4G.
  • Make sure you have not edited any other part of the JVM Arguments text. You can cancel any edited text and begin over.
  • Click on Save in the bottom right corner.
  • Once you’ve completed the above steps, Minecraft will now run with the additional RAM that you have been given. Play the original version you have edited and not another installation profile.
