Template:RAMFix

In some rare cases, a setting in windows may cause a maximum RAM limit that Minecraft can't override. This will give you instructions on how to fix this.

''This tutorial is designed for windows 10, but the process should be fairly similar, if not identical, on windows 7 and 8. You will need administrator permissions to complete this tutorial.''

Start by navigating to the environment variables. You can find them like so: Control Panel -> System and Security -> System -> Advanced System Settings -> Environment Variables.

Here you should see two boxes of variables for various programs, the top box is for user specific variables and the bottom for system-wide variables. Look for a variable related to java. Click on it and click edit. Remove the -Xmx that you should find in the edit box (If that's the only thing in the edit box, then just delete the variable entirely.). Then click Ok to save it.
