The Windows operating system independently disposes of the RAM installed on the computer to launch various processes. But often, some programs do not get enough resources - especially for some Java games. For example, the game Minecraft is very demanding on the computer hardware. To allocate more memory, you need to make some adjustments.
Instructions
Step 1
To allocate more memory for Java applications, you can edit some parameters of the Java machine installed on your computer. Go to Start Menu - Control Panel - Programs. From the list of sections that appears, select Java.
Step 2
In the settings window that opens, select the line Java - View. Specify -Xincgc -Xmx768M in the Runtime. Parameters line. If you have a 64-bit operating system, enter the amount of memory you want to allocate for the application as you like. For example, in the settings line, enter -Xincgc -Xmx2048M. This gives the Java virtual machine 2048 MB of RAM to use.
Step 3
After specifying the required data, click the "OK" button and restart the computer to apply the changed settings. After rebooting, you can launch the application you want.
Step 4
It is also possible to write the memory allocation parameters for the Java machine using computer environment variables. Click on the "Control Panel" item in the "Start" menu. Then click on the link "System settings" - "System". In the section that appears, specify "Advanced" - "Environment Variables". Click on the "Create" button.
Step 5
In the Name section, enter _JAVA_OPTIONS. Then set the parameters you need to change - enter the configuration -Xincgc -Xmx3G. It should be noted that in this case, 3G means a memory allocation of 3 Gigabytes.
Step 6
Minecraft has become one of the most demanding Java games. In her profile settings, you can manually specify the amount of RAM you want to allocate. Click on the Edit Profile section in the game launcher window and write the amount of RAM in the appropriate paragraph. Then save your changes. Now you can start launching the game.
