How to Increase Java Memory on Minecraft

Here is a more in depth guide to increasing memory for java that I have made.

Default Java Memory is around 500MB. Not enough especially for Minecraft
This will increase your FPS aleast 30fps usually. Very useful for those who suffer with poor fps or lag.


FIRST!!! Check How Much RAM You Have:
Click Start and Type System Information. Click on it and it should show you the Available & Physical Memory on your Computer
Once your done go to the first step.

Step One: Open Notepad or Notepad++

Step Two:Type @ECHO OFF

If you have more than 4GB of memory you maybe increase it to your liking.

Step Three Copy the code below and edit to your -Jar "Location of Minecraft.exe" (Example "D:\Minecraft.exe")

Now Check if your typed everything correctly and it looks similar to mine. Example:

Code:

@ECHO OFF "C:\Program Files (x86)\Java\jre6\bin\javaw.exe" -Xmx4g -Xms2g -jar "C:\Users\James\Downloads\minecraft.exe"

Once your done save the file as Minecraft.bat and save to your desktop.

When you launch it should show Command Prompt and Launch Minecraft.
Click Singleplayer and Press F3 to check if it is all right. If yes you have completed the tutorial.

This is all done on Fancy Graphics, Far Rendering and Max FPS Performance Video Settings
