Hello. This guide teaches you how to Allocate more Ram for your Minecraft client.

Please note: This guide doesn't tell how to allocate more Ram for your server.

[This is for Windows users]


Step 1:

Make sure you have 64bit Java. You can get it from here:

Step 2:

Once you have installed 64bit java succesfully, make new Text Document

Step 3:

Open the Text Document. Below you can choose the ram amount you want to allocate for your client.

[NOTE] Make sure you have Minecraft.exe on your Desktop!

[NOTE] Do not allocate more ram than you have!

Click to Open

Allocate 2GB:
java -Xmx2048M -Xms1024M -jar "C:/Users/YOURUSERNAME/Desktop/Minecraft.exe"
Allocate 3GB:
java -Xmx3072M -Xms2048M -jar "C:/Users/YOURUSERNAME/Desktop/Minecraft.exe"
Allocate 4GB:
java -Xmx4096M -Xms3072M -jar "C:/Users/YOURUSERNAME/Desktop/Minecraft.exe"
Allocate 5GB:
java -Xmx5120M -Xms4096M -jar "C:/Users/YOURUSERNAME/Desktop/Minecraft.exe"
Allocate 6GB:
java -Xmx6144M -Xms5120M -jar "C:/Users/YOURUSERNAME/Desktop/Minecraft.exe"
Allocate 7GB:
java -Xmx7168M -Xms6144M -jar "C:/Users/YOURUSERNAME/Desktop/Minecraft.exe"
Allocate 8GB:
java -Xmx8192M -Xms7168M -jar "C:/Users/YOURUSERNAME/Desktop/Minecraft.exe"

Step 4:

Once you have chosen one of them for you, copy and paste it to the text document, click save. After you saved it, close the text document, and rename it as Minecraft.bat

Run the Minecraft.bat and your minecraft should open.

Well Done!

[NOTE] Always mind to run your Minecraft by the Bat file.

[NOTE] Dont close the Black box (CMD)

You must know the amount of RAM you have own your Laptop/Desktop.
For Example, if you have 6GB Of Ram on your Computer, i would allocate 2-3 or 3-4GB For Minecraft.
