This is how you can allocate more RAM in Minecraft on PC and for those who run Minecraft on the server
Minecraft is one of the most popular games of this generation, and is available for almost all platforms, from PC to Mac and even iOS and Android. This works very well on most devices, but it can always be better – especially if you have a PC with lots of RAM to utilize.
Although it used to be rather complicated to allocate more RAM in Minecraft, the third-party ATLauncher release changed all that. Here’s how to allocate more RAM in Minecraft on the PC, and for those who run Minecraft on the server too.

How to allocate more RAM in Minecraft
Although it was once a complex task to manually allocate more RAM in Minecraft, there is now a useful mod that removes all tweaking of code manually. Here’s how:
- Make sure you have the latest version of Minecraft installed.
- Check your computer’s total RAM by going to Start> Settings> System> About.
- Download and install ATLauncher.
- Open the ATLauncher application.
- On the right side of the launcher, select Settings.
- Select the Java / Minecraft tab.
- Enter the amount of RAM you want to use (in MB, not GB) in the Maximum RAM Memory field, or use the arrows to adjust the value to 0.5 GB at a time.
- Click Save.
And there he is! The next time you load Minecraft, it will use a certain amount of RAM that you have allocated.
How to allocate more RAM on the Minecraft Server
The process to adjust the amount of Minecraft RAM usage when hosted on a server is slightly different, because it is not included in ATLauncher. It’s not too complicated:
- Open your Minecraft server directory (the folder containing the Minecraft_server.exe file where you launched the Minecraft server). If you are an element of location, search for “Minecraft_server” on your PC.
- Click Home> New Item> Text Document on PC to create a text document in the server directory.
- In a new text document, paste the following (if on a PC):
java -Xmx #### M -Xms #### M -exe Minecraft_Server.exe -o true
- Replace #### with the value, in MB, that you want to allocate (1GB = 1024MB). For example, if you want to allocate 2GB of RAM, I enter 2048.
- Click File> Save As … and change Save as type to All Files. Name the file server launcher and change the extension from .txt to .bat.
- The file you created will now be the new launcher for your Minecraft server – just double click to run it. Using the .bat file to launch the server will automatically allocate the amount of RAM specified.
