Are you wanting to play a mode in Minecraft but experiencing a lack of RAM? Or you might experience slowness while playing. Although Minecraft requires no big memory size unlike other recent games, you still need the right memory size for optimal gameplay experience. This post explains how to allocate more RAM to Minecraft and how much memory is required to play the game in a different environment. Plus, you will gain extra knowledge about playing Minecraft.

Minecraft Hardware Requirements

To understand how much more you need to allocate RAM, we first need to know the hardware requirements for Minecraft. As you could guess from the graphic, the game does not require huge RAM or expensive graphic cards. The minimum and recommended requirements are different from the environment you play.

Minimum Requirements for Java Edition

  • CPU: Intel Core i3-3210 3.2 GHz / AMD A8-7600 APU 3.1 GHz or equivalent
  • RAM: 2 GB
  • OS: Windows 7 and above (Minecraft: Java Edition)
  • Video Card: Integrated: Intel HD Graphics 4000 (Ivy Bridge) or AMD Radeon R5 series (Kaveri line) with OpenGL 4.41Discrete: Nvidia GeForce 400 Series or AMD Radeon HD 7000 series with OpenGL 4.4
  • Free Disk Space: 1 GB or above

Recommended Requirements for Java Edition

  • CPU: Intel Core i5-4690 3.5GHz / AMD A10-7800 APU 3.5 GHz or equivalent
  • RAM: 4 GB
  • OS: Windows 10
  • Video Card: GeForce 700 Series or AMD Radeon Rx 200 Series (excluding integrated chipsets) with OpenGL 4.5
  • Free Disk Space: 4 GB
  • Dedicated Graphic Memory: 256 MB

Minimum Requirements for Windows 10

OS: Windows 10 version 17134.0 or higher
CPU: Intel Celeron J4105 | AMD FX-4100
VIDEO CARD: Intel HD Graphics 4000 | AMD Radeon R5
DIRECTX: DirectX12FL11

Recommended Requirements for Windows 10

OS: Windows 10 version 17134.0 or higher
CPU: Intel i7-6500U | AMD A8-6600K
GPU: NVIDIA GeForce 940M | AMD Radeon HD 8570D

Depending on your environment, you can start Minecraft with the RAM size as small as 2GB. To have an optimal experience on Windows 10, you need 8GB RAM.

Check your RAM

We learned the RAM requirements for Minecraft. Next question you will ask would be how we can check RAM size of our laptop. If your OS is Windows 10, it is easy. Click Start menu and type “about”. Find “About Your PC” and hit enter. As you scroll down, you will see Device Specifications. Under the section, check “Installed RAM”. If it is MAC, find the apple menu at the top left corner and select “About This Mac”. On the popup window, check the Memory section.

Knowing your RAM and minimum and recommended requirements, you will know how much you want to increase your RAM now. Let’s find out how to allocate more RAM.

How to Allocate RAM to Minecraft

There are three ways to allocate more RAM to Minecraft.

Use a Minecraft Server

If you are unfamiliar with computers, this might be a little tricky. First, read through steps here. If you find it difficult, asking for help to someone who might know can be a good idea.

  1. To make sure, update your Java version to the latest. Visit and click “Download” below the latest Java version. This is a prerequisite before RAM allocation. If your OS is Windows, make sure you choose the right bit – 32 or 64. You can only allocate 1GB RAM on a 32-bit PC. To check your bit, check this guide from Microsoft.
  2. Go to the file directory that has Minecraft_server.exe. This file is what you use to launch your Minecraft server. The easiest way to find the folder is by searching for the “Minecraft_server” file and then opening its file location.
  3. In the server folder, create a text (txt) document. Right click and find a file creating menu. Make sure you create a new file in the same folder where minecraft_server.exe file is located.
  4. Copy and paste the code below to allocate more RAM. Find the right one depending on your OS.


 java -Xmx####M -Xms####M -exe Minecraft_Server.exe -o true


 cd "$( dirname "$0" )"
 java -Xms####M -Xmx####M -exe Minecraft_Server.exe -o true
  1. Find #### and change it to a figure in megabytes you want to allocate. If you want to allocate 4GB, that will be 4096. If it’s 2GB, that will be 2048.
  2. Save the file. If your OS is Windows, save the file as Minecraft_Server.bat. If you use Mac, save it as Minecraft_Server.command.
  3. Execute the new file to start Minecraft. This new file will be your new launcher for the Minecraft server. By running this file, you can allocate more RAM to Minecraft.

Use Minecraft Launcher

Minecraft comes with its default launcher, and you can use to allocate more RAM. Follow the steps below.

  1. Find and open the Minecraft launcher and select the version you want to play (Bedrock or Java).
  2. Choose the installations from the tabs to find a list of releases. If you haven’t set up any specific versions, you might be able to see the latest version only.
  3. Hover your cursor over the version and click the three dots on the right. Click Edit.
  4. Then, you will be able to see a screen with the installation name, the version, and a some other settings. Select More Options and scroll down until you can see JVM Arguments. Don’t be panic when you find lots of code. You only need to change the first part of it that looks like:
  1. In Xmx2G, 2G means the amount of RAM you want to allocate. Try to change that “2G” to the size you want to allocate like “4G” for example. When you do that, mind the total RAM size your desktop or laptop has.
  2. After making that change, click Save and launch Minecraft!

It could be not easy to change the RAM size on your own if you are not familiar with computer. This video guide can be easier to follow than the written guides.

We learned how to allocate more RAM to Minecraft. You’ll need to know the RAM size you have in your computer and allocate a proper size of RAM. If written guides are difficult, try the video instructions. If you don’t have enough memory size, you might want to upgrade a RAM or buy a new laptop. Considering Minecraft does not require heavy RAM size to start with, if you cannot even start Minecraft, purchasing a new laptop can be a good idea.
