As one of the popular games since its release, Minecraft may look fun and simple. But don’t be mistaken, because this Sandbox game is actually pretty intensive. 

Therefore if there’s a delay during your Minecraft playing and/or your computer is crashing on full force, it could be because your installed RAM is insufficient for playing the game. 

You have two options for dealing with this type of issue: downgrade your game or upgrade your allocated RAM in your Minecraft game. Unsurprisingly the latter option is much more popular among Minecraft players. 

So, if you want to know how to allocate more RAM to Minecraft, keep reading because we’ll go over this in greater detail.

What Is RAM Allocation, and Why Does It Matter in Playing Minecraft? 

Random Access Memory (RAM) is the main memory in a computer that focused on the current used programs and data. 

Whereas according to Techopedia, RAM or Memory allocation is the process of putting aside a fragmented or an entire portion of computer memory for the execution of programs and processes. 

By allocating more RAM to Minecraft, it will increase the game performance thus, ensuring your Minecraft gaming experience is a smooth sailing journey without any lagging, limitation, or constant crashes that frustrates you. 

Things to Note Before You allocate More  RAM to Minecraft 

Before proceeding to the method of how to allocate more RAM to Minecraft, you need to note down a few things below: 

[This is because Minecraft: Bedrock Edition will automatically allocate RAM according to your game requirements and there’s no built-in option to control or change RAM allocation. ]

  • You need to know how much your installed RAM in your computer is before allocating them to Minecraft. 

[Because it’s definitely out of question to tell your device to allocate 10GB towards Minecraft when in total you only have 8GB  installed on your computer.]

How to Allocate More RAM to Minecraft

However, there is more than 1 launcher in Minecraft as mentioned below: 

  1. Default Launcher 
  2. AT Launcher 
  3. Void Launcher

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

Replace #### with the RAM value that you want to allocate. 

Note: Please keep in mind that the value must be in MB (Megabytes). As 1GB = 1024MB, you must multiply the number of GB (Gigabytes) you want to allocate by 1024MB.
