How to allocate more ram to minecraft

Points To Remember Before Allocating RAM

First, you might want to understand the RAM recommendations for a Minecraft game.

  • If you have a 32-bit game installed, you can do fine with just 1024 MB (1 GB) RAM.
  • If you have a 64-bit game installed, the minimum requirement is 2GB (2048 MB). For decent gameplay, double it (4 GB or 4096 MB).
  • For the best gaming experience, you can dedicate up to 6 GB of RAM.

To allocate these memory capacities, you need to have sufficient RAM. If you don’t have 2 GB RAM but try to provide the 2GB to the system, it won’t work. It might even overload. You could run into various issues.

As a general rule of thumb, it is better to dedicate a maximum of 50% of your PC’s whole RAM. What does it mean?

  • If you have 4 GB RAM, dedicate up to 2GB to Minecraft.
  • If you have 12 GB RAM, dedicate up to 6 GB to Minecraft.

This rule of thumb works great for almost any kind of game. It won’t hinder your gameplay experience.

Remember that RAM isn’t everything. You will need the best processor and internet connection to play without any problem.
