How to allocate more RAM to Minecraft in 4 easy ways?

When it comes to Minecraft, you can never get enough of it. After all, there are not many open-ended sandbox games where you can explore infinite worlds with online communities and build anything to your heart’s content. However, despite its simplistic gameplay, Minecraft is a heavy application, especially if you’ve added various plugins and texture packs to beautify its graphics.


You see, the bigger and more detailed your Minecraft world gets, the more Memory (RAM) needs to be allocated to it. This article will tell you when it is time for you to allocate more RAM to Minecraft and how to do so with easy and efficient steps. 

What are the signs that you need to allocate more RAM?

Well, one of the most common signs that will tell you it’s time to allocate more RAM to your Minecraft is when your client keeps crashing continuously

It will either crash when you try to connect to the Minecraft server, or it may not start at all! This error is more pronounced in a heavily modded Minecraft game. 

If you want to experience more intensive gameplay and enhanced graphic settings, you will have to add a few mods/plugins. This automatically means that more RAM will have to be allocated to Minecraft. Otherwise, your frames will stutter, the game will load slowly, etc. 

For the modded version of Minecraft, you require at least 4 Gigabytes of Memory or even 6 GB, whereas the vanilla gameplay version only requires a minimum of 2GB.

How to allocate more RAM to Minecraft?

There are several ways to allocate more RAM to Minecraft using different launchers. Every launcher provides a different gameplay experience thus, making it unique in its way. The following methods are based on the most popular launchers.

How to free up RAM on your PC?

Here are a few tips and tricks which will help you with memory allocation in the most efficient way possible. They will help you make the most of your RAM allocation without having to delete apps and programs unnecessarily.

1. Restart your PC.

This helps you get a clean slate in the sense that your programs will be rebooted, all the processes running in the background will be cleared out, and your RAM will be wiped clean. 

2. Getting your software updated.

3. Clear out your cookies and cache. 

4. Disable browser extensions.

5. Stop running apps like Spotify, Discord, etc., in the background.

If you are unable to allocate more than 1 GB to your Minecraft, it means your computer has a 32bit version of Java installed in its system. To resolve this, all you need to do is uninstall Java and then install the 64bit version on your system. Finally, restart your PC.

While allocating more RAM to Minecraft will inevitably enhance your Minecraft experience, the problems will reduce, but too much of something is also not good.

If you allocate too much RAM to your Minecraft while ignoring the other system requirements, your overall system performance will go down. So, it’s always a good idea to allocate at least 1 GB for different processes not related to gaming.
