How To Allocate More RAM To Minecraft

how to allocate more ram to minecraft

This post will explain how to allocate more ram to Minecraft. Minecraft, despite its minimal graphical style and straightforward gameplay, can be a time-consuming application. A lot is going on in the background, especially when it comes to Redstone-heavy buildings.

When mods are added to the mix, the regular RAM required to operate Minecraft becomes insufficient. You’ll start to experience stuttering, crashes, and other issues if you don’t have enough RAM, which will make the game nearly unplayable.

How To Allocate More RAM To Minecraft

In this article, you can know about how to allocate more ram to Minecraft here are the details below;

The good news is that increasing Minecraft’s RAM is relatively simple. The other good news is that there are multiple options.

Make Certain You Have Enough RAM

The first step is to determine how much RAM your computer has. This is a simple task.

Go and select the Settings icon from the Start menu (it looks like a gear).

In order to know more, click About.

Look for Installed RAM under Device Specifications. The number beside it indicates how much RAM you have available.

A least 2 GB of RAM is required for Minecraft, while 4 GB is recommended. You’re in a good position if you have more than that. You can now allocate Minecraft as much RAM as it requires to satiate its hunger.

Method 1: Use The Default Launcher To Allot RAM

Although the default Minecraft launcher has evolved over time, you may still allocate the amount of RAM available to Minecraft.

  • Launch Minecraft and choose the version you wish to play (either Bedrock or Java)
  • From the top tabs, select Installations. You’ll see a list of releases below, but you can only see the most recent version if you haven’t set up any specific versions to play.
  • Hover your cursor over it and select Edit from the three white dots on the right side.
  • A screen will appear with the installation’s name, version, and a few other options. Scroll down until you see JVM Arguments under More Options. There will be many codes in this box, but you only need to worry about the first snippet, which looks like this:
  • The figure at the endpoint indicates how much RAM Minecraft consumes. Replace the “2” with the number of RAM you want Minecraft to use.

It’s possible to make it use all of the RAM you have available, but whether it does so depends on whether you have anything else open and running in the background.


  • After you’ve made your changes, click Save and start the game. You should see an immediate difference in performance.

Method 2: Use the ATLauncher to allocate RAM.

You’re probably familiar with the ATLauncher for Minecraft if you’ve downloaded mods or played a lot of Sky Factory. Setting aside additional RAM with the ATLauncher is equally easier than with the default launcher, especially since you won’t have to work with any code.

  • Open the ATLauncher application.
  • A list of settings can be found on the right side of the launcher. At the top of the screen, go to Settings and then the Java/Minecraft tab.
  • There are several alternatives to pick from, but the second one – Maximum Memory/RAM – is the one you want. You can enter in the amount you want to allocate, but clicking the up and down arrows is the simplest option. This changes the amount of RAM allotted in 0.5 GB increments.
  • When you’ve decided how much RAM you want to utilize, click Save. You’ll need additional RAM if you’re playing a mod-heavy pack like SkyFactory, or the game won’t allocate. Sky Factory 4 required at least 4 GB of RAM in our tests, or it would crash on launch.

Method three: Use the Twitch/Curse Launcher to allocate RAM.

You could also use the Twitch launcher to play various Minecraft mods (or regular Minecraft). Changing the settings in this launcher is just as simple as it is in the ATLauncher above, but the first process for doing so is a little different.

  • Click the three lines in the top-right corner, then Files, then Settings. To access the Settings menu from within the launcher, press CTRL + Comma.
  • Next, go to Minecraft and scroll all the way down to the bottom of the screen. A section titled Java Settings will appear. Look for the Allocated Memory slider and click it.
  • Sky Factory 4 gets 3,228 MB of RAM by default. To give more or less RAM for the game, adjust the slider to the left or right. The RAM is increased or decreased in 0.25 GB increments using the slider.
  • You’re done once you’ve moved the slider. Return to Mods, choose Minecraft and begin playing your better-performing game. That’s all there is to it.

While assigning additional RAM to Minecraft can (and often does) improve speed, there are times when allocating too much RAM can degrade overall system performance.

RAM is also required by other parts of your computer. While these won’t have much of an influence if they’re not operating at the same time as a game, it’s usually a good idea to set aside at least 1 GB of RAM for non-gaming operations.

If you alter your RAM settings and still don’t get the performance you want—or if your PC shows an incorrect amount of RAM—it could mean you have a memory problem. It will be good to check for faulty memory regularly.

The good news is that replacing your RAM is straightforward, even if you have a problem with it. In fact, with memory prices continuing to plummet, it’s worth considering buying more RAM for your system if you want to see an even higher performance.
