How to Allocate More RAM to Minecraft? [All Launchers]

Lags are the worst nightmare for every gamer. And, what could be worse than facing stutters or lags on Minecraft when it isn’t a graphics-heavy game? Fortunately, you can allocate more RAM to Minecraft to avoid that situation. But, you don’t know how to do that? No problem, a lot of Minecrafters don’t.

If you want to learn how to do that, this post is specially written for you. Here, I will guide you on how to allocate more RAM to Minecraft on different launchers, including the default/vanilla one. Learning this will help you to play the game smoothly without any stutters.

How much RAM does Minecraft need?

Minecraft is a massively popular sandbox video game. It is one of the most successful games currently and is rapidly moving to become the greatest of all time. The graphics of the game may appear lego-like and not so attractive or advanced. And, the gameplay also seems simplistic. Still, it needs a good amount of PC resources to run swiftly. It is definitely NOT a lightweight game.

Minecraft requires a minimum of 2 GB of RAM to run properly. However, the recommended RAM requirement of the game is 4GB. If you have RAM more than that, then you are good to go. You can now allocate more RAM to Minecraft to make it run without any lags. Also, you can use various mods, texture packs, and even shaders without any stutters.

Why do you allocate more RAM to Minecraft?

Minecraft uses 1-2 GB of RAM by default on any launcher. However, sometimes the standard amount of RAM allocated to Minecraft becomes insufficient and the game starts lagging, crashing, or freezing. The game becomes completely unplayable then. To avoid this situation, you can allocate more RAM to Minecraft. It will give your game an impressive performance boost.

Also, if you are fond of using many mods, resources packs, or shaders, you will have to allocate more RAM to the game. Or else, your additions will fail to run properly, and the game will eventually crash. In short, more RAM means better performance.

Check if you have enough RAM to allocate to Minecraft

Now that you have decided to allocate more RAM to Minecraft, you need to check if you have enough of it. To check the available RAM on your PC, follow these simple steps:

  • Press the Windows + I key on the keyboard to access Settings.
  • Scroll down and click on About.
  • Look for Installed RAM under Device Specifications.
  • Here, you can see the available RAM on your PC.

If you have enough RAM, then you can proceed further. But, if you have RAM less than 4GB, then I wouldn’t recommend doing so as it may damage your PC.

How to Allocate More RAM to Minecraft?

The methods to allocate more RAM to Minecraft is different on various launchers. If you use the default Vanilla launcher, then you can do that by going to the ‘Installations’ tab. But, if you use the Twitch launcher, then the setting is present under the ‘Java’ settings section, and so on. I will explain the methods briefly for every launcher out there.

On Default Launcher

Follow these steps to allocate more RAM on the default launcher:

  • Run the Minecraft launcher and choose the version you want to play.
  • Now click on the Installations tab from the top section.

  • Next, click on Edit.
  • You will then see a new window with the game information. Here, click on More Options, and scroll down to find JVM Arguments.
  • In this box, you will see a code starting with Xmx2G. The 2G in it is the amount of allocated RAM.
  • Change the ‘2’ in this to whatever amount of RAM you want to allocate. For example, type 4 to allocate 4 GB of RAM.
  • Once done, click on Save to apply the changes.
  • Finally, launch the game and start playing.
