For Windows

For Linux

2) Once you learned that you have a 64-bit system, let’s start installing Java 64x. (If you still have a 32-bit system, you need to reinstall the system to 64-bit, provided that the processor supports a 64-bit scheme.)

For Windows

Download the Java 64 installer, run it and the following instructions (just click Install). Download Java 64x Windows

For Linux

Download the Java 64 installer, run it and the following instructions (just click Install).

How to allocate more RAM (memory) to Minecraft

Based on this post by this user, updated and corrected for 1.18.

These are some basic steps on how to allocate more RAM to your game.

Attention:

32-bit system only supports up to 4GB RAM memory. Therefore, most 32-bit based systems only support a maximum of 2GB to be allocated to Java. The limit depends on the system, if you got an error, try less allocation.

If you are not using the native Java that comes with the launcher, be sure to use the latest and correct version of Java (64bit on 64bit-OS-Systems is recommended).

How much RAM do I have?

The easiest way to see how much RAM you have on Windows is to open the Task Manager and change to the Performance Tab. Look how much Physical Memory is available. On MacOS, go to the Apple Menu, select About This Mac. This window shows you your total amount of RAM.

Note that other programs and your system also need RAM to work. For example, if you run TeamSpeak or Firefox in background, you should leave enough memory for this software to run.

Some numbers for reference:

It is recommended to never allocate more than half your system RAM to the game. Also be aware that allocating more RAM does not necessarily make the game faster.

Very helpful, thank you!

Let’s say I have 64Gb RAM on my laptop, if I give Minecraft 32Gb, do you know if Minecraft itself can slow down if it has access to too much ram?

In some cases I have actually seen a large amount of RAM reduce game speed. If we’re talking in general terms, you don’t ever need 32GB of RAM assigned to your game. Unless of course, you’re running a heavy modpack

A 4000×4000 texture pack with 16 variants for every block type.

You may need more than 2GB there

How to allocate more RAM to ‘Minecraft’ and help your game or server run more smoothly

But the bigger and more beautiful your «Minecraft» world is, the more RAM it needs to run. And if not enough RAM is allocated to the game, it’ll load slowly, frames will stutter, and it might even crash.

Fortunately, there’s a solution. There are several different ways to allocate more RAM to «Minecraft,» each of them fairly simple and straightforward.

And if you run your own «Minecraft» server, you can also allocate more RAM to it, which makes it so more people can play on the server at once.

Here’s a rundown of all the ways to allocate more RAM to ‘Minecraft.’

Important: This guide only applies to «Minecraft: Java Edition.» If you’re playing «Bedrock Edition,» also known as «Minecraft for Windows 10,» there’s no built-in way to control how much RAM is used.

How to allocate more RAM to ‘Minecraft’

To change how much RAM «Minecraft» can use, you’ll have to change the settings of your Minecraft Launcher app. The launcher app is the program you use to launch «Minecraft.»

There are several different launcher apps you might use, depending on what sort of mods you have installed. We’ll go through three of the most popular ones, starting with the standard «vanilla» launcher that most people use.

Quick tip: You should always have at least 2 gigabytes (GB) of RAM allocated to «Minecraft.» If you’re planning on using a lot of mods, consider raising it to 4GB or 6GB.

Just be careful not to take more RAM than your computer actually has available. You’ll want to leave at least half the RAM available for the rest of your computer to use.

Allocating RAM using the default ‘Minecraft’ launcher

If you’re familiar with «Minecraft,» you’re probably also familiar with the game’s default launcher app, called «Minecraft Launcher.» Here’s how to use it to reallocate RAM.

1. Open the Minecraft Launcher and select the «Installations» tab at the top.

2. Scroll your mouse over the «Minecraft» version that you want to allocate RAM to, then click the three dots on the right and select «Edit.»

3. Select «More Options» in the lower-right corner of the screen to reveal two additional fields.

4. At the beginning of the «JVM Arguments» field, there’s a bit of code that reads «-Xmx2G» or something similar — the «2G» represents how many gigabytes of RAM «Minecraft» can currently use (in this case, 2GB). Change that number to change how much RAM is allocated. Leave the rest of the text as is.

5. Tap «Save» to finalize your changes.

Allocating RAM using the CurseForge ‘Minecraft’ launcher

1. Launch the CurseForge app. Access «Settings» by clicking the gear icon in the lower left corner of the screen.

2. There’s a «Game Specific» section in the column on the left side of the settings page. Select «Minecraft.»

3. Scroll down to «Java Settings» where you’ll see «Allocated Memory» with a slider. From here, simply drag and drop the orange ball on the slider to your preferred RAM allocation. Any change will be automatically saved.

Quick tip: CurseForge, most third-party launchers, measures RAM usage in megabytes (MB), not gigabytes (GB). Just remember that in cases like these, 1024MB equals 1GB.

Allocating RAM using the ATLauncher ‘Minecraft’ launcher

1. Boot up the ATLauncher and click «Settings,» located on the right panel.

2. At the top of the settings page, you’ll see several tabs. Click the «Java/Minecraft» tab.

3. You’ll see a list of adjustable properties. The second listed is for «Maximum Memory/RAM» and that’s the number you’ll want to increase. It’s listed in megabytes, so remember that 1024MB equals 1GB.

4. After you’ve adjusted the max RAM, make sure you click «Save» at the bottom to confirm your changes.

How to allocate RAM to a Minecraft server you run on a PC

Finally, you may be running your own Minecraft server. If the server doesn’t have enough RAM, it won’t be able to load or support users playing on it, and any changes you make in-game will lag.

If you want to increase how much RAM your server can use, here’s how. Just note that these steps are for servers running from a Windows 10 PC — the method to do this on a Mac or Linux computer will differ.

1. Open the folder that houses all your Minecraft server files.

2. Right-click on any black space in the folder, then select «New» and «Text Document.» You can leave the document unnamed for now.

3. Open the document, then paste the following code:

In place of «####» insert how much RAM you’d like to allocate. You’ll write the allocation in megabytes — so if you want to allocate 2GB, for instance, you’ll enter «2048,» making the code:

4. Now click «File,» then «Save As…» In the menu that opens, change the «Save as type» to «All Files.» Save it.

5. Once the document is saved and visible in your folder, rename it «file server launcher.bat» — without the quotes.
