RAM becomes essential for a smooth Minecraft gameplay. By any chance, if you see Minecraft lagging or crashing consistently, it’s time to spare more memory to Minecraft. And in this article, I will show you exactly how to allocate more RAM to Minecraft.

So, Why should you allocate more RAM to Minecraft? There are two chief reasons: 1) To get rid of lag/bottleneck or game crashing continuously. 2) More RAM means that objects in Minecraft will render at a better rate and to a good distance.

If these two points are enough to convince you, let us proceed further; if not, read this Reddit thread. And see the exact method to increase the RAM allocation to your Minecraft server.

How to allocate more RAM to Minecraft Server?

How to allocate more RAM to Minecraft on Windows 10?

First, let us see the proper steps you need to take to increase RAM allocated to minecraft server. Follow these exact steps in order to maximise your chances of increasing the memory to Minecraft.

1) Check your System Information

Go to the settings. Then, have a look at your system information. Check the system type and the RAM on your PC. It will let you know how much memory you have and what amount you can allocate to the Minecraft servers.

If your system type is not X64 based, you cannot allocate more than 4GB of memory to Minecraft 🙁

2) Get the right Java Version

Getting the correct version of Java is critical to maximizing RAM’s amount to Minecraft. If you have a 32-bit java on a system that supports a 64-bit java version, you’ll not be doing yourself a favor.

So, before proceeding further, check your java version here. And if you do not have a suitable version, download it before moving to the next step.

3) Open the Minecraft Launcher

So, the real question is, how much RAM should you allocate to Minecraft? The amount of RAM you need to give to Minecraft depends on two factors. The first one is the amount of RAM you have at your end. And the other things is mods. Do you have any mods? And if Yes, then how many mods do you have?

If you have a Modded Minecraft version, you have to allocate much more RAM than the Non-Modded Version. As a rule of thumb, never give more than half the memory to Minecraft.

I have a regular Non-modded version of Minecraft, and I have dedicated 4GB of RAM to Minecraft servers. It works fine for me. If you have a modded version, you can check by trial and error process. It boils down to you, allocating randomly and seeing what works best.

4) Check the Latest release

Under installations, check for the latest release. Click on the three dots that appear right next to the play button. This is the actual setting we need to go to increase the dedicated RAM to Minecraft servers.

For this step, all you need to do is to click on the three dots and then select ‘Edit‘.

5) Click on More options

So, once you are in the Edit setting, you will see the game version, directory and the resolution.

But, we are not interested in that. Instead click on the ‘more options‘ that appear right below the resolution box.

6) Decide how much RAM you want to allocate

This step is all about deciding how much RAM is going to be sufficient for your Minecraft server. Also, never dedicate more than half of RAM to the MC server.

For most cases, what I have seen is that 4 GB Ram is sufficient for Vanilla Minecraft. Vanilla Minecraft is another name given to Non modded version of Minecraft.

And if you play the modded version of Minecraft, allocating 8 GB of RAM will work fine.

For players who do not have 8GB of Ram, you can allocate half the amount of RAM you have to Minecraft.

7) Change the allocated RAM to Minecraft

Now, follow this step very carefully.

All you need is to change is the ‘2‘ in (-Xmx2G) to whatever RAM you want to allocate.

For example: If I want to allocate 4GB of RAM to Minecraft, that will look like (-Xmx4G).

Open the text edit on your MAC. And then create a document In the same folder as that of Minecraft server.

As the text edit opens up, go to the topbar and select Make Plain Text under the Format dropdown.

2) Copy the Command

#!/bin/bash
cd “$(dirname “$0”)”
exec java -Xms2G -Xmx2G -jar your Minecraft server filename

Copy this exact command and type it in the text edit document. Here the ‘2G’ means we are allocating 2GB RAM to the Minecraft server. You can change this as per your requirements.

IMPORTANT NOTE: please type the minecraft server as your own.

After you have finished typing in the command, save the document as ‘start.command‘. Close the file.

3) Open terminal

NOTE: MAKE SURE THAT THE START.COMMAND FILE IS IN THE SAME DOCUMENT AS THAT OF MINECRAFT SERVER.
