How to Allocate More Ram to a Minecraft Server

Creating a Minecraft server and hosting it has become a popular model for newbie Minecraft players.

Some people create Minecraft servers to play with their friends, while others had found it more profitable to host one on their own and monetize it.

No matter the case sometimes we need to increase the Ram of our Minecraft server, due to having too many players, heavy server plugins, or even too many plugins.

Increasing the allocated ram to your Minecraft server can potentially keep up the server running smooth and prevent crashes from occurring in your server.

Why is Ram Important for a Minecraft Server

Ram is the source used for upkeeping your Minecraft server alive. The more you dedicate, the better your server will operate.

While this may sound strange, there are some servers, that operate with only 2 to 3 GBs of Ram and are still giving out great results.

That is because they are using a small to no amount of Minecraft server plugins and have a small player base.

But if your Minecraft server keeps on crashing, you will need to find the source. It can be due to too incompatible and buggy plugins, or too many players.

How to Allocate More Ram to my Minecraft Server

If you want to allocate more ram to your Minecraft server, all you need to do is to open up your server folder.

Make sure to make a duplicate in any case, so you can first test things out and see how it works.

If you have an online server with players inside it, you should pick a date and time, in which you will be performing maintenance, otherwise, you may lose players.

For allocating more ram to your Minecraft server you need to:

  • Create a new notepad file.
  • Add this line of code: Java -Xmx4096M -Xms4096M -jar server.jar -nogui
  • On the next line, you will need to add: PAUSE
  • Click on Save, then Save As and name your file start.bat
  • This will create a .bat file for your Minecraft server and use the specified Ram.
  • Delete the notepad file and open the start.bat one.

Now your server will be operating on 4GBs of Ram.

If you already have the start.bat file, you don’t need to create another one or follow the steps. All you need to do is edit the “Xmx” and “Xms” numbers, which will increase the ram on your Minecraft server.

Keep in mind, that when you are adding Ram to your Minecraft server, you need to specify it in MBs and not GBs.

The counting starts from 512MBs and multiplies by 2 for every GB you want to add.

Can Increasing Ram on my Minecraft Server Slow Down my Computer

Depending on the Ram you have on your computer, you will need to be cautious. If you allocate too much Ram to your Minecraft server, your computer might run slower and eventually crash.

Before allocating any Ram to a Minecraft server, we need to check how much Ram is installed in the machine and how much we are currently using.

How to check how much Ram I have on my computer?

Open the file explorer on your computer and click on “This PC”. Right after you go to it, you can right-click on it and choose properties.

Below you will be able to see how much Ram is installed on your computer.

But we can’t allocate all the Ram, just because we have plenty of it, can we? The answer is no. You need to check how much Ram your computer is using, so you prevent damaging your computer.

How can I check how much Ram my computer is using?

The fastest and most simple way is to use the Task Manager, which is built into every Windows PC.

All you have to do is press certain buttons in a combination, and you will be taken to a screen, where you have to choose your option.

  • First of all, we need to press CTRL+ALT+DELETE.
  • Then we choose the Task Manager, which is located at the bottom of our choices.
  • Once the task Task Manager pops up, we will be able to see how much Ram is actually used and we can safely allocate a partial amount of it to our Minecraft server.

The best way to test how much Ram you are using is by opening the applications, which you are going to use while you are playing.

Don’t forget to open up Minecraft, because if you are going to enter the server and play with your friends, it also has its requirements.

Check how much Ram you are using when everything except your server is open and then allocate Ram to your server.

Keeping at least 30% of your remaining Ram will assure you that your PC won’t get damaged or Windows crash.
