How much RAM for a Minecraft server

Your Minecraft server will not perform well without adequate RAM. The more players and mods you include in your server, the more RAM allocation becomes. While there is a recommended minimum for every Minecraft version, that doesn’t mean you have to stick to the lowest point.

RAM and Minecraft

RAM is an important consideration when deciding the size of your world, taking into account structures, mods, and players. The more the server is modified and expanded, the more RAM the server will need. Without adequate RAM, your server may lag or otherwise not perform as well. It will also be more difficult for several players to be at the same time.

How much RAM for a Minecraft server

If you look at the professional Minecraft hosting plans, there is a base of 2 GB of RAM for minimum worlds with ten plugins and ten players. The largest world that can support over 50 mods, 150 players, and 150 GB requires at least 15 GB of RAM.

Here’s a quick rundown of how much RAM you’ll need depending on the server and mods:

  • 15 players and 25 mods: at least 3 GB of RAM.
  • 25 players and 40 mods: at least 4 GB of RAM.
  • 30 players and 45 mods: at least 5 GB of RAM.
  • 40 players and 50 mods: at least 6 GB of RAM.
  • 90 players and 50 mods: at least 8 GB of RAM.
  • 150 players and 50 mods: Up to 100 GB in size requires at least 10 GB of RAM.

You can see that the servers with more players require more RAM, even if the mods are not increased. On a related note, larger worlds with the same players and mods will also need more RAM. It means that you need to adjust your RAM as your world size, player base, and mod needs increase.

How to allocate more RAM to the Minecraft server

Allocating RAM is simple whether you are renting a server or managing your own. Of course, if you are renting a server, all you need to do is go to your control panel and upgrade your plan to include more RAM. It will cost more as your needs increase. If you are managing your own server, however, knowing how to change your RAM allocation if necessary is helpful.

RAM allocation on Java Edition

You can change the RAM directly from the Java edition launcher. If you are using a different launcher or your standard launcher is having problems, you can always change it through a different one.

  1. Open your Minecraft launcher.
  2. Click on Facilities.
  3. Click on the three-dot button for the installation you want to manage.

  4. Click on “More options. “

  5. Examine the “JVM arguments” line.

  6. Change the number to “Xmx6G”To include the amount of RAM you want to allocate. For example, it should say “Xmx6G” to use 6 GB of RAM.

You must manage each installation separately.

RAM allocation on third party launchers

Third-party launchers have all the JVM arguments in different places, but the overall steps are the same as changing them on the Java edition. Find preferences or edit the profile. Both of these locations are likely to have the JVM arguments that you can adjust to give Minecraft more RAM.

RAM Allocation on Forge Server

You can edit the text document in your Forge Server installation to change the amount of RAM allocated to Minecraft.

  1. Open the folder containing your Forge server installation.
  2. Open the “To throw“text document.
  3. Make sure your Forge installation matches the .jar installation listed in the document.

  4. Type the amount of RAM you want to use in the Xmx command line.

  5. to safeguard the document.
  6. Use the “To throw”File option to start your Forge server.

If you change your Forge settings often, consider using ServerStart scripts to manage RAM allocation and other settings.

  1. Go to Minecraft tab in Settings.
  2. Click on the allocated memory slider bubble.

Why can’t I allocate more RAM to Minecraft

Sometimes people have a hard time allocating more RAM to Minecraft. If you are experiencing this problem, it is likely that the Java SE Development Kit for Windows x64 is not installed. It will not work if you are using the 32 bit version.

You can also run the Windows 10 edition of Minecraft. Windows automatically manages the RAM on that particular game, so you don’t need to change it.

Can you allocate more than 12 GB of RAM to Minecraft

You can allocate as much RAM as you have on your system. You can certainly add more than 12 GB of RAM to Minecraft since professional hosts offer up to 15 GB.

You always want to have at least 2 GB of RAM to run Minecraft. However, most people get better results if they set the minimum amount to 4GB instead. The performance improvement is noticeable enough that it is worth it, even if you are using limited RAM.

Tips for adding RAM to Minecraft

You shouldn’t try to add more RAM to Minecraft than you have on the computer hosting the game server. Make sure you have enough left over to run any other program or process you are using as well. It’s imperative that you leave enough RAM unallocated if you’re playing on the same computer, as your graphics might not be as smooth if you’re running low on memory.

Don’t feel like you have to stick to a set amount of RAM. You can try to change for different amounts at different times. If you have a sudden influx of gamers, taking a brief stop to allocate more RAM can help it run smoothly while you’re heavily populated. If only a few people are on normally, you can reduce RAM.

Sometimes adding too much RAM can cause servers to lag or performance issues. Try reducing the RAM if you find that your server is not performing as well after increasing it. You may need to experiment a bit to find the perfect amount.
