If you love playing Minecraft and want to use mods, setting up a modded Minecraft server is a fantastic idea. But one question that pops into everyone’s mind is: How much RAM do I need for a modded Minecraft server? So, let’s find the answer and figure out how to make your server run smoothly without any lag.

How Much RAM Do You Need for a Modded Minecraft Server?

The amount of RAM you need for a modded Minecraft server depends on how many players you have, which mods you’re using, and the size of your server. But generally, you can follow these guidelines:

1. Light Modpacks (50-100 Mods): If your server has light modpacks and around 5-10 players, 4GB to 6GB of RAM should be enough.
2. Medium Modpacks (100-200 Mods): If you’re using more mods and have around 10-20 players, you’ll need 6GB to 8GB of RAM.
3. Heavy Modpacks (200+ Mods): If you’re running heavy modpacks with 20+ players, you’ll need 8GB to 12GB of RAM or even more.

Let me share my personal experience. I used to have a low-end PC with only 4GB of RAM. When I set up a modded server, the game would lag a lot. Then, I upgraded my RAM to 8GB, and now my server runs smoothly, and all the players are happy.

How to Figure Out How Much RAM You Need?

If you’re confused about how much RAM you need, follow these steps:

1. Check the Modpack: Look at the modpack description. Usually, the minimum and recommended RAM are mentioned there.
2. Player Count: If you have more players on your server, you’ll need more RAM.
3. Monitor Server Performance: After running the server, check its performance. If there’s lag or crashes, you’ll need to increase the RAM.

How I Increased My Server’s RAM

I used to have only 4GB of RAM, and my modded server was running super slow. Here’s what I did to fix it:

1. Upgraded My RAM: I added another 4GB RAM stick to my PC, bringing the total to 8GB.
2. Optimized Server Settings: I adjusted the settings in the server.properties file, like reducing the view-distance.
3. Managed Mods: I removed unnecessary mods that were consuming too much RAM.

After these changes, my server started running smoothly, and the players were happy.

More Tips for Running a Modded Minecraft Server

1. Use an SSD: If you use an SSD, your server will run faster because of the higher read/write speeds.
2. Optimize Java Arguments: Adjust the Java arguments when starting the server. For example:
   -Xmx8G -Xms8G

   This command allocates 8GB of RAM to the server.

3. Take Regular Backups: Crashes and issues are common in modded servers, so don’t forget to take regular backups.

Conclusion

To sum it up, the amount of RAM you need for a modded Minecraft server depends on the mods, players, and server size. If you’re using light modpacks, 4GB-6GB of RAM should be enough. But if you’re running heavy modpacks, you’ll need 8GB or more. From my personal experience, upgrading your RAM can significantly improve server performance.
