Installation Guide: How to Run the ATM10 Modpack on Your Windows Server

All the Mods 10 (ATM10) is the definitive pack of 2026, with over 300 mods combining the best of technology and magic. Installing such a large modpack requires a bit more care than a regular Vanilla server.

In this guide, we will simplify the server installation process so you and your friends can start playing quickly. If you're not familiar with the most played packs yet, see our list of 5 popular modpacks of 2026.

1. Hardware Requirements (Mandatory)

ATM10 is a "giant." For it to run without major lag (low TPS), your PC must have:

  • RAM: Minimum of 16GB total (allocating 8GB to 12GB for the server).
  • Processor: A modern CPU with good "Single Core" performance (like a Ryzen 5 5000+ or Intel i5 12th gen+).
  • Storage: SSD is highly recommended; standard HDDs can cause slowness when loading "chunks".

2. Downloading the "Server Pack"

Never try to drag your game folder (client) to the server! Modpacks have a specific version for servers.

  1. Access the official CurseForge site or use your preferred launcher (Prism, GDLauncher).
  2. Search for All the Mods 10.
  3. In the "Files" tab, look for the latest version marked as Server Pack or Server Files.
  4. Download the .zip file.

3. Preparing the Files

Create a dedicated folder for your server (e.g., C:\ATM10_Server). Extract the contents of the downloaded zip into this folder.

You will see files like start.bat (or run.bat), the mods folder, config, and defaultconfigs. The required Java version is usually indicated in the server log file, but for ATM10 in 2026, you will need Java 21 (or higher).

4. The First Start and Accepting the EULA

  1. Double-click the start.bat file.
  2. The console will open and close quickly. This is normal.
  3. Open the eula.txt file that appeared and change eula=false to eula=true.
  4. Save and close.

5. Adjusting RAM in the Script

Right-click on start.bat and choose "Edit." Look for lines containing -Xmx. Adjust it to the amount of RAM you want to allocate. Example for 10GB: 

@echo off
java -Xmx10G -Xms10G -jar forge-server.jar nogui
pause

Tip: The .jar filename may vary depending on the exact version of Forge or Fabric used by the modpack.

6. Connecting and Resolving Conflicts

With the server running, open your Minecraft (client) with ATM10 installed and connect using localhost (if on the same PC) or your Public IP for external friends.

Common Issue: If the server takes a long time to start ("Starting..."), do not interrupt it! Large modpacks take between 3 to 8 minutes to load all mods for the first time.

Conclusion

Installing ATM10 is the first step toward an epic journey. Now that your server is online, consider reading about automatic backups, as worlds with hundreds of mods are more prone to errors during power outages.
