ATM10 Server Files: Where to Download, Install, and Update (2026)

ATM10 server files are the official server pack for All The Mods 10: configs, mods folder, start scripts and a bundled NeoForge installer. You should always match the exact version your players use on the client.

Quick Answers

• Where are the ATM10 server files? On the official All The Mods 10 page on CurseForge. Open the file for your client version and download the server pack listed under Additional Files.
• How much RAM does ATM10 need? We recommend 12 GB for 1 to 5 players, 16 GB for 5 to 15 players and 32 GB for 15 or more. The server files set -Xms4G -Xmx8G in user_jvm_args.txt, so raise -Xmx to fit your plan.
• Forge or NeoForge? Use NeoForge for current ATM10 builds. Do not swap to Forge unless the pack authors explicitly publish a Forge server pack.
• Why does ATM10 crash on first start? The usual causes are wrong Java version, wrong NeoForge version, client-only mods, missing EULA, or not enough heap.

Where to download

Open the All The Mods 10 project page on CurseForge, go to the Files tab, open the version you want and look under Additional Files. For 8.2 (released 22 September 2026) the server pack is ServerFiles-8.2.zip, about 1.1 GB. The 189.8 MB zip on the same page is the client pack, not the server files.

Avoid random repacks. Wrong versions cause connection errors or missing mods.

What is inside the server pack

The 8.2 server files contain:

• startserver.sh and startserver.bat, the start scripts for Linux and Windows
• user_jvm_args.txt with the Java flags (-Xms4G -Xmx8G plus G1 garbage collector settings)
• the NeoForge installer (neoforge-21.1.251-installer.jar)
• the mods folder (464 mod jars), plus config, defaultconfigs, kubejs, datapacks and local
• server-icon.png

There is no readme. The server mods folder has fewer jars than the client pack on purpose: the team leaves out 26 client-side mods and the Simple Backups mod. Do not copy your client mods folder onto the server. It also means the server files ship without a backup mod, so set up world backups through your host or add a backup mod yourself.

Install outline

1. RAM: Plan for 12 GB for 1 to 5 players, 16 GB for 5 to 15 and 32 GB above that; see ATM10 requirements. The pack's user_jvm_args.txt caps the Java heap at 8 GB (-Xmx8G), so raise -Xmx to fit your plan and leave some room for Java itself.
2. Java: ATM10 requires Java 21. The official start script stops if Java is missing or older than 21.
3. NeoForge: ATM10 runs on Minecraft 1.21.1 with NeoForge (8.2 uses NeoForge 21.1.251). You do not need a separate installer: on the first run, startserver installs NeoForge from the bundled installer when there is no libraries folder yet. Do not interrupt it. On a host that sets up NeoForge for you, use the same NeoForge version as the pack and upload the server files over SFTP.
4. First start: The script writes a default server.properties if none exists (view-distance 8, simulation-distance 5, allow-flight on). The server then stops because the EULA is not accepted yet. The script restarts the server 10 seconds after any exit, so stop the script yourself or set the environment variable ATM10_RESTART=false. With ATM10_INSTALL_ONLY=true it installs NeoForge without starting the server.
5. EULA: Open eula.txt, set eula=true and start the server again. Do not edit server-ip; the official guide warns that changing it can stop the server from starting.

Updates

1. Back up the world folder, important config overrides and any kubejs scripts you changed.
2. Download the new server pack for the target version.
3. Follow pack changelog for breaking changes (mod removals, worldgen changes).
4. Delete mods, config, defaultconfigs and kubejs, then extract the new ones. If the NeoForge version changed, also delete libraries and use the new start scripts and installer.
5. Prefer test on a copy before swapping a live community world.

Where to host

Pick a region close to your players. Space-Node runs Minecraft servers in 9 regions: the Netherlands, Germany, Poland, Canada, the USA (California and Virginia), Singapore, India and Australia. For European groups, compare Netherlands vs Germany for Minecraft. Our All The Mods 10 server hosting plans start at 12 GB for 1 to 5 players.

Frequently Asked Questions

"Are ATM10 server files free?"

Yes, the official server pack from CurseForge is free like the pack. You pay for hosting and hardware, not for the mod files themselves.

"Can I use Forge instead of NeoForge for ATM10?"

No for current ATM10 lines. The pack is built for NeoForge. Mixing loaders breaks the install.

"Why does my server crash on start?"

Common causes: wrong Java, wrong NeoForge build, client-only mods accidentally in mods, or not enough RAM for the JVM heap.
