ATM10 Aeronautics server hosting & setup guide
An ATM10 Aeronautics server needs Java 21 and about 10–12 GB of RAM for up to 8 players.
An All the Mods 10 variant on NeoForge 1.21.1 with Create Aeronautics worked in, reworked power and pipes for a more unified game, overhauled world generation, and new mods such as Neo Vitae and Excessive Utilities.
Pack details checked by hand against All the Mods 10 Aeronautics on CurseForge on October 5, 2026.
All the Mods 10 Aeronautics is a NeoForge modpack for Minecraft 1.21.1 with 425 mods. We'd pick our Heavy plan (12 GB) for it.
- The pack is still before version 1.0 (0.7.1 when we checked), so expect frequent updates and take a backup before each one.
- CurseForge lists ATM10AERO-0.7.1-server.zip as an additional file of version 0.7.1 but doesn't mark it as that version's server pack, so an installer that follows CurseForge's server-pack link won't find it. Version 0.7.0 has no server files at all.

How much RAM does an ATM10 Aeronautics server need?
| Players online | RAM | DSN plan |
|---|---|---|
| 1–3 players | About 9–10 GB | Heavy (12 GB) |
| 4–8 players | About 10–12 GB | Heavy (12 GB) |
| 9–15 players | About 11.5–15 GB | Heavy (12 GB) if players stay closeMore than 12 GB if they spread out. |
Estimated from 425 mods with our RAM calculator, not measured: low end if players stay together, high end if they spread out.
With 9–15 players spread across the map, ATM10 Aeronautics can need more than 12 GB, our biggest plan. A lower view distance and a pre-generated world help it fit; past that, a host with bigger plans is the better choice.
Set Java's heap (-Xmx) 10–15% under the RAM you have, about -Xmx10500M on 12 GB. NeoForge 1.21.1 reads it from user_jvm_args.txt: uncomment the -Xmx line. RAM guide.

How to make an ATM10 Aeronautics server on your own PC
What's specific to ATM10 Aeronautics, step by step. The full walkthrough for any pack: how to make a modded Minecraft server.
- Install Java 21.
Check with
java -version. Java version chart. - Get the server files.
Download the official server files for the version your players use and unzip them into an empty folder. Follow the readme that comes with them.
- Start it and accept the EULA.
Run the start script in the server files, or the
run.sh/run.batthe NeoForge 1.21.1 installer writes, then seteula=trueineula.txtif you accept Mojang's EULA (EULA step). With 425 mods, the first start takes minutes. - Set the RAM with
-Xmx, sized from the table above. - Let friends connect: forward TCP 25565, or use a tunnel or host behind CGNAT (can't connect?).
Or run ATM10 Aeronautics on DSN
Once we relaunch (join the launch list), on DSN you'd install ATM10 Aeronautics from the panel's CurseForge modpack installer, pick Java 21 on the Startup tab and accept the EULA in the console. No port forwarding. We haven't tested the panel's installer with this pack: CurseForge doesn't mark the server zip as the version's server pack, so an installer may not find it. If the server starts without the pack's mods, upload the server zip by hand.
How to play ATM10 Aeronautics with friends

Lag and performance on ATM10 Aeronautics
Can't keep up! Is the server overloaded? means ticks take longer than 50 ms; more RAM won't fix that once ATM10 Aeronautics has enough (tick lag guide). For ATM10 Aeronautics:
- Measure first: spark's
