All the Mods 9 on Your Own Server
All the Mods 9 is the big tech and magic pack for Minecraft 1.20.1 with the ATM Star as the ultimate goal. With us, it runs with 10 GB RAM and only on the paid plan, because even the empty server uses more memory than the free plan has at all.

How ATM9 Is Installed with Us
The All the Mods 9 server pack has a quirk: the developers put all the files into a subfolder. During our check on September 26, 2026, the server therefore initially started as an empty Forge without mods, even though every automated test reported green. Since then, our installation moves the contents out of the subfolder to the top level and checks whether mods have actually arrived.
After the fix, there were 418 active mods in the mods folder, plus Simple Backups as a disabled file. The server runs on Minecraft 1.20.1 with Forge 47.4.0 and Java 17. The first start until "Done" took just under four minutes (236 seconds), and further starts were reproducibly between 227 and 236 seconds.
We joined with a real game client the same evening: the world loaded with terrain, minimap and all mods, with no spawn in the void. From the main menu into the game, the client needed a good minute and a half. So be patient on the first load with your fellow players, too.
In its user_jvm_args.txt, the pack sets the Java option AlwaysPreTouch and, with no players, kept over 9 GiB of memory in use on our side, even though Java actually used only just under 3 GB of it. Our installation removes the fixed limits -Xms4G and -Xmx8G from the same file so that the booked 10 GB reach Java in full.

Why ATM9 Gets 10 GB
All the Mods 9 used just over 9 GiB on our test server at idle, because Java touches the reserved memory immediately. Actually used was just under 3 GB; the rest is a buffer that factories, dimensions and multiple players will fill later. 10 GB give this buffer room. A measurement under player load is still pending.

Joined with a Real Client
Loaded on September 26 with terrain, minimap and mods. We did not measure player load in the process.
1.5 GB of Storage Space
That is how much the server took up after the first start. The world grows with every explored dimension.
A successful installation, startup or join test applies only to the tested version and does not demonstrate stable operation under every player load.

Frequently asked questions
Does the button use the matching configuration?
Yes. The wizard preselects the matching loader; modpack pages also load only the verified featured pack.
Can I change version and RAM later?
Yes. Always check compatibility and create a backup before changing versions.
Can I play ATM9 on the free server?
No. At idle, ATM9 uses more than four times as much memory as the free server with 2 GB has. It can be ordered as a paid server with 10 GB, and you can see the price in the configurator before paying.
ATM9 or ATM10?
ATM9 runs on Forge and Minecraft 1.20.1, ATM10 on NeoForge and 1.21.1. Both are large kitchen-sink packs with similar memory requirements. The deciding factor is usually whether your favorite mods already exist for 1.21.1 and which version your fellow players have already installed.
What do fellow players need?
Minecraft Java Edition and All the Mods 9 in the server's version, most easily via the CurseForge app. The first load takes over a minute even on fast computers. Bedrock players cannot join.
Is there chunk protection and homes?
Yes, the pack includes FTB Chunks, FTB Essentials and FTB Ultimine; their defaults for new worlds are in the defaultconfigs folder. For waystones, the Waystones configuration uses the biome style with a frequency of 25.
