Why do my ATM10 farms stop when nobody is online?

Because FTB Chunks ships with `force_load_mode: DEFAULT`, which only keeps force-loaded chunks ticking while a member of that team is online and holds the `ftbchunks.chunk_load_offline` permission. Nobody has it by default. Set `force_load_mode: ALWAYS` in the `force_loading` group of `config/ftbchunks-server.snbt` and restart, or grant the permission through FTB Ranks instead.

How much RAM does an All the Mods 10 server need?

Start at 8 GB for around six players, which is the bottom of ATM's own 8 to 12 GB guidance. Large automation setups and lots of loaded chunks push it up. Before adding memory, run `/spark profiler --timeout 180` and read the result, because on a pack this size most of what feels like a RAM problem turns out to be one mod's ticking blocks or a runaway mob farm.

How do I pregenerate chunks on ATM10?

ATM10 does not include Chunky, on purpose. NeoForge has the tool built in: run `/neoforge generate start ~ ~ ~ 500` from inside the dimension you want generated, where the last number is a radius in chunks, up to 2500. Repeat it in the Nether, the End and any modded dimension you care about. Run it before you invite the group, since it is heavy while it works.

Can I raise the chunk claim limit for a player?

On a world that already exists, editing the config will not do it: FTB Chunks stores per-player limits in the world data and the file gets overwritten on restart. Use `/ftbchunks admin extra_claim_chunks set 1000` and `/ftbchunks admin extra_force_load_chunks set 100` from the console instead. The config file only sets the defaults for players who have not been given an override.

Can I update ATM10 without losing my world?

Point releases are usually additive, and the panel's update flow keeps your world and can back it up first. The risk is not the Minecraft version, it is mods being removed: if a build drops a mod, everything you built from it disappears from the save. Read the changelog for the version you are jumping to, take a backup, and tell your players to update their client at the same time.

Is ATM10 too heavy for a small group?

Not for four to six people on 8 GB, which is the common case. If your group is two or three and mostly casual, the ATM Team also publish ATM10 Lite, which is the same idea with a smaller mod list and lower requirements. Do not confuse either with ATM10 To The Sky, which is the skyblock version, or with All the Mods 11, which is a separate pack.

All the Mods 10 Server Hosting

by ATMTeam

NeoForgeMinecraft 1.21.1Java 21

How install works

One-click install from the Modpacks tab once your server is ready

Recommended RAM: 8 GB
Latest build: v8.1Aug 2026
Mod loader: NeoForge1.21.1
Downloads: 21.6MCurseForge

All the Mods 10 is the ATM Team's current kitchen-sink pack, and for most groups it is the default answer to "what should we run this year". It puts around 500 mods on NeoForge 1.21.1 and then does the thing that separates ATM from a random mod dump: an FTB Quests questline ties them together, so you always have a next objective even with Mekanism, Applied Energistics 2, Create, Ars Nouveau, Botania and Minecolonies all installed at once.

The spine of progression is the ATM ore ladder. Allthemodium, Vibranium and Unobtainium gate the late game, and everything funnels toward crafting the ATM Star. Build 8.1 added Ad Astra, so space is now part of that arc.

What this means for a server is a long, slow-burning world. Nobody finishes ATM10 in a weekend, people specialize, and the save tends to live for months. If your group wants a shared base where one person does nuclear power and another does bees, this is the pack. If you want a guided story with an ending, Prominence II fits better, and if your plan is small, ATM10 Lite exists for exactly that reason.

Hosting All the Mods 10

Why we size it at 8 GB

ATM's own guidance for their packs is 8 to 12 GB, and 8 GB is where a group of around six should start. The pack already ships the memory fixes people normally bolt on, FerriteCore, ModernFix and AllTheLeaks, plus spark for profiling, so extra RAM is not a substitute for finding the actual problem. When TPS drops, take a profile rather than buying memory:

/spark profiler --timeout 180
/spark tps

The force-loading trap every ATM server hits

This is the ticket we see most. Someone claims chunks with FTB Chunks, force-loads their base, logs off, and comes back to farms and bees that produced nothing overnight. That is the default behavior, not a bug. In config/ftbchunks-server.snbt the force_loading group contains:

force_loading {
    force_load_mode: DEFAULT
    max_force_loaded_chunks: 25
}

DEFAULT only keeps chunks loaded while someone on the team has the ftbchunks.chunk_load_offline rank permission, which nobody has out of the box. Set force_load_mode: ALWAYS if you want machines running while the server is empty. Note the keys are nested inside claiming and force_loading groups, and editing the file on a world that already exists will not raise a player's limits. For that, use the admin command:

/ftbchunks admin extra_force_load_chunks <player> set 100
/ftbchunks admin extra_claim_chunks <player> set 1000

Pregenerate with the built-in command

ATM10 deliberately ships no Chunky, because NeoForge has its own generator. Run it from inside each dimension you want covered, since it uses your current one:

/neoforge generate start ~ ~ ~ 500

The radius is in chunks and caps at 2500.

Java 21, updates and backups

1.21.1 needs Java 21 and the installer selects it for you. Point releases are additive in practice, but read the changelog before you jump: a build that removes a mod removes its blocks from your world too. Back up first, and keep backups frequent regardless, because force-loaded chunks have been reported coming back empty after a hard crash.

Force loading

Farms stop when you log off

FTB Chunks defaults to loading claims only while a team member is online. Set force_load_mode to ALWAYS.

RAM

8 GB is the ATM baseline

ATM recommends 8 to 12 GB for their packs. Profile with spark before assuming more memory is the fix.

Pregen

No Chunky needed

ATM10 leaves pregeneration to NeoForge's own generate command, run once per dimension from inside it.
