What are the system requirements to run ATM9 smoothly?

We recommend 10–12 GB RAM for the server and at least 6 GB allocated on the client. A modern 4-core CPU is also advised.

How do I install ATM9 on my Minecraft client?

Use the CurseForge launcher or Prism Launcher to search for "All the Mods 9" and install it. Make sure you are using Minecraft 1.21.1 and NeoForge.

Can I modify or add extra mods to ATM9?

Yes, ATM9 is fully customizable. Just make sure both client and server have matching mod lists.

What makes the ATM Star unique?

The ATM Star is a complex item requiring inputs from across the entire modpack — it’s a true endgame achievement.

Is ATM9 optimized for performance?

Yes. It includes mods like Rubidium, Oculus, and FerriteCore to improve client FPS and memory usage.

What specs do I need for ATM9 Server Hosting?

ATM9 is heavy: start with high-clock CPUs and 8–10 GB RAM (increase for more players or automation). Godlike Server Hosting offers one-click ATM9 installs, NVMe speed, backups with one-click restore, DDoS protection, and SFTP/FTP access for configs. Scale RAM/slots anytime from the panel.

All the Mods 9 (ATM9) is a large “kitchen sink” modpack for Minecraft 1.20.1 on Forge, built for long-running co-op worlds. It packs 400+ mods, countless quests, and a proper endgame—can you craft the ATM Star, and do you dare take on the Gregstar?

Quick facts

Minecraft: 1.20.1
Mod loader: Forge
Scale: 400+ mods • quest-heavy • endgame
Playstyles: Tech • Magic • Building • Exploration
Endgame goals: ATM Star • Gregstar

What gameplay feels like

Quest-guided progression: follow the quest book to move from early survival into power, storage, and automation.
Scale your base: build farms and factories that grow with your world and player count.
Explore for progression: structures, dimensions, and loot stay relevant as you push deeper into the pack.
Real endgame: long crafting chains lead to the ATM Star and Gregstar milestones.

What makes ATM9 different

A “best-of” mix: big-name staples plus newer/lesser-known mods, without forcing one “correct” route.
Built for stability: the pack focuses on being playable for long worlds while still adding depth and variety.
Designed for SMPs: players can specialize (tech/magic/build/explore) while sharing one roadmap through quests.

If you want a modded server that stays engaging for weeks (or months), ATM9 is built for long progression rather than a quick weekend run.

What are the requirements to host an ATM9 server?

ATM9 is a heavy modpack. Start with 10–12GB RAM for small groups and use 14–16GB for 5+ players or automation-heavy worlds. Larger or long-running worlds may need more.

Which Minecraft version and mod loader does ATM9 use?

ATM9 runs on Minecraft 1.20.1 and requires the Forge mod loader.

Which Java version is required for ATM9?

Use Java 17 or newer. Using the wrong Java version is a common cause of launch errors and crashes.

Do players need to install ATM9 to join the server?

Yes. Every player must install the same ATM9 client modpack version as the server, otherwise they’ll get mismatched mods / connection errors.

How do I update ATM9 safely?

Use this flow: backup → update the server pack → update all clients to the same version → test login before opening the server to everyone.

What are the ATM Star and Gregstar?

They’re the main endgame milestones in ATM9 - the ATM Star is the big endgame craft, and Gregstar is an even higher-end progression goal.

How do players install ATM9 on PC?

Install ATM9 through a launcher that supports the pack (e.g., CurseForge), then make sure the exact modpack version matches the server before joining.

I can’t join (mismatched mods / missing mods). What should I do?

Match Minecraft 1.20.1, Forge, and the ATM9 modpack version exactly. If the server updated, all players must update too.

Is ATM9 stable or frequently updated?

ATM9 is actively maintained. For long-running servers, it’s best to pin a stable pack version and update intentionally (not automatically).

My server is lagging, what are the biggest fixes?

Most lag comes from chunk generation, entity buildup, and heavy automation. Start with enough RAM headroom, keep view distance reasonable, and reduce excessive mobs/items/machines; for long-term servers, consider pre-generating chunks.
