All the Mods 9 - ATM9

All the Mods 9 (ATM9) is a large-scale, late-game-focused modpack for Minecraft 1.20.1 on Forge, built to support long-running worlds with lots to do: progression, automation, exploration, and a clear endgame chase. With 400+ mods, it’s the kind of pack that shines when it’s online all the time—ready for friends to hop in, build big, and keep progress moving.

• Built for big packs: Our hardware is tuned for the heavier tick-load and chunk activity ATM9 is known for.
• Fast, stable CPU performance: Hybrid VPS design means consistently strong single-thread performance where Minecraft needs it most.
• One-click installs and updates: Get the server running quickly, with updates designed to preserve your configuration changes.
• Practical admin tooling: Built-in diagnostics help pinpoint lag sources (entities, chunks, TPS drops) before they ruin a session.
• Modded-community experience: Over 13 years hosting large modded servers means fewer surprises when your world gets serious.

All the Mods 9 (ATM9) — Modpack Overview

ATM9 is a “kitchen-sink” style pack: it isn’t one single theme, but a curated collection designed to support many playstyles at once. On a server, that usually means different players can progress differently—some exploring and building, others automating and scaling production—without the pack feeling like it runs out of runway.

What makes ATM9 especially server-friendly is the mix of breadth (lots of mods and systems) and a structured endgame goal. That combination tends to keep communities engaged for weeks or months, which is exactly where a reliable host matters.

What server owners typically like about ATM-style packs

• Players can specialize without blocking each other’s progress.
• Plenty of “always something to do” momentum for groups.
• Longer world lifespan than smaller, narrowly focused packs.

Why CreeperHost is a strong fit for ATM9

Before you even touch config files, the biggest difference-maker for a pack like ATM9 is stable CPU performance under load. Modded servers don’t just need “more RAM”—they need consistent tick performance when farms, machines, mob activity, and multiple dimensions are all happening at once.

CreeperHost runs modded Minecraft on Ryzen, EPYC, and Intel Ultra-based liquid-cooled servers, backed by a hybrid VPS platform designed for dependable, native CPU performance. For ATM9, that translates into smoother busy-hours and fewer “it was fine yesterday” performance swings.

We also focus on the operational side of actually running a community server:

• One-click modpack installation and updates that are designed to preserve your config changes (so you can tune without fear of losing work).
• GUI-based mod/config management for quicker iteration when you’re balancing gameplay or stability.
• DDoS protection and reliability to keep public servers online when attention spikes.

Hosting Considerations for All the Mods 9 (ATM9)

ATM9 is a large pack, and large packs follow predictable patterns on servers. Planning for them up front makes the experience dramatically smoother.

Memory (RAM) expectations

ATM9 generally benefits from generous RAM headroom—not just to boot, but to stay stable as the world grows and more chunks/dimensions get explored. When servers feel “randomly laggy,” it’s often because memory pressure is triggering heavy garbage collection or the server is swapping.

CPU and tick-load patterns

Even with plenty of RAM, most modded slowdowns come from tick-time pressure:

• Large automation setups and always-loaded chunks
• Entity buildup (mob farms, item drops, villagers)
• Exploration spikes (new terrain generation, multiple players flying in different directions)

A strong CPU helps, but good server hygiene matters too—reasonable view distances, sensible chunk-loading, and keeping entity counts under control.

Updates and long-lived worlds

ATM9 servers are often “forever worlds.” That means updates should be handled carefully:

• Take backups before changing versions
• Treat major updates like a planned maintenance window
• Keep configs consistent so performance doesn’t drift over time

Run ATM9 with confidence on CreeperHost

ATM9 is at its best when it’s always available, performant, and easy to maintain—especially once your players hit the stage where bases span chunks and automation never sleeps.

If you’re aiming for a long-running community world, CreeperHost gives you the stable performance foundation, the admin tooling to stay ahead of lag, and the operational reliability that big modpacks demand.
