What is All The Mods 9?

All The Mods 9 (ATM9) is one of the most popular and feature-complete modpacks in Minecraft history. Built for Minecraft 1.20.1 on Forge, ATM9 packs over 400 mods spanning technology, magic, exploration, and quality-of-life improvements into a single massive experience with over 13 million downloads on CurseForge. The tech side of ATM9 is stacked. Mekanism handles ore processing and power generation, Create brings mechanical automation and contraptions (updated to Create 6.0 in recent versions), Applied Energistics 2 and Refined Storage offer competing digital storage solutions, and the Thermal Series adds industrial machinery and energy systems. Tinkers' Construct lets you forge custom tools, while Immersive Engineering and EnderIO round out the engineering options. Magic is equally well-represented with Ars Nouveau for spell crafting, Botania for natural magic, Blood Magic for darker rituals, and Occultism for demon summoning and logistics. Iron's Spells and Spellbooks adds RPG-style combat magic for players who want a more action-oriented approach. Exploration mods open up entirely new dimensions to conquer. The Aether, Twilight Forest, Blue Skies, and Ad Astra (space exploration) each offer unique biomes, bosses, and progression systems. The custom dimension "The Other" adds ATM-exclusive content you won't find anywhere else. The ultimate goal for most ATM9 players is crafting the ATM Star - an endgame trophy that requires resources from nearly every major mod in the pack. The final craft uses 55 of Create's Mechanical Crafters arranged in a star shape, consuming materials equivalent to roughly 10,935 nether stars. Completing it unlocks creative items and represents true mastery of the pack. ATM9 is the stable, mature choice in the ATM series. While ATM10 runs on newer Minecraft 1.21.1, ATM9's mod ecosystem on 1.20.1 is far more established, with more mods available and years of community-driven bug fixes. To host ATM9 properly, you need a server that can handle 400+ mods, heavy tile entity counts from tech builds, and chunk generation across multiple dimensions.

Why ATM9 Needs Good Hosting

ATM9 is one of the most resource-demanding modpacks available. With 400+ mods running simultaneously and some of the heaviest tech mods in existence, your ATM9 server needs serious hardware to deliver smooth gameplay. World Generation - ATM9 adds multiple custom dimensions (The Aether, Twilight Forest, Blue Skies, Ad Astra, The Other) on top of heavily modified overworld generation. Exploring new chunks triggers dozens of worldgen mods at once. Budget hosts with oversold nodes will cause massive lag spikes or even server timeouts when players explore with jetpacks. Tile Entity Load - Mekanism multiblocks, AE2 storage networks, and Thermal machinery create enormous tile entity counts that stay loaded in memory. A single Mekanism fission setup with structural glass can tank TPS on an underpowered server, even when the chunks aren't actively loaded by a player. Automation Scaling - As players progress through the questbook, automated systems from Create, Mekanism, and AE2 compound rapidly. What runs fine on day one can bring a weak server to its knees by week three when multiple players have full factory setups running 24/7.

Why Self-Hosting Your ATM9 Server Fails

Many players try hosting ATM9 on their home PC or a cheap VPS. Here's how that typically goes:

Week 1

Everything seems fine

Fresh world, minimal automation, few explored chunks. The server runs smoothly and you wonder why anyone pays for hosting. Players start questing and gathering resources.

Week 3

Tech builds start hitting

Players build their first Mekanism ore processing chains and Create factories. Someone explores The Aether and Twilight Forest, generating thousands of new chunks. You notice lag spikes during exploration and occasional server timeouts.

Week 6

Tile entities destroy TPS

Multiple AE2 networks running, Mekanism multiblocks across several bases, entity farms producing items 24/7. The world file exceeds 5GB. TPS drops below 15, block lag makes the game unplayable. Players start leaving.

Dedicated ATM9 hosting on proper hardware solves this from day one. Our Ryzen 9 7950X3D processors maintain 20 TPS even with mature worlds and heavy automation - because that's what 96MB of L3 cache is designed for.

ATM9 Technical Details
