All the Mods 8 drops roughly 380 mods into one 1.19.2 Forge world and lets your group decide what to do with them. Here is what it takes to run one properly.

All the Mods 8 is a kitchen-sink pack from the ATM Team: instead of curating a small set of mods around one theme, it throws roughly 380 of them into a single 1.19.2 Forge world and trusts you to find your own direction. Tech, magic, storage, farming, exploration and building mods all sit side by side, which is why the pack has passed nine million downloads on CurseForge and still fills servers years after release.
That breadth is the appeal and the catch. Nobody finishes ATM8 alone in a weekend, and no two players take the same route through it. On a server with friends it works best when people specialise — one builds the power grid, another handles automation, another goes off exploring for the resources everyone needs.
The opening hour looks close to vanilla: punch trees, build a shelter, find iron. Within a few in-game days that changes completely. You pick a tech mod or a magic mod as your entry point, and every system you touch pulls in another one — power needs ore processing, ore processing needs automation, automation needs storage, storage needs more power.
The quest book is the thread that holds it together. It is not a linear campaign; it is a map of what the pack contains, with rewards that nudge you toward mods you would otherwise never open. Most groups use it as a shared checklist rather than a rulebook.
ATM8 runs on Minecraft 1.19.2 with Forge. The pack is no longer actively updated, and for a server that is good news: the version is frozen, so your world will not break under you when a new build lands. What matters is that everyone connects with the exact same pack version as the server. A client on a newer ATM8 build than the server will be rejected at the door, and that single mismatch is behind most "why can't I join" messages in group chats.
If your group wants a newer Minecraft version, that means a different pack in the series rather than an update to this one — worth deciding before you build anything you care about.
Kitchen-sink packs are heavy, and ATM8 is one of the heavier ones. For two or three players, 6 GB is the sensible floor. For a normal group of four to six, 8 GB gives you room to build without watching the tick counter. Past that — six to ten players, several loaded bases, quarries and mob farms running while people are offline — 10 to 12 GB is the honest number.
RAM is only half of it. Modded Minecraft leans hard on single-thread CPU performance, so a fast core matters more than a lot of slow ones. The usual cause of lag on an ATM8 server is not a small memory pool but too many chunks kept loaded by too many automated systems at once.
Mekanism is where most groups end up for power and ore processing. Its multiplier chain turns one ore into several ingots, which changes the economics of every other mod in the pack, and its machines scale from a single furnace replacement to a factory floor. It is also the mod most likely to eat your server's tick budget if you leave everything running while nobody is online.
By month one an ATM8 base has more item types than chests can handle. Applied Energistics 2 turns that pile into a searchable digital system with autocrafting on top, and once a group has it running, most of the day-to-day friction of the pack disappears. Build it before your base becomes a wall of barrels, not after.
The pack's endgame item is the ATM Star, and its recipe is deliberately spread across the mods in the pack. Chasing it is the closest thing ATM8 has to a finish line: to craft one you have to touch systems you would otherwise skip, which is exactly the point. On a server it works well as a group project rather than a solo grind.
In most cases it is chunk loading. Every quarry, mob farm and always-on machine keeps its chunk awake, and a server with six players each running three of them is doing far more work than the player count suggests. If your server starts stuttering, the fix is usually to consolidate bases and switch off systems nobody is using, not to add more RAM.
