Play the All The Mods 10 Minecraft Modpack
All The Mods 10 (ATM10) is a large Minecraft modpack with hundreds of mods, built on NeoForge for Minecraft 1.21.1. The CurseForge app downloads and sets it up for you, so there is nothing to copy by hand. You need a paid copy of Minecraft: Java Edition and a PC with at least 16 GB of RAM — the pack is heavy.
Install the CurseForge app
Download the CurseForge app from its official site and run the installer.
When it opens, pick Minecraft from the list of games. The first time, CurseForge asks where to keep your Minecraft files — the default folder is fine.
Give Minecraft more memory
ATM10 crashes or stutters on the default memory setting. Click the gear icon at the bottom left to open Settings, choose Minecraft, and under Java Settings drag the Allocated Memory slider to between 8192 and 10240 MB (8 to 10 GB).
Do not go above about 12 GB — more memory makes the game stutter rather than helping.
Install ATM10
Go back to Minecraft, click Browse, search for All The Mods 10, and click Install on All the Mods 10 - ATM10. You can also open the pack's page below and install it from there.
The download is a few gigabytes and takes several minutes. The pack moves to My Modpacks when it is done.
Launch the modpack
Open My Modpacks, click ATM10, and click Play. The card should show NeoForge and 1.21.1 — if it shows a different version, the wrong pack was installed.
The Minecraft Launcher opens; sign in with your Microsoft account if asked, then click Play there too. The first start takes several minutes while all the mods load. It can look frozen on the loading screen — leave it.
Join the server
On the Minecraft title screen, click Multiplayer, then Add Server. Enter this in Server Address and click Done:
from-about.gl.joinmc.link
The server appears in the list. Click it and click Join Server.
The game crashes while loading — Memory is set too low. Redo step 2 and make sure the slider is at 8 GB or more.
The server says your mods or version do not match — The server and your pack are on different ATM10 versions. In My Modpacks, click the three dots on ATM10 and update it, or ask on the server which version to use.
The server shows as offline — The server is not always running. Try again later, or ask in the Discord.
ATM10 is now installed and saved in My Modpacks. Next time, open CurseForge, click Play on ATM10, and the server stays in your multiplayer list.
