Why a Minecraft modpack needs 12 GB of RAM
A Minecraft modpack needs 12 GB of RAM because a large pack uses about 8 GB before anyone joins: every mod loads its blocks, items and recipes when the server starts. After that, each player adds roughly 1 GB, because modded chunks are heavier than vanilla chunks. So 12 GB carries a large modpack for about four players, and a lighter pack of about 100 mods for six. The modpack number is also the one people most often get wrong, because the server needs so much memory before anyone plays.
Choosing a 12 GB Minecraft server for a modpack
For a modpack, the processor matters just as much as the RAM. Large modpacks run lots of machines and custom entities, and that work runs on a single core. Performance plans such as Astroworld Standard Performance at €23.95 a month are built for this. The cheapest 12 GB plan is CheapestMinecraftHosting Builder at €9.60, on a shared Ryzen 9 7950X, which is a fast processor even when it is shared.
For 2 to 5 players with a light modpack of about 100 mods on Java in Poland (Warsaw), the finder recommends Astroworld Hosting Standard Performance: 12 GB, AMD Ryzen 9 7950X, DDR5, for €23.95 a month when you pay monthly. As a new customer you pay €9.58 a month for the first 3 months, 60% off. The best plans at the other two hosts are Lodehost Standard at €23.95 and CheapestMinecraftHosting Builder at €9.60.
How many players fit on a 12 GB Minecraft server?
A 12 GB Minecraft server holds about 30 players online on vanilla, 20 with plugins, 14 on a modded server and 4 on a large modpack. The table shows how many players fit on 12 GB of RAM for each kind of server, by the same rule the finder uses. For a modpack, the processor matters as much as these numbers.
| Setup | Players online on 12 GB | What that means |
|---|---|---|
| Vanilla | About 30 | The vanilla server or Paper without plugins |
| Plugins | About 20 | Paper or Purpur with a few plugins |
| Modded | About 14 | Fabric, Forge or NeoForge with mods you pick yourself |
| Modpack | About 4 | A large modpack with around 300 mods |
12 GB for a Minecraft plugin server
A 12 GB Minecraft server is also the next step for a plugin server that has outgrown 8 GB, not only a size for modpacks. Twenty players on Paper with plugins fit comfortably, and so do bigger worlds with a web map, an economy and a few minigames. At that size, keep an eye on the tick rate as well as the memory: twenty players share one main thread, so a fast processor matters. Our page on Minecraft hosting for 20 players covers the plugins and settings that help.
