How Much RAM Does a Crackpack 3 Server Need?
Crackpack 3 packs a huge number of Forge 1.12.2 mods together without heavy curation, so its memory needs run higher than a tightly tuned pack of similar size — see the Crackpack 3 pack page for the full mod list and details. Finnish players: Minecraft-palvelin hosting is our native-language page. German players: Minecraft-Server mieten covers the same hosting auf Deutsch. Svenska spelare: Hyra Minecraft-server täcker samma hosting på svenska.
5 GB
Bare minimum for solo play or a tiny group of 1-2 players. Crackpack 3's uncurated mod list leaves little headroom below this, and you'll want to keep an eye on memory during long sessions.
7 GB
The best starting point for most Crackpack 3 servers. This matches the pack's own recommended floor and gives the huge, uncurated mod list enough room to load and run without constant garbage collection pauses.
10 GB
Safer for a mid-size active group of 4-8 players. More simultaneous chunk loading and mod interactions mean more memory pressure than a curated, quest-based pack of similar mod count.
14 GB
Recommended for 10+ players or a long-running world. Crackpack 3's emergent, exploration-driven worlds tend to sprawl further over time than tightly scripted packs, which adds up in loaded-chunk and entity memory.
