How Much RAM Does a Crucial 2 - The Refresh Update Server Need?
Crucial 2 - The Refresh Update is a polished Forge 1.16.5 kitchen-sink combining tech, magic, and exploration mods — see the full breakdown on the Crucial 2 pack page. Here's how much RAM it actually needs at different player counts. 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
The bare minimum for solo play or a tiny two-player world. It can boot the pack's Forge 1.16.5 mod list, but tech chains like Mekanism and magic systems like Botania will compete for headroom once a base gets going, so expect occasional slowdowns.
7 GB
The best starting point for most Crucial 2 servers — this matches the pack's own recommended allocation for running its tech, magic, and exploration mods together, and is the floor we'd actually recommend rather than the minimum that merely boots.
9 GB
A safer choice for a mid-size, active group running multiple Mekanism factory setups, active Biomes O' Plenty exploration, and several players online at once without memory pressure building up over a session.
12 GB
Built for 10+ concurrent players or a long-running world with a large explored map and heavy tech/magic infrastructure, where chunk and entity load stay elevated for hours at a time.
