How Much RAM Does a Tekkit Classic Reloaded Server Need?
Tekkit Classic Reloaded rebuilds the legendary 2012 Tekkit Classic on Forge 1.19.2, and that nostalgia-driven lineup — Industrial Craft 2, BuildCraft, and ComputerCraft — sets the RAM math. See the Tekkit Classic Reloaded pack page for the full mod list. Here's how much RAM to allocate depending on your group size. 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.
3 GB
Bare minimum — fine for a solo world or quick test boot, but Industrial Craft 2 machines and BuildCraft pipe networks will start to strain the server once you're actually building out a base.
5 GB
The best starting point for most servers. This is Tekkit Classic Reloaded's own recommended RAM floor, and it's enough headroom for a small group running IC2 power setups and BuildCraft automation without stutter.
8 GB
Safer for a mid-size active group — multiple players running their own machine chains, quarries, and ComputerCraft turtles at the same time.
12 GB
For 10+ players or a long-running world with a large, built-out power grid, sprawling BuildCraft pipe networks, and years of chunk data accumulating.
