How Much RAM Does a Mekanism: Automation Server Need?
Mekanism: Automation (see the Mekanism: Automation pack page) puts Mekanism itself at the centerpiece of this NeoForge 1.21.1 pack, rather than treating it as one mod among dozens — which is why it sits in a heavier RAM class than Technical Electrical, a separate pack built around general electrical automation instead of Mekanism's specific gas, reactor, and ore processing systems. Here's how much RAM to budget depending on how far you plan to push it. 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.
4 GB
Bare minimum. Workable for solo play or a quick test of the pack, but ore processing, gas systems, and early automation lines will start to strain this tier fast.
6 GB
The best starting point for most servers — this matches the catalog's own recommended RAM floor for Mekanism: Automation and comfortably handles a small group building out their first factory lines.
8 GB
Safer for a mid-size active group running several ore processing chains, gas-burning setups, and multiblock machines side by side.
12 GB
For 10+ players or a long-running world — nuclear reactors, digital miners, and multiple large automated factories running continuously need the extra headroom.
