WHY MEKANISM ON A SERVER

Mekanism is the industrial half of modded Minecraft: 5x ore processing, gas networks, digital miners, and a fission reactor that will absolutely irradiate your base if someone gets careless. On a shared server that danger is the fun — infrastructure becomes a group project with real stakes.

Machine-heavy bases mean sustained tick load, not spikes. Guaranteed CPU allocation (not oversold shares) is what keeps a mature Mekanism base at 20 TPS.

From zero to playing in three steps

STEP 1

Create the server

The button below pins NeoForge and stages Mekanism. You choose the name and plan.

STEP 2

First boot

Libraries resolve automatically. Watch the console; a modded first start takes about a minute.

STEP 3

Join and industrialize

Install Mekanism client-side, join your address, and start your ore lines. Add Mekanism Generators from the Mods tab when you're ready for power.

Questions, answered.

How much RAM does a Mekanism server need?+

4 GB handles Mekanism and its add-ons (Generators, Tools) for a small group. Kitchen-sink builds around it push toward 6–8 GB — upgrade in one click when you feel it.

Does Mekanism include power generation?+

Base Mekanism has the machines; power sources beyond the basics live in the official Mekanism Generators add-on. It's a one-click install from your server's Mods tab, dependencies included.

Can a fission reactor really melt down in multiplayer?+

Yes — meltdowns damage the world around the reactor and irradiate players. Chunks stay loaded while any player is near, so build your reactor room away from spawn and put someone responsible on the control rods.
