Running a modded Minecraft server is awesome - but it also requires more resources than a normal vanilla or plugin server.
This guide will help you choose the right amount of RAM for your modpack so your server stays smooth and stable.
Why Modded Servers Need More RAM
Mods add extra content like:
New dimensions and biomes
Machines and automation
Custom mobs and world generation
Large item and block libraries
All of this increases memory usage compared to vanilla Minecraft.
General RAM Recommendations
Here’s a good starting point for most servers:
Light Modpacks (Small Packs)
4–8 GB RAM
Simple modpacks
Small friend groups
Minimal world generation mods
Medium Modpacks (Most Popular Packs)
8–12 GB RAM
Packs like Better Minecraft
More active players
Larger worlds
Heavy Modpacks (Large Packs)
12–16+ GB RAM
Big tech/magic packs
Lots of chunk loading
Servers with many players online
KiwiNode Plans
We offer three standard plans that you can order. For modded servers, we recommend using either the Minecraft Medium or Minecraft Large plan for the best performance. If you need more power than this for the most demanding modpacks, open a support ticket and our team will assist you in ordering a custom service.
Signs You Need More RAM
You may need an upgrade if you notice:
Frequent server crashes
“Out of Memory” errors
Long loading or restart times
Players experiencing lag spikes
Upgrading is Easy
