About this Modpack

What is Ion?

Ion is a modpack with 18 of the essential optimization mods for Minecraft. Simply put, this helps your game run smoother, quicker, and more reliably without changing any part of the normal vanilla experience.

Why would I need this?

Ion can extremely benefit those with lower-spec computers or those who want to run multiple things at once (such as Minecraft and editing software at once) without Minecraft being too much of a resource hog.

Variations:

Nvidia - Only works with Nvidia GPUs and does not have shader support
Shaders - (Recommended) Works with Nvidia, Intel, and AMD GPUs and has shader support

Important to note:

Ion is not allowed in speedrunning
The mods in Ion were not created by me, so if you enjoy Ion, go show the creators of the individual mods some love, their mods are listed at the bottom

That is all! Enjoy Minecraft more optimized than ever before!

Frequently Asked Questions

Ion server crashes or won't start – what to do?

Most common causes: insufficient RAM or wrong fabric loader. Check latest.log for "OutOfMemoryError" → increase RAM to at least 6 GB. For "Mixin" or "ClassNotFoundException" errors: modpack version and loader don't match. With Mado Hosting, loader and Minecraft version are auto-configured on modpack install – preventing most startup issues.

How much RAM does a Ion server really need?

Minimum 4 GB, recommended 6 GB for stable performance. per 8 players. Important: Minecraft modpacks need more RAM than vanilla – plan extra per additional player. With Mado Hosting, you can scale RAM up live at any time without data loss (from €8/month).

Can I add custom mods to Ion without conflicts?

Yes, but check compatibility: only use mods for the same loader (fabric) and same Minecraft version (1.21.1). Common issues: ID conflicts with recipe mods and incompatible coremod versions. The Mado dashboard mod browser only shows compatible mods and warns about known conflicts.

Ion server lagging – performance tips

1) Increase RAM to 6 GB+. 2) Reduce server view-distance to 8 (server.properties). 3) Pre-generate chunks with the "Chunky" plugin. 4) Use /spark profiler to check which mods consume the most tick time. With Mado Hosting, all servers run on NVMe SSDs with dedicated CPU cores – eliminating hardware as a bottleneck.
