About this Modpack

Iron Frost

Iron Frost Tittle Card
Survive the cold in the Iron Frost. Here in the cold you can hire and manage citizens to build your city and with the power of steam you might just conquer the snow.

This is built around 3 core mods.
Create for its steampunk automation
Minecolonies to build and manage your own city
Terralith with some added config mods to turn everything to snow

These together with many other mod additions create a snowy winter wonderland to explore and survive in. This is more of a laid back experience without harsh weather or overly challenging mobs creating a unique experience for a casual cold play through.

Frequently Asked Questions

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

Most common causes: insufficient RAM or wrong forge loader. Check latest.log for "OutOfMemoryError" → increase RAM to at least 8 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 Iron Frost server really need?

Minimum 6 GB, recommended 8 GB for stable performance. per 5 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 €7.800000000000001/month).

Can I add custom mods to Iron Frost without conflicts?

Yes, but check compatibility: only use mods for the same loader (forge) 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.

Iron Frost server lagging – performance tips

1) Increase RAM to 8 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.
