Ampz is a mod pack built around Minecraft 1.20. It is available both on the Curseforge and on the Technic Launcher. The Ampz modpack consists of various mods that use the Electrodynamics electricity API in addition to several others compatible with it. It intends to be as similar as the original Voltz way back from 1.4.7 as possible.
Bring the world at your knees with missiles, bombs, machinery, and all of the creations you can figure with your mind!

Frequently Asked Questions
Ampz 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 Ampz 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 €12/month).
Can I add custom mods to Ampz without conflicts?
Yes, but check compatibility: only use mods for the same loader (forge) and same Minecraft version (1.20.1). 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.
Ampz 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.
