If you don't know how to allocate more RAM to Minecraft, here is a good tutorial.
You can find the modlist here. It includes all the mods + links to the modrinth pages, the authors, the license, mod description, Mod download count and the project ID on modrinth. It isn't here because it's too long.
This list is updated with a script I created that uses the output of the ferium list -v command and converts it into a nice markdown table. You can find the script here. Ferium is a CLI tool to help manage your mods
- You can find server instructions here.
- The mod list is available on GitHub.
- If you have any problems, check the GitHub repository. If you can't find a solution there, message me on Discord: @orbitalexplorer or create an issue on the GitHub issues page.

Frequently Asked Questions
Tachyon 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 Tachyon 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 Tachyon without conflicts?
Yes, but check compatibility: only use mods for the same loader (fabric) and same Minecraft version (1.20.4). 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.
Tachyon 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.
