About this Modpack

Description

A collection of Fabric-based mods that work on most vanilla servers. Made for both vastly improving performance and enhancing the experience with quality of life tweaks.

Made really just for my own convenience, and as such mods are included based on my own preferences. This modpack has been tested thoroughly, and I can verify they all work together.

50+ mods, you can find most (if not all) mods from both Fabulously Optimised and Lambda's Optifine Parity list, as well as more included for my benefit.

A zip download can be found at Moddermore.

Every version release has been tested to work.

Frequently Asked Questions

oshpack 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 oshpack 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 oshpack without conflicts?

Yes, but check compatibility: only use mods for the same loader (fabric) and same Minecraft version (1.21.11). 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.

oshpack 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.
