Frequently Asked Questions

Class Gem: Core server crashes on startup – what to do?

Most common cause: wrong forge version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (1.20.1). You can switch loaders with one click in the panel.

Is Class Gem: Core compatible with forge?

Class Gem: Core officially supports forge for Minecraft 1.20.1. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with Class Gem: Core – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Class Gem: Core consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
