Quick answer

Which Optium (Low-End) release should I use?

Updated 1 year ago

Loader Fabric 0.16.14

Optium (Low-End) 1.0.0 is a complete pack release for 1.21.8 with Fabric 0.16.14. Install it as its own launcher instance. If the creator publishes a separate server file, make sure it names this exact pack release. 15 mods in this pack file.

Pack setup

How should I set up Optium (Low-End) for players and a server?

Use Optium (Low-End) 1.0.0 as the pack version. Install the pack as its own launcher instance. The creator’s listing does not name a separate server file, so check the release notes before setting up a dedicated server. Do not upload the ordinary client folder blindly.

Client instance Install Optium (Low-End) 1.0.0
Dedicated server setup Match Optium (Low-End) 1.0.0
Pack loader Fabric 0.16.14

A pack is a matched client and server setup, not one mod with an install-side label. Keep its release, loader, manifest and overrides together.

Plan the server requirements Read the Minecraft installation guide
Referenced mods 15
Client only 10
Server only 0
Not labelled 5

These numbers come from the pack file you chose. “Not labelled” means we don’t know which side it belongs on—not that it is safe everywhere. The file count is not a RAM estimate.

What are the server requirements for Optium (Low-End)?

Optium (Low-End) 1.0.0. Change the pack release and its contents or setup may change too.

15 mods in this pack file

The selected pack release is Optium (Low-End) 1.0.0. That file is for Minecraft 1.21.8 with Fabric 0.16.14. It contains 15 mod projects. The creator’s listing does not name a separate server file. Check their notes before using one, and do not upload an ordinary client folder or rebuild the pack mod by mod. A file count cannot tell us the right RAM, CPU or storage; size the server for the players and world you actually run.
