Pack setup

How should I set up Optimized Core for players and a server?

Use Optimized Core Legacy MC 1.8.9 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.

Dedicated server setup Match Optimized Core Legacy MC 1.8.9
Pack loader Forge 11.15.1.2318

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 8
Client only 5
Server only 1
Not labelled 2

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 Optimized Core?

Optimized Core Legacy MC 1.8.9 on 1.8.9 Forge. The pack contents and setup notes below stay tied to that release.

8 mods in this pack file

The selected pack release is Optimized Core Legacy MC 1.8.9. That file is for Minecraft 1.8.9 with Forge 11.15.1.2318. It contains 8 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.
