How Much RAM Does a Jaffa Factory 2 (Replica) Server Need?
Jaffa Factory 2 (Replica) recreates the exact mod list and configuration from Yogscast's Forge 1.20.1 series, which means its RAM needs track the series itself rather than a generic factory pack. Check the Jaffa Factory 2 (Replica) pack page for the full mod list, then use the tiers below to pick a starting plan. Finnish players: Minecraft-palvelin hosting is our native-language page.

3 GB
Bare minimum for a solo world or testing the pack before you commit. With this many mods loaded on Forge 1.20.1, expect long chunk-generation pauses and tight memory once a few factory lines are running.
5 GB
Best starting point for most Jaffa Factory 2 (Replica) servers. This matches the pack's own recommended RAM floor and comfortably covers a small group recreating the Yogscast series together.
7 GB
Safer for a mid-size, active group running several factory lines in parallel, or if you're also keeping chunks loaded further out than default for base-building.
10 GB
For 10+ players or a long-running world with a large explored map, heavy automation across multiple bases, and extended uptime between restarts.
