How Much RAM Does a Project Architect 2 Server Need?
Project Architect 2 is a Forge 1.20.1 Project Architect 2 pack page favorite for pure building and decoration — Macaw's series, Supplementaries, and Chipped stacked together with no tech or magic progression at all. That changes where the RAM goes: it's spent on a huge block and item registry and on keeping elaborate builds loaded, not on simulating machines or spells. Finnish players: Minecraft-palvelin hosting is our native-language page. German players: Minecraft-Server mieten covers the same hosting auf Deutsch. Svenska spelare: Hyra Minecraft-server täcker samma hosting på svenska.
3 GB
Bare minimum for a solo builder testing the pack. The block and item registry from Macaw's, Supplementaries, and Chipped still has to fully load at this size, so boots are slower and there's no headroom for a second player.
5 GB
The best starting point for most Project Architect 2 servers. This matches the pack's own recommended floor and gives the building-mod registry enough room to load cleanly while leaving space for a small group placing blocks.
7 GB
Safer for a mid-size active group building together. Since the pack has no tech or magic progression to spread load across, the extra headroom here goes toward more loaded chunks and more players placing blocks at once rather than machine simulation.
10 GB
For 10+ players or a long-running world with large, elaborate builds. Big decorative structures from this pack's furniture and block mods keep more chunks resident in memory than a typical survival world of the same player count.
