How Much RAM Does a GT New Horizons Server Need? (6GB+ Guide)
Figuring out RAM for GT New Horizons starts with separating its old Minecraft version from its actual complexity — see the GT New Horizons pack page for the full details, but the short version is that the 1.7.10 base keeps the floor lower than a modern pack while the GregTech recipe tree still demands real headroom.

4 GB
Enough for a quick solo test of the early GregTech chain, but tight once ore processing and multiple machine lines are running — the recipe complexity catches up with you faster than the RAM number suggests.
6 GB
The realistic floor for GT New Horizons. The 1.7.10 base keeps this lower than a modern kitchen-sink pack would need, while still covering the recipe tree's memory footprint for a small group.
8 GB
A safer pick once a few players are running separate GregTech production lines at the same time — more headroom for concurrent machine processing and ore-dictionary lookups.
12 GB
Worth it for a long-running server with 10+ players and months of accumulated base-building, factories, and explored terrain — the kind of world GTNH is actually designed around.
