How Much RAM Does a Star Technology Server Need?
Star Technology brings GregTech CE: Unofficial — the modern continuation of the legendary GregTech mod — into a skyblock format on Forge 1.20.1, and its ore-processing and multi-block-machine systems are heavier on RAM than most packs. See the full details on the Star Technology pack page. 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.
6 GB
Bare minimum. Workable for solo or a tiny early-game group, but GregTech CEu's ore processing and multi-block machines will start to strain this as soon as a few machine lines run at once.
8 GB
The best starting point for most Star Technology servers. This matches the pack's own recommended RAM floor and gives GregTech CEu's machine simulation room to run without choking the rest of the skyblock world.
10 GB
Safer for a mid-size active group once multiple players are running parallel processing chains and the base has grown past a handful of multi-block machines.
12 GB
For 10+ players or a long-running world with a fully built-out GregTech CEu factory — deep processing chains and heavy automation add up over time.
