How Much RAM Does an Antimatter Chemistry Server Need?
Antimatter Chemistry is a chemistry and nuclear physics progression pack on Forge 1.12.2, and its RAM needs sit higher than a plain vanilla-feel pack because its real-chemistry simulation mods — not fictional tech tiers like Mekanism or Create — are doing the heavy lifting behind isotope refinement and reactor mechanics. Check the Antimatter Chemistry pack page for the full mod list before picking a tier below. 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.
4 GB
This is below Antimatter Chemistry's own recommended floor. It might limp along solo for a short session, but the pack's chemistry-simulation mods are likely to stutter or crash once isotope processing or reactor builds get going — we don't recommend running at this tier.
6 GB
This matches Antimatter Chemistry's own recommended RAM floor and is the right starting point for a small group running Forge 1.12.2 with this pack's chemical processing and isotope mods active.
8 GB
A safer buffer for a mid-size, consistently active group — gives the chemistry-simulation and nuclear physics mods more headroom once several players are running processing chains at the same time.
12 GB
Recommended once you're running 10+ players or a long-lived world with multiple active isotope refinement and reactor setups generating ongoing simulation load.
