How Much RAM Does an FTB Revelation Server Need?
FTB Revelation packs IndustrialCraft, Thermal Expansion, Botania, Applied Energistics, and Tinkers' Construct into one Forge 1.12.2 kitchen-sink, so RAM sizing matters even though it's lighter than expert-mode packs on the same version. Check the full details on the FTB Revelation pack page before you pick a plan. 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
Bare minimum. Workable for a solo player or a tiny two-person group, but it's cutting it close for a pack that loads IndustrialCraft, Thermal Expansion, Botania, AE2, and Tinkers' Construct all at once — expect tight headroom once builds grow.
6 GB
The best starting point for most FTB Revelation servers. This matches the pack's own recommended allocation and comfortably covers its full mod list for a small-to-medium group without constant garbage-collection pressure.
8 GB
Safer for a mid-size, active group. Gives real breathing room once players start running AE2 autocrafting setups, Thermal Expansion machine lines, and Botania mana flux side by side across multiple chunks.
12 GB
For 10+ players or a world that's been running for months. At this scale the kitchen-sink mod list plus a large explored map benefits from the extra heap to avoid tick lag during peak activity.
