How Much RAM Does an FTB Direwolf20 1.12 Server Need?
FTB Presents Direwolf20 1.12 is the classic 1.12.2 kitchen-sink pack from the FTB Presents Direwolf20 1.12 pack page, stacking Thermal Expansion, Applied Energistics 2, Ender IO, and Mekanism — so sizing RAM correctly up front matters more than on a lighter pack. Here's how the tiers break down. 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 for solo play or testing the install. Tight once Thermal Expansion and Ender IO machines start running — fine for checking the pack boots, not for a real session.
6 GB
The best starting point for most FTB Presents Direwolf20 1.12 servers. This matches the pack's own recommended floor and covers Thermal Expansion, AE2, Ender IO, and Mekanism running together for a small group.
8 GB
Safer for a mid-size active group building out AE2 networks and Mekanism processing lines in parallel — gives headroom as the base expands and more chunks stay loaded.
12 GB
For 10+ players or a long-running world with multiple active tech bases. At this scale the pack's combined mod load and world size benefit from the extra buffer.
