How Much RAM Does a Biohazard: Project Genesis Server Need?
Biohazard: Project Genesis is the ultimate apocalypse pack on Forge 1.20.1 — see the Biohazard: Project Genesis pack page for the full mod breakdown. Its broken-world exploration, horde combat, scavenging, base-building, and fully recipe-verified crafting set make it noticeably heavier than a typical zombie-themed pack like DeceasedCraft or Best Zombie Apocalypse - Ultra Realistic, which changes how much RAM it actually needs.

6 GB
Bare minimum for solo play or testing the pack alone. Horde combat, the broken-world generation, and recipe-verified crafting are all running, but there's no headroom — expect slower chunk loading and occasional stutter even with one player.
10 GB
The best starting point for most servers. This matches the pack's own recommended RAM floor and gives horde combat, scavenging, base-building, and the verified recipe set enough headroom to run smoothly for a small group.
14 GB
Safer for a mid-size active group exploring and fortifying multiple bases across the broken world at once. More simultaneous hordes and scavenging zones stay smooth instead of competing for the same tight memory budget.
20 GB
For 10+ players or a long-running world. As the map fills with fortified bases, loot has been picked through larger areas, and the infected population spreads, the extra memory keeps tick rate stable over weeks of play.
