How Much RAM Does a Whispers From Below Server Need?
Whispers From Below is a Forge 1.20.1 cave-horror pack built around From the Caves, whose ancient creature is dangerous only underground — safe on the surface, relentless the moment players go caving. That underground-only threat, plus the pack's layered performance and atmosphere mods, is what actually drives its RAM needs; see the full breakdown on the Whispers From Below pack page.

2 GB
Bare minimum for solo play or a tiny two-person group. Forge plus From the Caves' creature tracking will run, but cave generation and the pack's performance mods leave almost no headroom — expect stutter the moment chunks load fast.
4 GB
The best starting point for most Whispers From Below servers. This matches the pack's own recommended RAM floor and gives Forge, From the Caves, and the atmosphere mods enough room to run the caving loop without constant garbage-collection pauses.
6 GB
Safer for a mid-size active group exploring multiple cave systems at once. The extra headroom matters because From the Caves' creature tracking and the pack's visual atmosphere mods both scale with how much underground terrain is loaded simultaneously.
8 GB
Recommended for 10+ players or a long-running world with a large explored cave network. At this point chunk retention from sprawling underground bases is the bigger cost than the mod list itself, and the extra RAM keeps things smooth.
