How Much RAM Does a Better MC [FABRIC] BMC1 Server Need?
Better MC [FABRIC] BMC1 — see the full Better MC [FABRIC] BMC1 pack page for details — runs on Fabric for Minecraft 1.19.2 and adds biome mods, structure mods, and performance mods like Sodium and Iris on top of vanilla. This is the original BMC1 build, not the newer Better MC [FORGE] BMC4 flagship on 1.20.1 Forge, and its RAM needs differ from a plain vanilla server because of that extra mod stack.

2 GB
The bare minimum for a solo or 2-player world. Chunk loading and biome generation mods will feel sluggish, and you'll have little headroom if you add more mods later. Only use this for quick testing.
4 GB
The recommended starting point for Better MC [FABRIC] BMC1. This matches the pack's own baseline for the full biome, structure, and performance mod stack on Fabric 1.19.2, and covers small groups of 2-5 players comfortably.
6 GB
A safer choice once you have 5-8 players actively exploring. The extra headroom covers simultaneous chunk generation across multiple new biomes without the server stalling on garbage collection.
8 GB
For 10+ players or a world that's been running for weeks and has generated a lot of new biome and structure terrain. Long-lived BMC1 worlds accumulate more loaded chunk data than vanilla, so extra RAM keeps TPS stable.
