How Much RAM Does a Sculk Horde Survival Server Need?
Sculk Horde Survival (see the Sculk Horde Survival pack page) is a Forge 1.20.1 pack where scheduled waves of sculk-infected mobs attack your base between rounds of resource-gathering and defense-building — a tower-defense-adjacent loop that puts different, bursty load on your server compared to a normal survival pack. Here's how much RAM to budget for it. 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, solo or a tiny 2-player group. It can run, but expect noticeable lag right when a sculk horde wave spawns and the mob count spikes.
6 GB
The best starting point for most Sculk Horde Survival servers. This matches the pack's own recommended RAM floor and gives enough headroom to absorb a wave spawn without the server stuttering.
8 GB
Safer for a mid-size active group — several players building and defending bases at once, with more entities and structures alive between waves.
12 GB
For 10+ players or a long-running world where multiple bases, farms, and accumulated defense structures from past waves are all loaded at once.
