How Much RAM Does an Official Tensura: Reincarnated Survival Server Need?
Official Tensura: Reincarnated Survival Server is the official NeoForge 1.21.1 modpack built directly by ManasMods, the creators of the Tensura mod — its skill, race, and evolution systems add real memory overhead beyond vanilla Minecraft. Check the Official Tensura: Reincarnated Survival Server pack page for the full mod list, then use the tiers below to pick a starting allocation. 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.
5 GB
Bare minimum for solo play or testing the pack alone. You can boot and explore Tensura's skill and race systems, but there's little headroom once more systems load in, and a second player will likely push you into memory pressure.
8 GB
The recommended starting point for Official Tensura: Reincarnated Survival Server. This matches the catalog's own recommended floor for the pack and gives Tensura's skill, race, and evolution systems enough headroom for a small group of 2-4 players without constant garbage-collection stutter.
10 GB
A safer allocation for a mid-size, consistently active group of roughly 5-8 players, especially once multiple players are actively using skills and exploring further from spawn.
12 GB
Recommended for 10+ players or a world that's been running long-term. Long-lived worlds accumulate more loaded chunks and more player skill/race data in memory, and the extra headroom keeps that from turning into lag.
