How Much RAM Does a Vault Hunters Server Need?
Vault Hunters is one of those packs where being slightly too low on RAM feels fine right until it does not. The right answer depends on whether this is a small co-op run or a long-lived group world with regular vault activity.
8 GB
Small co-op serverCan work for a lighter group, but not the safest long-term choice.
10 GB
Most normal groupsBest starting point for most Vault Hunters multiplayer servers.
12 GB
Busier progression serverSafer when more players are active and the world stays busy.
16 GB
Long-running community serverBest for larger groups, heavier automation and longer worlds.
Simple recommendation
Start at 10 GB if you want the least surprising path for a normal multiplayer Vault Hunters server. If you want a quicker estimate for your exact group size, use the Minecraft modpack RAM calculator.
FAQ
Is 8 GB enough for Vault Hunters?+
It can work for a smaller co-op world, but 10 GB is the better starting point for most groups because the pack becomes heavier as the world and progression grow.
Why does Vault Hunters need more RAM than lighter modpacks?+
Because it combines a heavy mod stack, progression systems and longer active sessions. The server keeps more of the world busy and exposes low-memory plans faster.
Should I start at 12 GB immediately?+
Only if you already know the server will stay busy. For many groups, 10 GB is the better balance and you can scale up if the world proves it needs more.
