Recommended RAM
3 GB
That's the Iron plan — $10/mo.
Start with 4 GB

Heuristic: 2 GB base for vanilla + ~154 MB per concurrent player, rounded up. Every plan upgrades in one click with the world preserved, so starting small is safe.

Built for performance

Everything your world needs to run smooth.

Hardware and tooling tuned specifically for Minecraft — not a generic VPS with a wiki page bolted on.

Your resources. No one else's lag.

Every server runs in its own isolated container with the RAM and CPU of your plan reserved up front — a busy neighbor can never eat your ticks.

How the recommendation works

Server memory is driven by two things: what's installed (every mod loads its content permanently, which is why heavy packs idle at 5+ GB before anyone joins) and how many chunks are loaded (each player keeps their own radius of world in memory). The calculator uses a base allocation per workload plus a per-player margin — the same sizing table as our full RAM guide, which also covers the symptoms of getting it wrong.

Wondering about the price side? The cost calculator runs the same sizing and leads with the monthly number.

Questions, answered.

How much RAM does a Minecraft server need?+

2 GB runs vanilla for 2–4 players; 4 GB is the friend-group sweet spot; plugin servers want 4–6 GB; modded servers 6–8 GB; kitchen-sink modpacks 8–12 GB. The calculator above sizes it from your exact player count and workload.

Does more RAM fix Minecraft server lag?+

Only when RAM is actually the bottleneck (garbage-collection freezes, OutOfMemoryError crashes). Steady low TPS is usually single-core CPU speed or world generation — more memory won't change it, and oversized allocations can stutter more.

How much RAM per player?+

Roughly 150–300 MB per concurrent player on top of the workload's base, driven by how spread out players are — each one keeps their own radius of chunks loaded.

What if I pick too little?+

On Campfire, upgrading a plan is one click and your world comes along — so start with the recommendation and scale when the server tells you to.
