One of the most common questions new server admins ask is: "How many GB of RAM do I need for my Minecraft server?" Under-buying memory leads to server crashes, out-of-memory errors, and severe TPS drops. However, over-allocating RAM can actually hurt your server's performance due to long Java Garbage Collection (GC) pauses.
In this guide, we break down recommended RAM allocations by server software type, active player count, and modpack complexity.
RAM Requirement Breakdown Table
| Use Case / Server Type | Plugin & Mod Estimate | Player Capacity | Recommended RAM | Recommended Plan |
|---|---|---|---|---|
| Vanilla / Paper (Small SMP) | 0 - 3 Basic Plugins | 1 - 4 Players | 2 GB - 3 GB | Dirt / Grass Plan ($1.02 - $1.80/mo) |
| Paper / Purpur (Standard SMP) | 10 - 25 Essential Plugins (AuthMe, LuckPerms, EssentialsX) | 5 - 12 Players | 4 GB - 6 GB | Grass / Stone Plan ($2.37 - $3.61/mo) |
| Heavy Spigot / Paper + Geyser | 25 - 50+ Plugins (Economy, Towny, GeyserMC Cross-Play) | 10 - 20 Players | 6 GB - 8 GB | Stone / Iron Plan ($3.61 - $4.75/mo) |
| Light Modpacks (Create / Cobblemon) | 50 - 100 Mods | 4 - 8 Players | 8 GB - 12 GB | Iron / Diamond Plan ($4.75 - $7.03/mo) |
| Heavy Modpacks (ATM 10 / RLCraft / DawnCraft) | 150 - 300+ Mods | 4 - 8 Players | 12 GB - 16 GB | Diamond / Netherite Plan ($7.03 - $9.30/mo) |
| Large Network / Mega SMP + Geyser | 50+ Plugins + Bedrock Cross-Play & BungeeCord | 20 - 40+ Players | 16 GB - 32 GB | Netherite / Elytra Plan ($9.30 - $16.55/mo) |
Why Modded Servers Require Significantly More Memory
Unlike Paper or Spigot servers which optimize Vanilla code, Forge and Neoforge modpacks load hundreds of custom block registries, entity models, item states, and sound effects directly into RAM during startup. Running out of heap space causes instant server freezes during world loads.
