Which setup for your Minecraft server?
In a few seconds, estimate the RAM your Minecraft server is likely to need (Vanilla, Paper, Forge, heavy modpack, players, plugins). We rely on our internal benchmarks and feedback from our customers to point you to a suitable plan, without undersizing.

Why HelloServ for Minecraft?
The right amount of RAM isn't enough: you also need a fast processor, a server that stays online, and someone who answers when things go wrong.
Ryzen 9 at 5 GHz and NVMe
Minecraft computes most of each tick on a single core: clock speed matters as much as RAM. Worlds and modpacks are stored on NVMe and load fast on startup.
24 Tbps+ Anti-DDoS included
Every server is protected against DDoS attacks, with no paid option required. Attack traffic is filtered before it reaches your server, so your players stay connected.
Support 7 days a week
Reply within 24 h per ticket, often much faster on Discord. A question about RAM, Paper, Forge or your modpack: a real person from the team gets back to you.
How we calculate RAM
The calculation starts from a RAM grid by server type and player count, adds the weight of plugins, then a 12 % margin. The goal: a figure that holds up on the evening everyone logs in, without making you pay for RAM you don't need.
- A grid per server type
- Vanilla, Paper, Forge and modpack each have their own reference values at 2, 5, 10, 20, 30, 50, 100 and 150 players. Between two tiers, the value is interpolated: the curve follows actual load rather than a flat rate per player.
- The weight of plugins and mods
- Each tier (None, A few, Many, Extreme) adds a few gigabytes, more on Forge and modpack. Mapping and logging plugins like Dynmap or CoreProtect are the most demanding.
- A 12 % margin
- It absorbs short spikes: mass logins, explosions, dimension changes. For a very large modpack or more than 150 players, message us before ordering.
Frequently asked questions about Minecraft RAM
Everything you need to know before picking a plan.
How much RAM for a Vanilla Minecraft server?
For Vanilla with 5-10 friends, we usually recommend about 4 GB in practice. From 20 players, plan for 6 to 8 GB. Beyond 30 players, 10 to 12 GB. Vanilla is more efficient than modpacks but consumes more than older estimates suggested: modern players load 200-500 MB each on average depending on view distance.
How much RAM for a Paper server with plugins?
Paper/Purpur is highly optimised but plugins add up. For 10-20 players with 10 common plugins (EssentialsX, LuckPerms, WorldEdit), 6-8 GB is comfortable. For 30-50 players with 20-30 plugins including heavy ones (Dynmap, CoreProtect, DiscordSRV), aim for 10-12 GB. For 100+ players, 16 GB minimum.
How much does a big modpack like RLCraft or ATM9 consume?
Large modpacks start heavy. Official and community recommendations: RLCraft 6-8 GB for 2-5 players, 12 GB for 10 players. All The Mods 9/10: 8-10 GB minimum, 12-14 GB for 5 players, 16-20 GB for 10-20 players. GregTech and kitchen-sink packs (150+ mods) require 14-16 GB even with few players. Undersizing causes crashes, lag and world corruption.
Does view distance impact RAM?
Yes, and more than you might think. Going from 10 to 16 chunks increases RAM per player by ~50% and CPU by 50-80%. Our Ryzen 9 plans up to 5 GHz comfortably handle 10-12 chunk view distance. For 16+ chunks with many players, pick the next tier. Tip: lowering simulation-distance to 4-6 chunks cuts entity load 2-3x.
Why a margin on top of the grid?
The grid gives a typical load; the extra 12% leaves room for the Java heap during spikes (XP farms, explosions, several players joining at once). Without it, a server can saturate at the first spike even though the average looked fine. For extreme cases, go one tier up or ask our support for advice.
The recommended plan is out of stock, what now?
Our stock system is real time. If the recommended plan is unavailable, you can either pick the tier just above or contact us on Discord/ticket: we can usually free a machine within 24 h or offer a Ryzen VPS with turnkey Minecraft installation.
