TL;DR:
- 4 GB is enough for a small vanilla group of friends.
- 8 GB fits a server with plugins or a light set of mods.
- 8 to 12 GB is where big modpacks like ATM10 start. Busy modded worlds need more.
How much RAM does a Minecraft server need? Start with 4 GB for a few friends on vanilla, 8 GB for plugins or light mods, and 8 to 12 GB for a big modpack. Then watch your server's TPS and add more only if it struggles. Our free Minecraft RAM calculator works it out for your player count, plugins, and view distance.

RAM by server type
Find the row that matches your server. Group size means people online at the same time.
| Server type | Group size | Start with |
|---|---|---|
| Vanilla | a few friends | 4 GB |
| Paper with plugins | small to medium | 8 GB |
| Fabric, Forge or NeoForge with a few mods | small to medium | 8 GB |
| Big modpack (ATM10, Better MC) | small group | 8 GB |
| Big modpack, busy world | larger group | 12 GB or more |
More players, a long view distance, and lots of exploring all push memory up. A world where everyone stays near spawn needs less than one where each player flies off in a different direction.
Here's what each size costs on berrybyte today:
| RAM | Price |
|---|---|
| 4 GB | $9.95/mo |
| 6 GB | $14.95/mo |
| 8 GB | $19.95/mo |
| 10 GB | $24.95/mo |
| 12 GB | $29.95/mo |
| 16 GB | $39.95/mo |
Bigger plans go up to 32 GB. Prices are in USD. Check the plan selector on the Minecraft hosting page for the current price before you buy.
How much RAM for a modded Minecraft server?
Modded servers need more memory than vanilla. Every mod loads its own blocks, items, and code. Most big packs start at 8 GB.
Here's where some popular packs start on berrybyte:
| Modpack | Starting RAM |
|---|---|
| Cobblemon | 4 GB |
| COBBLEVERSE | 6 GB |
| RLCraft | 6 GB |
| ATM10 | 8 GB |
| Better MC | 8 GB |
| DeceasedCraft | 10 GB |
Some of these numbers come from the pack creator. Others are our own starting estimates. The modpack comparison shows which is which.
Running a different pack? Look it up in the modpack RAM requirements tool. It searches Modrinth, CurseForge, and FTB. You can also browse all modpacks and install one in one click.
Signs your server needs more RAM
Lag can come from a lot of places, so check before you buy more memory. The best signal is TPS (ticks per second).
- TPS below 20. The spark guide to TPS and MSPT says a healthy server runs at 20 TPS. That means each tick takes 50 ms or less.
- Out of memory crashes. The console shows an
OutOfMemoryErrorbefore the server stops. - Chunks load slowly when players explore new areas, even when few people are online.
One thing that is not a sign: the dashboard showing RAM near 100%. berrybyte applies Aikar's flags to Paper, Spigot, and Fabric-family servers. They make Java claim the full allocation at startup. To see real use, install spark (a plugin on Paper, a mod on Fabric or Forge) and run /spark health. The Aikar's flags guide walks you through it.
RAM isn't everything
More RAM won't fix every kind of lag. Past a certain point, extra memory does nothing for a small server. Paper's Aikar's flags guide puts it plainly: "more memory does not mean better performance above a certain point."
Three things often help more than extra memory:
- Run Paper instead of the vanilla jar. Paper adds a lot of performance fixes and runs most Spigot plugins.
- Pre-generate your world. New terrain is one of the heaviest jobs a server does. Chunky builds it ahead of time, so players load finished chunks.
- Lower the view distance. Each step up loads more chunks around every player. Our server.properties generator helps you set it.
The CPU matters too. A Minecraft server does most of its work on one main thread, so fast cores beat lots of slow ones. berrybyte runs Minecraft on AMD Ryzen processors with NVMe storage.
Upgrading later
You don't have to guess right on day one. Start with the size that fits your group today. On berrybyte, the server owner opens the server's Overview page and presses Upgrade on the Plan card. You pay only the difference, then restart the server to use the new memory.
Modded groups that grow fast should plan one size up. If a modpack world outgrows 8 GB, 12 GB is the usual next step.
FAQ
Is 4 GB of RAM enough for a Minecraft server?
Yes, for a small vanilla group of friends. It gets tight with lots of plugins, a long view distance, or mods. For those, start at 8 GB.
Is 8 GB of RAM enough for a Minecraft server?
For most Paper servers with plugins and for many modpacks, yes. ATM10 and Better MC start at 8 GB. A busier modded world usually does better on 12 GB.
Is 1 GB of RAM enough for a Minecraft server?
Not for a modern Minecraft world with friends. Recent versions need more memory than old ones did. For a server people play on, start at 4 GB.
Is 10 GB of RAM too much?
Not for a big modpack. DeceasedCraft starts at 10 GB. For a small vanilla group, it's more than you need, and the money is better spent elsewhere.
Does a modded Minecraft server need more RAM?
Yes. Every mod adds blocks, items, and code. Most big packs start at 8 GB, and a busier modded world does better on 12 GB. Check your pack in the modpack RAM requirements tool.
How much RAM per player does Minecraft need?
There's no fixed number per player. What players do matters more than how many there are. Ten players building near spawn can use less than five players exploring new land. Use the RAM calculator for a starting point.
How do I check how much RAM my server is using?
Install spark and run /spark health. It shows real memory use. On Paper and Fabric servers, the dashboard's RAM bar shows the full amount Java has claimed, so it often reads near 100%.
