Minecraft Calculator FAQ
How does the Minecraft RAM Calculator work?
The Minecraft RAM calculator is based on long research and case studies. The RAM per player, mod, or plugin is an estimate for best outcome of what resources you need.
While these numbers may not be absolute, they are the average of how much RAM a server needs to operate properly.
Alternatively, you can use our other server management tools.
Why is my Minecraft server crashing?
Minecraft servers often crash due to low amounts of RAM used by your OS. If you are using Windows to host your Minecraft server, reserve at least 4GB of RAM for your system.
As Windows is resource extensive, you should not allocate all of your RAM to your server. If you wish to allocate more RAM to your server, use a different OS such as Linux. It requires only 512MB of RAM to keep your system running smoothly.
Does Minecraft server need CPU?
Minecraft servers require a CPU to be installed in order to operate. Single-threaded CPU from the Intel Celeron brand could handle plenty of player traffic, as it is designed for such purposes. And since Minecraft doesn't use multi-threaded CPU's, you can easily invest in almost any budget CPU, rather than buying a gaming one.
Can my computer run a Minecraft server?
Any computer can run a Minecraft server, even the older ones. Our Minecraft server RAM calculator gives you estimates of how many players it can upkeep with plugins or mods installed.
Why is my Minecraft server laggy?
Many Minecraft servers have lag issues. While the basic cause may be lag machines or too many actions.
Is 1 GB of RAM good for a Minecraft server?
If you are playing older versions of Minecraft like 1.12 and below, 1GB of RAM is good for a server. However, versions 1.13 and above require at least 4GB to power up and use your server.
Is 4GB RAM enough for a modded Minecraft server?
Modded Minecraft servers require more RAM than those using plugins. Using 4GB of RAM to run mods could keep your server playable, but it depends on how much RAM is allocated, and what mods you wish to play. The recommended starting RAM is between 4 to 6GB to keep your server in good health.
