How Much RAM Should I Allocate to Minecraft?

Minecraft is a popular game that people of all ages love to play this game. It requires more RAM to give a better gaming experience. So, if you are thinking, how much RAM should I allocate to Minecraft? Then you are in the right place.

How Much RAM Should I Allocate to Minecraft To Run It Smoothly?

It depends on factors you must consider before allocating the RAM for Minecraft. The factors are:

1. Number of players: The server needs more RAM to run smoothly if many players are in the game. But the server needs less RAM if fewer players are in the game.

2. World size: The larger the world, the more RAM your server will require.

3. Plugins/ mods: If you’re playing Minecraft without using any mods, you can allocate 1.5 GB of memory to the game, which exceeds the standard 1 GB requirement.

But if you are installing different types of mods or texture packs, it will burden your computer. In this case, you must share 4 to 5GB of Minecraft. At the same time, keep other programs closed on your PC. Avoid using mod packs with numerous mods on a computer with just 8 GB of RAM; otherwise, you will face many issues while playing the game.

Avoid unnecessary RAM allocation to Minecraft so the Java garbage collector can quickly clean the space. Conversely, if you allocate small RAM to Minecraft, the Java garbage collector will get frequent calls to clean the space. That can cause disturbance for you, especially when you are in the middle of the game.

Available Plans for Minecraft Dervers:

Amount of RAM	World Size	Perfect for
1GB	Upto 4GB	It is a perfect plan for playing vanilla Minecraft with a small group of people but without mods or texture packs.
2GB	Upto 8GB	It’s a fantastic plan for adding some mods and players.
3GB	Upto 10GB	It is the perfect plan for servers with a medium number of players, mod packs or plugin packs. It can bear 25 mods or plugins.
4GB	Upto 15GB	It is a fantastic plan. It can afford 35 to 40 mods or plugins.
5-12GB	20-120GB	It is the perfect plan for a large number of players. It can support more than 40 mods or plugins.
16GB	150+ GB	It is a robust plan for large communities and supports many mods or plugins.
