How much RAM should I allocate to Minecraft?

How much RAM should I allocate to Minecraft depends on several factors, such as the size of the game world, the number of players, and the number of mods or plugins installed. As a general guideline and according to the experts, the minimum recommended amount of RAM for Minecraft is 2GB. But, if you plan to run a large server with many players and/or mods, you must allocate more RAM to the game.

A helpful rule of thumb for allocating RAM for Minecraft is to dedicate 0.1GB to 0.2GB of RAM per player and an extra 1-2GB for the server itself. For example, if you plan to run a server with 10 players and no mods, you should allocate at least 2GB to 4GB of RAM (1-2GB for the players and 2GB for the server). The following table will better tell you how much RAM should I allocate to Minecraft.

Note: The ‘≃’ stands to showcase ‘up to’ in the table below. Moreover, the values included in this table are our recommendations, so you may have different RAM sizes for different mods, players, and world sizes if you want.

When allocating more RAM to Minecraft, it’s important to remember the following:

1. The RAM allocation method only works for Minecraft: Java Edition, not Minecraft: Bedrock Edition.

2. You need to know how much RAM is installed on your computer before allocating it to Minecraft.

3. It’s recommended to allocate less than two-thirds of your PC’s total RAM to Minecraft to dodge potential issues and slow down your computer performance.
