Since its release in 2009, Minecraft has been hanging among the most played games. While other games decrease in popularity after a while, Minecraft has been on the opposite trend i.e., increasing in popularity. Due to its popularity, Minecraft is played on a plethora of different hardware devices and configurations.

The main challenge faced in running the game smoothly by hardware devices is the allocation of RAM for Minecraft. For a smooth, lag-free gaming experience, some tweaks are required. We will properly guide you on how to allocate more RAM to Minecraft, so let us look at some methods.

Available RAM of the System

Before you tinker with the settings, it is important to know the amount of slotted RAM in your Pc and how much of that is available for use. To do this, simply follow the steps below:

  1. Navigate to the windows toolbar, and right next to the Windows logo, there should be a search option.
  2. Search for system information.
  3. After opening the former, you will be greeted with information. Scroll down, and you will find ram information about your machine.

Reason for the Allocation of More RAM

Allocating more RAM increases the performance of the game. It allows for some resources to be used for the game, giving a good headway for performance. This negates the fps drops that some people may encounter. Also, for the folks who like running mods on this game allocating more ram for this purpose can be beneficial.

Amount of RAM that should be Allocated

There is no right or wrong here. Allocating the amount of ram is dependent on your system’s configuration. If you have a high-end PC with a good amount of available memory, it is wise to allocate half of the memory for the game. The sweet spot for RAM allocation is around 4GB.
