Points To Remember Before Allocating RAM

First, you might want to understand the RAM recommendations for a Minecraft game.

  • If you have a 32-bit game installed, you can do fine with just 1024 MB (1 GB) RAM.
  • If you have a 64-bit game installed, the minimum requirement is 2GB (2048 MB). For decent gameplay, double it (4 GB or 4096 MB).
  • For the best gaming experience, you can dedicate up to 6 GB of RAM.

To allocate these memory capacities, you need to have sufficient RAM. If you don’t have 2 GB RAM but try to provide the 2GB to the system, it won’t work. It might even overload. You could run into various issues.

As a general rule of thumb, it is better to dedicate a maximum of 50% of your PC’s whole RAM. What does it mean?

  • If you have 4 GB RAM, dedicate up to 2GB to Minecraft.
  • If you have 12 GB RAM, dedicate up to 6 GB to Minecraft.

This rule of thumb works great for almost any kind of game. It won’t hinder your gameplay experience.

Remember that RAM isn’t everything. You will need the best processor and internet connection to play without any problem.

  • Select the Edit option from the list of options in the Menu. In there, you will find a ‘More options’ command. It should be at the bottom-right corner of the window.
  • Once you access it, you will find something reading as ‘JVM Arguments.’ Forget about the entire code. You might see something like ‘-Xmx2G, or -Xmx4G’ on the list. The number dictates the GB of RAM you have allocated. You can change it to 1, 3, 4, 6, or whatever you have available.

  • Make sure that there’s no mistake in the conversion. Otherwise, you can run into errors.
  • Now go ahead and save the text document. Click on File in the Menu bar and select ‘Save all.’ Select the Save As Type to ‘All Files.’ Then use the name: file server launcher.bat
