So the last thing you want is error messages killing your fun. So here’s a guide on how to allocate more RAM in Minecraft! Since the rather primitive days back in 2009 when Mojang would release Minecraft to the masses, the franchise has gone from strength to strength.

With a multitude of updates improving the quality of this title being gifted to players, the modding community growing in skill to add more depth and nuance to the already very open-ended sandbox environment, and ports being available for any modern platform that you choose, Minecraft is everywhere and rightfully so.

So with this push towards a higher quality of life and the inclusion of mods within Minecraft, players sometimes come across a few related issues. One of the most common issues Minecraft Modders will come across is that insufficient memory is being allocated to the game. It sounds like a problem that only technically savvy people will be able to deal with but in fact, it’s really simple to fix.

Why does this happen?

The cause of this problem is often down to the increasing number of mods that you install for Minecraft. With each addition to your vanilla game, you will be asking more of your system when you boot up the game.

A vanilla version of the game will rarely ask for more than 2GB of memory allocation from your system, whereas a modded version of Minecraft will range from anything from 4GB to 6GB depending on the version you are running.
