The "Minecraft Has Run Out of Memory" error is one of the most commonly occurring in Minecraft. With the game's huge popularity it seems everybody wants to play it, even if their computer isn't up to scratch. Minecraft Bedrock Edition Download
The memory error occurs when the amount of RAM that your computer has (or the amount that is allocated to Minecraft by your computer) is exceeded by the application itself. But don't worry, this is a lot easier to fix than it might seem!
Readers note that the recommended amount of RAM for Minecraft is 4GB, whilst the minimum amount that is specified on the Mojang website is 2GB, so if you're not up to these marks then you may experience some performance issues.
One of the quickest and easiest ways to prevent this error from reoccurring is to simply lower the Video Settings in the pause menu of Minecraft. Some of the settings which are most important are lowering the Render Distance and changing the Graphics from Fancy to Fast.
Another quick fix is to change the priority of Minecraft.exe in your task manager. The task manager can be opened by pressing Ctrl+Shift+Esc on the keyboard. From there you simply need to right click on the Minecraft.exe program and change the "Priority" setting to High. This allocates more of your PC's resources to running Minecraft, which should ultimately improve performance.
Installing 64-bit Java is another way to increase the performance of Minecraft. Java is the application within which Minecraft runs, it is therefore very important that you run the version which is applicable for your operating system. You can easily tell which operating system you are running by going into the Control Panel and then selecting "System" or "System Properties". Not only will this tell you whether your OS is 32-bit or 64-bit, but you can also tell how much RAM you have. If you have a 64-bit OS then you should download the 64-bit version of Java from Adobe's website which will allow Minecraft to run more optimally.
Our final quick and easy fix for the Minecraft Has Run Out of Memory error is to install the Optifine Mod. This is one of the most popular mods that is available for Minecraft, used to improve Minecraft's performance and reduce the load it bears on your PC. Whilst many people think that installing mods is a difficult process, the opposite is true of Optifine, with a dedicated installer being available to do all the hard work for you.
