How To Allocate More RAM To Minecraft

As a seasoned Minecraft player on PC, I can’t stress enough the importance of having sufficient RAM to run this game smoothly, especially when you’re dealing with numerous mods and shaders. The default 2GB RAM allocation just doesn’t cut it for me anymore.


Using Minecraft on a PC gives you the advantage of utilizing various modifications, shaders, and exclusive features for your game. Initially, Minecraft limits the application to only 2 GB of RAM. If you plan on downloading numerous add-ons, insufficient RAM may affect your performance significantly. To enhance overall performance, you can increase the allocated RAM directly within the Minecraft application itself.

Luckily, Minecraft limits your RAM usage automatically, but you can easily override this setting. Here’s how:

  • Click on either “Minecraft: Java Edition” or “Minecraft for Windows” from the left-hand side of the screen
  • On both of these pages, you’ll see an “Installations” tab at the top of the screen
  • Select the Installations tab and hover over your installation of the game
  • By hovering, you can see a three-dot icon appear next to the “Play” button
  • Click the three-dot icon and then press “Edit”
  • Select “More Options” from the bottom of the menu and then find the box labeled “JVM Arguments”
  • By default, this box reads: “-Xmx2G -XX:+UnlockExperimentalVMOptions -XX:+UseG1GC -XX:G1NewSizePercent=20 -XX:G1ReservePercent=20 -XX:MaxGCPauseMillis=50 -XX:G1HeapRegionSize=32M”
  • You can disregard everything in this box except for the start of it, the part that reads “-Xmx2G”
  • This is your current RAM allocation. To change it, simply replace the “2” with 4, 6, 8, 16, or any other possible RAM configuration
  • Click “Save” at the bottom of the screen, and you’re done

How To Allocate More RAM To Minecraft

As a passionate Minecraft player, I suggest considering 4 or 8GB of RAM allocation for your computer. Exceeding this limit could potentially result in problems for your PC. In particular, overloading Minecraft with too much RAM may lead to input lag and delays, even on high-performance systems. However, if you’re using an extensive collection of shaders or mods, it might be necessary to opt for a 16GB RAM allocation to ensure optimal gameplay performance.
