If your game is crashing with Out of memory errors, or, you’re playing modded Minecraft and need to allocate more RAM, this guide will show you how.

If you’re expecting more intense gameplay, or have a world with a lot of redstone machines, or mob farms, you should consider a minimum of 4GB or even 6GB.
