Allocating Memory
Most modpacks require you to set the amount of allocated memory (RAM) for Java to use. Here's how you set it.
The method to allocate memory depends on the program that you are using to run the modpack. Instructions for the most popular launchers can be found below.
The amount of memory that should be allocated for Enigmatica modpacks is shown in the table below, but optimal amounts may vary depending on the total memory available in your system

Never allocate more memory than your PC can spare. The below table shows maximum values depending on how much RAM your PC has.
