Change Minimum or Maximum RAM
Allocating RAM is easy! Just move the sliders to your desired value. You can set the value to the nearest half a gigabyte.



Technical Notes
  • Most modpacks B-Gaming run require 6GB of RAM to run smoothly.
  • We recommend setting the miminum and maximum to the same value.
    • Having the JVM expand and contract the heap while chasing the 'free to used ratio' that it targets can be expensive and generate and cause random lag spikes.
  • Avoid allocating more than 1/2 your total RAM unless you know what you're doing.
  • The slider will change color based on how much RAM you allocate.
    • Green: Less than 1/4 of your total available RAM.
    • Yellow: Greater than 1/4 of your total available RAM.
    • Red: Greater than 1/2 of your total available RAM.
  • The minimum amount you can allocate is determined by the following.
    • Total RAM < 6GB : 2G
    • Total RAM ≥ 6GB : 3G
  • The maximum amount you can allocate is determined by the following.
    • Total RAM ≤ 16GB : (Total RAM) - (1GB for OS) - (1GB per each 4GB of RAM)
    • Total RAM > 16GB : (Total RAM) - (1GB for OS) - (1GB for each 8GB of RAM > 16GB) - (1GB per each 4GB of RAM)
Change the Java Executable
  • Click Choose File.
  • Navigate to the JRE/JDK you wish to use.
  • Select the executable.
    • Windows: bin\javaw.exe
    • macOS/Linux: bin/java

Modify JVM Arguments
Advanced use only. Do not specify -Xmx or -Xms here. These values are modified by the memory sliders.
