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
