# no overclocking               :    700   |    250    |    400     |      0
# mode 'Modest'                 :    800   |    300    |    400     |      0
# mode 'Medium'                 :    900   |    333    |    450     |      2

# mode 'Turbo'                  :   1000   |    500    |    600     |      6
# mode 'Pi2'                    :   1000   |    500    |    500     |      2


# arm_freq=700
# core_freq=250
# sdram_freq=400
# over_voltage=0


# set to 'force_turbo=1' to disable dynamic overclocking (you can lose your warranty!)
  force_turbo=0


# If you have any data corruption using Turbo Mode and overclocking
# try with this setting uncommented
# If this still fails, try to use Medium mode without "over_voltage=2"
# If it ultimately keeps failing, forget about this until it gets fixed
# Use a more conservative mode that will works fine in any cases:
# initial_turbo=30
