  • Download the custom firmware. (dont unpack it)
  • Flash by going to "System" -> "Upgrade" -> "Flash new firmware image" and select the custom firmware.
  • After flashing, check the advanced settings page and start at the lowest voltage setting and 400mhz. From there increase your frequency to see how high you can go at the lowest voltage setting.
  • Start tweaking some more. See the profile suggestions below.
