Pangolin Whatsminer is really a power consuming device with a hash rate of 12.5Th/s. To overclock Pangolin Whatsminer M3X we need a modified image. Since there is no option to set frequency manually rather it uses the auto frequency which uses an algorithm to set the best hash rate for the device.
In my opinion, Whatsminer gets very heated and overclocking can destroy this device. Therefore, we should not try any manual configurations to the hardware components of this device. Pangolin measures the humidity and temperature of the atmosphere and then compares it with Miner. Finally, it gives the best frequency to operate and stabilize the device which provides more life to the device.
