Installation Manual

  • Download BiXBiT firmware for M2x series
    Use WhatsMinerTool for the installation

    It is necessary to flash the ASIC using the SD-card if the firmware cannot be installed using WhatsMinerTool. For this:
  • Check the version of your control board (for M2x these are H3, H6, H6oscontrol boards)
  • Download the utility for reverting your equipment to the service firmware: H3, H6 or H6os
  • Prepare the ASIC for SD card flashing. The detailed process is shown in the video below:
  • Once the firmware is installed, open the ASIC’s web panel and go to the Configuration>Miner Configuration>Overclock. The configuration settings of your ASIC are located here.

    This section also has the Immersion Cooling option, which has to be checked if you immerse the ASIC into liquid. If there are errors related to the PSU cooler, it is required to flash the PSU using the function in the firmware: Miner configuration > PSU firmware > Upgrade PSU firmware
