// Benefits Firmware

Take control of your mining

Firmware is a key tool in any ASIC miner's arsenal, serving as the core required software

Increase mining efficiency

Optimize your device performance with profiles. The profile switcher automatically adjusts profiles based on temperature, and in case of an ASIC error, it switches to lower settings to ensure stability. Overclocking with an additional power supply is supported, as well as downvolting down to -50%.

Feedback on bone work from our partner

On average our switching losses lowered from 10 minutes to 4 which is a 60% reduction in lost revenue.

It's been great to work with the BiXBiT team and iterate on this valuable firmware. The firmware enables us to efficiently use Whatsminers in curtailment events, which are frequent if you're maximizing gross profit in West Texas

FAQ

Is it free to use BiXBiT's custom ASIC firmware?

Our custom firmware for Whatsminer and Antminer includes a developer fee, which is automatically deducted during device operation to keep the firmware up to date.

  • for the M2x series — 2%
  • for all other firmware — 2.8%.

How to install the firmware correctly?

You can read the step-by-step instructions or watch the video tutorial on YouTube.

Where can I get a complete list of profiles?

To get a list of profiles, use the Auto Profile Generation feature in the Overclock tab. This takes about 40 minutes, and the results depend on the environment and the condition of the ASIC.

Why does the ASIC have a low hash rate after selecting a profile?

After selecting a profile, the ASIC undergoes an “Autotuning” process, which takes up to 1 hour, depending on the environmental conditions and the state of the ASIC. After completing the “Autotuning” process, the ASIC will enter the selected operating mode.

Does ASIC lose its manufacturer's warranty when using custom firmware?

The warranty is not void due to the firmware. To transfer the warranty, you need to reflash the ASIC to the factory firmware using an SD card.

Is it possible to restore the device to factory firmware?

Yes, there are two ways to do it:

  • via SD card — completely removes traces of custom firmware;
  • using WhatsminerTool — the firmware will be rolled back, but traces of the custom firwmare will remain.

Why can't I install the firmware via SD card?

There may be several reasons:

  • the SD card is faulty;
  • the SD card capacity is too high (we recommend using cards up to 8 GB);
  • the installation files have been recorded incorrectly;
  • there are problems with the SD card slot on the device.

What should I do if the firmware won't download or the website is temporarily down?

Try the following:

If the problem persists, contact technical support, which is available 24/7

Is it risky to use custom firmware from BiXBiT on the ASIC?

Absolutely not. All firmware versions are thoroughly tested before each release. Moreover, all partners devices have been operating on BiXBiT firmware for many years.
