Is using a custom ASIC firmware from BiXBiT free?

Our software for Antminer, Whatsminer is distributed for free. Please keep in mind that custom firmware includes Developers Fee, which is a reward for developers. Usually it is 1.8%-2.8% of the miner’s total hashrate which is automatically deducted during the work of the device.

Why the ASIC does not start after selecting a profile?

If you mean the very first run after flashing the device, it sometimes takes up to an hour for the inbuilt algorithm to finish configuring your ASIC.

How to bypass the “Cannot Find Signature” message during the flashing process of the ASIC?

Read our user manual for your specific miner version, it describes actions to eliminate this error, when it occurs.

Does the ASIC lose its warranty from the manufacturer when used with a custom firmware?

There is no definite answer. To avoid warranty issues, please use the firmware from the manufacturer.

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

Absolutely not. All firmware revisions are thoroughly tested before each release. Moreover, all BiXBiT capacities have been running on these firmwares for many years.

Is BiXBiT AMS compatible with microprograms from other developers?

No. Our automated monitoring system is only compatible with our software.

Is it possible to revert the ASIC back to its original settings after using a custom firmware?

Yes, just bring back the official firmware in the usual way.

What level of knowledge is required to flash a miner?

We have specially made instructions for every version of the miner. Everything is described in a simple and clear way, so even a beginner can handle it. Besides, you are always backed with our team of technicians who are always in touch and willing to help.

6.1 Options Available on the Overclock Tab

In this tab, functionality is provided to overclock/undervolt the device using generated profiles, as well as by manually setting overclocking parameters. The tab also contains options for enabling immersion cooling mode and connecting an additional power supply unit.

[Liquid Cooling]:

This checkbox is intended to switch the device to immersion cooling mode.
When activated, the device’s fans are no longer monitored by software.
It is typically used in conjunction with [Disable Power Fan].

Notes:

When this mode is enabled, in Miner Status → Summary, the Fan Speed parameter changes to Liquid Cooling.
If this mode is enabled while fans remain installed, they will continue spinning, but the device will not be able to control their rotation speed.
This function can also be used when cooling the device with non‑standard fans.
PREPARING THE MINER FOR THE DIVE

[Additional PSU]:

This mode is intended for connecting an additional power supply unit to the device.

[Startup Cooling Fan Speed]:

This parameter is intended to configure the fan rotation speed (in percentage) from the end of the initial purge (fan speed – 100%) until the device begins operation. It defines the speed at which the device starts cooling.

Note: This parameter does not disable the initial purge cycle — the fans will always run at full speed during startup, which means the device will produce noise at launch regardless of this setting.

[Fan Mode]:

This function is intended to switch the operating mode of the fans.
It has two states:

[Auto] – the fan rotation speed is determined automatically.
[Manual] – the maximum fan rotation speed is limited by the [Manual Fan Speed] parameter.

[Manual Fan Speed]:

If manual cooling mode is enabled, this parameter serves as a limiter for the maximum fan power of the device.

If the device begins to overheat while operating in this mode, it will ignore manual fan control and switch to automatic fan management.

[Current profile]:

Profiles are generated on the device over a certain period of time, typically up to one hour.
On older device models, profiles may be pre‑installed by default (In such cases, the Generate Profiles button is not available).

Profiles marked as Predicted are calculated mathematically and have not been tested by the device in practice. For profiles with this designation, the final performance indicators may differ from the stated values

[Lower profile if Autotune failed]:

When this option is enabled, if the device fails to tune on the selected profile, it will automatically downgrade to a lower profile and initiate the tuning process on that profile.

[Advanced options]:

Manual overclocking options for advanced users.
In most cases, it is recommended to use the generated overclocking profiles

The values displayed in the fields of this section depend on the selected generated profile and are automatically updated when the profile is changed. If you manually modify these values, they will take priority over the parameters of the previously selected profile.

Therefore, to avoid accidental application of manually entered data during device overclocking, it is recommended to reselect the required overclocking profile and disable the [Advanced options] checkbox.

Target Frequency: The desired average frequency of the chips on the boards, which the miner will aim for during auto‑tuning.
Target Voltage: The desired voltage supplied to the boards, which the miner will aim for during auto‑tuning.
Minimum Voltage: The minimum voltage that the miner will apply to the boards during auto‑tuning.
Maximum Voltage: The maximum voltage that the miner will apply to the boards during auto‑tuning.
Target Board Temp: Not recommended to change. The board temperature that the miner targets during auto‑tuning and operation. If it is not possible to maintain the specified temperature, the miner will allow deviation up to the maximum possible (85°C), after which it will reduce the chip frequency and, accordingly, the hashrate.
Chip Ok Percent: Not recommended to change.
PSU Power Limit: The power consumption in watts that the miner will aim for. Actual consumption may exceed this value during operation, but not beyond PSU Power Max. The recommended value is 100–200 W lower than PSU Power Max, but not more than 3800–3900 W.
PSU Power Max: The maximum allowable power consumption. If this value is exceeded, the miner will generate an error. The recommended value should not exceed the rated capacity of the miner’s power supply unit, typically 3900–4000 W.
PSU Power Rate: Not recommended to change.

In the columns on the right, you can see a hint for the selected profile in the form of:

Default – the default value
Min – the minimum possible value in the field
Max – the maximum possible value in the field

During overclocking, it is necessary to monitor the chip temperature (not to be confused with the board temperature, which is displayed in the web interface under the ChipTemp column).

This temperature can also be viewed in the ChipTemp column of the WhatsMinerTool utility.

In the utility settings, the parameter List Column Display Mode must first be set to Complete Mode; otherwise, the ChipTemp column will not be displayed.

Decoding the value string “116.0_72.1_93.8”:

116.0 – maximum chip temperature
72.1 – minimum chip temperature
93.8 – average chip temperature of the miner

The permissible operating temperature limit for chips, as defined by the manufacturer, varies across different miner models. When this limit is exceeded, the miner reduces the chip frequency.
Although such temperatures are considered acceptable, it is not recommended to operate the miner under these conditions in order to avoid potential malfunctions.

Error: Restart As Hashrate Error – occurs on devices of the M2X series.
It can be resolved by entering into Minimum Voltage the value indicated in parentheses of the corresponding error in System.log (expect vol: …).
In such cases, it is also required to increase Target Voltage and Maximum Voltage by +50 and +100 relative to Minimum Voltage, respectively.
[Generate Profiles/Stop profiles generation/Regenerate Profiles]:

[Generate Profiles/Stop profiles generation/Regenerate Profiles]:

This button has three states:

[Generate Profiles] – displayed by default. When pressed, the profile generation process begins. The list of profiles and the active profile can be viewed in the [Current profile] field.
[Regenerate Profiles] – displayed if the profile generation process has completed successfully. When pressed, the profile generation process starts again.
[Stop profiles generation] – displayed if the profile generation process has not yet completed. When pressed, the profile generation process is stopped

[Delete Autotune Results]:

Deletes the results of auto‑tuning. This button may be absent if the device has never completed a tuning process.
