VNISH Functionality

Free custom firmware for mining with virus protection and AsicBoost technology.

Complete Virus Protection

Protection and built-in treatment against various viruses. (ANTBUILD, NIGHT SWITCHER and others).

Hotel Fee

The function of redirecting part of the capacity to pay for electricity, equipment placement or payment for miner services.

Auto Tuning

Automatic adjustment of frequencies, voltage of ASIC chips (reduction of HW errors, increase of hashrate, extension of ASIC lifespan)

Bulk Firmware Installation

Possibility of installing firmware on an unlimited number of miners in one network at the same time.

Automatic Switching

The function of automatic profile lowering when the temperature rises and profile raising when the temperature returns to normal.

Individual Overclocking

Overclocking each board separately (frequency and voltage). Overclocking each chip (thanks to this, you can achieve maximum speed of the ASIC and stable operation).

Saving Electricity

The function of automatic profile lowering when the temperature rises and profile raising when the temperature returns to normal.

Extending Fan Life and Turning Them off

The fan operation algorithm has been redesigned: quiet start, maintaining the temperature on the chips for their stable and long-term operation. Possibility to disable fan polling during immersion cooling (no tricks needed).

FAQ

We have detailed instructions for each version of the miner. Everything is described simply and clearly, so even a beginner can handle it. In addition, you are always supported by our team of technical specialists who are always available and ready to help.
Yes, with one button from the miner's web interface or using the HASHCORE TOOLKIT
Absolutely not. All firmware is thoroughly tested before release.
Our software is distributed free of charge. Please note that the custom firmware includes a developer fee (DevFee) – a reward for developers. DevFee depends on the type of equipment, is 1,8% – 2,8% of the total hashrate of your miner, which is automatically written off during the operation of the device.
