Firmware

Description

Vnish firmware is a powerful alternative software solution for BTC and LTC ASIC miners, created to replace the manufacturer’s stock firmware ( Bitmain Antminer). Vnish functions as a full-fledged “operating system”, intelligently managing hardware components, operating modes, and seamless communication with mining pools.

How Vnish differs from stock firmware

The firmware delivers advanced, low-level control over mining hardware, removing the limitations of stock software in overclocking, downvolting, and large-scale fleet management. This makes Vnish a mission-critical tool for professional mining farms and mining hotels.

Key Value Proposition

Unlocking the full potential of ASIC hardware by increasing hashrate, stability, and energy efficiency to maximize long-term profitability.

Overview of key features

FeatureDescription
Performance
OverclockingIncreasing chip clock frequencies to achieve higher hashrate beyond factory limits.
DownvoltingLowering clock frequencies and supply voltage to reduce power consumption and improve overall efficiency.
AutotuningIntelligent automatic optimization of frequency and voltage for each individual chip to deliver maximum performance and stability within the selected profile.
Presets AutoswitchDynamic switching between profiles to select the most optimal overclocking mode based on current operating conditions.
Power
Keep power when lost pool connectivityAutomatic power retention or shutdown when connectivity with the mining pool is lost.
Pause miningTemporarily stops mining and reduces fan speed to minimize energy consumption.
Power widgetDisplays estimated or actual power consumption values, depending on the power supply model.
Control and Diagnostic
Mass firmware install / UpdateProfessional tools for simultaneous firmware installation or updates across large numbers of devices.
Mass ConfigurationRapid deployment of settings (pools, passwords, presets) across selected groups of miners.
Chip / Heat MapClear visual representation of individual chip status and performance on hash boards.
Find MinerIndicator blinking for quick physical identification of a specific device.
Diagnostic reportsGeneration of detailed diagnostic reports to analyze potential issues and hardware downtime.
