Vnish official firmware | BITMAIN

Up to 20% Hashrate Increase

Vnish delivers up to a 20% hashrate boost thanks to its intelligent auto-tuning system. The firmware interacts with each individual element of the hash board, analyzes chip characteristics, and selects optimal voltage and frequency settings. This personalized approach increases performance without compromising stability.

Ready-made overclocking profiles are also available and can be selected depending on current needs. When maximum computing power is required, simply activate the appropriate mode — and the miner will switch to a high-performance hashrate mode. This is especially beneficial during periods of rising BTC prices, when every additional terahash directly impacts profitability.

Chip Auto-Tuning

Even within a single hash board, chips may differ in performance characteristics: some operate stably at higher frequencies, while others perform best at medium levels. Stock firmware applies identical parameters to all chips, reducing overall efficiency.

Vnish analyzes each chip individually and assigns optimal parameters. This allows you to:

• Increase total hashrate;
• Reduce power consumption;
• Prevent overheating of individual modules.

The auto-tuning system runs in the background and continuously adjusts parameters to maintain maximum performance.

Security System

The firmware includes multi-level protection mechanisms that ensure stable miner operation under various conditions. If temperatures exceed safe limits, the device automatically shuts down, preventing overheating and potential damage to chips or power supply units.

Protection against incorrect voltage is also implemented: if values exceed safe thresholds, the system blocks operation and notifies the user of the issue. This allows safe testing of overclocking profiles — all critical scenarios are monitored and controlled by the firmware.

Temperature Management

Overheating is one of the primary causes of ASIC hardware failure. High temperatures accelerate chip degradation and negatively affect power boards and cooling fans.

Vnish provides flexible cooling control: you can adjust fan speeds and set temperature thresholds. This helps achieve an optimal balance between cooling efficiency, noise level, and energy consumption.

In colder regions, fans can be set to minimum speed to reduce electricity usage, while in hot climates the system automatically increases cooling intensity. As a result, equipment operates more reliably and has a longer lifespan.

Energy Optimization After Installing Vnish Firmware

A key efficiency metric in mining is the ratio of power consumption to performance (W/TH). Even a slight reduction in this value can lead to significant savings at scale.

Vnish enables voltage regulation, load balancing, and optimization of W/TH performance. In regions with high electricity tariffs, this becomes especially important.

For example, if a standard mode delivers 30 W/TH and an optimized mode delivers 25 W/TH, the annual cost difference can reach tens of thousands of dollars even for a single mining farm.

Error Reduction After Installing Vnish Firmware

ASIC devices are complex systems where every component affects operational stability. Failures may occur due to voltage spikes, overheating, improper cable connections, or contamination within the cooling system.

The firmware enables early problem detection. If one of the chips begins to operate unstably, the system automatically lowers its frequency, preventing the entire board from shutting down.

The built-in logging system provides full access to information about events and errors, allowing users to quickly determine whether technical intervention is required or if a software adjustment is sufficient. This significantly reduces the risk of damage to expensive components.
