FEATURES
Sleep mode
This function allows you to stop and resume mining within 15 seconds, with the possibility of completely stopping the fans. This will allow you to get maximum profitability if the cost of electricity is different during the day.
Monitoring
Take advantage of our APIs, easily compatible with your own in-house monitoring system.
Up to 30% hashrate boost
Unlock the true potential of your ASIC miners with optimized performance
Tuning & Optimization
VNISH enables miners instantly change the hashrate to get maximum of profitability, during the period of the hash price decrease, the miner's hashrate will be reduced. Similarly, when Hashprice rise, miners can capitalize on this trend by foregoing efficiency and overclocking, enhancing overall fleet profitability.
Mass installation and cloning module
Ability to install firmware and transfer the config (settings, pools, workers) to unlimited number of miners in one network at the same time
Temperature Management
auto switch presets function enables miners to regulate the temperature of their mining hardware effectively. By choosing optimal operating preset, Vnish helps reduce overheating preventing equipment failures, operating safely in high-temperature environments and increasing the longevity of your miners.

Increase in profitability up to 20-25% due to reduced consumption compared to stock firmware
Installing the firmware is possible without SD card directly to NAND of the miner using the VNISH HASHCORE TOOLKIT (Download, unzip, install, read tutorial)
You can read tutorial clicking this link
You can do it easily using our utility vnish online updater (VOU)
At the moment, the Vnish Hotel fee function is cut from the functionality of the Vnish firmware, but we can build an analogue for you – a personal version of the Vnish firmware with the inclusion of your pool, worker and percentage.
To fix the DevFee offline error, you need to update the firmware to the latest version.
Download VOU (Updater software) and update your miners to the latest version automatically:
For Windows: https://vnish.us/files/tools/vou_win.zip
For Android: https://vnish.us/files/tools/vou_android.apk
For macOS: https://vnish.us/files/tools/vou_mac.zip

IF YOU STILL HAVE A PROBLEM AFTER THE UPDATE:
Install Google DNS on your miner.
To install and change the miner’s DNS, In the left menu:
System -> Network -> Disable DHCP.
DNS 1 : 8.8.8.8
DNS 2 : 8.8.4.4
Save and reboot
Yes, a return is possible, there is a rollback function in the firmware
Dev Fee (developer fee) - percentage of the miners hashrate which is redirected to developers pool.
21, 19 series - 2.8% , L9, L7 series - 2%

When using vnish firmware, the service life is not reduced, the service life is affected by farm conditions (temperature, power stability, timely maintenance). The warranty is not canceled, since the firmware does not leave any traces when returning to the stock
You can view the operating modes at the following links : X21 series, X19 series, L9/L7 series
We offer additional discounts for large miners, contact us and we will reach the best terms.
1. What Is It?
The auto-profile switching feature automatically adjusts your mining equipment’s settings based on current cooling conditions. This ensures optimal performance and stability while reducing the need for manual intervention.
2. How It Works
The system monitors the equipment’s temperature and automatically switches between hash rate profiles to prevent overheating. You can define a range that sets both the minimum and maximum limits, beyond which the device will not operate.
3. Key Benefits
Enhanced performance
Lower power consumption
Increased equipment lifespan
By maintaining consistent operating temperatures, this function helps prevent overheating and reduces component wear.
4. Setup Instructions
Step 1: Enable the Feature
Open the equipment settings menu
Navigate to the Performance tab
Activate the Auto-profile switching option
Step 2: Select Your Profiles
Configure the default (starting) profile. This will also serve as the fallback in case of rising temperatures. In critical situations, performance may drop below this level.
Step 3: Set the Upper Limit
Choose the maximum profile level that the system should not exceed. This prevents overloading and maintains stable operation.

6. Recommendations
Regular Monitoring: Periodically review and adjust profile settings to match current operating conditions and performance goals.
Effective Cooling: Ensure your cooling systems are functioning properly to prevent thermal stress on the hardware.
The auto-profile switching function streamlines the operation of mining equipment, promoting stability and efficiency. By tailoring settings for each model and setting an upper profile limit, you gain better control over performance while protecting your hardware.
