Frmware is stable, well-optimized, and we've seen a boost in hashrate... Issues resolved fast and professionally.
Big thanks to Sasha et al. You guys rock. Fantastic support + have saved us a great deal. See you in Hong Kong.
Moved over from stock firmware back in fall. Our fleet performance has improved massively across all key metrics. Power efficiency, stability, and overall control are on a completely different level. The support team feels like an extension of our own engineers. Special thanks to Vlad and Evgeniy for bearing with us through the tests!
Long-time client (took some convincing to get us to move from a competitor back in 2022) – currently running Vnish on our S19 XP / S21 fleet in Finland – does what it says on the tin. Haven't found better fees, efficiency or support with any other provider.
What impressed us most about Vnish is their technical understanding of our hardware. Every recommendation we get is practical and grounded in data. With their firmware, we achieved better efficiency without compromising stability. Wouldn't go back.
Performance, reliability, and fast support. A very strong, reliable partner. Make sure to go direct for best dev fees
Thank you Bradley. Our experience with Vnish has been extremely positive. Technical issues are handled quickly, updates are well-tested, and the efficiency gains are consistent.

FAQ
The ASIC mining firmware contains low-level instructions that govern the interaction of the miner's hardware components. Additionally, the firmware handles the miner's communication with pools through various data exchange protocols and monitors the mining process in specialized programs using built-in API functions. Provides advanced security options and virus protection.
ASIC mining firmware is tailored to the specific hardware configuration of the ASIC miner and the cryptocurrency algorithm it is designed to mine. It includes instructions for managing various aspects of the hardware, such as regulating voltage, controlling clock speeds, managing thermal conditions, and coordinating communication with mining pools and blockchain networks.
By using the Vnish ASIC mining firmware, miners can optimize the performance of their hardware and improve the efficiency of their mining operations. This can result in higher mining profits and a more stable mining experience.
Vnish ASIC mining firmware is highly customizable. Miners can adjust a wide range of settings, such as clock speed, voltage, and fan speed, to optimize performance and efficiency. New generation of firmware contain presets for various combinations of the mining process.
All available actual Vnish firmware can be downloaded from the official website of the developers or the websites of their partners. The official website is vnish.com.
The installation process for ASIC mining firmware varies depending on the specific firmware being used. Generally, it involves downloading the firmware file, flashing it onto the hardware, and configuring the firmware settings. More detailed information can be found on the installation guide page.
It is generally recommended to update ASIC mining firmware every few months to ensure optimal performance and security. It is important to review the release notes and potential risks before updating and to back up critical data before performing a firmware update.
The Vnish firmware installation process is designed to be safe. If something goes wrong during the update, it should not result in hardware damage or data loss. If an issue does occur, it may be necessary to contact Vnish customer support or seek assistance from the Vnish firmware community.
In general, it is not recommended to downgrade ASIC mining firmware as it may introduce compatibility issues. If downgrading is necessary, carefully review the instructions and back up any critical data before proceeding.
Most third-party mining firmware requires complex rollback procedures. Vnish firmware allows rollback to the stock firmware version in one click directly from the miner menu.
After installing Vnish firmware, the security level of the ASIC miner is increased. Additional features include SSH protocol control and advanced virus protection. These improvements significantly reduce potential security risks compared to stock firmware.
You can verify the integrity of the firmware image by checking its MD5 checksum and ensuring it matches the checksum provided on the website.
Yes, you can become a Vnish partner and join the referral program. More information is available via the official partner link.
a) What does the name of the firmware file mean?
The firmware file name contains information about the brand or partner, miner model, control board type, installation method, firmware version, and file type (install or update). This helps users select the correct firmware for their equipment.
b) How to choose the Vnish firmware suitable for my mining equipment?
Check your miner model and control board type on the device label. Then visit vnish.com and select the appropriate firmware from the supported model list, which currently includes 23 Antminer x19 series modifications.
c) What is DevFee and how does it work?
DevFee is a developer commission of 2–2.8% of hashrate redirected to the developers' pool. The exact value may vary in real time but remains within the limits specified in the agreement.
d) What is Autotune and how it works?
Autotune automatically adjusts voltage and frequency for each individual chip. Higher quality chips receive higher frequencies, while lower quality chips receive lower frequencies to achieve optimal performance.
e) How can I get maximum hashrate with Vnish firmware?
Maximum hashrate can be achieved by manually adjusting voltage and frequency or using tested performance profiles. Profiles are available for air and liquid cooling setups, as well as different power supply configurations.
f) How can I reduce power consumption with the Vnish firmware?
Power consumption can be reduced using manual control mode or preset profiles designed for optimal or reduced power usage. Reference tables for hashrate and power consumption are available for each miner model.
g) How long time takes Autotune process, is any indication when it finish?
The Autotune process typically takes 3–4 hours and does not require additional reboots. Progress is shown in the status bar and browser favicon. Once completed, the profile is marked as tuned.
