Frequently asked questions
Download VNISH TOOLKIT, set up your network range and write the firmware directly to NAND. Our step-by-step guide walks you through the whole process.
Open the installation guideVNISH is a professional alternative firmware for ASIC mining devices. It boosts device efficiency and adds advanced monitoring and remote management.
Installing alternative firmware may affect the manufacturer's warranty. However, you can revert to the original firmware at any time.
The boost depends on the device model, cooling and power conditions. Under suitable conditions, S-series devices can gain up to 30%.
The firmware uses a small percentage of the hashrate as a developer fee. It is 2.8% on the S21/S19 series and 2% on the L9/L7 series.
Yes. With the fleet management dashboard you can monitor, group and bulk-update hundreds of devices from a single screen.
A wide range of models is supported, including Antminer S23, S21, S19, S17, the T series and L11, L9, L7, L3. See the devices section for the full list.
