Block rewards shrink, power prices climb, and replacing your fleet means new capital outlay and new risk. The cheapest extra output is raising the performance of the hardware you already own.
HOW TO INSTALL FIRMWARE: Match the full model variant and control board, then compare the downloaded file's SHA-256 with the published value
Installation guidePer-chip auto-tuning unlocks the performance your hardware already has.
Efficiency profiles cut watts per terahash and extend hardware life.
Auto-switching presets protect your miners through heat waves and winters.
Install and clone settings across unlimited miners in one network.
Automate, monitor and integrate with your own stack via complete APIs.
Track every metric live and fine-tune profit as conditions change.

Create a folder, for example C:\VNISH on Windows, and put the downloaded .tar.gz inside it without unpacking or renaming it. Select the folder, not the archive. An empty-looking folder picker is normal: it shows folders, not files
Open the miner's web interface, check the installed version and your pools. Watch temperatures, hashrate and errors until stable before expanding to other miners
Same device, 16% less power for 4% less hashrate: energy per terahash drops from 15.0 to 13.1 joules. At $0.095/kWh that lifts daily margin by more than 15%.
Hashrate, thermal bands, pools, fans and per-board health. This is the interface behind every build on this page.
Fewer watts at almost the same hashrate: the power bill drops faster than output - that is where the extra margin comes from

ROI ASIC is the official distribution of VNISH firmware - the most widely used custom ASIC firmware on the planet. One product, done properly: real builds, real support, real economics
For mining hotels, colocation providers and large fleets: your logo, your personal fee, our full technical support. Every hosted ASIC becomes your recurring revenue stream.
A complete 2026 presentation: product, economics, security and partnership terms. Ten languages, ready to forward to your team or partners.
Yes. The build is free to download and run. While the firmware is actually running, a small share of hashrate supports its continued development - always visible in the dashboard, never hidden. On a well-matched ASIC the extra income normally outweighs this small share several times over. When you return to stock, the fee stops automatically - no penalties, no exit fees. That share funds what keeps the product alive: new releases for new models, round-the-clock technical support and the ecosystem the team has been building since 2017.
SD/USB recovery is a separate board-specific procedure. On AML with stock from September 2025 or later, USB unlocking may be needed for that recovery route, not as a blanket prerequisite for Toolkit installation Third-party firmware can affect the manufacturer's warranty. Do not bypass security warnings, interrupt writing or use a file for a similar model
47 models across the S21, T21, S19, L7 and L9 series, including Hydro and Immersion versions, on Amlogic, BeagleBone, Xilinx and CVITEK control boards.
Installation time depends on the hardware, current firmware and selected route. Start with one miner and wait for the operation to finish
Free download. Every build reversible to stock.
