Supported Antminer models
Release 1.6.0 adds universal compatibility for all Antminer models — regardless of factory firmware version. That includes the latest and legacy units across multiple series:
- Antminer S21 / T21
- Antminer S19 / T19 and the broader 19 series
- Antminer 21 and other new model families
- Antminer L7 and the L7 series
Because the method removes firmware-date restrictions, operators can now upgrade and manage fleets of mixed-generation devices from one central Toolkit instance. For the self-guided installer and model-specific notes, visit this self-installation page.
Benefits & performance highlights
Key advantages of remote installation with Vnish/Hashcore via Hashcore Toolkit:
- Eliminates travel to the farm and SD-card based workflows.
- Automates bulk deployments across large IP ranges.
- Reduces installation errors with built-in validation and logging.
- Supports rollbacks and monitoring during the operation.
Performance & optimization claims
Many operators report measurable gains after switching to the official Vnish firmware. Typical improvements include an increase in Antminer profitability by up to 25% and reduced power consumption by as much as 15%, depending on model and tuning.
Engineers have also developed specialized builds — for example, a firmware for Antminers S21/T21 with overclocking to 300,000 Hz and dedicated firmware for Antminers S19 with overclocking to 200,000 Hz — enabling higher hashrates where hardware allows safe operation.
Operators running Antminer L7 series units can also benefit from optimized tuning in the Vnish builds for improved stability and efficiency.
Added short promotional phrases with embedded links:
- official Vnish firmware delivers optimized heat and power profiles for 24/7 mining.
- Many farms have upgraded Antminer 21 and noticed faster deployment cycles using the Toolkit.
- Legacy Antminer 19 models are fully supported for remote installation and tuning.
- The L7 series get tailored power- and frequency profiles to maximize long-term uptime.
- Documented results include an increase Antminer profitability by 25% in optimized setups.
- Through careful power management and firmware optimizations, miners can achieve a reduce Antminer power consumption by 15% on selected rigs.
- Specialized firmware for Antminers S21/T21 with overclocking up to 300,000 Hz supports higher sustained throughput when paired with proper cooling.
- Tested builds include a firmware for Antminers S19 with overclocking up to 200,000 Hz profile for S19-class devices.
How to get started — quick guide
- Download the Hashcore Toolkit from the official page: Hashcore Toolkit.
- Prepare the NAND installation files for your specific model (do not unpack archives).
- Create an IP range group in the Toolkit and scan your network.
- Select miners, choose
Install Firmware, and follow the on-screen prompts. - Monitor installation progress and validate uptime after the reboot.

FAQ
Q: Do I need physical access or SD cards?
A: No — Release 1.6.0 supports fully remote NAND-based installs through Toolkit.
Q: Is every Antminer model supported?
A: Yes — the update enables installation on all Antminer models regardless of factory firmware date.
Q: Where can I learn about overclock profiles and safety?
A: Overclocking profiles (for example S21/T21 to 300k Hz or S19 to 200k Hz) are model-specific and documented on the official self-installation and firmware pages. Proceed only with adequate cooling and monitoring.
