Bigger miner support, smarter thermal protection, advanced power management, and massive stability improvements for next-generation ASIC mining.
Built for Modern ASIC Mining
VNISH Firmware 1.3.3 is one of the biggest updates yet — bringing expanded support for the newest Antminer generations, smarter safety systems, advanced power controls, and major stability improvements designed for professional mining farms and home operators alike.
This release focuses heavily on reliability, thermal protection, tuning precision, and operational flexibility, giving miners more control over efficiency, uptime, and power consumption than ever before.
What’s New in Version 1.3.3
Expanded Miner Support
Support added for major new Antminer models including S21 Pro, S21 XP, S21+ Hydro, S19 XP+ Hydro, and additional hashboard revisions.
Advanced Power Control
New throttle controls allow miners to instantly scale hashrate and reduce power consumption without fully stopping mining operations.
Smarter Thermal Protection
Automatic PSU temperature monitoring and adaptive preset management help prevent overheating while improving long-term hardware reliability.
Improved Autotuning
Enhanced tuning algorithms deliver better stability, more accurate voltage management, and improved efficiency across supported models.
Offline Mining Mode
Miners can now continue operating without internet connectivity, ideal for temporary outages or isolated mining environments.
