What is mining firmware?
Mining firmware is the software that runs an ASIC miner. Aftermarket firmware replaces the manufacturer's to give the operator more control.
How it works
It can tune each chip, run the machine below its rated power for better efficiency or above it for more hashrate, and change targets automatically. Using it may affect the manufacturer's warranty.
Why it matters
Running a fleet at lower power is often the cheapest way to stay profitable when hashprice is low.
