The Antminer T9+ firmware by BiXBiT allows to maximize the performance of mining era veteran devices and reach 15Th/s. The BM1387 chips are compatible with AsicBoost technology, which ensures optimal power consumption in operation.
The AsicBoost algorithm reduces power consumption by ~200W per device. The combination of this technology with automatic tuning of each device significantly improves the performance and energy efficiency of the entire farm. This firmware also eliminates the flaw that reduced the operating efficiency of all chips due to one that is problematic. The developer's fee is 1.8%.
