Antminer S19 / S19 Pro / T19 Overclocking Board – 18-30% Hashrate Improvement
This overclocking board replaces the stock Antminer control board on S19, S19 Pro and T19 miners with a KINTEX-7 FPGA-based controller and proprietary overclocking firmware that increases hash rate by 18–30% through hardware-level voltage and frequency tuning. Unlike firmware-only overclocking, this approach provides tighter chip-level control and better stability. The kit includes the overclocking motherboard, 7× 18-pin IO data cables, 4× fan simulators and 1× 4-pin voltage regulation line.
Hardware vs Firmware Overclocking
Firmware-only overclocking pushes the stock control board beyond its designed operating parameters, which limits how far frequency and voltage can be safely raised. This dedicated overclocking board uses a KINTEX-7 FPGA as the main controller, giving it direct hardware control over each hashboard's voltage and frequency domains — enabling higher, more stable overclocks with less risk of chip damage. The board mounts in the miner's top housing and connects to the hashboards through the included 18-pin cables.
Requirements & Installation
Good heat dissipation is essential — oil cooling, liquid cooling or a low-ambient-temperature environment is recommended for sustained overclocked operation. The control board must meet AMCB07_4X1_4F_S specifications. Install the overclocking board in the top housing, connect the 7 data cables to the hashboards, plug in the fan simulators and voltage regulation line. Verify firmware compatibility before powering on. Not all firmware versions have been extensively tested.
