Overview
This page controls the mode presets available on the device. This mode determines the fan speed, and starting voltage/frequency for the autotune process. The device will then adjust based on temperature to reach the highest hashrate possible given the temperature and fan speed provided.
Quiet Mode
Limits Fan Speed to 25%
Tunes to 60C Asic Temperature
Balanced Mode
Limits Fan Speed to 35%
Tunes to 60C Asic Temperature
Default mode after first setup, or after overheat mode has been activated.
Turbo Mode
Limits Fan Speed to 95%
Tunes to 60C Asic Temperature
Limits Power to 25 Watts
Limits Voltage and Frequency to safe operating levels
Auto Tune Overview
Autotune Works in these steps:
Pre-heat: For the first 15 minutes after power-on, no changes are made to allow the device to reach stable temperature.
Raise preset to target Temperature: Once pre-heat ends, the loop increases core clock and supply voltage in small steps until either (a) the die temperature hits the 60 °C set-point, or (b) any hard limit for frequency, voltage, or power is encountered.
Low hashrate → increase voltage only: If temperature is within the ±2 °C band but observed hashrate is still < 80 % of its computed target, the algorithm raises voltage (≈ +10 mV) while leaving frequency unchanged to recover performance.
Over Temp: Whenever die temperature exceeds 62 °C, voltage and frequency is stepped down.
