Diagnostic Entry Point: All operational faults are recorded in the Kernel Log. Review these steps to isolate and resolve primary hardware failures.
1. Error: 'Chain [X] only find 0 chips'
- Reseat data ribbon cable connecting control board to hashboard.
- Inspect 12V-15V DC busbar screws for oxidation or loose contact.
- Test 1.8V and 0.8V LDO voltage regulator outputs on hashboard input domain.
2. Error: 'Fan speed too low' / '0 RPM'
- Inspect fans for physical obstructions or bearing failure.
- For immersion/hydro conversions: install 4-pin Fan Spoofers or disable fan monitoring in custom firmware.
3. Error: 'High Temperature' / 'Temp Read Failed'
- Blow out dust felt between aluminum heatsinks using 6-8 bar compressed air.
- Replace degraded thermal paste (minimum 6 W/mK thermal conductivity).
- Inspect LM75 I2C temperature sensors on boards reporting 0°C or missing telemetry.
4. Error: 'Cannot connect to Stratum pool'
- Set DNS servers manually to
8.8.8.8and1.1.1.1. - Switch port to 443 / SSL if ISP blocks standard stratum port 3333.
- Configure fallback Failover pools to maintain continuous uptime.
