Cryptocurrency mining is a complex process involving various electronic components, including power supplies, processors, and cooling systems. When any of these components fail or malfunction, it can cause significant disruptions to mining operations, reducing profitability and causing frustration for miners. One common issue that can affect mining operations is unstable power supply voltage. In this troubleshooting guide, we will outline the steps you can take to identify and resolve power supply voltage instability issues on Bitmain Antminer S17 ASICs. These steps help you diagnose the issue and implement solutions to get your miner back up and running smoothly. Following these steps, you can address power supply voltage instability issues and keep your mining operations running at peak efficiency.
Troubleshooting Steps to fix “power supply voltage is unstable” on Bitmain Antminer S17 ASICs
- The first step in troubleshooting the issue is to check the miner’s kernel logs for any “ERROR_POWER_LOST” messages or “more than 1.0v diff” alerts. These logs can provide essential clues as to what might be causing the voltage instability.
- Check the power supply unit (PSU) to ensure it functions properly and provides enough power to the miner. You can use a multimeter to measure the power output of the PSU. Make sure the PSU is compatible with the miner and properly configured.
- Ensure the power outlets function correctly and provide stable power to the power supply. Unstable power sources can cause voltage fluctuations that can affect the stability of the miner.
- Measure with a Multimeter Whether the Antminer Power Supply 6pin Line has 12V Output
- Turn off and unplug the miner from the power source
- Locate PSU and 6pin connectors for hash boards (labeled J1, J2, J3)
- Set the multimeter to DC and voltage measurement
- Connect the black test lead to the ground wire pin, and the red test lead to the positive wire pin on the same connector
- Check the multimeter display for around 12V output
- Repeat for all pins on all connectors for each hash board
- Check that the power cables are correctly connected and that there are no loose or damaged cables. Ensure that the wires are properly secured to prevent any accidental disconnections.
- Check Whether Your Miner is Properly Grounded
- Miners should avoid touching any metal shelves
- Set Fluke 17b+ multimeter to A/C 220V
- While miner is running, place test lead of multimeter on exposed aluminum body/case and metal frame of mining machine
- If multimeter displays no voltage or less than 1V, miner is well grounded
- If multimeter displays high voltage (more than 10V), miner is not grounded properly
- It is important to fix grounding issue as soon as possible.
- High temperatures can cause the power supply voltage to become unstable. Monitor the miner’s temperature to ensure it is within the recommended range. Check that the cooling fans are working properly and that the air vents are not blocked.
- Ensure that the mining software is functioning correctly and not causing any issues with the power supply voltage. Check for any updates or patches that might address any known issues.
- If you have ruled out the other possible causes, the miner may have a hardware issue. In this case, you may need to replace a faulty component or contact the manufacturer for support.
- If you have tried all the above steps and are still experiencing voltage instability issues with your Antminer S17, it may be time to seek professional help. Contact a qualified ASIC repair technician, such as those at D-Central, to assist you in resolving the issue.
