How to fix “hashboard voltage is inconsistent” on Bitmain Antminer S17+ ASICs

If you’re a Bitmain Antminer S17+ ASIC miner user and encountering voltage inconsistency issues on the hashboard, don’t panic. Inconsistent voltage can cause hashing errors, reduce efficiency, and potentially damage your hardware. But with the right approach, you can fix this problem and get your miner running smoothly again. In this guide, we’ll provide you with some general troubleshooting steps that can help you identify the issue and fix it. It’s important to note that these are general guidelines, and your specific miner may have different troubleshooting procedures or requirements. So, if you’re not confident in performing the repairs or modifications yourself, it’s always recommended to consult the user manual or seek professional assistance.

Troubleshooting Steps to fix “Chain only find 0 ASIC” on Bitmain Antminer S17+ ASICs

1. Evaluate if the voltages of your hashboards are consistent. Check the kernel logs for a message such as “Voltage are different. Will exit.”
2. Gently remove and re-seat all of your hash boards to ensure they are properly connected.
3. Outdated firmware could prevent your hash boards from maintaining a consistent voltage reading. You can update the firmware by going to Miner Software > System Management > Upgrade/Downgrade Firmware.
4. If you still encounter the “hashboard voltage is inconsistent” issue, it may be due to EEPROM corruption, or you have mixed hashboards from different machines. In this case, you can try rewriting the suggested voltage values inside the PIC using different tools, such as the ARC Tester or a PICKit, to normalize the EEPROM values on all three hashboards.
5. First, you should check the voltage of the hashboard using an oscilloscope during operation. The voltage should be between 1.45-1.65V. If the voltage is inconsistent, move on to the next step.
6. Measure the voltage of the hashboard using a multimeter. The voltage should be around 0.7-0.9V. If the voltage is inconsistent, try reflowing the solder joints on the hashboard.
7. Check the power connectors to ensure that all connectors are properly connected and not loose. Loose power connectors can cause voltage inconsistencies.
8. Make sure that your miner is properly cooled. High temperatures can cause voltage inconsistencies, so check the cooling system of your miner.
9. If none of the above solutions work, consider sending your miner for repair to a professional ASIC repair center or service provider.
