How to fix “crc check error” on Bitmain Antminer L3+ ASICs

Welcome to this trooubleshooting guide on how to fix CRC Check errors on Bitmain Antminer L3+ ASICs. CRC Check errors are a common issue that can occur on these devices, and they can be caused by a hardware or software issue. If you’re experiencing this error, it’s important to take the necessary steps to troubleshoot and fix the issue, as it can impact the performance and profitability of your mining operation. In this guide, we’ll provide you with a step-by-step troubleshooting process to help you diagnose and fix the CRC Check error on your Bitmain Antminer L3+ ASIC. Whether you’re a seasoned miner or a beginner, this guide will provide you with the information you need to get your device up and running again.

Troubleshooting Steps to fix “crc check error” on Bitmain Antminer L3+ ASICs

  1. Identify the type of issue: Determine whether the CRC Check error is caused by a hardware or software issue. Look for error messages like “check_register_value: crc check error!!! crc5 value = 0x1f, return crc = 0x09” or “check nonce: return nonce crc error. crc = 0x12” in the kernel logs.
  2. Check hardware connections: Make sure all cables and connections are properly connected and secure. Inspect all components, connections, and cables to ensure they’re in good condition and working properly. Check the power supply unit (PSU) and cabling for any signs of wear or breakage.
  3. Restart the device: Try restarting the device by unplugging it from the power source and plugging it back in after a few minutes.
  4. Update firmware: If you suspect a software issue, try updating the firmware on your device. Connect your Antminer to a computer using SSH protocol and install the latest version of firmware files on your miner’s ASIC board and controller board respectively.
  5. Reset to factory settings: If none of the above steps work, try resetting your device to its factory settings.
  6. Check domain voltage: If the above steps didn’t work, check whether the domain voltage is normal. If it’s normal, check whether the voltage of the RI signal is normal. If the voltage of the RI signal is abnormal, check the domain voltage of the domain where the chip is located and the LDO chip’s 1.8V input and 0.8V output. If the voltage of the LDO chip is abnormal, replace the LDO chip. If the voltage of the LDO chip is normal, there may be a problem with the ASIC chip in this domain. Therefore, check whether the signal voltage of the chip is abnormal. If it’s abnormal, re-solder it first. If the problem cannot be solved, replace the ASIC chip.
  7. Contact customer support: If none of the above steps work, contact customer support for further assistance or consider sending your Antminer in for repairs or replacement if the device is still under warranty.
