How to Fix Antminer S17 ASICs “Chain Lacks Chips”

Troubleshooting guide: Fix “Chain lacks chips” on Bitmain Antminer S17 ASICs. Step-by-step solutions to resolve mining errors efficiently.

Bitmain Antminer S17 ASICs are widely used in cryptocurrency mining operations. However, encountering errors like “Chain lacks chips” can disrupt mining activities. In this blog post, we will provide you with a step-by-step troubleshooting guide to help you resolve this issue and get your Antminer S17 back up and running efficiently.

Troubleshooting Steps to Fix “Chain Lacks Chips” on Bitmain Antminer S17 ASICs

  1. Search the kernel log for any ASIC or hashboard-related error messages. Look for messages such as “check_asic_number_with_power_on”, “killall_hashboard: power off hashboard” or “find 16 asic, times 0”.
  2. Check to see if the miner is receiving enough power from the power supply and that it is operating properly. A multimeter can be used to check the power output of the power supply.
  3. Verify that all IO cables and connections are secure and free from loose or damaged cables.
  4. If the aforementioned measures are unsuccessful in fixing the issue, you will need to perform hashboard level repairs because the issue is probably due to a defective ASIC chip or hashboard.
  5. Start by turning off the Antminer S17 apparatus. Prior to beginning, make sure it is unplugged from the power source and all other connected devices.
  6. Open the Antminer S17’s case after turning the device off. In order to prevent harming the internal components, this should be done carefully.
  7. Check the chip circuits to see which ones are affected by the chain’s lack of chips.
  8. The troublesome hashboards should be disconnected from the appropriate connectors and taken out of the case.
  9. Using a multimeter, measure the voltage and resistance of the No. 16 and No. 17 chips’ five signals (CLK-CO-RI-BO-RST) and compare them to the resistance of a typical chip. This will make it easier to pinpoint the particular flawed chip that needs to be swapped out for the flawed BM1397 ASIC chip.
  10. Replace the damaged parts with new ones, then firmly reattach them to the appropriate connectors.
  11. Once the replacement is complete, the Antminer S17’s casing should be closed before turning it back on.
  12. Before using it or making the usual configuration changes, give it some time to fully boot up.
  13. You can use your Antminer S17 if the chain’s chip issue has been resolved. If it continues, though, you might want to get in touch with a qualified technician who can find and fix any underlying problems with the gadget.


Encountering the “Chain lacks chips” error on your Bitmain Antminer S17 ASICs can be frustrating,  but following the steps outlined in this troubleshooting guide can help you resolve it. By carefully examining the kernel logs, checking the power supply and IO cables, and performing hashboard level repairs, you can get your mining machine back up and running as soon as possible. However, if you have followed all the steps in this guide and still require assistance, it is recommended that you seek the help of a professional technician.
