Antminer S17 Pro hash board detection shows "lack of ASIC chips" or "ASIC = 0"

Antminer S17 Pro hash board detection shows "lack of ASIC chips" or "ASIC = 0" Antminer S17 Pro hash board test shows "a lack of chips" Troubleshooting method : Adjust the Fluke 17B+ multimeter to the DC gear, test according to the chip number reported by the computer, and test the voltage of the five signal test points corresponding to the chip (CLK-CO-RI-BO-RST). For example, a single S17 Pro hash board has 48 BM1397 ASIC chips. When the test fixture only detects 15 chips, it will display: asic num=15; then, it is necessary to test whether the voltages of chips 15 and 16 are normal. 2. Antminer S17 Pro hash board test shows "asicNum = 0" Check method : 1. Swap the faulty hash board data cable with the non-faulty hash board data cable (only the side of the hash board is exchanged), and eliminate the problem of the data cable and the control board. If it cannot be solved, the hash board is broken. At this time, it is necessary to use a test fixt

How to troubleshoot the hash board not starting?

How to troubleshoot the hash board not starting? There are many reasons for the hash board not to start, among which the failure of the temperature sensor chip is one of the reasons for the hash board not to start. The temperature sensor chip is mainly used to sense the temperature of the hash board and its surroundings. Therefore, if it is damaged, it will cause abnormal temperature readings: the hash board will not start when the temperature is too low (the backstage log shows that the temperature sensor reading failed), or the hash board will stop running when the temperature is too high. If the temperature sensor chip fails, it can cause frequency, temperature, and hash rate failures and ultimately render the miner inoperable. Among them, the T451 temperature sensor chip is mainly used to replace the temperature sensor chip of the Antminer T17 / S17 / T9 hash board. Plenty of T451 temperature sensor chips: Troubleshooting methods : 1. The temperature sensor problem is caused by vi

Why need to replace Antminer S9 hash board temperature file?

Why need to replace Antminer S9 hash board temperature file? When testing the Antminer S9 hash board, the test fixture shows "Cannot open kernel log to change to next voltage and frequency", what should we do? Sometimes when we use the Antminer test fixture to test Bitmain Antminer S9 hash board, the test may not be carried out smoothly due to the temperature file error. This is because the S9 hash board has 3 different versions of temperature files. When the test fixture shows "Cannot open the kernel log to change to the next voltage and frequency", we need to replace the temperature files and let the test fixture work normally. You can download it on ZEUS MINING website: Antminer S9 hash board temperature files After download and open it. We will see there are three versions of temperature files. We need to copy the files to the test fixture TF card which have the S9 fixture files and replace them. Notice: We don’t know which one is correct. So we need to replace

How to use the fluke multimeter to test the IC chip failure?

 How to use the fluke multimeter to test the IC chip failure? This article will introduce five methods for measuring faulty IC chips with a multimeter, and you can check them one by one. I. Offline detection Measure the positive and negative resistance values between each pin of the IC chip and the ground. Compare this with a good IC chip to find the point of failure. II. Online detection 1. Detection method of DC resistance Same as offline detection. But beware: a. Disconnect the power supply on the circuit board to be tested; b. The internal voltage of the multimeter shall not be greater than 6V; c. When measuring, pay attention to the influence of the periphery. Such as electronic components connected to IC chips. 2. Measurement of DC working voltage The measured DC voltage of each pin of the IC chip can be compared with the normal value. But also note: a. The multimeter must have a large enough internal resistance, and the digital multimeter is the first choice; b. Each potentiomet
