In 2023, is it suitable to use miners to mine or buy coins? In recent years, with the increasing popularity of blockchain technology and the rapid development of digital currency, more and more people have joined the team of mining and buying of coins. In 2023, for most people, choosing to use a miner to mine or buy coins will be a critical decision. Advantages and disadvantages of miners High power consumption, high cost, and high technical requirements are the salient features of miners' mining. But at the same time, miners also have a stable income from mining and have the advantage of controlling the speed of block verification. Here are a few viable Bitcoin miners and their profitability in 2023. Antminer S19 Pro is a miner produced by Bitmain , which is very popular in the market. It is equipped with 114 BM1398 ASIC chips , which can achieve a faster and more stable mining experience. It is estimated that the average daily income of this type of miner in 2023 will exceed 120
Antminer S19 Pro kernel log common faults and solutions
The following faults are from the backstage kernel log of Antminer S19 Pro, and other Antminer models are for reference only.
Fault 1: Temperature sensor chip fault
Solution:
1. Most temperature sensor chip failures are caused by chip soldering. Therefore, it is necessary to focus on measuring the corresponding chip's voltage and resistance value and comparing the measured resistance value with other hash boards of the same type or good hash boards. If the resistance value is abnormal, replace the faulty temperature sensor chip.
2. If the temperature sensor chip is normal, it means that the chip that the temperature sensor circuit will pass through may be abnormal.
Test method: use fluke 15b+ multimeter in DC gear and diode gear, connect the red test lead to the corresponding heat sink and test with the black test lead. Compare the measured chip data with the standard chip data. If an abnormality is found, it is recommended to replace the abnormal chip directly.
Fault 2: only find 0 asic
Chain 0 only find 0 asic, will power off hash board means that a single hash board does not detect the chip, or the hash board is not detected.
Solution:
1. First, check whether the data cable and the Antminer S19 Pro control board are faulty. Swapping the hash board cable that displays "Chain 0 only find 0 asic, will power off hash board 0" with the data cables of the other two hash boards (only the hash board side is swapped) eliminates the source of the fault.
2. Check whether the total voltage domain of the hash board is normal. If it is abnormal, you need to use a fluke 15b+ multimeter to check whether the PIC, MOS tube, and boost circuit are abnormal. For the test method, please refer to How to test the voltage and ground value of the Antminer S17 hash board?
3. Check whether the RI signal voltage is normal. Find a group of RI signals on the edge of the domain in the middle domain for detection. If it is normal, we will check it forward. If it is abnormal, check it backward.
Note: The transmission direction of the RI signal is from chip No.114 to chip No.1.
4. Check whether the voltage and ground value of the RI signal of the chip are abnormal.
RI signal voltage detection method: adjust the fluke 15b+ multimeter to the DC gear, and place the red and black test pens on the heat sink and RI of the same domain.
RI signal to ground value detection method: adjust the fluke 15b+ multimeter to the diode gear, the red test pen is placed on the heat sink in the same domain, and the black test pen is detected.
Whether the measured resistance value is abnormal can be compared with the resistance value of other chips in the same domain. If the data is abnormal, most of them are caused by chip soldering. Solder it twice first. If it cannot be solved, replace the faulty BM1398 chip.
