How to solve the problem that the hash board does not start on the Antminer S17 Pro? The temperature sensor is mainly used to sense the temperature of the hash board and its surroundings. If it is damaged, it will cause abnormal temperature readings, and the hash board will not start when the temperature is too low (the backstage log shows that the temperature sensor reading failed), or the Antminer S17 Pro stops running when the temperature is too high. So when the temperature sensor chip fails, you can refer to the following methods for troubleshooting. Check method: 1. Most temperature sensor chip failures are caused by chip pseudo soldering. It is necessary to measure the chip voltage and ground value with a fluke 15b+ multimeter to troubleshoot and find a hash board of the same model or another good hash board for data comparison. If the temperature sensor chip is faulty, it can be replaced directly. 2. If the temperature sensor chip is normal, the chip that the temperature senso

What is the difference between Ethereum mining and Bitcoin mining? Compared with Bitcoin mining, Ethereum mining is more niche, and fewer people know and participate. Today’s article, we help you better understand Ethereum mining by comparing it with Bitcoin mining. 1. Mining algorithm, equipment, hash rate scale Bitcoin uses the SHA-256 encryption algorithm, and when mining, the competition is the hash rate. To increase the hash rate, Bitcoin has gone through four stages CPU mining, GPU mining, FPGA mining, and ASIC mining, and the degree of specialization is getting higher and higher. Ethereum uses the Ethash encryption algorithm. It is necessary to read the memory and store the DAG file during the mining process. Since the bandwidth of each reading is limited, and the existing computer technology is challenging to make a qualitative breakthrough in this problem. Therefore, no matter how the computing efficiency of the computer is improved, the memory reading efficiency will still no

How to cool it down if the miner's temperature is too high?  Regardless of the size of the mining farm, the problem of cooling is inseparable. People are afraid of high temperatures, and so are our miner rigs. If the chip temperature is within 80, it is normal. If it exceeds 80 or too high, the chip will be damaged (and this damage is permanent), the hash rate will also decrease, will shorten the miner's life. The result is a loss of revenue. This should also be taken into consideration when choosing mining farms. How to cool down? The simplest and almost zero-cost method is, of course, to wait until it rains and enter the factory with a cool breeze, even if the temperature is high. But 365 days a year, it is impossible to rain every day. So have to think of other ways. The miner generally has basic cooling measures, including cooling fans, heat sinks, and other designs. But this is not enough. In the actual operation process, the miner runs 24/7 hours, which is also affected b

How to solve the find 0 ASIC fault on the Antminer S9j? The following kernel log faults are from the backstage of the Antminer S9J. Other Antminer models are for reference only. Solution: 1. First of all, by exchanging the data cable of the hash board to eliminate the data cable problem and the Antminer S9J control board. Operation method: Swap the data cable of the Antminer S9j hash board showing "has 0 asic" with the other two normal data cables of the hash board (only the side of the hash board is exchanged). 2. Use the fluke 17B+ multimeter to check whether the total voltage domain of a single hash board is normal. If it is abnormal, check whether the PIC, MOS tube, and boost circuit voltage are abnormal. 3. Check whether the RI signal voltage is normal (the transmission direction of the RI signal is from the last chip to the first chip). Directly find the RI signal of a group of chips on the edge of the domain in the middle domain for detection. If the voltage is abnorm

How do we avoid the trap of Bitcoin mining farm operation and maintenance? Although the people in the mining circle are low-key, it is generally recognized that there are many traps in the industry. Therefore, every link is strictly reviewed, from industrial links such as miner purchase, mining farm construction, formalities, operation, and maintenance to digital links such as platform construction, cloud hash rate sales, digital asset storage, and verification and distribution of income effectively protect the interests of users. During these processes, we have encountered various problems, especially in the early mining farm construction; land resources and power resources are two unavoidable problems. Today, I will give you a breakdown of the traps in the construction of mining farms and how to avoid them to help you mine fewer detours and mine more. Mining farm infrastructure cost Trap 1: Power resources The types of electricity are divided into hydropower, thermal power, wind powe
