Through a specific program and algorithm, using the computer graphics card calculation rate, a large number of calculations are carried out in the selected mine pool to generate data packets

2. There may be a problem. I can't say exactly what the problem is. You can go to the official and ask. The technical staff will let you know. It's not a problem. It may be low voltage or poor heat dissipation. Ant S3 mining machine is now in the phase out period, ant S5 has come out. Now mining relies on low electricity price and low energy consumption of mining machinery. Mining is not particularly profitable now.

The most advanced bitcoin mining machine, one to two years to dig out a bitcoin, bitcoin mining is now too difficult. If you want to dig, you can dig ether currency. Now it is steadily appreciating every day. According to the current development trend, it will be able to recover its capital in about seven months, and then it will be profitable< br />

4. According to the current total computing power and the current growth rate of total computing power, it will take about 250 days to dig a bitcoin

5. The ant S9 proced by bitmainland is the most mainstream mining machine on the market, which is famous for its low power consumption and high output. Ant mining machine S9 adopts TSMC's 16 nanometer FinFET process. TSMC comes from the agent factory of iPhone chip, and ant also applies the full custom design scheme on S9. So, this makes S9 have super computing power upgrade, let mining efficiency is higher. S9 adopts the latest generation chip bm1387 (189 chips in total), and the computing power of a single chip reaches 74gh / S. in terms of power consumption, S9 maintains at 0.08w/gh/s. (the power consumption is 0.08w/gh/s at 0.4V core voltage, and the power consumption per T computing power wall is only 100W, which is only 2.4 kwh per day. Rated calculation force: 13.5th/s ± 5%

Xuebao miner A1, miner chip is the core of miner. It is said that bitmine is the source of the whole bitcoin miner instry. Bitmine has its own powerful chip technology as early as the end of 2013. Of course, it also benefits from the joint cooperation and efforts of bitmine and other companies, and Xuebao miner is their own proct. A1 is the world's first customized mining machine, equipped with ASIC chip (bf16btc), the number of chips is as high as 576pcs, the computing power of a single chip is 84.1gh/s, and the overall computing power is as high as 49th / s ± 5%

Z4 adopts Intel al core [email protected] Cup, mining power is 265mh / S (ETH), equipped with independent graphics card 570x8, has 9 fans, and the radiator adopts Intel original radiator, power supply: station flag 2000W power supply, voltage: 12.4-12.6v.

6. Brother, bitcoin has collapsed. These digital currencies are deceptive, and the rise and fall of them are controlled by people. Only fixed assets or gold are relatively safe. The so-called Taiping antique gold in troubled times. But also to polish your eyes, low into.

3.5.11 of "coal mine safety regulations" stipulates that the distribution voltage at all levels of coal mine electricity and the rated voltage level of various electrical equipment shall meet the following requirements: the high voltage shall not exceed 10000 V; Low voltage not exceeding 1140 V; The rated power supply voltage of lighting, signal, telephone and hand-held electrical equipment shall not exceed 127 V; The rated voltage of remote control line shall not exceed 36 v; When 3300v power supply is used for electrical equipment in mining area, special safety measures must be formulated

extended data

the voltage grade of coal mine power supply in China is 35kV - the voltage of coal mine ground substation; 10kV or 6kV - underground power supply and distribution voltage; 3KV or 1140V - power supply voltage of fully mechanized working face and high-grade common working face; 660V - power supply voltage of mechanized mining face and excavation

380V - distribution voltage of low voltage power grid on the ground and underground of small tramcar; 220 V - lighting voltage of ground, shaft bottom yard and main air inlet roadway; 127V - power supply voltage of hand-held electric tools, lighting, signal and telephone; 36V - limit voltage of control electrical equipment; DC 250V, 550V - DC trolley power supply voltage

8. If you want to use the switching power supply of the computer for other purposes, you can change it as follows:
1. Open the iron box of the power supply, take out the circuit board from the box, and use a brush to remove the st
2. Find the key components. Including: power oscillation integrated block, optocoupler, 12V voltage regulator, pulse width adjusting potentiometer, etc. Find the information of power supply mole
3. First, change the 12V voltage regulator into 15V, and find the pulse width adjustment circuit according to the data of power supply integrated block. Some power supplies do not design power supply fine-tuning, but fixed resistance. Remove the fixed resistance, and connect a potentiometer whose resistance value is basically close to the welding resistance on the two solder joints. Now adjust the resistance of the potentiometer to the maximum
4. Use a multimeter to monitor the 12 V power supply port, turn on the power supply, slowly rece the resistance of the potentiometer, observe the voltage change, and adjust it to 15 v. After stabilization, observe for a little time and connect the false load toaster
5. After it is accurate, measure the resistance of the potentiometer and replace it with a fixed resistance with the same resistance.
