DC miner

1.

It is reported that the performance of bm1385 chip is more than twice that of bm1384

The power supply scheme of S7 is similar to that of S5. The S5 + mode of dense chip arrangement is adopted, which makes the arrangement structure more compact. Under the same space, 60 chips are placed in S5 and 162 chips are placed in S7

The price of S7 is 1823 US dollars, equivalent to 11650 RMB yuan, and the delivery time is from September 21 to September 30. At the same time, the official announced the parameters of ant mining machine S7. The chip adopts bm1385, a 28nm fully customized chip independently developed by bitcontinental, with a computing power of 4.86t and a power consumption of 1201w. Ant miner S7 is the best miner with the best power consumption ratio so far, and the power per T is about 250W

official website is not open for sale at the moment. Users of early adopters can place their orders in overseas official website. The delivery address is 17% of the Chinese mainland tax and the purchase price is 13630 yuan. p>

ant mining machine S7 specification parameters:

1. rated calculation force: 4.86 Th / S ± 5%

3. power efficiency: 0.25 Joule / GH (wall, 93% AC / DC efficiency, 25 ℃) ° C)

4. rated voltage: 12V ± 5%, which should not be lower than 12.0V

5. number of single power board chips: 162x bm1385

6. overall dimension: 301 mm (L) * 123 mm (W) * 155 mm (H)

7. cooling: 2 × 12038 fan

8. working temperature: 0 ℃ to 40 ℃

4. Mining is definitely the first professional mining machine. Many new children's shoes will choose to use the graphics card to mine, but the graphics card mining is just like doing a professional job with the "magic oil", but the efficiency is certainly not high. To dig bitcoin, we should pay attention to the following points: first, computing power (i.e. mining speed), second, power consumption, and third, stable performance. Computing power, bitcoin mining is faster than problem-solving speed, so it is self-evident that speed is more important; Power consumption is directly related to efficiency, that is, the issue of cost expenditure; The stability of performance mainly depends on the stability of calculation force when the working frequency is constant. Just think about it, no one wants the miner to lose its computing power every so often, or even break down. After all, it's all money ~
the general computing power of the graphics card is a few gigabytes, while the professional miner chip is as high as several thousand gigabytes. Take bm1387, the chip with the lowest power consumption in the world, as an example, the S9's computing power is as high as 14T, the power consumption on the wall is only 1400W, and the rated computing power reaches 13.5 Th / s ± 1 J / GH + 12% (wall, AC / DC 93% efficiency, 25 ° Rated voltage: 11.6 ~ 13.0v, in addition, in the case of non independent power supply, three power calculation boards can be connected to different power supply respectively, but each power calculation board can not be connected to multiple power supply, and ensure that the power calculation board is finally powered on
among the mining machines, ant mining machine is my favorite. At the same time, based on the average investment cost of bitcoin in the early stage, ant S9 can basically recover the capital in about five months, and the income in the later stage is immeasurable.

6. Bitcoin, in short, is an internationally recognized virtual currency. In some foreign countries, bitcoin can be used to trade; In China, it was also announced a while ago that bitcoin withdrawal might be tried out
bitcoin will be released on the Internet regularly to mine. To put it bluntly, it is the process that people use computer hardware to calculate the location of bitcoin and obtain it

7. If you are a positive and enterprising investor, you can enter. If you are a steady investor, you'd better not invest. The risk of investment is too big
virtual currency is a high-risk and high-yield investment proct in China. Virtual currency has no entity support and government credit endorsement. Its price fluctuation is affected by people's psychological expectations and is easily controlled by the makers. Moreover, pyramid schemes of virtual currency are also very rampant in China, especially those new coins, which are mostly pyramid schemes. If you are interested in digital currency, you should play bitcoin, Ruitai coin, Laite coin and doggy coin, which are mainstream digital cryptocurrencies.
