Installation of force calculation board for ant S7 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%

2. wall power consumption: 1210 watts (bit mainland apw3-1600 watt power supply, 93% AC / DC efficiency, 25 ℃ ambient temperature)

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 ℃

9. network connection: Ethernet

2. There are many reasons for the low computing power of S7 bitcoin
1. It may be the problem of temperature. Low or high temperature will affect the calculation power of the miner
2. There are problems in the miner itself, which lead to abnormal calculation force
3. The aging of mining machine leads to the decrease of calculation power, and the calculation power of second-hand mining machine is relatively the first
bitcoin, Leyte coin, sand coin and all the mining machines that need mining are like this.

3. Yinbit is recommended. Yinbit is a maintenance brand of coin printing. It is an official quality maintenance brand established by an old maintenance team. It has five years of ant mining machine maintenance experience and has excellent strength. It can realize the quick repair of ant 17 series and apw9 / apw9 + power supply. It is one of the few maintenance brands in the instry that can quickly repair high computing power models. At the same time, it undertakes the business of rescuing S17 and T17 scrapped computing power boards, At present, there are maintenance sites in Cheng, Sichuan, Dehong, Yunnan and Xinjiang
at the same time, Shenma M20 / M21 series and p21 power supply quick repair can also realize quick repair with quality assurance because they are authorized maintenance brands of Shenma and Xindong.

4. The temperature is too high: one of the double fans is not running, or the speed cannot reach.

5. Certainly. We are members of consensys blockchain. The members of consensys blockchain mainly cooperate in expanding social impact. A number of blockchain projects are working together for the sustainable development goals of the United Nations. Aeternity is an investor in Kora. We will announce the details of the cooperation between KORA and stellar soon. Please look forward to it!

6. 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.
