1. No matter what kind of computer, noise is basically a fan problem. If you can't clean up the st on the fan, replace it
2. 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>

3. Some mining machines can be equipped with water cooling, mainly to ensure that the operating environment ventilation, temperature is not higher than 40 degrees Celsius
4. Xinjiang bit continental machine room uses Jiafeng negative pressure fan to replace indoor hot air with outdoor cold air, and the effect is good.
5. Use your brain to know that the fan can't mine... Graphics card has powerful parallel computing power, which is much more efficient than CPU when it is used to mine. In the past, many people used to mine with graphics card, resulting in the high price of a card. But now,
bitcoin is collapsing. No one is digging. In the later stage, people didn't have to dig with graphics cards. They used specially designed circuits and quick miners. They couldn't even earn their electricity bills.
6. For example, if the computing power of bitcoin increases by 25% every month, or the revenue of each miner decreases to 80% of last month, and you book a miner at the price of 10 bitcoin that you can get five months later, according to the current situation, the miner can dig four bitcoins every month and 20 in five months, which is enough to recover the cost of miner and even double the revenue. But in fact, your miner will arrive five months later. You can only dig 1.31 bitcoins in the month of arrival, and 1.05 bitcoins in the next month. Keep digging, and you'll get 6.55 bitcoins, which means you'll never get back the cost<
you need to have specific questions and algorithms to
change the bitcoin miner into a decryption device
. If these questions are not clear, they cannot be answered
7. You need professional chips to assemble mining machines. If you want to buy chips, I suggest you buy Avalon's third generation chips directly. But the assembly of mining machine is a very troublesome thing, the technical requirements are higher, but if you do not have professional technical strength, it is recommended that you buy mining machine directly. If you want to be an OEM, you can directly buy chips and other materials for assembly. At present, avalon3 is about to be put into the market. It is suggested to buy avalon3 directly.
8. How much can bitcoin dig in a day
9. How much is the miner? Now online that mining machines are in the loss of electricity charges? is that true?
