External display card mining

1. All kinds of notebook configurations are basically not up to standard, and there is also the problem of good heat. So mining equipment is the first to eliminate NV graphics card. Mining must be done with graphics cards. CPU is not very important. But it should not be lower than i5. The difference between the overall structure of mining equipment and ordinary PC machine is the number of graphics cards. You can install 4 or 8 pic extensions. Of course, you think it's enough for two, one is OK. After expansion, you need to make your own expansion shelf. To fix the graphics card and other equipment, we need to get some fans on the shelf to cool the graphics card
are you still thinking about mining these days? This is not the year of 2010. Now, don't think about making money from small-scale mining, unless you have a multi million investment. Now, it's large-scale mining with mining machines, and professional management of the whole computer room. Now, there are several ways for personal investment. 1. Buy BTC by yourself. 2. Futures trading. 3. See ipo4. It's hard to get back the capital even if you buy butterfly mining machines by yourself. According to the current price and difficulty of mining machines, mining machines are generally expensive It takes three months to get back the capital (not including electricity, but only mining machine money). But don't forget that the difficulty has been increasing, so you can't get back the capital in your personal mining life. A better way is to buy the power stock through IPO. If you don't say that, you can talk to me about mining teaching as follows http://cnbtcnews.com/bitcoin-study/what-is-bitcoin/bitcoin-from-beginner-to-master.html

2. Copied:
in short, mining is to use the chip to carry out a calculation related to the random number, and get the answer in exchange for a virtual coin. virtual currency can be exchanged for the currency of each country through some way. The stronger the computing power, the faster the chip can find this random answer. Theoretically, the more virtual coins can be proced per unit time. Because it's about random numbers, you can only get rewards if you happen to find the answer. It's possible that one chip will find the answer in the next second, or ten chips won't find the answer in a week. The more chips compute at the same time, the easier it is to find the answer, and the mining machine with built-in multi chips appears. And a number of mining machines to form a "mine" at the same time mining is to improve efficiency. In the mine pool, multiple "self-employed" join an organization to mine together. No matter who finds the answer and digs out the virtual coin, everyone gets the corresponding reward according to the calculation ability of contribution. This way can make the income of "self-employed" more stable
take a popular example:
I write a string of numbers on a piece of paper and give some hints. Whoever guesses correctly will be given a bonus (mining)
smart people can make more guesses (calculation ability)
some people pay money to invite many people to come back and guess together (mining)
some people call everyone together to guess, no matter who guesses, Distribute the bonus (mine pool) according to the proportion of guessing times of each person
the rest is too long, you can search by yourself...

3. Bitcoin mining machine [1] is a computer used to earn bitcoin. This kind of computer generally has professional mining chips and works in the way of burning graphics card, which consumes a lot of power. It is one of the ways to get bitcoin that users download software from personal computer and then run specific algorithm to get corresponding bitcoin after communicating with remote server
the popular digital currencies in 2013 include bitcoin, Leyte coin, zeta coin, pennies (Internet), invisible gold bar, red coin, pole coin, barbecue coin and prime currency. At present, hundreds of digital currencies are issued all over the world.

4. Yingtai's tb250 BTC has an m.2 key m interface, so it can be connected to PCI-E devices. With ngff m.2 to PCI-E x16 slot adapter card, it can be connected to the graphics card. Moreover, with its original six PCI-E slots, Yingtai's tb250 BTC can realize 7-Card mining, and the bandwidth does not affect the computing power of the graphics card at all. And the motherboard's own workmanship and power supply are quite excellent, mining stability performance is also good.

5. If you are a novice, I don't recommend taking this, because the risk is very big. And the efficiency of self-employed is very low
you need to buy multiple PCI e motherboards, one motherboard needs 6 cards, the power supply needs to be rated above 1000W, the CPU has enough al cores, the memory is 4G, and the graphics card needs gtx1060 or AMD rx470 / 570 or above a card
just download the mining software to start
however, if you calculate the cost, one card needs 3000, six cards need 18000 or more, at least 500 power supplies, CPU 300, memory 300, motherboard and PCI extension cable need about 800, and one monitor. In this way, a simple mining machine will cost more than 20000, and the average power consumption of a graphics card is 200W (n card level, a card 250W). Six of them are 1200W. The whole machine has this power. One hour is 1.2 kwh, and one day is full load. The electricity charge of 16x1.2x0.6 + 8x1.2x0.3 = at least 17.85. Although using a card is more efficient, it costs more electricity
a miner can earn 100-200 yuan a day. How long will it take to recover the cost? Can the value of money still be at this level at that time?

6. 1, because the task of BTC is a very simple calculation of decryption, it does not need too many instructions. In other words, the task of BTC only needs some specific transistors to be executed

2. The CPU is used to perform mining tasks. Because the CPU needs many transistors to execute various instructions, many transistors are idle in a cycle. The speed is relatively slow

3, in order to enhance the ability of displaying images, the graphics card saves a lot of transistors that have nothing to do with the display function, so the graphics card can only display pictures, but it is much faster than the CPU in the task of displaying pictures. BTC needs to perform the same task as the graphics card, so the mining of the graphics card is faster than the CPU, So a card is more suitable for mining.

7.

The mine card is aging seriously, and its performance is lower than that of ordinary graphics card. Compared with ordinary graphics card, there are various faults

There are some differences between them: the graphics card specially designed for computing virtual currency (also known as mining) enhances the computing power of virtual currency and can run for a long time without problems compared with ordinary graphics card. But some abilities such as graphics processing and video rendering are weakened

2. There is a difference in the service life of the two: the second-hand graphics card used for mining and circulating to the trading market has the same specifications as the ordinary graphics card of the same model, but after a long time of mining, the hardware life has been greatly reced, and the purchase of this kind of graphics card may have problems at any time

extended information:

reasons for the poor cost performance of second-hand mine cards:

1. The most important thing for miners to mine bitcoin is to seek profits. Therefore, the graphics card they use is running and calculating all the time, and its strength is far greater than that of daily game applications. In other words, running such a calculation for one day is equivalent to running a graphics card for one month

2. Most of the places where virtual currency is mined are places where many graphics cards gather. Thousands of graphics cards are constantly calculating in a room, and their heat value is also huge. Miners can't choose the chassis with good heat dissipation conditions like ordinary consumers, so that the heat can be released smoothly. In this way, the graphics cards can still operate for 7 * 24 hours under high temperature conditions, It also deepens its aging degree

3. Although the price of second-hand mine card is low, the hidden danger is too big. The performance of second-hand mine card has been mercilessly squeezed by the mine owner, and its service life has been greatly reced. Moreover, because it belongs to mine card, it can not enjoy the after-sales service of the manufacturer

8. Yes, but this kind of performance has a loss, and it's very big. Other people can't do business
