Mining graphics card refitting ordinary graphics card

1.

At present, the mining machines in the market are mainly divided into two categories, one is PC based mining machine, the other is professional mining machine based on ASIC chip

the general PC mining machine can be used as a home computer, but the CPU performance is weak and the power consumption is high. Professional mining machine based on ASIC chip can not be used as ordinary computer because it has no graphics card and does not support mainstream desktop operating system

extended data:

mining machine is one of the ways to obtain bitcoin is a kind of network virtual currency proced by open source P2P software. It doesn't rely on a specific currency institution to issue, but is generated by a large number of calculations of a specific algorithm. It uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions economically. The decentralized nature of P2P and the algorithm itself can ensure that the currency value cannot be manipulated by mass proction

any computer can become a mining machine, but the profit will be relatively low, and there may not be one in ten years. Many companies have developed professional mining machines, which are equipped with special mining crystal. They are tens or hundreds of times higher than ordinary computers

mining is actually a competition of performance and equipment. The mining machine composed of many graphics cards, even if it is just a garbage card like hd6770, can surpass the single graphics card of most users in terms of computing power

and this is not the most terrible. Some mining machines are made up of more such graphics card arrays. When dozens or even hundreds of graphics cards come together, the graphics card itself costs money. Considering the hardware price and other costs, there are considerable expenses in mining

in addition to the display card burning machine, some ASIC (application specific integrated circuit) professional mining machines are also put into the battlefield. ASIC is specially designed for hash operation. Although the performance may not be able to kill the display card in seconds, it is already quite strong. Moreover, because their power consumption is far lower than that of the display card, it is easier to form scale and the electricity cost is also lower, It is difficult to compete with these excavators. And this kind of machine will be more expensive

2. Mining for computer graphics card requirements are very high, low-end graphics card is not used, so low-end graphics card is not likely to be used to mining.

3. 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.

4. For bitcoin, I suggest adding four black hole superfrequency versions of his hd7970 to the x79 motherboard

first of all, his7970 adopts innovative black hole heat dissipation technology, which is especially suitable for multi card exchanges
another point is that n-card is not recommended. The mining efficiency of a-card is much higher than that of n-card
I suggest you use i7 3970 CPU and 1500W power supply
according to this efficiency, you need to dig for about two and a half years to get back the cost.

5. Today's bitcoin mining uses amd graphics cards, which are not very different from ordinary graphics cards. You can also play 3D games on them for design. The hd7850
1g version is the most popular. This model can well balance the mining speed and price
in other words, there are a lot of "mining machine graphics cards" on Taobao, because these graphics cards use less materials under the same core and basically unchanged hash speed, such as recing video memory to improve the performance price ratio (the size of video memory has little to do with the mining speed), which can shorten the time to recover the cost
in short, the graphics card of mining machine is the core of common high-end graphics card + the workmanship of low-end graphics card, or some cheap medium and high-end public graphics card.

6. Generally, amd graphics card has many stream processors, and mining is fast. In those years, 68707850280 (without x) was popular. Now, the new card mining is more valuable than 470d, which is worth 470 yuan. The cost performance ratio and efficiency ratio are more prominent.

7. At present, the most valuable currencies for investment are rare ancient coins, which are unnecessary for a large amount of existence, and rare commemorative gold coins issued by the state. These should have the largest value-added space, waste a lot of money, and can be collected if there is more money.

8. The information transmission of the blockchain itself may be false
1. The provincial characteristics of the blockchain, once included in the block, are irreversible and can not be tampered with, and the information is true and effective, but there is only one case that is false, that is, the information written in the first attempt is false, resulting in the false information stored in the block
2, Basically, it's the application side of the technology

1、 Different functions

1. Mine card: it's the graphics card for mining. The "mining" here is virtual mining. Generally, there are professional graphics cards for mining, and the mining is actually bitcoin

2. Ordinary graphics card: the graphics card procts used in ordinary desktop computers, that is, the most common graphics card procts in DIY market

Mine card: it emphasizes strong performance, stability and accurate drawing

2. Ordinary graphics card: ordinary graphics card pays more attention to civilian applications, and more emphasis on providing more powerful entertainment, office, game, multimedia and other performance at a price acceptable to users

Third, the situation after use is different

mine card and the same model of ordinary graphics card specifications are the same, 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

10.

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
