Reasons for low calculation power of mine card

1. N card directly ignores the
a card. To put it bluntly, it depends on the frequency and SP
,
the better the a card, the stronger the mining.

2.

The so-called mine card is bitcoin mining graphics card. Because of the overload operation of the mine card, the life of the graphics card is shortened and the aging is serious

the bitcoin mining machine is the computer used to earn bitcoin. This kind of computer generally has professional mining chips, and works by installing a large number of graphics cards, which consumes a lot of power. One of the ways to get bitcoin is to download mining software and then run specific algorithm to communicate with remote server to get corresponding bitcoin

mining is actually a competition of performance and equipment. Some mining machines are made up of more graphics card arrays. With dozens or even hundreds of graphics cards, the cost of hardware and other costs is very high, and there is a considerable expenditure in mining

the discrimination method of mine card, Even the plastic plug is on it, so pay a little attention to it

The second is to look at the capacitance and other components on the graphics card. In essence, the graphics card is a combination of various chips and electronic components on the PCB board. In the process of overclocking and long-term use, the mine card will cause many components to turn yellow. If you carefully observe, the video memory chip will be black in yellow phenomenon, and then according to the time of the video card to judge, this will be more secure

3. There is also the mark of screw. Only a few mine cards are installed with screws. If the screw hole position of the second-hand card purchased by yourself is very new or even has no mark, you should pay attention to it

In short, mining is the use of chips for a random number related calculation, get the answer in exchange for a virtual currency. 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

In his paper, Nakamoto stated:

"in the absence of central authority, it not only encourages miners to support bitcoin network, but also enables bitcoin's currency circulation system to have the initial source of money injection."

Nakamoto compares the generation of bitcoin by consuming CPU power and time to the consumption of resources by gold mines to inject gold into the economy. Bitcoin mining and node software mainly initiates zero knowledge proof and verification transactions through peer-to-peer network, digital signature and interactive proof system

each network node concts broadcast transactions to the network. After these broadcast transactions are verified by miners (computers on the network), miners can use their own work proof results to express their confirmation. The confirmed transactions will be packaged into data blocks, and the data blocks will form a continuous data block chain

Nakamoto himself designed the first version of bitcoin mining program, which was later developed into the first generation of widely used mining software bitcoin, which was popular from 2009 to mid-2010

each bitcoin node will collect all the unconfirmed transactions and gather them into a data block. The miner node will add a random adjustment number and calculate the SHA-256 hash value of the previous data block. The mining node tries again and again until it finds the random adjustment number so that the hash value is lower than a specific target

extended data

at the earliest, bitcoin miners were mining through Intel or AMD CPU procts. But because mining is a computing intensive application, and with the continuous improvement of mining number and equipment performance, the difficulty graally increases, now using CPU mining has no profit or even loss

as of 2012, since the first quarter of 2013, miners graally began to use GPU or FPGA and other mining equipment [5]. At the same time, a large number of ASIC devices were launched in mid 2013

since July 2013, the computing power of the whole network has shown a straight-line rise e to the large number of ASIC equipment put into operation. Based on the average computing power in July 2013, all CPU mining equipment has been unable to generate positive revenue, and FPGA equipment is close to no revenue

according to the estimation of average computing power in September 2013, the existing small ASIC mining equipment developed for indivials will also be close to no positive revenue in the next 1-2 months. A large amount of computing power is monopolized by cluster ASIC mining equipment with 5 th ash / s or more. Because of no profit, indivial mining is almost squeezed out of mining groups. Some bitcoin miners have raised funds to build machine rooms and install a large number of mining equipment in places where low-cost electricity can be obtained

in order to save the cost of mining, some bitcoin miners make mining programs into malicious programs to infect other people's computers on the network to mine for themselves

4. There must be damage. First of all, only a card can be used for mining, and N card is boring for mining.
secondly, the computer needs to be running all the time and can't be turned off for mining, which requires a lot of computer. It is harmful for each part to do a lot of calculation for a long time, and it also requires high power supply for the computer
mining can't be powered off, and it needs to be recalculated after power off. Graphics card long time to do a lot of calculations will lead to greatly shorten the life of the graphics card, so their own home, do not recommend mining, mining is not as expensive as electricity

5.

Mine card refers to the graphics card used by bitcoin mining machine, mostly amd graphics card

mine disaster refers to the decline in the price of bitcoin and the sale of second-hand mine cards

bitcoin mining machine graphics card long-term high load operation, graphics card service life will be reced accordingly, so the price will be cheaper

extended data:

bitcoin mining machine is a computer used to earn bitcoin. This kind of computer generally has professional mining chips, and mostly 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

bitcoin mining started with low-cost hardware such as CPU or GPU, but with the popularity of bitcoin, the mining process has changed greatly. Nowadays, the mining activities are transferred to the field programmable gate array, and the hash speed can be achieved through optimization. The mining efficiency of this mode is very high

The mine card of graphics card is the graphics card used by bitcoin mining machine

Mining card is a graphics card that is specially used for general calculation to earn network currency "bitcoin". Bitcoin can be proced with specific programs, and then sold to people in need to be able to exchange real money, or mining for short

because this program needs a lot of repeated calculations, it is more efficient to use a card with more sp. Because of the full load operation all year round, there are many uncertain factors in the mining card

extended data:

mining is actually a competition of performance and equipment. The mining machine composed of many graphics cards, even if it is only hd6770, the computing power after "group" can surpass the single graphics card of most users

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 is a considerable expenditure in mining

in fact, there are many kinds of mining devices. Guiminer, which is small and easy to use, is recommended. It can support CPU, oepncl, CUDA and other computing modes

in this way, devices including CPU and graphics card can achieve the maximum performance, and then acquire bitcoin more quickly

Virtual currency refers to non real currency. Well known virtual currencies, such as online currency of Internet company, q-coin of Tencent company, q-point and voucher of Shanda company, micro currency launched by Sina (used for micro games, Sina reading, etc.), chivalrous Yuanbao (used for chivalrous road game), silver grain (used for bixue Qingtian game), and popular digital currencies in 2013 include bitcoin, Laite coin, infinite coin, quark coin, zeta coin, etc Barbecue coins, pennies (Internet), invisible gold bars, red coins, prime coins. At present, hundreds of digital currencies are issued all over the world. The legend of "bitcoin, Wright silver, infinite copper, pennies aluminum" is popular in the circle

network virtual currency can be roughly divided into

[1] the first category is familiar game currency. In the era of stand-alone games, the protagonist accumulates money by knocking down the enemy, entering the gambling house to win money, and using these to buy Herbs and equipment, but it can only be used in his own game console. At that time, there was no "market" between players. Since the establishment of Internet portal and community, the realization of game networking, virtual currency has a "financial market", players can trade game currency

[2] the second type is the special currency issued by the portal website or instant messaging service provider, which is used to purchase the services in the website. The most widely used is Tencent's q-coin, which can be used to purchase membership, QQ show and other value-added services

[3] the third kind of virtual currency on the Internet, such as bitcoin (BTC), lightmoney (LTC), etc. bitcoin is an electronic currency proced by open-source P2P software. Some people also translate bitcoin as "bitcoin", which is a kind of network virtual currency. It is mainly used for Internet financial investment, and can also be directly used in daily life as a new currency

[4] the application of computer communication technology and the development of Internet as a new media are the technical basis of network marketing. Internet was born in the 1960s. With the development of network protocols and related hardware and software procts, Internet has graally changed from military to commercial and civil. From the 1990s, the Internet has graally entered into the daily life of society. As a matter of fact, the Internet, as an emerging media, has developed faster than all other technologies in the past. It took 38 years for radio to reach 50 million audiences, 13 years for television, and only 3-4 years for Internet. Therefore, the Internet is considered to be the technological change that has the greatest impact on the world economy in the past 100 years

8. Aslong coin is a kind of platform subscription coin, and there is little information on the Internet. There is a netizen on Qinghai news network who said that the Internet has nothing to do with it. The news report of zhonghua.com will be deleted. This shows that there are a lot of false elements in the propaganda of this kind of currency

the risk of platform subscription currency is great, so we suggest you stay away from it. Bitcoin home has also reported similar incidents of running away from the subscription currency platform before. Subscription currency platform is small, information is not open and transparent, and it is not necessarily an open source cryptocurrency. Some platforms may gather a lot of funds on the platform and run away. They may also encounter the selling of Dazhuang, which leads to the collapse of Shanzhai coin. The development and operation team will also choose to develop a new Shanzhai coin.

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. Mov CL CNT is a statement that sends the variable CNT to the CL register, and then uses CL to control the execution times of a program. It's not to control how many times the last statement is operated, because you have to assign a value before you can use it, so it's to control the execution times of the following program. The specific location of this program is not fixed, and it can be seen according to the specific program.
