What's the meaning of mining 8 cards with 2 exclamation marks

1.

Simply put, it is to use your graphics card to work for others in your spare time in exchange for compensation. Only AMD's graphics card is suitable

graphics card mining to make money:

1. Determine the virtual currency to be mined

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

{rrrrrrr}

extended data

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

3. This is very simple. You can compare CPUs to PhD students, who are very good at dealing with complex problems. The stream processors of graphics cards are high school students. However, there are only a few CPU cores (for example, 8 cores), and there are thousands of stream processors for a single graphics card.
mining is actually equivalent to pasting envelopes. If you think about it, eight PhD students paste quickly, Or more than a thousand high school students
mining is to use the parallel computing function of graphics card to solve simple but huge mathematical problems

The graphics card used by the bitcoin mining machine

bitcoin mining machine is a kind of 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. One of the ways to get bitcoin is that users download software from personal computer and 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, BBQ coin and prime currency. At present, hundreds of digital currencies are issued all over the world

< H2 > extended data:

in fact, there are many kinds of mining devices. As a newcomer, we recommend guiminer, which is small and easy to use. It can support CPU, oepncl, CUDA and other computing modes, so that your device, including CPU and graphics card, can achieve the maximum performance and get bitcoin more quickly

5. It is grammatically wrong, but it can be used to increase mood in daily life, which does not exist in official documents

A number followed by two exclamation marks indicates a double factorial

double factorial with n!! Expression

when n is a natural number, it means the proct of all positive integers which do not exceed N and have the same parity with n. For example:

extended data

as early as the 12th century, Indian scholars have used the concept of factorial to calculate permutation number. In 1677, Fabian Steadman used change ring to explain the concept of factorial

after describing recursive methods, steed described factorial as: "now the essence of these methods is as follows: the change number of a number includes all the change numbers of all numbers smaller than itself... Because the complete change number of a number takes the change number of smaller numbers as a whole, And by uniting the complete changes of all numbers. "

now the general factorial sign n! It was first put forward by French mathematician Kramp (C.) in 1808, and then popularized by German mathematician and physicist Georg ohm (M.) and so on

This shows that there is something wrong with the graphics driver of the computer. Through the following operations to solve:

1

3. Download and install the required driver, and then restart
