How to judge if the graphics card is mining
a mine card is a graphics card used for mining, that is, a virtual currency used for mining bitcoin or other computing proction. Because of the heavy workload and long working time, the hardware life is often shorter than that of a normal graphics card. Before 2014, only a card can be used for mining, but now n card can also be used for mining. So n card without mine card is not applicable.
1. It depends on whether the core turns yellow. Some parts of the new card will turn pale yellow, but at that time, the color of the protective paint is yellow. The core yellow of the mine card is yellow and burnt yellow caused by long-time and high-frequency use of heat and oxidation
2. Check the screw fixing plate
friends who have used independent graphics cards should know that the graphics cards are fixed on the chassis by screws, while most of the large-scale mining graphics cards are fixed by plastic ties, while the self use cards will not be fixed in this way
Interfaceinterface refers to the output interface of the graphics card. Before purchasing, you can ask the seller about the interface for connecting the display in daily use, because mining graphics cards usually do not use the display output interface
after the interface is determined, whether the interface has been used for a long time can be judged by checking whether there is st. If there is a lot of st, it will prove that the interface has not been used at all or recently

mine cards refer to the cards used to dig bitcoin. They are full loaded for a long time, with short service life and high load all day
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 a process of increasing bitcoin money supply. Mining also protects the security of the bitcoin system, prevents fraulent transactions, and avoids "double payment", which means spending the same bitcoin multiple times. Miners offer algorithms for bitcoin networks in exchange for the opportunity to get bitcoin rewards. The miners verify each new transaction and record it in the general ledgerIt can only be verified by time
Check whether the graphics card is mine card or not, you can refer to the following three points:
1, st
when the graphics card is running, it needs heat dissipation, the heat dissipation is mainly the fan on the graphics card, so the st on the fan will give us some judgment. Generally speaking, the self used video card and fan will not always run at full speed. The cotton gauze of all kinds of textiles in the room is scattered, so the st on the fan is often mixed with cotton wadding

the maintenance of the graphics card is as follows:
1. The chassis is well ventilated, which can protect the graphics card and all the hardware in the machine, and prevent the high temperature from causing the running speed to drop, crash or even burn. The machine room is hot. In summer, you can take down the side panel of the chassis to help heat dissipation, or add a fan to help heat dissipation. If conditions permit, it is recommended to use water cooling to improve the working efficiency of the graphics card
2. The interface of the graphics card and the display are connected correctly on the street, and the virtual connection is easy to be interrupted frequently or ignited, which will cause the interface of the graphics card to burn down.
3. The effect of overclocking on the graphics card is not very obvious. On the contrary, it is easy to cause a huge increase in heat and slow down or even burn down of GPU
4. Dust cleaning, no matter the Chaka or motherboard or other components, will inevitably proce st after a long time. It is necessary to remove the chassis and carry out st removal work to ensure the normal work of each component

1. It depends on whether the core turns yellow. Some parts of the new card will turn pale yellow, but at that time, the color of the protective paint is yellow. The core yellow of the mine card is yellow and burnt yellow caused by heating and oxidation after long-time and high-frequency use. Even after cleaning, there will still be yellow marks on the components, and most areas of the PCB will turn yellow
Download the gpuz test software, record the parameters, compare with the parameters of the new card evaluation on the network, see the performance parameters of the graphics card, the mine card is more or less some loss3. Whether there is st accumulation at the root of the fan, because of the characteristics of the fan, static electricity will be attracted to the center. It's hard to clean up the st at the root, because the fan is facing down and the st is less. At the same time, you can also see whether there are traces of water flow in the fan blades. The water flow will destroy the traces of st, which is a bit like the traces of mud splashing. The blower can't clean the st of the fan
4. Whether there is oil leakage around the heat pipe, because the heat conction pad of the heat pipe will leak out for a long time, and the silicone oil can not be washed out, and it will be easy to be stained with st and black when it flows out along the heat pipe

mining risk:
1. Electricity charge problem
to make the graphics card full load for a long time, the power consumption will be quite high, and the electricity charge will be higher and higher. Many professional mines at home and abroad are operated in areas with extremely low electricity charges, such as hydropower stations, while more users can only mine at home or in ordinary mines, so the electricity charges are not cheap. Even in a certain residential area in Yunnan, there was a case of crazy mining, which led to a large area trip of the residential area, and the transformer was burned
2. Hardware expenditure
mining is actually the competition of performance and equipment. With dozens or even hundreds of graphics cards of some mining machines, the cost of hardware and other costs is very high. In addition to the display card burning machines, some ASIC professional mining machines are also being put into the battlefield. Their computing power is quite strong, so it is easier to form a scale, and the electricity cost is also lower. But at the same time, the cost of these machines is also higher
3, currency security
the withdrawal of bitcoin requires hundreds of keys, and most people will record this long string of numbers on the computer, but the frequent problems such as hard disk damage will make the key permanently lost, which also leads to the loss of bitcoin
4. System risk
system risk is very common in bitcoin, and the most common one is bifurcation. Bifurcation will lead to a drop in currency price and a sharp drop in mining income. However, many cases show that the forking will benefit the miners, and the forked competitive currency also needs the miners' computing power to complete the minting and trading process. In order to win more miners, the competitive currency will provide more block rewards and handling charges to attract miners
