How to see if the graphics card is mined

It can only be verified by time

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

3. 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

extended data:

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
