How to see if it's miner graphics card

1. There's no good way to distinguish, so it's better for people who don't know how to do it

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

Interface

interface 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 ledger

There are many things to experience, but they are all developing in a healthy way. Otherwise, today's bitcoin can reach 120000

in April 2017, the central bank and other seven ministries and commissions identified ICO as illegal fund-raising, called ICO to stop and announced: ICO refers to the so-called "virtual currency" that financing entities raise bitcoin, Ethereum and other so-called "virtual currency" from investors through the illegal sale and circulation of tokens. In essence, ICO is a kind of unauthorized illegal public financing behavior, suspected of illegal sale of tokens, tickets, financial fraud, etc Illegal and criminal activities of pyramid selling

for a time, the major exchange platforms have withdrawn their assets and closed down, and the currencies of the exchanges have dived, with a drop of 90%. This is the famous "94" event in the currency circle

4. 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. 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 loss

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

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

6.

there are only two ways to judge whether the card is mine card or not:

1. the most obvious sign of mine card is that the PCB on the back of GPU core turns yellow, which is caused by long-time full load work

2. get a temperature curve and run time to know if it is mining. It's only the mine that operates at such a high temperature for a long time without taking effective cooling measures

what is the meaning of graphics card

the so-called mine card is the graphics card for mining. The "mining" here is virtual mining. Generally, there are professional graphics cards to mine, and the mined mine is actually bitcoin. Users download the mining software from the computer and then run a specific algorithm. After communicating with the remote server, they can get the corresponding bitcoin. Most of them work by burning the graphics card, so the power consumption is large. Graphics cards and mine cards are usually graphics cards with ATI chips. When bitcoin went out of business, those miners took out their mine cards and sold them as second-hand ones
