The calculation power of mine card

1.

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

2.

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

3. Because mining does not belong to the scope of normal use of graphics card, it's good to guarantee you for 3 months. Now as long as it is detected that it is a mining card, it generally refuses to guarantee directly. If you want to mine, you should be prepared to take risks

4. Second hand graphics cards are almost all store insurance. As for the problem of closing stores, you can see that some old stores are very high-grade, and it's not cost-effective to close them. You should pay attention to the low-grade ones. You don't even have the drill. It's normal for you to run around in a wave.
and although you think that the 3-year insurance is very good, in fact, there's nothing wrong with the cards you dare to take out and sell, they still have no problem after testing. Mine card is not every mine slag, mine card 470 used for a year, 580 half a year of friends, are now zizizi. It depends on how long you dig and what money you dig
and even if you are given three-year insurance, the price they charge for this card is very low, and after three years, the price will certainly be lower, and you won't lose money. The average price of a one-year video card is more than 100 yuan, which is also included in the calculation

5. How to do the traditional futures contract, how to do the digital contract

take tradition as an example, if you think soybeans will fall, you will sell the put contract, and if you really fall, you will earn. Similarly, if you think digital currency or bitcoin will rise, you will buy the bitcoin bullish contract, and you will earn when bitcoin rises
in addition to investment, the contract also has the function of hedging. For example, if you have 10 bitcoins and you are worried that they will depreciate in the future, you will buy the equivalent bitcoin put contract. If they do fall, your bitcoin will shrink, but your contract will make money, so as to achieve the function of hedging
finally, I would like to remind you that digital currency contracts are different from traditional contracts. There are four major exchanges in traditional contracts, and there are no such problems as running away and being unprofessional. However, digital currency is different, and position crossing and position bursting occur frequently. As far as I know, the margin system of Fangtu FOTA completely rivets Credit Suisse and OCC. You can refer to it

6. The most important thing to buy a second-hand card is to ask the other party to provide the invoice or packing box at the time of purchase. In addition, do not have a card with warranty record. The appearance of the graphics card itself is good (for example, all kinds of circuit components are good) and a little st is OK (you can bargain with the other party according to this). There is nothing else
it's better not to buy a mine card. Although it's cheap, the mine card displays 24 hours a day and is overloaded. Even if it's all right with you, the mining will accelerate the aging. It may not be long before the situation occurs frequently, until it's scrapped!

7. Now, all major manufacturers have introced a new warranty policy. As long as the graphics card is confirmed to be mining, it is only guaranteed for one year. In addition, if you buy a graphics card, you need to provide an invoice to guarantee it. Therefore, you'd better not buy a mining card. You need to buy your own graphics card, ask for an invoice and register an account on Gigabyte's official website to facilitate the warranty,

8. Hello, this is not mine card, no one will take gtx750 to mine, that has to pay. In addition, the price is also very general. You can find the second-hand gtx950 at leisure. There are gtx960 2G for more than 300 and gtx1050 2G for about 400, which is much better than this

9. There is no difference. All the cards used for mining are a-cards, that is, different types of user level graphics cards. The same type of a-card, no matter whether it is a mine card or not, has no difference in performance, but the mine cards have been used in transition, and the quality can not be guaranteed

10. Since it's a licensed proct and can be guaranteed until July 2020, it doesn't matter whether it's a mine card or not. Anyway, there is a warranty. Even if there are hidden dangers, you don't have to worry if it's broken.
