2. 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.

3.

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

extended data:

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

4. N card directly ignores
a card, that is to say, it depends on the frequency and SP
,
the better the a card, the stronger the mining.

5. 1. Mining damage cannot be guaranteed
2. If the video card is used as a special test purpose, the proct is abnormal or damaged e to the over frequency of the core and memory of the video card (for example, if the core and memory of the video card are damaged e to mining and debugging, the warranty is 3 months, and it is only repaired but not replaced and not returned within 3 months from the date of shipment)

6. Try Tencent computer housekeeper killing protection, from version 4.5, the introction of international leading local killing engine, greatly improve the ability of Trojan killing. After you install the computer manager, the al engine mode is turned on by default. When you kill the virus, you decide to upgrade the al engine mode. If you want, you can easily experience the powerful al engine killing ability of Trojan horse
you can find some operation methods in the al engine area under the main interface of computer housekeeper Trojan horse killing. You can turn on or off the al engine freely, or check the update of virus database manually.

7. 1: It's authentic. Dilanheng will display ATI AIB when using gpu-z, but Luda can't recognize it. The hardest hit areas for counterfeiting are ASUS and miserable red
2: it's not necessarily that the card is easy to break, but it's used longer than ordinary graphics cards. It's too shabby to mine with 6770. It's very unlikely
3: normal.
