Why use graphics card to mine

compared with CPU, GPU is used for general purpose calculation. So it can stack hundreds of stream processors awesome. Each stream processor is like a small CPU. Although its ability to run complex programs is far from the power of CPU, it can not support many processors, so the actual performance, especially the single precision floating point performance is much stronger than that of CPU. p> However, as we have mentioned before, a card is very suitable for general computing such as virtual currency because it has many stream processors, and the speed of obtaining specific solutions is much higher than that of N card. Therefore, many miners rush to buy a card to calculate virtual currency for profit

of course, with NVIDIA's Pascal graphics card, n card's ability in mining virtual currency is not as different as a card before. So in the current situation that a card is generally out of stock, those mid-range N cards have become the second choice for miners

What are the disadvantages of mine card

finally, I want to talk about why we can't choose mine card when we are shopping for second-hand cards. Because the miners are mining bitcoin, the most important thing is to seek profits. Therefore, the graphics card they use is running and calculating all the time, and its strength is far greater than that of daily game applications. In other words, running such a calculation for one day is equivalent to running a graphics card for one month

in addition, the places where virtual currency is mined are mostly the places where multiple graphics cards gather. Thousands of graphics cards are constantly calculating in a room, and their heat is also quite huge. Miners can not choose the chassis with good heat dissipation conditions like ordinary consumers, so that the heat can be released smoothly. In this way, the graphics cards can still operate for 7 * 24 hours under high temperature conditions, It also deepens its aging degree

the result of doing so is that the graphics cards used for mining are lost prematurely. If you buy these graphics cards, the result will be unstable operation, restart and other things will continue to happen

moreover, at present, manufacturers also have strict requirements on mine cards, such as banning second-hand sales and shortening the shelf life. If users buy these mine card graphics cards, future maintenance will also be a big challenge

2. He's using a special chip

3. As long as it is a regular digital currency, there is an electronic wallet to download

for example, bitcoin, lightcoin, gold card, reborn coin, doggy coin, lightcoin, Ruitai coin, bitstock and other digital currencies can be downloaded from rich packages
but there is no wallet to download MLM or some direct selling coins
for example: Baichuan coin, Morgan coin, treasure coin, etc.

4. Under x240, FN + ESC can be used to enable and disable FN locking function
after the FN locking function is disabled: the FN locking indicator is off. To use the special functions of each key, press the function key directly. To enter F1-F12, press the FN key and the corresponding function key. After the FN locking function is enabled: the FN locking indicator is on. To enter F1-F12, press the function key directly. To use the special functions of each key, press the FN key and the corresponding function key
hope to help you!!!

5. This is legal in some countries, and the domestic attitude is not very clear. Anyway, it is not illegal

6. Must be a card, 7850, 7870, 7950 three cards, cost-effective the fastest. Now it seems that mining is not so popular. I don't see this kind of discussion again

7. If you mean that the motherboard integrates graphics cards to dig bitcoin, first of all, you can theoretically dig bitcoin. Second, considering comprehensively, your input and output are negative. That is to say, if you invest 2000 yuan (motherboard, CPU, electricity), you get 10 yuan bitcoin
if you just want to practice the use of mining software, you can. If you want to make a profit, you can't.
