The graphics card used by the bitcoin mining machine
bitcoin mining machine is a kind of computer used to earn bitcoin. This kind of computer generally has professional mining chips and works in the way of burning graphics card, which consumes a lot of power. One of the ways to get bitcoin is that users download software from personal computer and run specific algorithm
to get corresponding bitcoin after communicating with remote server. The popular digital currencies in 2013 include bitcoin, Leyte coin, zeta coin, pennies (Internet), invisible gold bar, red coin, pole coin, BBQ coin and prime currency. At present, hundreds of digital currencies are issued all over the world
< H2 > extended data:in fact, there are many kinds of mining devices. As a newcomer, we recommend guiminer, which is small and easy to use. It can support CPU, oepncl, CUDA and other computing modes, so that your device, including CPU and graphics card, can achieve the maximum performance and get bitcoin more quickly
mining machine needs top-level a card support
your n card can't do it
Yes, it's said that we can dig Ethernet coins, because the power consumption is low, the computing power is good, and the price of a single card is cheaper

the so-called mining card is the graphics card for mining. The "mining" here is virtual mining. Generally, there are professional graphics cards to mine. The mined mine is actually bitcoin. Users download the mining software from the computer and then run a specific algorithm to get the corresponding bitcoin after communicating with the remote server, So the damage to the graphics card is great
many people may be confused when they hear about the mine card. What is the mine card? Do you have a shopping card? Don't worry. I'll tell you what the mine card means<

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. The mined mine is actually bitcoin. Users download the mining software from the computer, run a specific algorithm, and communicate with the remote server to get the corresponding bitcoin. They usually work by burning the graphics card, So the damage to the graphics card is great

how to judge whether the graphics card is mine card or not
first of all, look at the brand of graphics card. At present, 99% of the graphics cards mined in the market are amd graphics cards, and they are high-end graphics cards, because only a card can mine fast!!! So the low-end graphics card or others, such as NVIDIA is mine card, may only have P106, this is for the 90 day warranty. Buy graphics card, especially second-hand graphics card, must bring invoice can guarantee, this through Sn can check, what store guarantee 80% is mine card. Must be in the insurance and can be off-site insurance will be genuine. Look at the number of graphics cards taken out by the seller, especially those on salted fish. There is no doubt about the number of 3 or even 10 cards taken out for sale at a time. There is no doubt that the general user has 2 cards at most. To see if the core is yellow, some of the new cards will be light yellow, but at that time, the color of the protective paint is yellow, while the core yellow of the mine card is yellow caused by long-time and high-frequency use of heat and oxidation, burnt yellow! And most areas of PCB are yellow

the mining environment of most mine owners is relatively bad. Not only the indoor temperature is high, but also the mining machines are densely placed. In this way, the heat generated by the graphics card when it works at full load can not be well distributed, and the service life of the graphics card will be greatly shortened if it works in a high temperature environment for a long time. It is difficult to guarantee the quality and stability. After a long time of mining, the life and stability of the graphics card can only be said to depend on the character. And because the working environment of the mine card is relatively closed, even if the graphics card has been working for a period of time, it looks very good. Maybe some players will give up their worries when they see the almost new fineness after they buy the mine card. But in fact, the fineness of the mine card does not represent the remaining life. The core of the graphics card, as well as the video memory and power supply are blocked by the radiator, so don't be cheated by the appearance of the mine card.
moreover, some 7850 once worked as miners, and their life span is a problem
if you like AMD, you can buy R9 370 4GB, which is better than 7850 in performance and less than 1000 yuan in price. 750ti new also want 800 or so, some non-public version more than 800
if you don't play large stand-alone, then 750ti is enough. If you play, I don't think you can buy 750ti 7850. A second-hand gtx660 or gtx760 is also a good choice. They can't be miners
The performance of graphics card gtx660 is higher than that of gtx750ti, because gtx750ti is an upgraded version of gtx650ti, which is used to replace gtx650ti, not gtx660. The performance of gtx750ti and gtx660 can be seen as follows:
1. From the perspective of video memory frequency, gtx750ti video memory frequency is 5400mhz, gtx660 video memory frequency is 6008mhz, gtx660 is about 10% higher than gtx750ti
In terms of the number of PCs, gtx750ti has 640 stream processing units, gtx660 has 960 stream processing units, and gtx660 is better The gtx750ti and gtx660 are both 2G in terms of video memory specifications, and there is no difference In terms of power consumption, gtx750ti is 60W, gtx660 is 140W, gtx660 is more powerful and powerful In terms of bit width, gtx750ti is 128 bit gddr5, gtx660 is 192 bit gddr5, and gtx660 is betteralthough the performance of gtx660 is better, it uses older process and technology and consumes a lot of power. The power consumption is about 140W, so the power supply of this graphics card is mostly two 6p or two 8p
The performance of gtx750ti is weaker than that of 660, but the manufacturing process is advanced. The newly designed architecture makes the power consumption of this graphics card controlled at about 60W. The cooling of this level of graphics card is simple, and the radiator with two heat pipes is enough. Power supply design requirements are more simple, basically single 6p power supply, indivial graphics card does not even need external power supply
