How to calculate the number of mining graphics cards
21.5 * 3600 seconds * 24 hours = 1857600 M / day
1857600 / 1024 / 1024 = 1.7715 T / day
a t of computing power / day can dig bitcoin worth 4.03 yuan
1.7715 * 4.03 = 7.14 yuan / day
since 2017, bitcoin has reached new heights. Yesterday (May 23), the value of bitcoin broke through the ￥ 16000 mark, hyping virtual currency, becoming a matter that the general public can participate in, And a little bit of technical level, both fried money, but also began to have the technical content of mining
as we all know, virtual currency has a numerical peak, the more difficult it is to dig. In fact, it's hard to judge whether to lose money or not if we continue to dig. Therefore, in the end how to dig, dig what can be the fastest back to this, this paper studies the above two core issues based on the current market situation
Generally, there are professional graphics cards to mine, and the 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
the graphics cards and mine cards are usually ATI chips. The bitcoin market is not good, so the miners take out their mining cards and sell them as second-hand
what is mining
to put it simply, mining is to use the chip to perform a calculation related to the random number, and get the answer in exchange for a virtual coin. Virtual currency can be exchanged for the currency of each country through some way. The stronger the computing power, the faster the chip can find this random answer. Theoretically, the more virtual coins can be proced per unit time. Because it's about random numbers, you can only get rewards if you happen to find the answer. It's possible that one chip will find the answer in the next second, or ten chips won't find the answer in a week. The more chips compute at the same time, the easier it is to find the answer, and the mining machine with built-in multi chips appears. And a number of mining machines to form a "mine" at the same time mining is to improve efficiency. In the mine pool, multiple "self-employed" join an organization to mine together. No matter who finds the answer and digs out the virtual coin, everyone gets the corresponding reward according to the calculation ability of contribution. This way can make the income of "self-employed" more stable
relationship between mining and graphics card
the stronger the computing power of ant miner, the easier it is to dig out virtual coins. Accordingly, when the more virtual coins are g out, the difficulty of mining will be increased accordingly, so as to control the yield of virtual coins. The virtual currency is not unlimited. The total number of bitcoin is 84 million
a card, that is to say, it depends on the frequency and SP
,
the better the a card, the stronger the mining.
Graphics card mining is a process of increasing the bitcoin money supply
the reason why the graphics card is used is that mining is actually a competition of performance and equipment. The mining machine is composed of graphics card array. 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
computers have professional mining chips, and most of them work 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
extended data
the difference between mine card and ordinary graphics card
the most essential difference between special mine card and ordinary graphics card is whether there is a display interface, some have no or only one interface, and other mainstream HDMI, DVI, DP HD interfaces have been castrated, so they can only be used for mining, not suitable for playing games
the special mine card is only equipped with PCI-E 1.1 because it only aims at the general calculation application of mining with low bus bandwidth requirements × 16 interface, and the ordinary game graphics card is equipped with a higher specification of the mainstream pci-e2.0 / 3.0 specification
to see if the core is yellow, some parts of the new card 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 and burnt yellow caused by high-frequency use of heat for a long time
up to 7 cards can be mined by expansion card.
Mini excavators with the weight of less than 6 tons, small excavators with the weight of 6-15 tons, medium excavators with the weight of 15-30 tons, large excavators with the weight of 30-150 tons, and super large excavators with the weight of more than 150 tons. Sany Heavy Instry has more than 200 tons of super large hydraulic excavator
the three most important parameters of excavator are operating weight (mass), engine power and bucket capacity. Common excavator structures include power device, working device, slewing mechanism, control mechanism, transmission mechanism, walking mechanism and auxiliary facilities. The transmission mechanism transmits the power of the engine to the hydraulic motor, hydraulic cylinder and other executive elements through the hydraulic pump, and promotes the action of the working device, so as to complete various operations
the materials excavated by excavators are mainly soil, coal, silt and soil and rock after pre loosening. From the development of construction machinery in recent years, the development of excavator is relatively fast, excavator has become one of the most important construction machinery in engineering construction
extended data
there are two common excavator driving modes: internal combustion engine driven excavator and electric drive excavator. Among them, electric excavator is mainly used in plateau hypoxia and underground mine and some other flammable and explosive places
according to the different scale, excavators can be divided into large excavators, medium excavators and small excavators
according to the different walking modes, excavators can be divided into Crawler excavators and wheel excavators
According to different transmission modes, excavators can be divided into hydraulic excavators and mechanical excavators. Mechanical excavators are mainly used in some large mines According to the use, excavators can be divided into general excavators, mining excavators, marine excavators, special excavators and other different categories According to the bucket, excavators can be divided into forward excavator, backhoe excavator, dragline excavator and grab excavator. The front shovel excavator is mostly used to excavate the materials above the surface, and the backhoe excavator is mostly used to excavate the materials below the surfacethe ordinary host you can match casually can't dig enough electricity.
