Video card to mine
Computer graphics card mining: refers to the process of mining bitcoin with computer graphics card
video card mining is a formula with many answers. Users download the decoder from personal computer and then run a specific algorithm to decode it. After communicating with the remote server, they can get the corresponding bitcoin. The more powerful the graphics card is, the faster the decoding speed is, and the faster bitcoin will be g. It's also called mining

for mining machines, the most important thing is the graphics card. Generally, you can choose the most basic motherboard that supports 6 graphics cards, and later you can choose the more complex motherboard that supports more than 12 graphics cards. The specific suggestions are as follows:
1. CPU - CPU can choose the most basic and cheap CPU, as long as you can bring the system up normally, Generally, you can choose Intel's g3900 CPU with a unit price of about 200 yuan< Operating system is too laggy. If you use 6 graphics cards, you need at least 4G of memory. If you are 12 graphics cards, the windows operating system needs at least 8g of the memory. Otherwise, the system will be very stuck and then can not work normally. The Linux operation system can be 4G memory. < br > />2.
3. Motherboard - it is recommended for novices to directly choose the special mining motherboard of Yingtai series. The models are tb250 BTC with 6 card slots and tb250 btcpro with 12 card slots, as well as H81 series motherboard of Huaqing
4. Hard disk - SSD hard disk is needed for hard disk, because the reading speed is fast, and virtual memory needs to be set. SSD hard disk can improve some performance theoretically. If you use Windows system, you need at least 64GB, and Linux system can use 16GB
5. Operating system for windows, it is recommended that win10 system, corresponding to NVIDIA series and AMD Series graphics cards, can recognize up to 8 cards respectively. If the motherboard of 12 cards needs N cards and a cards to be mixed, then we can make full use of the motherboard graphics card slot
6. Graphics card - the mainstream mining graphics card models are amd Series graphics cards rx470, rx570, rx580, NVIDIA Series graphics cards gtx1060, gtx1070 and so on. It is recommended to choose 4G or more memory, and 8g is the best.
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
bitcoin does not rely on the issuance of specific monetary institutions, and is generated through a large number of calculations of specific algorithms. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction
the bitcoin system is composed of users (users control the wallet through the key), transactions (transactions will be broadcast to the whole bitcoin network) and miners (the blockchain is generated by competitive computing to reach a consensus at each node, and the blockchain is a distributed public authoritative account book, including all transactions in the bitcoin network)
bitcoin miners manage the bitcoin network by solving the problem of workload proof mechanism with certain workload - confirming transactions and preventing double payment. Because hash operation is irreversible, it is very difficult to find the random adjustment number of matching requirements, which requires a continuous trial and error process that can predict the total number of times
when a node finds the solution matching the requirements, it can broadcast its results to the whole network. Other nodes can receive the new data block and check whether it matches the rule. If other nodes find that they really meet the requirements (the operation target required by bitcoin) by calculating the hash value, then the data block is valid, and other nodes will accept the data block
The first step in setting up mining equipment is to choose the right hardware. This article will focus on GPU (graphics card) mining, of course, you can use CPU or ASIC equipment mining. Amd graphics card architecture is very beneficial to mining. NVIDIA card is not suitable for mining because of its low hash rate. The best NVIDIA graphics cards are less than 0.5 megahash. Notebook Hardware mining is not as good as NVIDIA card, which is a bad option for mining. You need to use a desktop system for mining. There is a desktop system to ensure adequate cooling of the hardware
the graphics card or card needs to be able to match the motherboard, and the power supply must have enough PCI-E connectors. Before determining the graphics card, pay attention to these. In order for the system to cool down sufficiently, you need to remove the cover of the chassis in order to get better heat dissipation. This is what people call "open air rig.". If you can aim the system at a fan or air conditioner, you can make the device cooler when it's running, thus extending its life and keeping it efficient
in short, mining is to use the chip to carry out 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
take a popular example:
I write a string of numbers on a piece of paper and give some hints. Whoever guesses correctly will be given a bonus (mining)
smart people can make more guesses (calculation ability)
some people pay money to invite many people to come back and guess together (mining)
some people call everyone together to guess, no matter who guesses, Distribute the bonus (mine pool) according to the proportion of guessing times of each person
the rest is too long, you can search by yourself...
the mining efficiency of a card is much higher than that of N card
CPU I suggest you use i7
3970
,
power supply I suggest you use 1500W
according to this efficiency, you need to dig for about two and a half years to get back the cost.
you need to buy multiple PCI e motherboards, one motherboard needs 6 cards, the power supply needs to be rated above 1000W, the CPU has enough al cores, the memory is 4G, and the graphics card needs gtx1060 or AMD rx470 / 570 or above a card
just download the mining software to start
however, if you calculate the cost, one card needs 3000, six cards need 18000 or more, at least 500 power supplies, CPU 300, memory 300, motherboard and PCI extension cable need about 800, and one monitor. In this way, a simple mining machine will cost more than 20000, and the average power consumption of a graphics card is 200W (n card level, a card 250W). Six of them are 1200W. The whole machine has this power. One hour is 1.2 kwh, and one day is full load. The electricity charge of 16x1.2x0.6 + 8x1.2x0.3 = at least 17.85. Although using a card is more efficient, it costs more electricity
a miner can earn 100-200 yuan a day. How long will it take to recover the cost? Can the value of money still be at this level at that time?

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
