Graphics card mining platform
A graphics card, a software that can earn bitcoin. Inject new bitcoin (data hashing) into the whole bitcoin market, and then the market will have a certain incentive mechanism (allocate bitcoin to you in proportion). Because if you don't get it, no one will do it, just like your computer is a miner, and bitcoin is the reward
Through a specific program and algorithm, using the computer graphics card calculation rate, a large number of calculations are carried out in the selected mine pool to generate data packets
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 graphics card market in 2017 is the most special in recent years. In the past few years, no graphics card will increase its price by 100% a few months after its release. RX 580 has achieved this goal. Together with all the graphics cards below 3000 yuan, it has broken through the premium point in an irresistible manner. All this happened with the bitcoin price breaking through 3000 US dollars. After miners swept the RMB 2000 RX 580, the price of low-end RX 560 and even GTX 1050 Ti increased to varying degrees. However, is the price directly proportional to the ability of hash algorithm? Recently, we did a test to collect the new generation of graphics cards at various prices on the market, test the mining speed of Ethernet and bitcoin, and see which card has the highest cost performance
Different from the thousand yuan market, this wave of mining tide has a great impact on high-end graphics cards. In the test results, RX 580 and Rx 480 have almost reached the bottom of GTX 1070. Moreover, the price of Rx 580 is even competing with that of GTX 1070, so the miners directly swept the 3000 yuan market when GTX 1060 3gb / 6GB is out of stock, and GTX 1070 is basically out of stock. The more advanced GTX 1080 is also out of stock, but it's not clear whether the players are forced to go directly to the high-end card or the miners extend their claws to this market. The situation of GTX 1080 ti is only slightly improved, but it's not much better. However, not everyone can afford the 6000 yuan graphics card. Only the top players will be affected, but it's just a narrower choice. It's not the case that the rich can't buy itsummary:
to mine, the first choice is the graphics card with more than 3gb video memory, which is the basis. In addition, the core frequency will affect the mining speed. We have two GTX 1080 cards on hand, one is public version, and the other is MSI GTX 1080 gaming X. the operating frequencies of the two cards are 1885mhz and 1936mhz respectively. After testing, because of the frequency, the latter will be about 4% faster than the former in actual mining. The advantages of high-frequency graphics card are highlighted
So Xiaobian's opinions and suggestions are as follows:the low-end card and the old architecture card are not suitable for mining. GTX 1080 ti is an extreme, with the most powerful performance, but the price is not suitable for large-scale procurement. The mining speed of a card with the same location is much faster than that of N card, The cost performance of GTX 1060 3gb is higher than that of GTX 1060 6GB. The frequency and the number of stream processors / CUDA have a great influence on the performance of the card. The size of video memory has no influence on the mining. It's enough. Different video cards will have different profits if they dig different coins. If you want to further explore, you need to test several currencies, Limited to space, we only select two representative currencies to test
as long as the mine disaster does not occur, the shortage will last for a long time. However, if there is a mine disaster, a large number of second-hand mine cards will directly enter the market. These cards are always running at full load and full speed, and their service life is greatly shortened compared with that of ordinary users. Even if the price is lower, they will roll over at any time, There is no need to start at all. Moreover, the second-hand market will be directly disrupted. At that time, it will be difficult for some normal users to get out of the second-hand market, and the deep-water fish's Dragon killing knife will explode the galaxy. Now it is said that NVIDIA is making some graphics cards without display output interface, which are provided to miners as mine cards. With a certain capacity, if the mine card still can't satisfy the miners, won't the miners buy the graphics card in the consumer market? The only function of these special mine cards is to prevent mine cards from flowing into the second-hand market, which can not alleviate the current shortage of graphics cards
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
