GPU mining burning graphics card
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
It will accelerate the aging of graphics card
in order to make money, the graphics card works continuously for 7x24 hours and runs at full load. Some people will overclock the graphics card in order to earn more money. The general home game graphics card is not designed for this kind of use environment at all. Long time full load operation will lead to accelerated aging of the graphics card, Generally, the life of the graphics card used for half a year of mining is longer than that of the normal use of the players for three years, so now the major brands have made strict restrictions on the quality assurance of the cards

principles of computer Mining:
starting from the essence of bitcoin, the essence of bitcoin is actually the special solution generated by a bunch of complex algorithms. A special solution is one of the finite solutions of a system of equations. Every particular solution can solve the equation and is unique. In the metaphor of banknotes, bitcoin is the number of the top word of a banknote. If you know the number of the top word of a banknote, you will have the banknote
and the process of mining is to constantly seek the special solutions of the equations through huge amount of calculation. The equations are designed to have only 21 million special solutions, so the upper limit of bitcoin is 21 million
to mine bitcoin, you can download the special bitcoin computing tools, register various cooperation websites, fill the registered user name and password into the computing program, and then click the operation to officially start. After completing the installation of bitcoin client, you can directly obtain a bitcoin address. When others pay, you only need to paste the address to others, and you can pay through the same client
after installing the bitcoin client, it will assign a private key and a public key. You need to back up the wallet data containing your private key to ensure that your property is not lost. Unfortunately, if the hard disk is completely formatted, personal bitcoin will be completely lost
there are many stream processors in GPU of graphics card. For example, the old HD5770 has 800 stream processors, which is equivalent to 800 computing cores. In recent years, the mainstream high-end graphics card has more built-in stream processors and more powerful computing performance. Using GPU for mining operation, the stream processor is used for parallel operation, and the mining program also optimizes the GPU parallel operation, so the operation efficiency is particularly high, and the efficiency of bitcoin mining has been greatly improved
the number of CPU cores is relatively small. At present, the number of the most powerful mainstream desktop processor cores is no more than 10 or 20 (many are logic cores virtualized by hyper threading technology), and the parallel computing power is far less than that of GPU.
overview
graphics card, also known as video card, is an important part of the computer. It undertakes the task of outputting display graphics. For people who like to play games and engage in professional graphic design, graphics card is very important. The display chips of mainstream graphics cards are mainly made by NVIDIA (NVIDIA) and AMD (ultra micro semiconctor). Generally, the graphics cards with NVIDIA display chips are called N cards, while the graphics cards with AMD display chips are called a cards[ 1]
computers with high configuration all contain graphics card computing core. In scientific computing, graphics card is called display accelerator[ 1]
Video chipset is the main processing unit of graphics card, so it is also called graphic processing unit (GPU). GPU is the first concept put forward by NVIDIA company when it released geforce 256 graphics processing chip. Especially when dealing with 3D graphics, GPU makes the graphics card less dependent on CPU, and completes part of the work originally belonging to CPU. The core technologies of GPU include hardware T & L (geometry conversion and illumination processing), cubic environment material mapping and vertex blending, texture compression and bump mapping, al texture four pixel 256 bit rendering engine, etc[ 1]
all kinds of 3D special effects supported by the graphics card are determined by the performance of the display chip, and what kind of display chip is used roughly determines the grade and basic performance of the graphics card, such as NVIDIA GT series and AMD HD series[ 1]
there are many ways to measure the quality of a graphics card. In addition to using test software to test and compare, there are many indicators for users to compare the performance of a graphics card. The main factors that affect the performance of a graphics card are the frequency of the graphics card, display memory and other performance indicators [1].
Jiulong jade has four unique characteristics:
first, it has unique connotation of dragon jade. Jiulong, dinosaur, Jasper, jade, nephrite, jadeite in one. Hence the name "Jiulong Jasper" is worthy of the name, loud and beautiful. It is the best national stone suitable for the belief of dragon jade culture in China
Second, it has huge, extra large, super large jade, rare stone resources, and its great advantage in block size. It is suitable for the huge demand of China's long-term development
thirdly, there are four types of jade of the existing dragon; There are also five types of jade. It covers many types of famous jade and stone in Chinese history. The existing original jade and its marble landscape painting; Pu jade and its hermit type; Ziyu and its shape stone and Longwen stone type; There are also Ziyu and Yuhua stone types, and Qinse jade and its strange stone types. Therefore, there are many types of dragon jade culture. The world is unique, very rare< 4. There are four types of natural jades of the same kind and heterogeneity in the history. There are also four famous jade in the history of the five elements in China. Therefore, the jade of Jiulong in Southeast China contains the later enlightenment of Chinese five element jade.
Check whether the graphics card is mine card or not, you can refer to the following three points:
1, st
when the graphics card is running, it needs heat dissipation, the heat dissipation is mainly the fan on the graphics card, so the st on the fan will give us some judgment. Generally speaking, the self used video card and fan will not always run at full speed. The cotton gauze of all kinds of textiles in the room is scattered, so the st on the fan is often mixed with cotton wadding
extended data:
the maintenance of the graphics card is as follows:
1. The chassis is well ventilated, which can protect the graphics card and all the hardware in the machine, and prevent the high temperature from causing the running speed to drop, crash or even burn. The machine room is hot. In summer, you can take down the side panel of the chassis to help heat dissipation, or add a fan to help heat dissipation. If conditions permit, it is recommended to use water cooling to improve the working efficiency of the graphics card
2. The interface of the graphics card and the display are connected correctly on the street, and the virtual connection is easy to be interrupted frequently or ignited, which will cause the interface of the graphics card to burn down.
3. The effect of overclocking on the graphics card is not very obvious. On the contrary, it is easy to cause a huge increase in heat and slow down or even burn down of GPU
4. Dust cleaning, no matter the Chaka or motherboard or other components, will inevitably proce st after a long time. It is necessary to remove the chassis and carry out st removal work to ensure the normal work of each component

1. Price
you may know that intensive mining is quite expensive because it requires a lot of resources. The power consumption is huge, and with everyone's participation, the difficulty of mining will increase, which means that a lot of computing power is needed
as the cost increases, you should remember that the price of GPU for mining should be one of your top considerations
nowadays, most mining equipment is created with several GPUs, so that they can make more (Network) contributions and make more money (tokens). The cost of each GPU may vary, depending on how much you are willing and able to spend, but you can expect the price of each GPU to range from $150 to $1300
your best choice is to buy those graphics cards with moderate price. In this way, you won't pay too much, but you can still get a decent proct, and it's worth your time to mine
2. Power consumption
as mentioned above, power consumption is a big problem. The greater the power consumption, the greater the heat generated in the mining process. But these two problems can be controlled as long as high wattage GPU is not used
if you don't want to deal with these problems, choose a low or medium wattage GPU, or pay extra for advanced cooling technology. However, you should remember that this will mean that your hash rate will be reced, so your profit will not be so high
3. Hash rate
when we discuss hash rate, it is also an important factor, which is determined by the execution speed of GPU, or mining speed. The type of GPU you use and the algorithm your token uses are also important factors
therefore, if you do not have a specific currency, perhaps the best thing is to buy a GPU with a comprehensive hash rate, so that it can play a role in a wider range of hash algorithms
in this way, you don't have to dig one coin, but have the opportunity to dig another
4. Warranty is also something you should pay attention to. However, it should be noted that mining will not damage your GPU more than games or other high-performance tasks
however, as long as you choose to mine, your GPU must perform under continuous load, so for the sake of safety, it is recommended to buy a 2-year warranty. After all, if something happens, the money will be wasted
5. Overclocking performance
overclocking is also something you need to study, because many GPUs can adjust to faster performance, sometimes even 20-30% faster
this can make the graphics card more efficient, help you make more contributions when solving each block, and then ensure more sharing. Considering this, it depends on the overclocking performance of GPU. When it is forced to the limit, it is necessary to choose the one that can do better
of course, there are other minor factors that can also affect your performance as a miner, but these are the main things to pay attention to.
