Why does the graphics card write forbidden for mining
mining, in fact, is a problem-solving process. First, we work out a formula with many answers, and then the dealer releases a random answer every other period of time. An answer is the prototype of a virtual coin. We can see who can calculate the answer at this time, and then this person or these people can divide the virtual coin. When the result comes out, we can find the answer, virtual currency is attached with information such as the computer information and problem-solving time of the tester, so that the virtual currency can be "materialized", that is, it has traceability and uniqueness attributes. At this time, the virtual currency is officially g out
using the graphics card is because the computing method of the graphics card is different from that of the CPU. The CPU focuses on logic computing. The graphics card is simple computing, and mining (that is, solving problems) just needs simple computing power. Therefore, mining with the graphics card
bitcoin miner is the equipment for mining bitcoin. The mining equipment can be ordinary computer or USB miner, It can also be a professional ASIC miner
It is true that ordinary computer CPU can mine bitcoin, but because bitcoin mining has formed a huge instry all over the world, it is difficult for indivials to mine bitcoin with ordinary computers. You need to buy expensive and professional bitcoin
ASIC mining machine
and join the bitcoin miners organization to dig bitcoin, that is, to join a mining pool for mining
First of all, CPU and GPU are designed differently for different missions in the computer:1. CPU is mainly optimized for serial instructions, while GPU is optimized for large-scale parallel computing
Modern multi-core CPUs aim at instruction set parallelism (ILP) and task parallelism (TLP), while GPUs aim at data parallelism (DLP)3. GPU often has a larger bandwidth of memory, that is, the so-called video memory, so it will also have good performance in high throughput applications
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 CPU is used to perform mining tasks. Because the CPU needs many transistors to execute various instructions, many transistors are idle in a cycle. The speed is slow and normal
In order to enhance the ability of displaying images, the graphics card saves many transistors which have nothing to do with the display function, so the graphics card can only display pictures, but it is much faster than the CPU in the task of displaying pictures. BTC needs to perform the same tasks as the graphics card, so the mining of the graphics card is faster than the CPU, So a card is more suitable for miningdoes not need too many instructions. In other words, the task of BTC only needs some specific transistors to be executed.

BTC needs to perform the same task as the graphics card, so the graphics card mining is faster than the CPU.
the same as the graphics card, The task execution mode of a card is closer to that of BTC than that of N card, so a card is more suitable for mining
the graphics card of mining is full load and continuously running 24 hours a day
so the mine card is a second-hand card, but the second-hand card is not necessarily a second-hand card, that is, "mine Nan". A large number of long-term mining a cards flow into the second-hand market, and the value of bitcoin plummets. It is generated through a large number of calculations according to a specific algorithm
AMD's consumer level graphics card is very good for procing bitcoin
this sentence has a warning effect on enterprise users (large-scale mining machine digs virtual token), manufacturers Sue enterprise users for better benefits, and indivial users Sue time-consuming and laborious, and the impact is not good. In addition, there is also a thick black interpretation that manufacturers printed this sentence in order to boost the momentum of mining and card speculation, so as to make their profits higher.
1: the working state of the mine card is 24 hours a day, full load and complex floating-point calculation, which does great harm to the original of the graphics card itself. The mine card mines for one day. Equivalent to about 10 days for ordinary users. So buy mine card is very easy to damage
2: as long as the graphics card is used in mining, the manufacturer will not guarantee it, or only guarantee it for half a year. Now, when you buy a graphics card, there is a label on its shell: "if the graphics card is used for mining, there is no warranty in case of problems".
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

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
