Miner's display card burned

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

< H2 > extended data:

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

The life of the graphics card is the same as that of the general electronic components, which is 6 to 10 years< br />
