Mine disaster machine router
Mining requires powerful computing power of computers. In the early days, it mainly relied on CPU, but now it mainly relies on mining machines integrated with a large number of graphics cards
the graphics card in the miner works continuously for 24 hours, and the heat dissipation environment is bad, so the long service life is shortened rapidly
the obsolete graphics card on the miner is the mine card. It is not recommended to choose this kind of graphics card, so it is very easy to have problems.
Mine card refers to the graphics card used by bitcoin mining machine, mostly amd graphics card
mine disaster refers to the decline in the price of bitcoin and the sale of second-hand mine cards
bitcoin mining machine graphics card long-term high load operation, graphics card service life will be reced accordingly, so the price will be cheaper
extended data:
bitcoin mining machine is a computer used to earn bitcoin. This kind of computer generally has professional mining chips, and mostly works in the way of burning graphics card, which consumes a lot of power. It is one of the ways to get bitcoin that users download software from personal computer and then run specific algorithm to get corresponding bitcoin after communicating with remote server
bitcoin mining started with low-cost hardware such as CPU or GPU, but with the popularity of bitcoin, the mining process has changed greatly. Nowadays, the mining activities are transferred to the field programmable gate array, and the hash speed can be achieved through optimization. The mining efficiency of this mode is very high
