A card machine course
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
you need to buy multiple PCI e motherboards, one motherboard needs 6 cards, the power supply needs to be rated above 1000W, the CPU has enough al cores, the memory is 4G, and the graphics card needs gtx1060 or AMD rx470 / 570 or above a card
just download the mining software to start
however, if you calculate the cost, one card needs 3000, six cards need 18000 or more, at least 500 power supplies, CPU 300, memory 300, motherboard and PCI extension cable need about 800, and one monitor. In this way, a simple mining machine will cost more than 20000, and the average power consumption of a graphics card is 200W (n card level, a card 250W). Six of them are 1200W. The whole machine has this power. One hour is 1.2 kwh, and one day is full load. The electricity charge of 16x1.2x0.6 + 8x1.2x0.3 = at least 17.85. Although using a card is more efficient, it costs more electricity
a miner can earn 100-200 yuan a day. How long will it take to recover the cost? Can the value of money still be at this level at that time?

may be caused by the driver is not completely installed, or the driver version installed does not match the system
-
re install other driver versions, or ask the customer service of the graphics card brand if they need to install the driver for mining and switching< br />
