Miner graphics card does not display
Specific steps:
< UL >first of all, we need to find a mine pool which is easy to operate and proces stable output. The role of the mine pool is to subdivide the data packets for each terminal. We can pay the corresponding amount of bitcoin according to the proportion of the data packets calculated by the terminal through the precise algorithm
-
the board can't recognize the graphics card, which may be e to insufficient power supply. You can check whether there is additional power supply on the board that is not fully connected
-
can update the BIOS of the motherboard to improve compatibility and better identify the graphics card
excessive overclocking
e to the use of components with higher technical parameters, some graphics cards have excellent overclocking capability, so many players advocate overclocking graphics cards to improve performance. However, there are both advantages and disadvantages. Overclocking can also lead to a significant increase in the heat of the chip. When it reaches a certain level, it will cause the problem of splash screen and crash. Even if not, it will also cause instability in some applications, such as games. Therefore, overclocking must be moderate. 4

More than 500W power supply
sapphire rx580 full load power to more than 200 watts, plus CPU and other hardware power consumption, need more than 500 watts of power supply
If the power supply is500, it is necessary to pay attention to whether it is rated power. The value of rated power is the rated voltage of the electrical appliance multiplied by the rated current. If the actual power of the graphics card is greater than the rated power, the electrical appliances may be damaged; If the actual power is less than the rated power, the graphics card can not operate normally
extended data:
the power of power supply can be divided into rated power, maximum power and peak power
rated power: the ambient temperature is between - 5 ~ 50 ℃, the input voltage is between 180V ~ 264v, and the power supply can stably output power for a long time
maximum power: at room temperature, when the input voltage is between 200V and 240V, the power supply can stably output power for a long time, and the maximum power is generally about 15% higher than the rated power. For example, the rated power of Xingu nuclear power 325pq is 250W, and the maximum power is 287w, which is close to 300W
peak power: the maximum power that the power supply can achieve in a very short time, and the time can only last between a few seconds and 30 seconds. The peak power is related to the operating environment and conditions, which is not a definite value, but the peak power can be very large, which is very easy to mislead users. For example, the rated power of Xingu nuclear power 325pq is 250W, and the peak power reaches 350W. Obviously, only the rated power and maximum power have practical significance
pay close attention to digging now. If it's too late, it will be devalued. Otherwise, even the electricity bill will not be enough.
bitcoin mining uses SHA-256 hash operation, which will carry out a large number of 32-bit integer cyclic right shift operations
interestingly, this kind of algorithm operation can be implemented by a single hardware instruction in AMD GPU, while it needs three hardware instructions to simulate in NVIDIA GPU. This alone brings an additional 1.7 times of computing efficiency advantage for AMD GPU.
