GPU not found in mining

1.

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 first step in setting up mining equipment is to choose the right hardware. This article will focus on GPU (graphics card) mining, of course, you can use CPU or ASIC equipment mining. Amd graphics card architecture is very beneficial to mining. NVIDIA card is not suitable for mining because of its low hash rate. The best NVIDIA graphics cards are less than 0.5 megahash. Notebook Hardware mining is not as good as NVIDIA card, which is a bad option for mining. You need to use a desktop system for mining. There is a desktop system to ensure adequate cooling of the hardware

the graphics card or card needs to be able to match the motherboard, and the power supply must have enough PCI-E connectors. Before determining the graphics card, pay attention to these. In order for the system to cool down sufficiently, you need to remove the cover of the chassis in order to get better heat dissipation. This is what people call "open air rig.". If you can aim the system at a fan or air conditioner, you can make the device cooler when it's running, thus extending its life and keeping it efficient

3. [usually, we should protect our computer and give some suggestions]
1. It is necessary to install anti-virus software, update the virus library in time, install firewall (anti Trojan horse, hacker attack, etc.), kill virus regularly, and maintain the security of computer operation
it is recommended that the owner of the building can install Tencent computer manager, which is a free professional security software with two in one anti-virus Management (only need to download one ), small memory, good anti-virus, good protection, and no false alarm and killing. It has a world-class anti-virus software embedded anti-virus engine, such as cloud killing engine, anti-virus engine, Jinshan cloud killing engine, Avira killing engine, xiaohongsan and killing repair engine
software upgrade, vulnerability repair and garbage cleaning are automatically and regularly set, which is necessary for lazy people
2; Open Tencent computer manager toolbox vulnerability repair
3. Don't go to some unknown websites or download things casually
4. You should also be on guard against portable storage devices (such as USB flash disk, where viruses are rampant recently)
5. Don't go to unknown websites or receive strange e-mails. After downloading the compressed package file, scan the virus first
6. Close unnecessary ports
7. If you have time and energy, learn some common computer skills and knowledge

finally, I would like to say that if you are very careful but still poisoned, you can't help it It's a good choice to backup the system with ghost.)

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 is

500, 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

5. Smart home is a terminal of Internet of things, and the effective connection between each terminal needs the technical support of cloud service and IPv6. The establishment of smart home standard is inseparable from them
the establishment of an instry standard also needs the following two conditions:
first, practical, efficient and feasible technical standards: the graal establishment of cloud services, Internet of things and IPv6, which makes the technical standards clear, but also has a lot of uncertainty
Second, enough instry influence: at this stage, most of the smart home solutions and procts manufacturers still stay in the physical control layer, and no one has enough instry influence
so now there is no standard for smart home, but the emergence of this standard will be inevitable
at this stage, ZigBee and Z-Wave are the two most representative technical standards for smart home control system standards. ZigBee protocol starts from the architecture of Internet of things, and Z-Wave is specially customized for smart home. However, the enterprises using these standards are still in the early stage of development e to the limitations of peripheral facilities, cost and technical perfection. Throughout the market, smart home procts are still in the primary stage of physical control, and there is no obvious connection between informatization, cloud services and Internet of things
the development of domestic smart home system is also very rapid in recent years, almost following the pace of international development. Haier and others in the early stage also have great changes after the first round of shuffling. Now the domestic smart home technology is dominated by rf315, 433 radio frequency 2262.1527 standard protocol, which has low threshold and low development cost, In the early stage of the development of the market has played a very good role in promoting, and with the maturity of the market, the defects of technology graally exposed, those who did not make technological transformation of the company are dismal
after the first round of reshuffle, some new technologies have emerged, with 2.4G and 433 carriers as the most representative. In terms of protocol composition, ZigBee networking technology has great advantages in terms of cost, and adheres to the development of cloud service architecture. Voice control function makes the control from physical control to content control, It has achieved effective integration with Internet of things and cloud services
in terms of market promotion, the OEM scheme is adopted to accelerate the market share of smart home. From these two points, it is not difficult to see that Shenfu smart company is also going to the standard. Through market feedback, the integrity of the agreement can be continuously improved, and the development risk of other smart home brands can be reced by means of technology, so as to obtain the market share. The direction is right, The method is good, but I don't know how far I can go
although there is no standard for smart home for the time being, with the graal maturity of the market, after several rounds of market adjustment and reshuffle, the technology used by the companies standing in the market will be the standard. The author thinks that the market standard can never be discussed by a group of experts, and it must be eliminated through the baptism of the market. I hope that in the future, the establishment of international standards will be the basis for the development of smart home, We can see the figure of Chinese enterprises

6. This depends on your existing equipment, and what effect you want to achieve. Is it a personal enterprise application or a project declared by the government!

7. Have you set up a graphics card in this mine? The user name and password filled in here are from the device
it is not the account password of the mining area.

8. Generally, amd graphics card has many stream processors and fast mining. In those years, 68707850280 (without x) was popular. Now the new card is worth more than 470d in mining. It's worth 470 yuan. The cost performance ratio and efficiency ratio are outstanding.

9. Bitcoin was obtained by CPU in the early days. With the continuous development of GPU speed and the emerging advantages of GPU general computing, miners graally began to use GPU instead of CPU for mining
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.
