12 graphics card miner course

1.

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

2. Mining now? Your 12 graphics card mining machine is basically impossible to make money, it's better to buy a fund to speculate in stocks

3. It is recommended to use 360 driver master software to install driver. It can intelligently detect hardware and match the most suitable driver for installation

4. The CD-ROM is the most suitable driver for this computer. The steps to update the driver are: start → control panel → system → hardware → device manager → click Scan to detect hardware changes on the top of the toolbar. If there is a yellow warning sign in the driver bar, it means that the driver is not installed correctly. At this time, the driver needs to be updated. At this time, you need to right-click the wrong driver → update driver → insert the drive disc to update automatically.

5. If you are a novice, I don't recommend taking this, because the risk is very big. And the efficiency of self-employed is very low
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?

Mini excavators with the weight of less than 6 tons, small excavators with the weight of 6-15 tons, medium excavators with the weight of 15-30 tons, large excavators with the weight of 30-150 tons, and super large excavators with the weight of more than 150 tons. Sany Heavy Instry has more than 200 tons of super large hydraulic excavator

the three most important parameters of excavator are operating weight (mass), engine power and bucket capacity. Common excavator structures include power device, working device, slewing mechanism, control mechanism, transmission mechanism, walking mechanism and auxiliary facilities. The transmission mechanism transmits the power of the engine to the hydraulic motor, hydraulic cylinder and other executive elements through the hydraulic pump, and promotes the action of the working device, so as to complete various operations

the materials excavated by excavators are mainly soil, coal, silt and soil and rock after pre loosening. From the development of construction machinery in recent years, the development of excavator is relatively fast, excavator has become one of the most important construction machinery in engineering construction

extended data

there are two common excavator driving modes: internal combustion engine driven excavator and electric drive excavator. Among them, electric excavator is mainly used in plateau hypoxia and underground mine and some other flammable and explosive places

according to the different scale, excavators can be divided into large excavators, medium excavators and small excavators

according to the different walking modes, excavators can be divided into Crawler excavators and wheel excavators

According to different transmission modes, excavators can be divided into hydraulic excavators and mechanical excavators. Mechanical excavators are mainly used in some large mines

According to the use, excavators can be divided into general excavators, mining excavators, marine excavators, special excavators and other different categories

According to the bucket, excavators can be divided into forward excavator, backhoe excavator, dragline excavator and grab excavator. The front shovel excavator is mostly used to excavate the materials above the surface, and the backhoe excavator is mostly used to excavate the materials below the surface
