How to mine 12 cards
for mining machines, the most important thing is the graphics card. Generally, you can choose the most basic motherboard that supports 6 graphics cards, and later you can choose the more complex motherboard that supports more than 12 graphics cards. The specific suggestions are as follows:
1. CPU - CPU can choose the most basic and cheap CPU, as long as you can bring the system up normally, Generally, you can choose Intel's g3900 CPU with a unit price of about 200 yuan< Operating system is too laggy. If you use 6 graphics cards, you need at least 4G of memory. If you are 12 graphics cards, the windows operating system needs at least 8g of the memory. Otherwise, the system will be very stuck and then can not work normally. The Linux operation system can be 4G memory. < br > />2.
3. Motherboard - it is recommended for novices to directly choose the special mining motherboard of Yingtai series. The models are tb250 BTC with 6 card slots and tb250 btcpro with 12 card slots, as well as H81 series motherboard of Huaqing
4. Hard disk - SSD hard disk is needed for hard disk, because the reading speed is fast, and virtual memory needs to be set. SSD hard disk can improve some performance theoretically. If you use Windows system, you need at least 64GB, and Linux system can use 16GB
5. Operating system for windows, it is recommended that win10 system, corresponding to NVIDIA series and AMD Series graphics cards, can recognize up to 8 cards respectively. If the motherboard of 12 cards needs N cards and a cards to be mixed, then we can make full use of the motherboard graphics card slot
6. Graphics card - the mainstream mining graphics card models are amd Series graphics cards rx470, rx570, rx580, NVIDIA Series graphics cards gtx1060, gtx1070 and so on. It is recommended to choose 4G or more memory, and 8g is the best.
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
1: the price of the miner is higher
2: we need to consider how long it will take to get back the original
3: it's troublesome to buy and troublesome to maintain
4: it is time-consuming and power consuming, and it also needs to run the mining software with the computer on
5: there are risks of depreciation and damage
the above risks and defects make many miners shy away from buying mining machines. Fortunately, we are in the era of cloud computing. Now the era of "cloud
miner" has finally come. Now there are websites selling computing power on the Internet. That is to say, they have a large number of mining machine cluster equipment and sell their computing power on the Internet, Generally speaking, cloud mining machine mining has the following advantages:
1: there is no saying that "you can't get back the cost". How much you dig is how much you earn. If you don't want to dig, you can sell GHS computing power at any time
2: there is professional mining equipment space to ensure the uninterrupted operation of mining machinery
3: no freight, no electricity, no depreciation, no risk of damage
4: computing power can be bought and sold at will, not limited to 1g, or only 0.001g. If you want to buy more, you can buy more, and you can sell if you don't want to
5: "cloud miner" digs bitcoin on the server side. You don't need to turn on the computer, just wait to receive bitcoin
now there are fewer and fewer bitcoins that can be g, and it is more and more difficult. If you want to dig bitcoin, you have to start early
although you don't have a graphics card worth thousands of yuan and a miner worth tens of thousands of yuan, you can be a hardworking bitcoin miner because of the cloud miner! Get a lot of money. Now I will take you to operate the happy process of mining with the cloud mining machine, because at present, the interface of the cloud mining machine is mostly in English, which is difficult for some beginners to understand. I will explain each detail carefully with pictures and text, and translate it into Chinese, please rest assured.
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- O
