Mining to reduce core cost
1: material purchase
1.1: motherboard suggestion: the graphics card mining does not need a lot of PCI e bandwidth, and the motherboard with PCI-E 1x can meet the bandwidth requirements. Generally, the motherboard has 3-5 PCI-E 1x interfaces and 1 PCI-E 16x interface. In addition, the motherboard has a large 4Pin power supply interface, which improves the stability to a certain extent. PCI-E 1x needs to purchase the extension cable from 1x to 16x
1.2: recommended models: 280x, 290380x, 390470d, 470480, 4G and above; N card GTX 950106010701080 and above. A card is recommended for eth / etc mining, while n card is inefficient; Zcash mining a card and N card can be, n card has a slight advantage in speed, mainly low power consumption.
mining refers to the use of bitcoin mining machine to obtain bitcoin, that is, the computer used to earn bitcoin. If you can get bitcoin, you can make money this kind of computer generally has professional mining chips and works by installing a large number of graphics cards, which consumes a lot of power. The computer downloads the mining software and then runs a specific algorithm to get the corresponding bitcoin after communicating with the remote server
precautions:
1. It's better to use DIY mining machine, from purchasing accessories to assembly, and then to mining software, to learn, focus, practice and graally understand the blockchain
Mining is actually a fixed investment process: regardless of the currency price, a certain amount of positions will be increased every day3. The bitcoin wallet used to store bitcoin uses military level encryption, which makes it impossible for hackers to steal easily. Bitcoin wallet also allows users to set two passwords, a public account password and a private password. The user of public account password is to let the user receive bitcoin. If users want to withdraw or transfer bitcoin from their accounts, they need to use a private password
there are many stream processors in GPU of graphics card. For example, the old HD5770 has 800 stream processors, which is equivalent to 800 computing cores. In recent years, the mainstream high-end graphics card has more built-in stream processors and more powerful computing performance. Using GPU for mining operation, the stream processor is used for parallel operation, and the mining program also optimizes the GPU parallel operation, so the operation efficiency is particularly high, and the efficiency of bitcoin mining has been greatly improved
the number of CPU cores is relatively small. At present, the number of the most powerful mainstream desktop processor cores is no more than 10 or 20 (many are logic cores virtualized by hyper threading technology), and the parallel computing power is far less than that of GPU.
