"Graphics card mining" is actually using graphics cards to dig bitcoin, so that graphics cards can work under high load, and those that are eliminated become mining cards. Generally, the core pc board on the back of mine card is seriously discolored.

For mining machines, the most important thing is the graphics card. Generally, you can choose the most basic motherboard that supports 6 graphics cards for entry mining, and you can choose a more complex motherboard that supports 12 graphics cards later. Specific suggestions are as follows:

1, cpu——cpu can choose the most basic and cheapest cpu, as long as it can be brought to the system normally. Generally, you can choose intel's G3900 cpu, and the unit price is around 200 yuan.

2, memory-with 6 graphics cards, at least 4g memory is needed. If it is a 12 graphics card, the windows operating system needs at least 8g of memory, otherwise the system will get stuck and then it will not work normally. If it is a linux operating system, it can have 4g memory.

3. Motherboard-Motherboard: Novices are advised to choose Yingtai series special mine motherboards directly. The models are 6-slot tb250-btc and 12-slot tb250-btcpro, and Huaqing h8 1 series motherboards can also be selected.

4, hard disk-hard disk needs ssd hard disk, because of the fast reading speed and the need to set up virtual memory, ssd hard disk can theoretically improve some performance. If you use windows system, you need at least 64gb, and if you use linux system, it can be 16gb.

5. Operating system-for-Windows, win 10 system is recommended, which can identify up to 8 cards of nvidia series and amd series graphics cards respectively. If the motherboard of 12 card needs to mix N cards and A cards, you can make full use of the motherboard graphics card slot.

6. Graphics card-The mainstream mining graphics card models include AMD series graphics cards RX470, RX570, RX580, Nvidia series graphics cards GTX 1060, GTX 1070, etc. It is recommended to select more than 4G memory, and 8G is the best.
