The miner's eight graphics cards show only seven

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

2. Your motherboard to support four graphics cards, generally can only support three
in addition, if your hard disk is m.2 SSD or U2 interface, inserting the fourth graphics card may occupy the hard disk's PCI bus, resulting in hard disk unreadable.

3. 1. To detect whether the power supply is fully connected and whether the power consumption is enough, it needs to be used with brand power supply with high power consumption and good quality
2. For the specific model of the motherboard, it is recommended that you consult the manufacturer's technology, and under the guidance of customers, you may need to brush the latest BIOS file.

4. 1. Because the bandwidth of the first x16 independent graphics card slot is provided by the CPU, while the second one is generally provided by the chipset (the highest X4 provided by the chipset); 2. Some of the bandwidth of the first x16 independent graphics card slot can be split (generally divided into X8 + x8), so that the bandwidth of the second graphics card slot is only X8. In fact, if two graphics cards are inserted at the same time, the bandwidth of the first graphics card slot is only X8 at this time; 3. Some chipsets or CPUs can provide bandwidth. At this time, the speed of the second, third... Graphics card slots may also be x16, depending on different chipsets; 4. Generally, only high-end and flagship chipset motherboards are allowed to split the PCI-E channel of CPU (such as Z170, x99, etc.). 5. If it's not a high-end chipset, the bandwidth of the second graphics card slot is at most X4

5. The power on time is too long. It is estimated that the contact is poor. Remove it, rub the golden finger of the graphics card with the eraser, and then test it one by one. No problem. It's all plugged in.

6. First of all, let's see what qualifications he has. Then let's see where the regulatory agency is. The formal platform has qualifications and the regulatory agency has the freedom of access to funds

7. The driver is not installed properly. Another 580 is asus's best

8. Power supply is insufficient or PCI-E does not work, it is recommended to dig
pay close attention to digging now. If it's too late, it will be devalued. Otherwise, even the electricity bill will not be enough.

9. There are short slots and long slots. The long slots are for graphics cards, and the short slots are for PCI cards, network cards, sound cards, etc

10.

The premise is that the motherboard needs to support eight graphics cards to mine bitcoin
