Miner can only recognize 3 graphics cards

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

3. 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.

4. 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.

The miner is better

1. the electricity charge for mining with graphics card is very high, and the performance is not high, so it can't even earn the electricity charge

2. mining is an investment more than time and speed. We should try to dig more money in the shortest time. Therefore, the professional mining machines of BTC now stress the characteristics of simple operation, small footprint and low power consumption. For example, Yingtai has developed a professional mining motherboard with a computing power of 23.488g/hash, and the proct model is btc-24gh< br />

6. Mining machine
needs higher computing power, not the performance of graphics card. AMD and NVIDIA have the same price of graphics card, amd has higher computing power, so mining machine uses this kind of graphics card more, I hope it can help you

7. 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.

8. 1、 There is an oil indicator cover on the top of the instrial lock. Just screw it down and fill oil directly. Then there is an oil indicator window in front. The oil level should not exceed the second oil level line< (1) always refuel


all oil holes on the machine and all rotating parts should be refueled with clean sewing machine oil every 4 hours. Other oils and unclean sewing machine oil should not be used, so as not to affect the service life of the machine
(2) regular maintenance and inspection
it is necessary to keep the parts clean, regularly check whether the temperature and sound of the rotating parts are normal, and repair them immediately if any problems are found, so as to avoid damaging the machine
generally, minor overhaul is concted once a month, and cleaning and major overhaul are concted once a half year. After being put into use for a long time, it should be cleaned and overhauled first
the thickness and use speed of the sewing material should be selected within the specified range, and it should not be overloaded or over speed.

9. 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.
