How many graphics cards can be used for miner at most

1.

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 />

2. The chance of mining is fleeting and worthless
as the price of bitcoin flies down, it has no value; But as an experiment, it can be tried, but the income is not enough for the electricity bill.

3. It depends on the power consumption superposition of the specific graphics card. The power supply is not always full output, but according to the demand. Now the 1080 single card is 180W, with six 100% running, it is 1080W, plus the power consumption superposition of other hardware. But I've only heard that the demand for password cracking machines is so high. I can't see such machines.

4. On the basis of motherboard, 6 cards can be mined by PCI-E X1 extension adapter
up to 7 cards can be mined by expansion card.

5. 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.

6. What is the risk of futures
it's not easy to answer this question. Many people just hear that futures are risky, and they shout that futures are risky. In fact, which investment has no risk
people think that futures are risky because futures are margin trading, You can use 100000 yuan to make a contract worth 1 million yuan. Your capital has been magnified 10 times. Then if the market goes in the opposite direction, your principal may be lost. For example, when you buy two hand 704 copper, the price is 55000 (one hand is 5 tons), and the required margin is only 55000 * 10 tons * 10% = 55000. If the copper falls to 50000, your loss is (55000-50000) * 10 = 50000 But I think the risk is completely controllable. Risk and return are relative. There is absolutely no investment with low risk and high return. Investment in an instry mainly depends on whether its game rules are fair. Futures are fair and open relative to the domestic stock market

7. The standard 6-truck miner has a certain cost performance ratio
the ordinary host you can match casually can't dig enough electricity.

That's the mainboard of the miner. It's for mining. It's not easy to make a computer. CPU is basically slag, many are integrated CPU. There are enough graphics cards now. The performance improvement of crossfire technology is limited. Even four of them have money to burn. The medium and high-end graphics cards fully meet various requirements. The picture below is a miner motherboard. CPU integrated. In addition to mining waste, a
