Dual graphics card motherboard

1. Now it's too late to dig. It's three months earlier. Now it's possible that there will be a mine disaster at any time. Moreover, the computer hardware needed for mining is extremely noisy, and it's not worth it. To dig, the computer is to choose six graphics card interface motherboard, the best is to match six AMD rx570 or rx580 single display
NVIDIA's best performance price ratio graphics card is gtx1060 6G.

2.

as a middle-aged miner for 13 years, let's talk about the feeling of mining before.

I bought four mining machines in the past. bitcoin uses CPU and I'm not familiar with it, so I use the form of buying graphics card to dig Wright's coin.

the first one is a simple double card mining machine, not a mining machine strictly speaking, but a double 7950 machine, At that time, I thought about digging for a while. If I didn't make money, I could still play games by myself. As a result, I found that the efficiency was really not high. Later, I used to dig some dog money and play with it.

the second one was the popular 6-card miner in those years. At that time, there was a powerful motherboard, which could run for 6 yuan by connecting with the PCI adapter and changing the BIOS. At that time, I could dig a lot of Wright's money every day with this machine, It's a pity that there are too many people digging, so it took more than 80 days to dig the coins. The third and the fourth are professional mining machines. At that time, the new chips were used to mass proce mining machines. Although they were expensive, the power consumption decreased a lot. It took about a year to dig, In the end, he retired, g up other counterfeit coins for a while, and then sold them.

generally speaking, many websites have no credibility at all in the past few days. They actually know what the concept of excessive increase in computing power is after digging up the money.

when ZF suppressed it, the assets immediately shrank by nearly 70%, but they still didn't sell because of their faith, On the contrary, after selling the miner, I bought some coins and put them in my hand. When I bought 100, I g them and only bought 15. Hey, the miner was sealed and put under the bed. After waiting for three years, I found that it rose again. This year, when bitcoin rose to 2W, I sold some Leyte coins and paid the down payment. Almost 300 of them were sold. Now it seems that the highest is 380, Ha ha

now I still have some money in my hand, and I plan to hold it for a long time, but I won't dig any more. However, I still have a lot of orders with our first-class suppliers. In the past two months, I sold nearly 150 cards, and the more I sold, the more I sold. Some cards are about to double, which is even crazier than that in 2013, The existence of e-money has its own value in the end, but it does not deny that there are so many speculators who come in to fight. There are indeed those who pursue the price. After the boom, there will be a wave of leeks cutting. In the final analysis, bitcoin is just an investment. Everyone feels different about the risk. The strength of big funds is still strong, and it is inevitable for retail investors to be cut, But it's better than A-share at least.

mining is not a good thing. The big miners are in the remote areas with low electricity charges, many mining machines and low cost. Most people dig at home, and that's just a little fuss.

finally, it's not a good thing to grow too fast. Those who are confident can come in and show their operation. If they don't have much ability, don't come in, Only by routine

3. The current difficulty is about 0.16 LTC per M computing power per day.

4. The graphics card can be opened up to 4 channels at most. No matter how many PCI links are not supported, it must be on a professional server board. The system bus has a total of x16, which can be divided into X8 + X8 or X4 + X4 + X4 + x4, and can not be removed

5. In the task of mining, the graphics card uses the general computing function of GPU, and the graphics memory of the graphics card itself is enough for it. 4GB of memory on the motherboard is OK, and there is no need to consider the single and al channel memory problem.

6. 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.

7.

With the deepening of the interaction between the subject and the object, the continuous balance of cognitive function and the continuous improvement of cognitive structure, the indivial can be released from the egocentric state, which Piaget called decentralization

This kind of open, flat and equal system phenomenon or structure is called decentralization

8. It's too difficult for you to ask this question, because the difficulty of mining is changing at any time. I can only tell you how much bitcoin you can dig with your current computing power. Avalon2 single-mode set (chip frequency 1500mh / s) 100g can dig 0.0048 BTC, avalon3 machine 40 days back The chip frequency (450mh / s) is 800g, and it can dig up to 0.0385 BTC, but the recovery time is relatively long
mining machinery is a high-risk instry. If you have abundant funds, it is recommended that you set up a large-scale mine for mining. If you are a retail investor, it is recommended that you dig carefully.

9. 1、 How to use people  People who have been to the temple know that when they enter the temple gate, first of all, Mitha Buddha greets visitors with a smiling face. To the north of him, there is the black mouthed and black faced Wei Tuo. But it is said that long ago, they were not in the same temple, but in charge of different temples.  He was enthusiastic and happy, so many people came, but he didn't care about anything. He didn't manage his accounts well, so he still couldn't make ends meet. Although Wei Tuo was a good accountant, he was too serious and overcast all day, which made fewer and fewer people. Finally, the incense was cut off.  Buddha found this problem when he was checking incense, so he put them both in the same temple, and mile Buddha was in charge of public relations and welcomed guests from all over the world, so incense flourished. Weituo was selfless and meticulous, so he was in charge of Finance and strictly controlled. In the division of labor and cooperation between the two, the temple is thriving.  In fact, in the eyes of the masters, there are no useless people. Just like a martial arts master, he doesn't need precious swords to hurt people by picking flowers and flying leaves. The key is how to use them.  2、 Parrot  A man went to buy a parrot and saw the front sign of a parrot: the parrot can speak two languages and the price is 200 yuan.  Another Parrot said: "this parrot knows four languages and costs 400 yuan.". Which one should I buy? Both of them are very cute and flexible. This man can't make up his mind&  Results suddenly found an old teeth of the parrot, coat color dim scattered, price 800 yuan.  The man quickly called the boss: does the parrot speak eight languages? The owner said: No. The man was surprised: then why is it that old, ugly, and incompetent are worth the number? The owner replied: because the other two parrots call this parrot boss.  This story tells us that real leaders don't necessarily have their own abilities. As long as they know how to trust, delegate power and cherish, they can unite stronger forces than themselves, so as to improve their own value. On the contrary, many people with very strong abilities are too perfectionist, so they have to do things by themselves, and no one is better than themselves. In the end, they can only be the best key tackling personnel and sales representatives, You can't be a good leader.  3、 Kangaroo and cage  One day, the zookeeper found that the kangaroo had run out of the cage, so he held a meeting to discuss it and agreed that the height of the cage was too low. So they decided to increase the height of the cage from 10 meters to 20 meters. The next day they found that the kangaroo still ran outside, so they decided to increase the height to 30 meters.  I didn't expect to see all the kangaroos running outside the next day, so the administrators were so nervous that they decided to raise the cage to 100 meters. One day giraffes and kangaroos were chatting, "do you think these people will continue to raise your cage?" Asked the giraffe“ It's hard to say "If they keep forgetting to close the door," said the kangaroo  Management experience: there are "the beginning and the end", "the importance" and "the priority". Closing the door is the beginning, raising the cage is the end, abandoning the beginning and chasing the end, of course, there is no point. What is management? Management is to first analyze the main and secondary contradictions of things, recognize the "essence", "importance" and "priority" of things, and then start from the important aspects.  4、 Bianque's medical skills  King Wen of Wei asked the famous doctor Bian que, "your three brothers are all good at medicine. Which one is the best?" Bian que replied: "elder brother is the best, middle brother is the second, and I am the worst." King Wen asked again, "then why are you most famous?" Bian que replied: "elder brother's treatment is before the onset of the disease. Because most people don't know that he can eradicate the disease in advance, his fame can't be spread; Brother Zhong's treatment is at the beginning of his illness. Most people think that he can only cure minor diseases, so his fame only reaches his hometown. And I treat it when it's serious. Most people have seen me perform major operations such as bloodletting through needles on meridians and dressing medicine on skin, so they think that my medical skills are excellent and my fame is resounding all over the country. "  Management experience: control after the event is not as good as control in the event, and control in the event is not as good as control in advance. Unfortunately, most business operators fail to realize this point, and only seek to make up for the heavy losses caused by wrong decisions. And often even if the famous "airborne soldiers" are invited, the result will not help.  5、 Qu Tu's salary  A guest came to someone's home and saw that the chimney on the host's stove was straight, and there was a lot of wood beside it. The guest told the host that the chimney had to be changed, and the wood had to be removed. Otherwise, there might be a fire in the future. The host did not make any watch. Soon the host's house was on fire, and his neighbors rushed to put out the fire. Finally, the fire was put out. So the host cooked sheep and slaughtered cattle, and entertained the neighbors for their contribution to the fire fighting, The chimney Turner. Someone said to the host, "if I had listened to that gentleman's words, I would not have prepared a banquet today, and there was no loss from the fire. Now I would like to reward you on merit. The person who originally gave you advice was not appreciated, but the person who put out the fire was a guest. It's really strange." The host immediately realized that he was going to invite the guest who had given advice to have a drink.  Management experience: it is generally believed that the person who is able to smooth out or solve all kinds of thorny problems in the process of enterprise operation is an excellent manager. In fact, this is open to question. As the saying goes, "prevention is more important than treatment", which can prevent problems before they happen, and is better than solving them after they have become. From this point of view, the preventer of enterprise problems is actually better than the solver of enterprise problems.  6、 Saving lives  In a fierce battle, the captain suddenly found an enemy plane diving down to the position. As a rule, you should not hesitate to lie down when you find an enemy plane diving. But the captain did not lie down immediately. He found a little soldier standing four or five meters away. He didn't care to think much, a fish leaped and flew to press the little soldier tightly under his body. At this time, there was a loud noise, and the splashing soil fell on them one after another. The captain patted the st on his body. Looking back, he was shocked: his position just now was blown into a big hole.  7、 Go out  In ancient times, there were two brothers each carrying a suitcase to travel far away. Along the way, heavy luggage will be the brothers are out of breath. They had to change their right hand when their left hand was tired, and they changed their left hand when their right hand was tired. Suddenly, big brother stopped, bought a shoulder pole on the side of the road, and hung two suitcases on the shoulder pole. He picked up two boxes and set out on the road. On the contrary, he felt much more relaxed.  It may be far fetched to connect the two stories, but they do have amazing similarities: the little soldier and the little brother in the story are lucky, but the captain and the big brother in the story are even more lucky, because they help others as well as themselves!  Management experience: on the road of our life, we will certainly encounter many difficulties. But do we all know that on the way forward, removing the stumbling blocks at the feet of others is sometimes just paving the way for ourselves?  8、 Son of fish King  There is a fisherman who has first-class fishing technology and is honored as the "king of fishing". However, when Yu Wang was old, he was very distressed because his three sons had mediocre fishing skills. So he often told people his distress: "I really don't understand why my sons are so poor when my fishing skills are so good? I've taught them fishing techniques since they were sensible. I've taught them the most basic things. I've told them how to catch fish easily by weaving nets, how to row boats without disturbing them, and how to get fish into the urn easily. When they grow up, I teach them how to recognize tides and fish floods... I have imparted to them all the experiences I have worked hard for many years, but their fishing techniques are not as good as those of the fishermen's sons who are inferior to me! " After listening to his story, a passer-by asked, "have you been teaching them hand in hand?"“ Yes, in order to let them get first-class fishing technology, I teach them very carefully and patiently“ Do they follow you all the time? "“ Yes, in order to let them avoid detours, I always let them follow me. " The passer-by said, "in this way, your mistake is obvious. You only teach them skills, but you don't teach them lessons. For talent, no lessons and no experience can make a person a great weapon!  9、 Apples by the river  An old monk, surrounded by a group of devout disciples. On this day, he told his disciples to go to Nanshan and get a load of firewood. The disciples hurried to the river not far from the mountain, and everyone was stunned. I saw the flood rushing down from the mountain, so I couldn't cross the river to collect firewood in any case. The disciples were a little dejected when they came back without success. Only a little monk and his master were at ease. The master asked why. The little monk took an apple out of his arms and handed it to the master. He said that he couldn't cross the river or get firewood. Seeing an apple tree by the river, I picked the only apple on the tree. Later, the little monk became a descendant of the master.  There are endless roads and rivers in the world. It's also a kind of wisdom to turn around when you can't cross the river. But the real wisdom has to do one thing by the river: fly the kite of thought and pick an "apple". People who look at the past and the present and hold such a belief in life have finally realized the breakthrough and Transcendence of life.  10、 The right hand holds the left  There is a popular doggerel on the table: holding my wife's hand is like holding my left hand with my right hand. Whenever someone reads: familiar or unfamiliar with a table, people will laugh, the atmosphere immediately relaxed. Of course, this is based on people's consistent understanding of the doggerel - feel accurate, describe in place. One day at the dinner table, someone read the doggerel again, and the men laughed as usual. It turned out that one of the women at the table didn't smile. Don't take it seriously when men are busy talking and joking. I didn't expect the woman to say seriously: the best thing is that "the right hand holds the left hand.". First, the left hand can be trusted by the right hand most; Second, the left hand and the right hand belong to each other; Third, any other hand can make you happy and excited, and you can shake your hand after that. Only your left hand can shake you off and you will be incomplete, right? A table of men admire, praise women's deep and unique understanding, the woman said faintly: what deep and unique, might as well go back to read to your respective wives, see what they say. Some of the brave men went back to test their wives. Sure enough, their understanding was the same as that of the ladies at the dinner table. They're all left-handed, and men are left-handed, of course. And they are all right-handed. Of course they think right-handed.  11、 Decision making  A farmer rescued his wife from the flood, but his child was drowned. After the event, there was a lot of discussion. Some said that he was right, because the child could have another child, but the wife could not be raised from the dead. Some said that he had made a mistake because his wife could marry another, but his child could not be raised from the dead. After listening to people's comments, I was also puzzled
