How many graphics cards can mine
are you still thinking about mining these days? This is not the year of 2010. Now, don't think about making money from small-scale mining, unless you have a multi million investment. Now, it's large-scale mining with mining machines, and professional management of the whole computer room. Now, there are several ways for personal investment. 1. Buy BTC by yourself. 2. Futures trading. 3. See ipo4. It's hard to get back the capital even if you buy butterfly mining machines by yourself. According to the current price and difficulty of mining machines, mining machines are generally expensive It takes three months to get back the capital (not including electricity, but only mining machine money). But don't forget that the difficulty has been increasing, so you can't get back the capital in your personal mining life. A better way is to buy the power stock through IPO. If you don't say that, you can talk to me about mining teaching as follows http://cnbtcnews.com/bitcoin-study/what-is-bitcoin/bitcoin-from-beginner-to-master.html
21.5 * 3600 seconds * 24 hours = 1857600 M / day
1857600 / 1024 / 1024 = 1.7715 T / day
a t of computing power / day can dig bitcoin worth 4.03 yuan
1.7715 * 4.03 = 7.14 yuan / day
since 2017, bitcoin has reached new heights. Yesterday (May 23), the value of bitcoin broke through the ¥ 16000 mark, hyping virtual currency, becoming a matter that the general public can participate in, And a little bit of technical level, both fried money, but also began to have the technical content of mining
as we all know, virtual currency has a numerical peak, the more difficult it is to dig. In fact, it's hard to judge whether to lose money or not if we continue to dig. Therefore, in the end how to dig, dig what can be the fastest back to this, this paper studies the above two core issues based on the current market situation
for mining machines, the most important thing is the graphics card. Generally, you can choose the most basic motherboard that supports 6 graphics cards, and later you can choose the more complex motherboard that supports more than 12 graphics cards. The specific suggestions are as follows:
1. CPU - CPU can choose the most basic and cheap CPU, as long as you can bring the system up normally, Generally, you can choose Intel's g3900 CPU with a unit price of about 200 yuan< Operating system is too laggy. If you use 6 graphics cards, you need at least 4G of memory. If you are 12 graphics cards, the windows operating system needs at least 8g of the memory. Otherwise, the system will be very stuck and then can not work normally. The Linux operation system can be 4G memory. < br > />2.
3. Motherboard - it is recommended for novices to directly choose the special mining motherboard of Yingtai series. The models are tb250 BTC with 6 card slots and tb250 btcpro with 12 card slots, as well as H81 series motherboard of Huaqing
4. Hard disk - SSD hard disk is needed for hard disk, because the reading speed is fast, and virtual memory needs to be set. SSD hard disk can improve some performance theoretically. If you use Windows system, you need at least 64GB, and Linux system can use 16GB
5. Operating system for windows, it is recommended that win10 system, corresponding to NVIDIA series and AMD Series graphics cards, can recognize up to 8 cards respectively. If the motherboard of 12 cards needs N cards and a cards to be mixed, then we can make full use of the motherboard graphics card slot
6. Graphics card - the mainstream mining graphics card models are amd Series graphics cards rx470, rx570, rx580, NVIDIA Series graphics cards gtx1060, gtx1070 and so on. It is recommended to choose 4G or more memory, and 8g is the best.
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
mining is actually equivalent to pasting envelopes. If you think about it, eight PhD students paste quickly, Or more than a thousand high school students
mining is to use the parallel computing function of graphics card to solve simple but huge mathematical problems
up to 7 cards can be mined by expansion card.
This is a three digit segmentation method, because western countries are used to add a comma every three digits to separate money, so as to avoid too many digits to see its value
three digit segmentation means that when a number is represented, three numbers are used as a paragraph, separated by commas or spaces. For example, 752259412 can be expressed as "752259412" or "752 259 412"
this is very convenient in English speaking countries, because in English speaking countries, the first three places are a thousand, the second three places are a million, and the third three places are a billion
and this comma is the thousand separator. According to the Western custom, people add a symbol to the number, so as not to see its value because there are too many digits. It is mainly aimed at financial professionals, such as professional accountants, fund managers, stock investors, etc. some professional people can know the specific amount at a glance through the thousand separator
extended data:
the history of Arabic numerals
around 500 A.D., with the rise and development of economy, culture and Buddhism, mathematics in Punjab, northwest of Indian subcontinent, has been in a leading position, originated in India
the astronomer abelhait has made a new breakthrough in simplifying numbers: he records numbers in one lattice. If there is a symbol in the first lattice, such as a dot representing 1, then the same dot in the second lattice represents 10, and the dot in the third lattice represents 100
In this way, not only the number symbols themselves, but also the order of their positions are of great significance. Indian scholars have also introced the symbol as zero. It can be said that these symbols and expressions are the forefathers of today's Arabic numerals In 700 A.D., the Arabs united under Islam conquered the surrounding nations and established the great Saracen empire from India in the east to Spain in the West. Later, the Islamic Empire was divided into two countries, the East and the Westbecause all the kings of the two countries reward culture and art, the capitals of the two countries are very prosperous, especially the eastern capital, Bagdad, where Greek culture from the West and Indian culture from the east come together. Arabs understand and digest the two cultures, thus creating a unique Arab culture
About 700 years ago, the Arabs conquered Punjab, and they were surprised to find that the mathematics of the conquered area was more advanced than them. How can we move these advanced mathematics to Arabia? Later, the Arabs introced this number to Spain. In the 10th century, it was spread to other European countries by Pope Gerber oriyak Around 1200 A.D., European scholars formally adopted these symbols and systems. By the 13th century, under the initiative of the mathematician Fibonacci in Pisa, Italy, ordinary Europeans also began to use Arabic numerals, which was quite common in the 15th centurythe shapes of Arabic numerals at that time were not exactly the same as those of Modern Arabic numerals, but they were relatively close. Many mathematicians spent a lot of effort to make them become the writing style of today's 1, 2, 3, 4, 5, 6, 7, 8, 9 and 0
Arabic numerals originated in India, but they spread to all directions through the Arabs, which is why they were later called Arabic numerals
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
