3080 calculation force is unstable
The most advanced bitcoin mining machine, one to two years to dig out a bitcoin, bitcoin mining is now too difficult. If you want to dig, you can dig ether currency. Now it is steadily appreciating every day. According to the current development trend, it will be able to recover its capital in about seven months, and then it will be profitable< br />
Bitcoin is a kind of network virtual currency. Bitcoin network generates new bitcoin through "mining". In essence, the so-called "mining" is to use computers to solve a complex mathematical problem to ensure the consistency of bitcoin network distributed accounting system. Assuming that the mining computing power is 100 mhash / s and the total computing power is 4000 ghash / s per day, 3600 bitcoins can be g out every 24 hours
China's computing power has accounted for more than 75% of the world, that is to say, 75% of bitcoin in the world is made in China. How long does it take to dig a bitcoin
bitcoin used to be very good at "digging", which can be done by ordinary computer CPU, and it can automatically "solve problems" by downloading software. But with the rise of currency price, more and more people want to "solve the problem", and the difficulty of mining is also increasing. Now, the amount of computation needed to dig a bitcoin is beyond the reach of ordinary people. Ordinary computers can't afford it
instry insiders said that in 2014, 100 bitcoins were generated from 500000 yuan of electricity charge per day, and the cost of electricity charge alone was 5000 yuan per coin. But now, the same cost has more than doubled, and the electricity cost of each bitcoin is as high as 10000 yuan
in the generation mechanism of bitcoin, mining reward is decreasing. At the beginning of the birth of bitcoin, the miners could get 50 bitcoins for each page of the ledger, and then 25 bitcoins for each page of the ledger, decreasing in turn. It's like digging gold. At first, it's more and less. The time point at which each new reward is reced by half is called half bitcoin proction
assuming that the mining computing power is 100 mhash / s, the total computing power is 4000 ghash / s per day in 2014, and 3600 bitcoins are g out every 24 hours
now, we can understand the difficulty of bitcoin digging in this way, which is equivalent to 100 million dice throwing numbers less than 100 million and 50 million. Whoever throws them first will get the bookkeeping right. At this point, 1050 million is a hash value. The process of throwing dice is called hash collision. The unit of mining power is the number of hash collisions per second
at present, the computing power of bitcoin in the whole network has reached 2.36 billion hash collisions per second, which is equivalent to the number of water droplets in more than 200000 50 meter long standard swimming pools. But even with such a large amount of computing power, it will take about 10 minutes to hit a hash value that meets the requirements
in 2012, bitcoin's output was halved for the first time, and in July 2016, bitcoin's output was halved for the second time. At present, 12.5 bitcoins are awarded for recording one page of account book. The next halving will take place around 2020, and the total number of bitcoins will not increase by 2040, with a total of 21 million

According to the current computing power of the whole network, it takes 54436.5t of computing power to dig a bitcoin 24 hours, that is, one bitcoin a day< it requires 746 mining machines with the latest 73t capacity on the market to work together for 24 hours
the cost of mining mainly includes (mining machine cost / power cost). Now the latest miner is 22650 yuan, a miner consumes 77 kwh per day. At present, the price of mining machinery on the market is about 0.36 yuan, 28 yuan per day. The cost of mining bitcoin = mining machine price (22650)
mining bitcoin requires a professional site "mine" to place mining machines. The construction cost of placing about 3000 mining machines in a small professional mine is about 300 watts

unable to mine at home
the noise of 60-80 decibels will be proced by the mining machine in the working process. Mining at home is not feasible, the miner needs 24 hours of endless operation, so the temperature of the miner will be very high, the maximum temperature can reach 80 degrees. Therefore, mining needs a good environment to rece the temperature. Household electricity and electricity charges are high, and the cost is higher than the income. In addition, mining has a certain degree of professionalism, professionals need to carry out certain operation and maintenance to ensure the normal operation of the mining machine
the key to rece the mining cost is to purchase mining machines in batches and low electricity charges. Professional mine is built to ensure the operation of mining machinery. At present, the mainstream mining machinery manufacturers are bitcontinental Technology Co., Ltd. in Beijing and Jianan Yun Technology Co., Ltd. in Hangzhou. Mining machinery is proced in the form of appointment in futures. It is difficult for indivials to buy Mining machinery in small quantities on the official website. After years of development, the mining machinery market has formed a complete instrial chain. The price of mining machinery fluctuates with the price of money, and the power resources are basically distributed in the cheap western region. Getting cheap electricity prices requires personal resource advantages
the budget of this set is almost 8000, which is likely to be won. Now we mainly wait for 3080 to be officially put on sale, otherwise the price can not be estimated, because there will be differences in the prices of different brands at that time. If the budget is insufficient, then we have to choose the second and third tier brands. I've written so much about this problem, please don't forget to praise and pay attention to it. Thank you
everyone wants to buy this graphics card with high cost performance and strong performance, but the current proction and shipment volume is relatively small, so they can't buy it.
for i510400f, choose a graphics card of about 1500 yuan, such as ASUS or MSI,
the motherboards of these two brands are worth buying and trustworthy!
next, I recommend a more balanced configuration with 3080. In terms of positioning, 3080's performance is more than 2080ti, so it should be a flagship graphics card, and other accessories should not be too bad. If it's too bad, I'm sorry for such a good graphics card. As for the budget, I can't estimate it. As for 8000, it's impossible to meet it. The price trend can only be seen later, I dare not promise you now
the budget of this set is almost 8000, which is likely to be won. Now we mainly wait for 3080 to be officially put on sale, otherwise the price can't be estimated, because the price of different brands will certainly be different at that time. If the budget is insufficient, then we have to choose the second and third tier brands. I've written so much about this issue, please don't forget to praise and pay attention to it. Thank you
NVIDIA announced that it would postpone the launch of RTX 3070 on October 15, 2020, and officially launch it on October 29, 2020
the announcement of delaying the launch of RTX 3070 may be related to the confusion in the sale of RTX 3080. Retailers, e-businesses and official channels all over the United States almost sold out every second. Many players didn't buy the 3080 at the first time, and there were many scalpers selling RTX 3080 at a higher price on eBay, which made many players very dissatisfied
NVIDIA had to make an official apology for this situation, saying that it was not prepared for the unprecedented demand for new graphics cards
extended information:
NVIDIA has officially released 30 series graphics card RTX 3090 / 3080 / 3070. Previously, it was announced that 3090 will be available on September 24 and 3080 will be available on September 17
The RTX 3070 is 242mm long, 112mm wide and 2 slots thick. In terms of parameters, RTX 3070 has 5888 CUDA core, 1.73ghz acceleration frequency, 8 GB gddr6 video memory, 256 bit width, HDMI 2.1 interface and 3x DisplayPort 1.4A interface, 220W video card power and 650W recommended system powerthe new generation of 30 series graphics card adopts NVIDIA ampere architecture, which is based on Samsung's 8nm technology. Compared with the original Turing RTX architecture, NVIDIA ampere architecture has doubled the computing power. Each clock performs two shader operations, while Turing is one. The shader performance reaches 30 tflops single precision performance, while Turing is 11 tflops. NVIDIA ampere architecture doubles the throughput of light and triangle intersection. RT core achieves 58 rttflops, while Turing achieves 34 RT tflops
is generally stable within the range of 30 ℃. That is to say, the temperature of the CPU is 65 degrees. If the maximum temperature is 35 degrees in summer, the temperature of the CPU is allowed to rise to 30 degrees. And so on, if your ambient temperature is now 20 degrees, the CPU should not exceed 50 degrees. Of course, the lower the temperature, the better. No matter how much you overclock, don't make your CPU over 30 degrees above the ambient temperature< Now I want to add a few points:
1. Temperature and voltage
the increase in temperature is e to the fact that the calorific value of u is greater than that of the radiator. Once the calorific value and heat dissipation are in balance, the temperature will not increase. The calorific value is determined by the power of u, and the power is proportional to the voltage. Therefore, to control the temperature well, it is necessary to control the core voltage of CPU. However, it is easy to say that if the voltage is too low, it will cause instability, especially when the overclocking amplitude is large. Most of the time, when the CPU temperature does not reach the critical value, the blue screen of the system will restart. At this time, the main factor affecting the stability of the system is not the temperature, but the voltage. So how to set the voltage is very important in the limit of overclocking. If it is set high, the radiator will not hold. If it is set low, the u will not hold
2. The temperature measurement methods of different motherboards are not the same, even the motherboards of the same brand and model, e to the difference of the distance between the temperature probe and the CPU, the measured temperature also varies greatly. Therefore, it is unscientific to say how much temperature is safe in general. In my opinion, if you run super PI or 3dmark at higher room temperature in summer, you can pass the test as long as you can. You don't have to trust the temperature data of software test too much
3. What is stability? This has always been a hot topic that we like to discuss
computer is an electronic proct, and the coordination of its components is extremely delicate. No one can say that my computer is absolutely stable, and stability is relative. Overclocking in a reasonable range can resist the catastrophic consequences of most minor instability factors; In the extreme edge of hardware, overclocking, a very small current fluctuation may bring a series of follow-up reactions, and eventually your screen may turn blue or black:) how much frequency is stable? This problem only aims at the specific situation, and there is no formula to apply. It can only rely on experience and personal practice. So here's another reminder to some friends who ask "how much can my computer overclock?" they'd better try it according to the scientific overclocking steps<
generally, you can know it by entering the BIOS.
recommend several CPU temperature control software to you, and you can understand the temperature change.
1. Waterfall pro (download address: Sina Download Center) is an old computer cooling software with small volume and powerful function, which can effectively control the rise of CPU temperature and optimize CPU speed, Monitor CPU usage and power consumption< Second, cpuidle
cpuidle (download address: Sina Download Center) can significantly rece the operating temperature of CPU, prolong its service life, and rece the power consumption of CPU. Different from other energy-saving software, cpuidle can still play a significant role even in the case of overload< Softtool II (download address: Sina Download Center) is a green chip cooling software, which has the advantages of occupying less system resources and memory space, without any settings, and can be used directly after decompression< Vcool (download address: Sina Download Center) is a cooling software specially designed for AMD CPU. And it's a green software. It's very simple to use and takes up less system resources. The cooling effect of AMD CPU is good< 5. CPU cooling master (download address: Sina Download Center) is a compact CPU cooling software. The system kernel adopts assembly technology to optimize the CPU unit directly. It is suitable for all types of CPU procts and plays a good role in optimizing and protecting the CPU.
the situation you mentioned is generally caused by system software, memory and hard disk
1 if the computer doesn't want to install malicious software, or malicious programs are generated when surfing the Internet, it is suggested to use 360 guard, Jinshan guard and other software to clean up the garbage and kill malicious software. It's really not good. The problem caused by software can be solved by reloading and restoring the system
2 if you can't enter the system, you can go to the system and press F8 to select the last correct configuration (which can solve the error caused by the wrong driver installation) and the security mode with network connection (there is a network after entering, and then use 360 software to get it), which may be repaired
run the start menu at 3 o'clock, enter CMD, and at the command prompt, enter
for% 1 in (% windir% & # 92; system32\*. DLL) do regsvr32.exe / S% 1 and enter. Then let it run, it should be possible to solve<
4 recently, the computer has been poisoned, unstable software has been installed, and so on. It is recommended to completely eliminate the virus, remove the software that caused the problem, and then re install other versions. If not, it will be OK to re install the system.
5 the memory mole in the computer chassis is sty, disassemble the chassis, remove the memory mole, clean the memory finger, and then re install it, Maybe Cqjiang Yong summed up that old computers often have such problems)
6 the memory of the computer is broken after being used for a long time, it is not compatible to buy parallel memory, and it is suggested to replace the memory
hope to help you!!! Please step on it
