Mining external graphics card
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
Through a specific program and algorithm, using the computer graphics card calculation rate, a large number of calculations are carried out in the selected mine pool to generate data packets
The first step in setting up mining equipment is to choose the right hardware. This article will focus on GPU (graphics card) mining, of course, you can use CPU or ASIC equipment mining. Amd graphics card architecture is very beneficial to mining. NVIDIA card is not suitable for mining because of its low hash rate. The best NVIDIA graphics cards are less than 0.5 megahash. Notebook Hardware mining is not as good as NVIDIA card, which is a bad option for mining. You need to use a desktop system for mining. There is a desktop system to ensure adequate cooling of the hardware
the graphics card or card needs to be able to match the motherboard, and the power supply must have enough PCI-E connectors. Before determining the graphics card, pay attention to these. In order for the system to cool down sufficiently, you need to remove the cover of the chassis in order to get better heat dissipation. This is what people call "open air rig.". If you can aim the system at a fan or air conditioner, you can make the device cooler when it's running, thus extending its life and keeping it efficient
2. The CPU is used to perform mining tasks. Because the CPU needs many transistors to execute various instructions, many transistors are idle in a cycle. The speed is relatively slow
3, in order to enhance the ability of displaying images, the graphics card saves a lot of transistors that have nothing to do with the display function, so the graphics card can only display pictures, but it is much faster than the CPU in the task of displaying pictures. BTC needs to perform the same task as the graphics card, so the mining of the graphics card is faster than the CPU, So a card is more suitable for mining.
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.
The mine card is aging seriously, and its performance is lower than that of ordinary graphics card. Compared with ordinary graphics card, there are various faults
There are some differences between them: the graphics card specially designed for computing virtual currency (also known as mining) enhances the computing power of virtual currency and can run for a long time without problems compared with ordinary graphics card. But some abilities such as graphics processing and video rendering are weakened2. There is a difference in the service life of the two: the second-hand graphics card used for mining and circulating to the trading market has the same specifications as the ordinary graphics card of the same model, but after a long time of mining, the hardware life has been greatly reced, and the purchase of this kind of graphics card may have problems at any time
extended information:
reasons for the poor cost performance of second-hand mine cards:
1. The most important thing for miners to mine bitcoin is to seek profits. Therefore, the graphics card they use is running and calculating all the time, and its strength is far greater than that of daily game applications. In other words, running such a calculation for one day is equivalent to running a graphics card for one month
2. Most of the places where virtual currency is mined are places where many graphics cards gather. Thousands of graphics cards are constantly calculating in a room, and their heat value is also huge. Miners can't choose the chassis with good heat dissipation conditions like ordinary consumers, so that the heat can be released smoothly. In this way, the graphics cards can still operate for 7 * 24 hours under high temperature conditions, It also deepens its aging degree
3. Although the price of second-hand mine card is low, the hidden danger is too big. The performance of second-hand mine card has been mercilessly squeezed by the mine owner, and its service life has been greatly reced. Moreover, because it belongs to mine card, it can not enjoy the after-sales service of the manufacturer
