How to put so many graphics cards in miner

1.

Why use graphics card to mine

compared with CPU, GPU is used for general purpose calculation. So it can stack hundreds of stream processors awesome. Each stream processor is like a small CPU. Although its ability to run complex programs is far from the power of CPU, it can not support many processors, so the actual performance, especially the single precision floating point performance is much stronger than that of CPU. p> However, as we have mentioned before, a card is very suitable for general computing such as virtual currency because it has many stream processors, and the speed of obtaining specific solutions is much higher than that of N card. Therefore, many miners rush to buy a card to calculate virtual currency for profit

of course, with NVIDIA's Pascal graphics card, n card's ability in mining virtual currency is not as different as a card before. So in the current situation that a card is generally out of stock, those mid-range N cards have become the second choice for miners

What are the disadvantages of mine card

finally, I want to talk about why we can't choose mine card when we are shopping for second-hand cards. Because the miners are mining bitcoin, the most important thing 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

in addition, the places where virtual currency is mined are mostly the places where multiple graphics cards gather. Thousands of graphics cards are constantly calculating in a room, and their heat is also quite huge. Miners can not 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

the result of doing so is that the graphics cards used for mining are lost prematurely. If you buy these graphics cards, the result will be unstable operation, restart and other things will continue to happen

moreover, at present, manufacturers also have strict requirements on mine cards, such as banning second-hand sales and shortening the shelf life. If users buy these mine card graphics cards, future maintenance will also be a big challenge

2. Mining machine
needs higher computing power, not the performance of graphics card. AMD and NVIDIA have the same price of graphics card, amd has higher computing power, so mining machine uses this kind of graphics card more, I hope it can help you

3. Now there are special mining boards
expansion slots for mining boards: 1 PCI Express x16 slot, 5 PCI Express X1 slots
support the installation of 6 graphics cards

4. 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. Can't you see this kind of machine

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.

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

7. The actions in bitcoin can be regarded as the use of graphics card to do continuous general computing, and the computational complexity is relatively low and quite repetitive. The stream processor used by graphics card is just suitable for such an algorithm. It's like constantly solving equations. The graphics card is 2000 middle school students, while the CPU is 8 math doctors. Although the mathematical knowledge of the doctor of mathematics is far more than that of the middle school students, the speed of solving medium-sized equations such as virtual currency is certainly not as fast as that of 2000 middle school students. Therefore, the more graphics cards, the more operations.

8. Cup is not as fast as graphics card, graphics card is not as simple as ASIC chip. At present, all the virtual currencies of SHA-256 algorithm are mined by ASIC chip, and some other algorithms can not run on ASIC chip, so there are still graphics card miner. The operation speed of cup, graphics card and ASIC is improved, but the function is decreased.
