Interface of miner's graphics card
1. It depends on whether the core turns yellow. Some parts of the new card will turn pale yellow, but at that time, the color of the protective paint is yellow. The core yellow of the mine card is yellow and burnt yellow caused by long-time and high-frequency use of heat and oxidation
2. Check the screw fixing plate
friends who have used independent graphics cards should know that the graphics cards are fixed on the chassis by screws, while most of the large-scale mining graphics cards are fixed by plastic ties, while the self use cards will not be fixed in this way
Interfaceinterface refers to the output interface of the graphics card. Before purchasing, you can ask the seller about the interface for connecting the display in daily use, because mining graphics cards usually do not use the display output interface
after the interface is determined, whether the interface has been used for a long time can be judged by checking whether there is st. If there is a lot of st, it will prove that the interface has not been used at all or recently

mine cards refer to the cards used to dig bitcoin. They are full loaded for a long time, with short service life and high load all day
the bitcoin mining machine is the computer used to earn bitcoin. This kind of computer generally has professional mining chips, and works by installing a large number of graphics cards, which consumes a lot of power. One of the ways to get bitcoin is to download mining software and then run specific algorithm to communicate with remote server to get corresponding bitcoin
Mining is a process of increasing bitcoin money supply. Mining also protects the security of the bitcoin system, prevents fraulent transactions, and avoids "double payment", which means spending the same bitcoin multiple times. Miners offer algorithms for bitcoin networks in exchange for the opportunity to get bitcoin rewards. The miners verify each new transaction and record it in the general ledgerexpansion slots for mining boards: 1 PCI Express x16 slot, 5 PCI Express X1 slots
support the installation of 6 graphics cards
Graphics card mining is a process of increasing the bitcoin money supply
the reason why the graphics card is used is that mining is actually a competition of performance and equipment. The mining machine is composed of graphics card array. With dozens or even hundreds of graphics cards, the cost of hardware and other costs is very high, and there is a considerable expenditure in mining
computers have professional mining chips, and most of them work by installing a large number of graphics cards, which consumes a lot of power. One of the ways to get bitcoin is to download mining software and then run specific algorithm to communicate with remote server to get corresponding bitcoin

the difference between mine card and ordinary graphics card
the most essential difference between special mine card and ordinary graphics card is whether there is a display interface, some have no or only one interface, and other mainstream HDMI, DVI, DP HD interfaces have been castrated, so they can only be used for mining, not suitable for playing games
the special mine card is only equipped with PCI-E 1.1 because it only aims at the general calculation application of mining with low bus bandwidth requirements × 16 interface, and the ordinary game graphics card is equipped with a higher specification of the mainstream pci-e2.0 / 3.0 specification
to see if the core is yellow, some parts of the new card will be light yellow, but at that time, the color of the protective paint is yellow, while the core yellow of the mine card is yellow and burnt yellow caused by high-frequency use of heat for a long time
1g version is the most popular. This model can well balance the mining speed and price
in other words, there are a lot of "mining machine graphics cards" on Taobao, because these graphics cards use less materials under the same core and basically unchanged hash speed, such as recing video memory to improve the performance price ratio (the size of video memory has little to do with the mining speed), which can shorten the time to recover the cost
in short, the graphics card of mining machine is the core of common high-end graphics card + the workmanship of low-end graphics card, or some cheap medium and high-end public graphics card.
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.
to run SLI, it is necessary to build a platform supporting SLI and build a SLI system, which requires: 1. A mainboard supporting SLI; 2. Two NVIDIA SLI certified graphics cards are required; 3. Windows XP operating system
although nforce4 SLI is not the first chipset to support SLI, Intel's Tumwater (e7525) motherboard belongs to the workstation / server level motherboard. Therefore, the motherboard of nforce4 SLI chipset is generally used for home users to build SLI systems. As far as the current situation is concerned, the prospect of SLI is quite bright. NVIDIA is ready to launch nForce 5 Intel chipsets supporting SLI, and via and SIS will also launch the so-called al PCI gfx technology, just waiting for NVIDIA to nod its head. So in the current situation, to build SLI platform, nforce4 SLI chipset is the choice of most players. The high speed digital interface of the motherboard is used to connect two graphics cards. Without its help, the SLI system is impossible
for graphics cards, they must pass NVIDIA SLI certification, and the SLI interface on PCB is the best explanation. You should pay attention when you choose a graphics card. According to NVIDIA, two graphics cards need to be of the same brand and model to start the SLI function. According to the current market situation, NVIDIA has separated three levels for us: high-end geforce 6800ultra, middle end geforce 6800gt and geforce 6800, and low-end geforce 6600GT. The graphics card score of geforce 6600GT SLI system is quite amazing, and it can realize 4-screen output. Such a device is quite lethal to consumers who want to configure low-end graphics workstations
finally, it is necessary to determine whether the power supply on your hand can provide enough current. According to the official instructions of NVIDIA, the power wattage required for the SLI system built by the high-end geforce 6800ultra is up to 500W ~ 550W. I believe everyone knows the power consumption of geforce 6800ultra very well, but now it is two geforce 6800ultra, so the power consumption is very large.
many miners can't get a card, so they have to turn to n card, especially GTX 10603gb, which is the most popular card. As a result, resources are scarce and prices continue to rise.
