The same model of different brands of graphics card mining

1. POW is g with CPU. The better CPU, the greater the probability of digging. POS is g with money in your wallet. It depends on the amount of money you have, the length of time you spend in your wallet, the length of time you spend online, and so on

2. How to build SLI system
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.

3. I'm a rookie, but I feel dizzy with so many configurations upstairs. I didn't set the configuration file, so I directly used DOS interface to find cgminer, and then
- O
mine pool address: Port
- U
user name
- P
123
- I
11. It's very simple. P. S. I
7870 + 7750
when I value exceeds 12, there is hw, and the total speed is about 400k$

4. Don't think about the frequency of the same model.
anyway, when you play a game, the highest price is ASUS graphics card, so you can't run the game, even if the lowest price model (such as gtx750750ti or 1050 and 1050ti) doesn't work.
so ordinary users don't think about the frequency of the same model, Choose the middle price
such as gtx1050ti, the low price is about 1000 yuan. There are 1300
gtx1066 graphics cards. Low 2000, high 2600

5. That is, different manufacturers have their own names and use their own cooling moles. All the graphics chips used are from NVIDIA. Manufacturers add their own technology of cooling, and other components used will be different. Basically the same, the best I think is ASUS player Country Series graphics card. The materials are military grade. Of course, the price is also high.

6. Of course, there is a difference
there may be great differences in workmanship, materials, PCB design level, output interface specification, heat dissipation scheme, video memory size, frequency, etc.
. There will also be differences in the physique of GPUs. Some manufacturers will give priority to GPUs with good physique and easy to overclocking for their own procts
only by looking at disassembly and evaluation can we understand the gap between procts of different manufacturers
there are many things that affect the quality of the graphics card. For the same type of graphics card, the PCB specifications of different manufacturers may not be the same, the materials and wiring used may be different, the quality of electronic parts may also be different, such as solid / liquid capacitors, and the quality of different shipment batches may not be the same< Working principle of graphics card:
1. From bus to GPU (graphics processing unit): send the data from CPU to Beiqiao (main bridge) and then to GPU (graphics processor) for processing
2. From
Video chipset to video
ram: send the processed data to video memory
3. From video memory to digital
analog
converter
(=
ram
DAC, random read-write storage D-A converter): read data from video memory and send it to ram
DAC for data conversion (Digital signal to analog signal). But if it is a DVI interface type graphics card, it does not need to go through the digital signal to analog signal. And direct output digital signal
4. From DAC
to monitor: send the converted analog signal to the display
display performance is a part of system performance. Its performance is determined by the above four steps. It is different from video
performance. If we want to distinguish strictly, the performance of display card should be determined by the middle two steps, because the data transmission of these two steps is inside the display card. The first step is that the CPU (the core of the computer composed of arithmetic unit and controller, called microprocessor or central processor) enters the display card, and the last step is that the display card sends data directly to the display screen< The full name of GPU is graphic
processing
unit. GPU is a concept relative to CPU. As graphics processing becomes more and more important in modern computers (especially in home systems and game enthusiasts), a special graphics core processor is needed. NVIDIA first put forward the concept when it released geforce 256 graphics processing chip. GPU makes the graphics card less dependent on CPU, and does part of the original CPU work, especially in 3D graphics processing
the core technologies adopted by GPU include hardware T & L (geometry conversion and lighting processing), cubic environment material mapping and vertex blending, texture compression and bump mapping, al texture four pixel 256 bit rendering engine, etc. GPU is mainly proced by NVIDIA and AMD.

7. The same model does not mean the same. First of all, the display chip has d5 and D3, and the display frequency may also be different. There are differences in bit width, power supply, manufacturer's workmanship, component selection and so on. If you play with al cards, you'd better have the same brand, the same model, exactly the same two pieces. If you install one piece, it's better for you to play with the graphics card, Send you a sentence: "cheap no good goods, good goods are not cheap." don't look at the same model, the price has a big gap, on behalf of the performance also has a big gap
