Amdnvidia a graphics card that can mine
for mining machines, the most important thing is the graphics card. Generally, you can choose the most basic motherboard that supports 6 graphics cards, and later you can choose the more complex motherboard that supports more than 12 graphics cards. The specific suggestions are as follows:
1. CPU - CPU can choose the most basic and cheap CPU, as long as you can bring the system up normally, Generally, you can choose Intel's g3900 CPU with a unit price of about 200 yuan< Operating system is too laggy. If you use 6 graphics cards, you need at least 4G of memory. If you are 12 graphics cards, the windows operating system needs at least 8g of the memory. Otherwise, the system will be very stuck and then can not work normally. The Linux operation system can be 4G memory. < br > />2.
3. Motherboard - it is recommended for novices to directly choose the special mining motherboard of Yingtai series. The models are tb250 BTC with 6 card slots and tb250 btcpro with 12 card slots, as well as H81 series motherboard of Huaqing
4. Hard disk - SSD hard disk is needed for hard disk, because the reading speed is fast, and virtual memory needs to be set. SSD hard disk can improve some performance theoretically. If you use Windows system, you need at least 64GB, and Linux system can use 16GB
5. Operating system for windows, it is recommended that win10 system, corresponding to NVIDIA series and AMD Series graphics cards, can recognize up to 8 cards respectively. If the motherboard of 12 cards needs N cards and a cards to be mixed, then we can make full use of the motherboard graphics card slot
6. Graphics card - the mainstream mining graphics card models are amd Series graphics cards rx470, rx570, rx580, NVIDIA Series graphics cards gtx1060, gtx1070 and so on. It is recommended to choose 4G or more memory, and 8g is the best.
The miner is better
-
the electricity charge for mining with graphics card is very high, and the performance is not high, so it can't even earn the electricity charge
-
mining is an investment more than time and speed. We should try to dig more money in the shortest time. Therefore, the professional mining machines of BTC now stress the characteristics of simple operation, small footprint and low power consumption. For example, Yingtai has developed a professional mining motherboard with a computing power of 23.488g/hash, and the proct model is btc-24gh< br />
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
while NVIDIA graphics card provides less computing resources, mainly through software optimization to achieve game acceleration. In addition, game n card simplifies some moles used in scientific computing (mining just belongs to this kind of Computing),
therefore, in the face of mining, which is a simple and high load operation, the N card with weak body will not work
for now, the design between AMD and NVIDIA is more and more similar. The a-card part absorbs the advantages of serial and branch judgment of n-card, and the n-card part also adopts the simple violence stack design of a-card. So who has the advantage is a mathematical proportion problem, whose graphics card is more accurate to the proportion planning of game resources, whose performance is better
so mining depends on the efficiency of the algorithm. A card is really good at an algorithm called SHA-256, which was used in violent decoding before (so a card also has a good performance in violent decoding)
unfortunately, in order to rece the power consumption, n card has actually simplified some scientific computing moles. As we said downstairs, the CPU is good at the work of branch judgment. N card no longer relies on itself, instead, it has been deleted, leaving this part of the work to the CPU to the processor, so the general computing performance is weaker than a card. As for the advantages of N card in the field of professional card for a card mentioned by some people, it mainly depends on the early investment and construction in the application of software in the past, that is, the early optimization is still in place, and now the old customers are still eating well
it is true that Tianhe first used 4870 as accelerator card, but there may be a mistake, that is, it was not NVIDIA's Tesla that was used by new Tianhe, but Titan, another supercomputer, which was not entirely Tesla processor, but also AMD's Haolong processor for collaborative computing. In fact, tianhe-2 uses Intel's Xeon Phi processor, neither amd nor NVIDIA.
in the second phase, the above old cards are still available, and the most perfect one is 470 480 570 580 low-end 560, which can also be used to dig lower models. There is no danger.
n card 1060 3G 6G is the most mainstream, 1050ti and 1070 are occasionally used. Especially luxury also used 1080, because the price of 1060 was almost 1080 at that time
mining is to split hash operation into several sub operations. A card can complete one operation with one instruction set, while n card needs three instruction sets to complete one operation. Therefore, the actual operation efficiency of a card is more than twice that of N card, which is close to three times
in fact, n card has greatly enhanced the mining efficiency in the Maxwell architecture, not inferior to a card. But the Maxwell architecture came out too late. When the earliest Maxwell architecture graphics cards, such as gtx750ti / 750, came into the market, the mainstream currencies could not dig out anything with graphics cards. Therefore, few people use n-card mining.
Gtx1070's video memory is 8g
The same price performance of the two brands of graphics card procts in the consumer market is not much different. N card has the advantages of low power consumption, mature driver and complete proct line (low, medium and high-end proct models), while a card has the advantages of high cost performance and strong computing power, but has the disadvantages of energy consumption and lack of high-end game procts. The following is a detailed introction:
1. For general game and entertainment users, the two brands of graphics card procts can meet their needs. The N / a two platforms have little difference in graphics card, so it is not necessary to tangle too much. Just choose a new graphics card suitable for your own price; If your budget is abundant and you have a certain pursuit of game performance, NVIDIA NVIDIA's graphics card is more worthy of purchase; In addition, when choosing procts, it is suggested to choose new platform procts, which have more advantages in new features and performance improvement
The main advantages of N card are low power consumption, mature driver and perfect proct line (low, medium and high-end procts); A card is more cost-effective, has strong computing power, has more advantages in drawing / mining, and has better image quality. However, at present, it is a short board in the game optimization drive, and there are few high-end game graphics procts, with poor energy consumption and low cost performanceThe difference is that the chips of the graphics card come from different manufacturers
