Which is better to mine

1.

The graphics card market in 2017 is the most special in recent years. In the past few years, no graphics card will increase its price by 100% a few months after its release. RX 580 has achieved this goal. Together with all the graphics cards below 3000 yuan, it has broken through the premium point in an irresistible manner. All this happened with the bitcoin price breaking through 3000 US dollars. After miners swept the RMB 2000 RX 580, the price of low-end RX 560 and even GTX 1050 Ti increased to varying degrees. However, is the price directly proportional to the ability of hash algorithm? Recently, we did a test to collect the new generation of graphics cards at various prices on the market, test the mining speed of Ethernet and bitcoin, and see which card has the highest cost performance

Different from the thousand yuan market, this wave of mining tide has a great impact on high-end graphics cards. In the test results, RX 580 and Rx 480 have almost reached the bottom of GTX 1070. Moreover, the price of Rx 580 is even competing with that of GTX 1070, so the miners directly swept the 3000 yuan market when GTX 1060 3gb / 6GB is out of stock, and GTX 1070 is basically out of stock. The more advanced GTX 1080 is also out of stock, but it's not clear whether the players are forced to go directly to the high-end card or the miners extend their claws to this market. The situation of GTX 1080 ti is only slightly improved, but it's not much better. However, not everyone can afford the 6000 yuan graphics card. Only the top players will be affected, but it's just a narrower choice. It's not the case that the rich can't buy it

summary:

to mine, the first choice is the graphics card with more than 3gb video memory, which is the basis. In addition, the core frequency will affect the mining speed. We have two GTX 1080 cards on hand, one is public version, and the other is MSI GTX 1080 gaming X. the operating frequencies of the two cards are 1885mhz and 1936mhz respectively. After testing, because of the frequency, the latter will be about 4% faster than the former in actual mining. The advantages of high-frequency graphics card are highlighted

So Xiaobian's opinions and suggestions are as follows:

the low-end card and the old architecture card are not suitable for mining. GTX 1080 ti is an extreme, with the most powerful performance, but the price is not suitable for large-scale procurement. The mining speed of a card with the same location is much faster than that of N card, The cost performance of GTX 1060 3gb is higher than that of GTX 1060 6GB. The frequency and the number of stream processors / CUDA have a great influence on the performance of the card. The size of video memory has no influence on the mining. It's enough. Different video cards will have different profits if they dig different coins. If you want to further explore, you need to test several currencies, Limited to space, we only select two representative currencies to test

as long as the mine disaster does not occur, the shortage will last for a long time. However, if there is a mine disaster, a large number of second-hand mine cards will directly enter the market. These cards are always running at full load and full speed, and their service life is greatly shortened compared with that of ordinary users. Even if the price is lower, they will roll over at any time, There is no need to start at all. Moreover, the second-hand market will be directly disrupted. At that time, it will be difficult for some normal users to get out of the second-hand market, and the deep-water fish's Dragon killing knife will explode the galaxy. Now it is said that NVIDIA is making some graphics cards without display output interface, which are provided to miners as mine cards. With a certain capacity, if the mine card still can't satisfy the miners, won't the miners buy the graphics card in the consumer market? The only function of these special mine cards is to prevent mine cards from flowing into the second-hand market, which can not alleviate the current shortage of graphics cards

The miner is better

1. 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

2. 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 />

3. However, the effect of n-card mining is not as good as that of a-card mining

it's not easy to dig now. The money g is not enough for the electricity bill

if you want to dig, you'd better join a mine pool. In this way, we can dig more

< / OL >

4. In terms of warranty, n card is generally guaranteed for 3 years, while a card is usually only guaranteed for 1 year
in terms of eth, a card generally needs to brush the BIOS to achieve the highest computing power, and it needs to install a special mining driver
the N card is easy to operate, and the driver can be installed at will. However, the price performance of a card will be higher than that of N card after digging eth
however, in terms of mining life, if eth can't dig in the future, a card may cost a lot. For the time being, a card can only dig Eth and Zec. Zec has proced professional mining machines. In the future, it may not be cost-effective to dig video cards. There are really few currencies that a card can dig. N card is different. Although eth is slightly lower than a card, n card supports many algorithms. There are more than 100 counterfeit coins that can be g. One day, Eth and Zec collapse, and you can continue to live by changing any currency. Aiminer supports both a-card and n-card mining.

5. CPU can be used to mine, but the efficiency of CPU mining is not as high as graphics card. In order to make money, absentees have to calculate the input-output ratio. The input-output ratio of mining with graphics card is higher, so we graally start mining with graphics card. Now you should understand why mining with graphics card does not use CPU.

6. You can install three graphics cards with PCI-E adapter. You can read the tutorial online. The cheapest graphics card is 7770, and the speed of a single card is 200. If you make three graphics cards, the average monthly income is about 1000-1200, because you don't need to pay for electricity, so this part is not excluded for you

7. Mining? Of course, the more SP, the better. But we should also pay attention to cost performance, otherwise we can't recover the cost of 6970

8. The computer has been connected to the Internet, and is WLAN normal<

you can try to update the WLAN Driver

you can try to turn off the WLAN and then turn it on in the BIOS

1. See if the NIC driver is broken. If the driver is broken, you need to re install the driver, download an offline driver or go to the official website to find the corresponding version of the driver

2 if it's not broken, just re-establish the connection. It is recommended that you follow the following methods

1. If the computer uses the client dial-up Internet, it is unable to realize wireless sharing (such as campus network client dial-up Internet)

2. Update your Windows system to the latest version

3. Uninstall the third-party wireless sharing software (such as cheetah, etc.), and use the system's own mobile hotspot function to share wireless

4 If it cannot be shared, please replace the wireless network card driver of the system
first of all, laptops are connected to mobile hotspots in the same way as wireless networks, which are all connected in WLAN. However, your situation should be that your computer is not connected to the network. Come again. The mobile hotspot option of laptop is the way that the laptop converts the connected network into a hotspot for other devices to connect. The premise of this option is that the laptop should be connected to the network

so your problem should be that you don't know how the notebook connects to the mobile hotspot

the solution is to connect at WLAN. When you can't solve the problem by using simple settings, you can try the following method, which is effective by testing
Press win-x to open the option box, select the administrator command prompt, open the command window, input
Netsh Winsock reset catalog command, press enter to display the reset success. Then restart the computer,
and try again whether you can connect the hotspot of the mobile phone. Basically, it can be solved<

hotspot settings are generally based on wireless network card, and it is recommended to use 360 free WiFi
if you use a desktop computer, or do not have a wireless network card, or do not turn on the wireless network card, you cannot use the hotspot
however, the description of your problem should be the corresponding hotspot. If you can't access the Internet, it is recommended to check whether the hotspot device can access the Internet normally

the answer is wrong. The reason why you can't turn on the hotspot is because you are using broadband dial-up. The hotspot of win10 can't be turned on if you connect a router, or if your network cable doesn't need to do anything, you can directly have a network. Or the next third-party software<

set the notebook WiFi as the WiFi hotspot, so that the mobile phone can connect the notebook WiFi hotspot to the Internet, but now it can't connect to the Internet normally, because the following problems have not been solved well:
1. Determine whether the notebook computer can connect to the Internet normally, that is, the "local connection" network connection is normal
2. Determine whether the laptop has a wireless network card and whether the wireless network card is turned on
3. Check whether the network share of "local connection" is set correctly
solution:
1. Check whether the "local connection" network is normal, as shown in the figure:

2. Re install the wireless network card driver and turn on the wireless network card switch
3. A. restart the computer, open WiFi, and select "wireless network connection" in "local connection" and "home network connection"
B. set up a hotspot to connect (be sure to connect here, otherwise the following one will pop up the network sharing error dialog box), As shown in the figure:

C. right click the "local connection" attribute and select "wireless network connection" from "home network connection" in the "sharing" tab, as shown in the figure:

D. disconnect the wireless hotspot connection and re connect,

first of all, you have to have a wireless network card, otherwise you can't launch the wireless bank!
