Cgminer is a professional Litecoin mining software that supports CPU/GPU mining, supports overclocking and adjusts fan speed. It is very powerful and can help users easily dig more Litecoin.
Win7 is the most suitable cgminer software. From a system perspective, cgminer only compiles 32 bits in the Windows platform, which is pure 32-bit software. If you put it on a 64-bit operating system, you should theoretically run better than 32-bit.
2, install the graphics card driverThe graphics card driver must be installed. As for the version of the graphics card installed, by experience, there is no problem with the latest graphics card. There are contrasts between the old and new versions in my debugging process, and there are no obvious differences. Download address: support.amd.com/zh-cn/download/
3, install the graphics card AMD-APP-SDKAMD-APP-SDK is AMD's graphics driver development kit. This software is purposeful. It is useful when debugging cgminer. download link:
Developer.amd.com/tools-and-sdks/heterogeneous-compuTIng/amd-accelerated-parallel-processing-app-sdk/downloads/#one, download according to your operating system.
4, debugging cgminer parameters (emphasis) 4.1 to be a good miner, we must choose a good poolA good Litecoin mine will also have a big impact on your income. There are many good mining pools in the country. There are fees and charges, and there is also a fee-free fee. At the beginning, the mineral pool I registered was a fish pond. It was relatively stable. Later I transferred it to the Litecoin mine with profit rewards. www.LTC1BTC.com/reg/xyabcgs (small recommended, use my recommended address to register, I You can get a little reward for you, you can get more extra profit rewards, win-win, and the income is improved.
4.2 Download cgminer softwareAfter the mine pond is selected, mining software is needed. The cgminer version of the Treaco coin can't exceed 3.7, which I saw in a tutorial. I have been using cgminer version 3.50, the situation is relatively stable. Download address: ck.kolivas.org/apps/cgminer/
The detailed description of the parameters of cgminer is believed that many students can find it on the Internet. I will not explain them one by one, but I will explain the key parameters and the parameters affecting the mining efficiency in detail below.
4.3 Write conf configuration file and bat batch fileThe following debugging is for 4 graphics cards, so there are 4 parameters.
Write in a text file and save it as myltc.conf and put it in the cgminer directory. The format is as follows:
{
"pools":[
{
"url": "mine pool address",
"user": "Your miner name",
"pass": "x"
}
],
"scrypt": true, [this parameter is a parameter necessary to dig Litecoin]
"kernel": "scrypt, scrypt, scrypt, scrypt",
"intensity": "17,17,17,17", [key parameter 1, several GPUs have several values]
"gpu-engine": "1050, 1050, 1050, 1050", [key parameter 2, several GPUs have several values]
"gpu-memclock": "200,200,300,300", [key parameter 3, several GPUs have several values]
"gpu-memdiff": "0,0,0,0",
"gpu-powertune": "0,0,0,0",
"thread-concurrency": "12284, 12284, 12284, 12284", [key parameter 4, several GPUs have several values]
"shaders": "1792, 1792, 1792, 1792",
"worksize": "256, 256, 256, 256",
"gpu-fan": "0-90, 0-90, 0-90, 0-90",
"gpu-threads": "1" [key parameter 5, only 1 value]
}
Write bat batch processing with text (just name go.bat, put it in the cgminer directory as the command to start cgminer), the content is:
setxGPU_MAX_ALLOC_PERCENT100
setxGPU_USE_SYNC_OBJECTS1
Cgminer-cmyltc.conf
The above two setx commands can only work if AMD-APP-SDK is installed. It enables the thread-concurrency parameter to exceed 8192 and the intensity to exceed 13. Otherwise, you will have a lot of HW hardware errors that will seriously affect your revenue.
4.4 Debugging cgminerBecause each graphics card has the physique of each graphics card, you must debug it yourself for your own graphics card. Other people's things are always others'.
The first step is to determine the thread-concurrency value. Method: Set [key parameter 1] intensity to "d, d, d, d", all other parameters are set to 0 or deleted (gpu-threads is set to 1), and the thread-concurrency value is continuously increased. Run go.bat once, until go.bat can't run normally, find its maximum value. This value is related to your memory. The larger the memory, the larger the value can be set. But for my R9270X graphics card, 2G memory is enough. Its size will affect the hardware error rate of the graphics card, but will not affect the speed of mining operations. Be sure to note that your memory cannot be less than the memory of your single graphics card.
The second step is to determine the intensity value. Method: Start the [Key Parameter 1] intensity setting from "14, 14, 14, 14" (the setting of 4 graphics cards, only one value for one graphics card), and run cgminer. Gradually increase the value, for example, "19, 19, 19, 19", observe the running status of cgminer, and find the most suitable value of intensity by the HW in the interface without error and the fastest calculation speed.
The third step is to determine the gpu-engine value. Method: After determining the intensity value and the thread-concurrency value, we will find the optimal value of [key parameter 2] gpu-engine. Starting from 750, in steps of 30, gradually increase the value, observe the running status of cgminer, and find out which value is the fastest computing speed of your graphics card.
The fourth step is to fine tune [key parameter 3] gpu-memclock. First set the value to "100, 100, 100, 100". This value has a certain influence on the speed of your operation. First increase the value and determine the optimal frequency. The computing speed of each GPU will be slightly different due to various graphics voltages or other reasons. Which GPU is low, you will slightly increase the corresponding gpu-memclock value, for example, from 200 to 250. Until the computing speed of each GPU is close to the same.
Finally, the remaining unmarked parameters can be deleted. Also, some people will ask, [key parameter 5] gpu-threads did not talk, gpu-threads value from 1 to 4, you can burn high incense on the 4th. Some cards are set to 1 most suitable, and some settings are 2 most suitable. You can try it. When I switch to 3, the computer is stuck.
Where to buy the Litecoin mining machineFirst of all, what kind of Litecoin mining machine you really need. Then go to the official website of the brand mining machine. For example: Lite mining machine L21 mining machine is produced by the currency network BW, you can first go to their official website to see, certainly sell. In addition, go to Huaqiang North to see, there are many mining machines there.
