CGMiner 4.1.11 – This is a multi-threaded multi-bullet FPGA and ASIC miner for bitcoins, as well as the most popular miner for GPU / FPGA / ASIC. CGMiner – This is an open source GPU miner written in C and available on several platforms such as Windows, Linux and OS X. One of the things that make it extremely popular is the fact that it is based on the original Cpu code. Miner.

CGMiner includes overclocking, monitoring, fan speed control and remote interface features. Other features include self-discovery of new blocks using a mini-database, binary cores, multi-GPU support, and processor mining support. There are many other characteristics of this miner, which you can find out in this article about CGMiner.

If you compile cgminer with a version of CURL before 7.19.4 then some of the above will not be available. All are available since CURL version 7.19.4

If you specify the –socks-proxy option to cgminer, it will only be applied to all pools that don’t specify their own proxy setting like above

After saving configuration from the menu, you do not need to give cgminer any arguments and it will load your configuration.

Any configuration file may also contain a single
“include” : “filename”
to recursively include another configuration file.
Writing the configuration will save all settings from all files in the output.

CGMiner Review

Miner CGMiner is designed to work with graphics cards from AMD. Since he does not know how to extract currency using CUDA technology. If you own a PC or a farm with NVIDIA graphics cards, it is better to use Claymore’s Dual Miner.

Of the interesting features of this program it is worth noting the availability of tools for overclocking the GPU and even to control the speed of the coolers. It is recommended to use them very carefully.

Even CGMiner can provide debug information, automatically disable the “problem” worker, to work through a proxy, and use strategy Load Balance and Round Robin. The user is given the opportunity to specify the width of vectors, time periods for reconnection, to create artificial delays for routers and to configure a separate message output.

  • the lack of GUI (console application);
  • using the NeoScrypt algorithm, helps to achieve maximum values of MH/s;
  • availability of tools for overclocking the graphics card;
  • change parameters via the configuration file;
  • display a detailed log;
  • To simplify the work with the program, you can use the cgwatcher graphical shell.

Options for config CGMiner

Intensity the main indicator affecting the speed of the miner, its value is set from 0 to 20. It should be borne in mind that too high intensity can adversely affect the speed of mining, because it can exhaust all available memory and in fact, will reduce the speed of mining at best. At worst-will appear a large number of incorrect calculations and HW errors. Note that if the intensity is not set, CGMiner itself will dynamically adjust it taking into account the possibility of comfortable work on the PC.

Thread-concurrency controls the optimal amount of calculations that the scrypt algorithm can perform. It is initially configured to maximize the use of multiple streams of all Shader blocks of the graphics card that it has. The value should be a multiple of the number of Shader blocks of the graphics card, Respectively, if “thread-concurrency” is specified, then “shaders” can be removed. It is recommended that you spend some time searching for the best value for your graphics card in order to get the best performance

CGMiner GPU mining

There’s a new version of CGMiner git 5.3.1-tpruvot for the production of Decred using AMD and NVIDIA GPUs. This new version of the miner has to work better than the previously available CGMiner fork for DCR.

This fork comes with support for both protocols, the adoption of a ball, such as a formal Protocol, and more advanced getwork getwork via stratum. As mentioned above, the miner will work with graphics cards from AMD and NVIDIA GPU (using OpenCL and not CUDA).

Keep in mind that NVML monitoring only works in 64-bit version. When testing this version of the miner, we were able to achieve a higher hashrate on video cards from NVIDIA than when using tpruvot fork ccMiner for mining DCR. Those who produce using AMD graphics cards should not have any problems with the transition to this version of the miner. You will surely be able to get the best results when mining Decred, using pools with support of Gatework through Stratum.

CryptoNight algorithm for mining

The main task of Cryptonight is not to create a gap between PC users and owners of specialized ASIC devices during mining. Abadi and other cryptographers have developed memory-sensitive algorithms.

The main idea is to allocate a large block of data (Notepad) to RAM with an unpredictable sequence in it. The block should be large enough to make data storage more convenient than computing it every time it is accessed. The algorithm also needs to prevent internal parallelism, i.e., N simultaneous threads should require N times more memory at once.

The popular Scrypt algorithm also uses memory, but leaves the possibility of building powerful and relatively inexpensive computing devices for calculating this algorithm. In the case of CryptoNote, unlike Scrypt, each new block (64 bytes) depends on all the previous ones. The new algorithm requires about 2 MB of RAM, which is the minimum size of the L3 cache of modern processors. At the same time, this amount of RAM excludes the use of ASIC.

We must distinguish between CryptoNote and CryptoNight. CryptoNight is one of the implementations of the CryptoNote Protocol. On the algorithm “Kriptonit” built Monero (XMR), ByteCoin (BCN), Aeoncoin.

The advantages of production on this algorithm:

  • Smoothly decreasing emission.
  • Small time intervals between blocks;
  • The inability to mine on ASIC hardware.
  • The use of bundles of CPU+GPU for greater performance.
  • Fundamental differences from bitcoin, which contributes to the growth of interest in new cryptocurrencies.
  • Innovation profitable CryptoNight coin isolated from most of the altcoins on the old algorithms.
  • Profitability and expediency of production is higher than most other cryptocurrencies.
  • Less heating of the graphics card and processor than when mining on other algorithms.
