NVIDIA graphics adapters, due to their design features , are currently less capable and make farm building several times more expensive than with AMD solutions. The main components of the farm are nearly the same as those of a regular computer, with several exceptions:. There are currently a great number of graphics cards on the market, which suit for mining.
The largest list of these graphics cards is available on [litecoin. Here you can see the basic data of the mining: Some graphics cards are already deprecated and they are impossible to find in the necessary number and condition.
We will discuss graphics cards which are available on the market, as it will give an opportunity to make a mining farm of a necessary capacity. The selection of optimal parameters of memory clock speed and core clock speed must be done individually for each graphics card. These parameters affect both the mining rate and the whole system stability. Also, overclocking affects temperature and energy consumption of the graphics cards. The more is the GPU overclocking, the more are the farm demands for the cooling system.
If the system has different card series, or cards of one series but by different manufacturers, conflicts are possible during launch and overclocking, which will affect the maximum speed and the whole farm stability. Hardware combinations for a farm also affect the hash rate. A correct choice of farm components like motherboard and RAM also increases the stability and the mining speed of a farm.
For example, as said before: When building farms, one should do some calculations to know the most profitable variant. You need to know energy consumption of the whole farm and calculate 24 hours charges for energy. Considering these calculations, you can draw a conclusion on the payback period. To make this task easier, there are many mining calculators: There are companies that provide their equipment capacity for a certain amount of money per month.
This way is relevant for crypto currencies, which have only CPU mining. It is profitable in two cases: Operating systems and mining software. OS installed on the mining farm may affect the crypto coins mining speed. Linux The most popular OS among miners. Monitoring tools are brought to the main screen. A detailed description of installation and setup is available here club. The right driver version choice is very important.
Sometimes particular driver versions lower the total computational capacity of the scrypt mining equipment. At the same time the others, on the contrary, allow to achieve high hash rate. There are several main mining programs - bfgminer, ufasoft miner , diablo miner, phoenix, guiminer, cgminer. The most flexible in configuring, stable and informative miner is CGminer. So we will discuss it. CGminer is managed via the command line.
To ensure that you do not need to reconfigure all the settings every launch or when you change the crypto currency, it is easier to create a.
The basic setup for the miner to work looks like this: Intensity is the key figure affecting the miner's work speed, its value is set from 0 to One must consider that a too high intensity can negatively affect the mining speed, because it MAY exhaust all available memory and actually reduce the mining speed in the best case.
In the worst case — there will appear a lot of miscalculations and HW errors. Take into account that if the intensity is not set, CGMiner will adjust it itself, dynamically, to provide an opportunity of convenient work with the PC. Thread-concurrency controls an optimal volume of calculations which a scrypt algorithm can do.
