Many miners who have already begun to receive the first dividends from their farms are beginning to wonder: “How can you improve efficiency and profitability of your home enterprise?”. It is worth noting that there are several ways to achieve this result:
- installation of additional computing equipment;
- replacement of existing farms with more productive ones;
- installation of equipment in places with cheap electricity;
- flashing and overclocking of graphics cards.
Naturally, in order to achieve the maximum profit, you must follow all of the above tips. If the first three items are all clear, then the fourth one raises some questions, especially for beginners. Within the framework of this material, we just talk about overclocking of the graphics cards’ memory. Let’s take a closer look at what it is, what it gives and how to do it at home.
(please, click the topic to scroll down to it)
- What is the overclocking of a graphics card and what is it needed for?
- Procedure of overclocking the graphics card, software and settings
- Changing the memory frequency settings
- Adjustment of power consumption parameters
- Coolers and cooling system
So, graphics cards are computing equipment, they respectively differ in power, amount of built-in memory, etc. The speed at which a video card can perform calculations is measured in hashrates. Manufacturers of graphics cards, at the software level, limit their real performance. That is, suppose, out of the box the speed will be 24MH/S, but after the overclocking procedure, this figure can be at the level of 26-27MH/S. It may seem not a significant increase, but suppose, if there are 5 or 6 video cards in a single farm, then in the global perspective, the result will differ materially.
In the beginning, you need to install special software, the program is called MSI Aftefburner. It will be easy to understand it for any person who knows how to use a computer at the user level. Here is its appearance:
The interface, though simple, but it has everything you need:
- Temperature Limit;
- Memory Clock;
- Core Clock;
- Core Voltage;
- Fan speed;
- Power Limit.
In the market there are a huge number of different video cards and they are also reflashed in different ways. On some, performance improvement is achieved by adjusting the RAM frequency. Here the big role is played by the manufacturer of operative memory. Ideally, if the RAM in the video card is from the South Korean giant (Samsung). They are quite amenable to overclocking, without loss of stability. There is no single meaning, you need to try and test your equipment in the field. Start the mining process and observe how the adjustments influence it.
How can anyone achieve increased productivity, while reducing power consumption? Such a scenario is possible, but only under certain conditions. For example, when mining Ethereum, you can turn off the graphics core, then the power consumption will decrease, and the memory frequency, on the contrary, will grow.
After the video card is overclocked, you should take care of the cooling system. In MSI Aftefburner there is a whole section that is responsible for the operation of coolers. In this section you can make adjustments using a special schedule.
It should be understood that the higher the fan speed, the faster it will fail. But we strongly advise not to regret it, as buying a new powerful graphics card for mining will be much more expensive than replacing one cooler. Do not allow the equipment to overheat, this could damage it.
The process of overclocking the graphics card 1060 and other miners is not anything complicated. In order to do it yourself, you just need the desire to learn, to experiment. To do this, elementary knowledge in the PC is enough. Increasing the productivity of equipment, you can achieve a significant result.
