Increasing Frequency and Decreasing Voltage

in frequency •  4 years ago 

This stage is much easier and safer. Our task will be to find the memory, core and voltage frequencies that allow the video card to consistently deliver the maximum possible hash rate. The word "continuous" is important here: a graphics card with all frequencies increased may work, but occasionally freezes and errors may occur. Therefore, we need to find a balance between performance and reliability; Fortunately, there is almost no chance of damaging the adapter at this point.

If you are mining on Windows, you will need the MSI Afterburner utility. As the name suggests, it works on both AMD and NVidia graphics cards. Install the software from the official website, restart the computer - you're ready.

Afterburner comes in different designs depending on the version, but the structure is always the same: You will see a series of categorized sliders eg "Voltage", "Clock", "Fan". Setting the voltage to 920 mV, the core clock to 1,000 MHz and the memory block to 2,000 MHz might be a good start. Check how the card reacts. You will then need to increase or decrease these values, depending on the memory chip manufacturer. If the video card fails, try increasing the voltage to 950 mV or decreasing the memory frequency to 1,950 MHz. If everything works fine, you can increase the frequency parameters a little.

In my experience, Samsung offers the best performance. Memory cards run continuously at 920 mV voltage, 1,100 MHz core clock and 2,100 MHz memory clock; temperatures and fan rotation speeds are also very reasonable (up to 68 ° C and 70% respectively). This combination provides an excellent hash rate at relatively low power consumption. If you are using Windows, you can check the memory manufacturer with the help of GPU-Z.
