If everything is set, you can further move to the next voltage point, which, on my GTX 1080, is 800mV. These settings can potentially damage your card or crash your applications.įor the stability and safety of my graphics card, I will keep my voltage at 812 mV.Īfter understanding how the Voltage/Frequency curve works, its time for you to fine-tune your voltage value point-by-point.Īs an example, my GTX 1080 runs If we go to a step-down, my GPU will run Alternatively, you can change the frequency level of to or you can lower the frequency from to This way, your GPU will not waste any power on nearly no frequency improvement.Īfter you have selected your desired voltage and frequency, close the curve and move on to step four, to test the stability of the GPU.

Remember, it is not recommended to increase the frequency of the GPU too high or lower the voltage below 200 mV. You can lower the voltage by selecting the square-shaped boxes, and lower the frequency at that voltage by dragging that box upwards or downwards. To change the voltage value and frequency, click on one of the silver boxes with your mouse and drag it up or down to adjust the setting. If you look closer, you can see silver, square-shaped boxes. If you increase the voltage, your GPU will consume more power, thereby leading to increased temperatures and potential thermal throttling. The dotted red line, on the other hand, displays the current-voltage and the frequency value of your GPU.įor example, at 825 mV, my GTX 1080 will operate at 1664 Mhz. Here, the x-axis shows the voltage in millivolts (mV), and the y-axis display frequency in megahertz (MHz). In MSI Afterburner, you can either click the button or press CTRL + F key to open the curve editor as shown below. The real undervolting process begins from here. Step 2: Playing with the Voltage/Frequency Curve Select the yellow dots to open the curve.
