First, go to BIOS to check first. Normally MSI MB BIOS default setting is Enable. And then follow the below steps:<br />1. Close all applications and ensure that Windows OS is idle mode. (Pres Ctrl + Alt + Delete and select the Performance tab to verify CPU usage is 0%).<br />2. Right click My Computer and select, "Properties."<br />3. Under the General tab and inspect installed processor and speed. If Intel SpeedStep technology is enabled, two processor speeds will be listed. The first speed listed is the specified speed of the processor. The second speed is the current operating speed. The second speed will be less than the 1st speed (See picture). This indicates that Intel SpeedStep technology has effectively reduced the processor voltage and core frequency, it can decrease average power consumption and average heat generation. If Intel SpeedStep technology is off then both processor speeds will be equal (See picture).
