The CPU working voltage will decrease proportionally to CPU loading. Higher value gets a higher voltage and better overclocking performance, but increases the CPU and VRM thermal conditions. This item allows you to adjust the voltage range from the following percentages to boost the system performance: 0% (Regular), 25% (Medium), 50% (High), 75% (Ultra High), and 100% (Extreme). Configuration options: [Auto] [Regular] [Medium] [High] [Ultra High] [Extreme] The actual performance boost may vary depending on your CPU specification. CPU Fixed Frequency [XXX] This item allows you to set a fixed CPU frequency. Use the <+> or <-> keys to adjust the value. The values range from 200kHz to 350kHz with a 50kHz interval. CPU Power Phase Control [Auto] Allows you to set the power phase based on the CPU.
