4.3.4 DIGI+ Power Control ASUS DIGI+ Power Contol allows you to adjust VRM voltage and frequency modulation to enhance reliability and stability. It also provides the highest power efficiency, generating less heat to extend component lifespan and to minimize power loss. To launch DIGI+ Power Contol, click DIGI+ Power Control on the AI Suite 3 main screen. CPU screen 1 4 Help 2 5 3 1 CPU Load-line Calibration It allows you to adjust the voltage range to control the CPU Load-line. Adjust to a high value for system performance or to a low value for power efficiency. 2 CPU Current Capability CPU Current Capability provides wider total power range for overclocking. A higher value brings a wider total power range and extends the overclocking frequency range simultaneously. 3 CPU Power Phase Control Increase phase number under heavy system loading to get more transient and better thermal performance. Reduce phase number under light system loading to increase VRM efficiency. 4 CPU Power Thermal Control A higher temperature brings a wider CPU power thermal range, and extends the overclocking tolerance to enlarge overclocking potential. 5 CPU Voltage Frequency Switching frequency will affect the VRM transient response and component thermal. Higher frequency gets quicker transient response. 4-10 Chapter 4: Software support Chapter 4
