Chapter 4

CPU Current Capability
CPU Current Capability provides wider total

power range for overclocking. A higher value

setting gets higher VRM power consumption

delivery.
A higher value brings a wider total power range

and extends the overclocking frequency range

simultaneously.

Suggestion: choose higher value when overclocking or under high CPU loading for extra

power support.

CPU Voltage Frequency
Switching frequency will affect the VRM

transient response and component thermal.

Higher frequency gets quicker transient

response.
Enable Spread Spectrum to enhance system

stability.
• VRM Fixed Frequency Range: 300–

550kHz

• Manual Frequency Step: 10kHz

Do not remove the thermal module when switching to Manual mode. The thermal

conditions should be monitored.

CPU/NB Load-line Calibration
Load-line is defined by Intel VRM spec and

affects CPU/NB voltage. The CPU/NB working

voltage will decrease proportionally to CPU/NB

loading. Higher load-line calibration could

get higher voltage and good overclocking

performance but increase the CPU/NB and

VRM thermal.
• Regular: 0%
• Medium: 25%
• High: 50%
• Ultra: 75%
• Extreme: 100%

The actual performance boost may vary depending on your CPU specification.

Do not remove the thermal module. The thermal conditions should be monitored.
