Chapter 3
CPU Power Phase Control [Standard]
Phase number is the number of working VRM phase. Increase the phase number under
heavy system loading to get more transient and better thermal performance. Reduce the
phase number under light system loading to increase VRM efciency.
[Standard] Proceeds to phase control depending on the CPU loading.
�Optimized Loads the ASUS optimized phase tuning prole.
[Extreme] Proceeds to the full phase mode.
[Manual Adjustment] Allows manual adjustment.
Manual Adjustment [Fast]
Select [Ultra Fast] for a faster response. The reaction time will be longer when [Regular] is
selected. Conguration options: �Ultra Fast �Fast �Medium �Regular
CPU Voltage Frequency [Auto]
Switching frequency will affect the VRM transient response and thermal condition. Setting a
higher frequency gets a faster transient response.
[Auto] Allows you to enable or disable the Spread Spectrum item.
�Manual Allows you to manually set the frequency with a 10k Hz interval.
VRM Spread Spectrum [Disabled]
This item appears only when you set the CPU Voltage Frequency item to [Auto] and
allows you to enable the spread spectrum to enhance system stability.
VRM Fixed Frequency Mode [xxx]
This item appears only when you set the CPU Voltage Frequency item to [Manual] and
allows you to set a xed VRM frequency. Use the <+> and <-> keys to adjust the value.
The values range from 200k Hz to 400k Hz with a 10k Hz interval.
CPU Power Duty Control [T-Probe]
[T-Probe] Maintains the VRM thermal balance.
[Extreme] Maintains the VRM current balance.
CPU Power Thermal Control [125]
A higher temperature brings a wider CPU power thermal range and extends the overclocking
tolerance to enlarge the O.C. potential. Use the <+> and <-> keys to adjust the value. The
values range from 125 to 135.
DRAM Current Capability [Auto]
A higher value brings a wider total power range, and extends the overclocking range
simultaneously. Conguration options: �100% �110% �120% �130%
DRAM Voltage Frequency [Auto]
Allows you to adjust the DRAM switching frequency. Assign a xed high DRAM frequency to
increase the O.C. range, or a low DRAM frequency for a better system stability. Conguration
options: [Auto] [Manual]
