2-4 Tweaker Whether the system will work stably with the overclock/overvoltage settings you made is dependent on your overall system configurations. Incorrectly doing overclock/overvoltage may result in damage to CPU, chipset, or memory and reduce the useful life of these components. This page is for advanced users only and we recommend you not to alter the default settings to prevent system instability or other unexpected results. (Inadequately altering the settings may result in system's failure to boot. If this occurs, clear the CMOS values and reset the board to default values.) && CPU Clock Control Allows you to manually set the CPU base clock in 1 MHz increments. (Default: Auto) Important: It is highly recommended that the CPU frequency be set in accordance with the CPU specifications. && Spread Spectrum Control Enables or disables CPU/PCIe Spread Spectrum. (Default: Auto) && CPU Ratio Mode (Note) Allows you to set the core ratio for all CPU cores or individual cores. (Default: All cores) && CCD0 CCX0/1 Ratio (Note) Allows you to manually set the core ratio for the CPU CCX0, 1 cores. This item is configurable only when CPU Ratio Mode is set to Per CCX. (Default: Auto) && CPU Clock Ratio Allows you to alter the clock ratio for the installed CPU. The adjustable range is dependent on the CPU being installed. && GFX Clock Frequency (Note) Allows you to alter the frequency for the GPU. After you alter the GFX Clock Frequency settings, make sure to adjust the GFX Core Voltage settings. (Default: Auto) NOTE: The adjustable range is dependent on the CPU being installed. Auto lets the BIOS automatically configure this setting. && GFX Core Voltage (Note) Allows you to alter the voltage for the GPU. (Default: Auto) NOTE: The adjustable range is dependent on the CPU being installed. Auto lets the BIOS automatically configure this setting. (Note) This item is present only when you install a CPU that supports this feature. - 23 -

Tweaker
Whether the system will work stably with the overclock/overvoltage settings you made is dependent on your overall
system configurations. Incorrectly doing overclock/overvoltage may result in damage to CPU, chipset, or memory
and reduce the useful life of these components. This page is for advanced users only and we recommend you not to
alter the default settings to prevent system instability or other unexpected results. (Inadequately altering the settings
may result in system's failure to boot. If this occurs, clear the CMOS values and reset the board to default values.)
&
CPU Clock Control
Allows you to manually set the CPU base clock in 1 MHz increments. (Default: Auto)
Important:
It is highly recommended that the CPU frequency be set in accordance with the CPU
specifications.
&
Spread Spectrum Control
Enables or disables CPU/PCIe Spread Spectrum. (Default: Auto)
&
CPU Ratio Mode
(Note)
Allows you to set the core ratio for all CPU cores or individual cores. (Default: All cores)
&
CCD0 CCX0/1 Ratio
(Note)
Allows you to manually set the core ratio for the CPU CCX0, 1 cores. This item is configurable only when
CPU Ratio Mode
is set to
Per CCX
. (Default: Auto)
&
CPU Clock Ratio
Allows you to alter the clock ratio for the installed CPU. The adjustable range is dependent on the CPU
being installed.
&
GFX Clock Frequency
(Note)
Allows you to alter the frequency for the GPU. After you alter the
GFX Clock Frequency
settings, make
sure to adjust the
GFX Core Voltage
settings. (Default: Auto)
NOTE: The adjustable range is dependent on the CPU being installed.
Auto
lets the BIOS automatically
configure this setting.
&
GFX Core Voltage
(Note)
Allows you to alter the voltage for the GPU. (Default: Auto)
NOTE: The adjustable range is dependent on the CPU being installed.
Auto
lets the BIOS automatically
configure this setting.
(Note)
This item is present only when you install a CPU that supports this feature.
