▍ BIOS Setup ▶ C1E Support To enable this item to read the CPU power consumption while idle. Not all processors support Enhanced Halt state (C1E). ▶ SVM Support This item is used to enable/ disable SVM. ▶ AMD Cool'n'Quiet The Cool'n'Quiet technology can effectively and dynamically lower CPU speed and power consumption. ▶ C1E Support To enable this item to read the CPU power consumption while idle. Not all processors support Enhanced Halt state (C1E). ▶ Adjust CPU FSB Frequency (MHz) This item allows you to select the CPU Front Side Bus clock frequency (in MHz). ▶ OC Stepping This item will be enabled after you set the overclocking frequency in the "Adjust CPU FSB Frequency (MHz)". And the following items will appear. This items will help the system to overclock step by step after system booting up. ▶ Start OC Stepping From (MHz) This item is used to set the initial FSB clock. The system will boot with the initial FSB clock, and start to overclock from initial FSB clock to set FSB clock that you set in "Adjust CPU FSB Frequency (MHz)" step by step. ▶ OC Step This item is used to set how many steps for FSB colck overclocking. ▶ OC Step Count Timer This item is used to set the buffer time for every step. ▶ Adjust CPU Ratio This item is used to adjust CPU clock multiplier (ratio). It is available only when the processor supports this function. ▶ Adjusted CPU Frequency (MHz) It shows the adjusted CPU frequency. Read-only. ▶ Adjust CPU-NB Ratio This item is used to adjust CPU-NB ratio. ▶ Adjusted CPU-NB Frequency (MHz) It shows the adjusted CPU-NB frequency. Read-only. ▶ CPU Core Control This item allows you to select the number of active processor cores. ▶ OC Genie Lite Setting this item to [Enabled] allows the system to detect the maximum FSB clock and to overclock automatically. If overclocking fails to run, you can try the lower FSB clock for overclocking successfully. 3-20

BIOS Setup
▍
C1E Support
To enable th±s ±tem to read the CPU power consumpt±on wh±le ±dle. Not all proces-
sors support Enhanced Halt state (C1E).
SVM Support
Th±s ±tem ±s used to enable/ d±sable SVM.
AMD Cool’n’Qu±et
The Cool’n’Qu±et technology can effect±vely and dynam±cally lower CPU speed and
power consumpt±on.
C1E Support
To enable th±s ±tem to read the CPU power consumpt±on wh±le ±dle. Not all processors
support Enhanced Halt state (C1E).
Adjust CPU FSB Frequency (MHz)
Th±s ±tem allows you to select the CPU Front S±de Bus clock frequency (±n MHz).
OC Stepp±ng
Th±s ±tem w±ll be enabled after you set the overclock±ng frequency ±n the “Adjust CPU
FSB Frequency (MHz)”. And the follow±ng ±tems w±ll appear. Th±s ±tems w±ll help the
system to overclock step by step after system boot±ng up.
Start OC Stepp±ng From (MHz)
Th±s ±tem ±s used to set the ±n±t±al FSB clock. The system w±ll boot w±th the ±n±t±al FSB
clock, and start to overclock from ±n±t±al FSB clock to set FSB clock that you set ±n
“Adjust CPU FSB Frequency (MHz)” step by step.
OC Step
Th±s ±tem ±s used to set how many steps for FSB colck overclock±ng.
OC Step Count T±mer
Th±s ±tem ±s used to set the buffer t±me for every step.
Adjust CPU Rat±o
Th±s ±tem ±s used to adjust CPU clock mult±pl±er (rat±o). It ±s ava±lable only when the
processor supports th±s funct±on.
Adjusted CPU Frequency (MHz)
It shows the adjusted CPU frequency. Read-only.
Adjust CPU-NB Rat±o
Th±s ±tem ±s used to adjust CPU-NB rat±o.
Adjusted CPU-NB Frequency (MHz)
It shows the adjusted CPU-NB frequency. Read-only.
CPU Core Control
Th±s ±tem allows you to select the number of act±ve processor cores.
OC Gen±e L±te
Sett±ng th±s ±tem to [Enabled] allows the system to detect the max±mum FSB clock and
to overclock automat±cally. If overclock±ng fa±ls to run, you can try the lower FSB clock
for overclock±ng successfully.
