English O.C. FSB1333 Core. 2 CPU Enable use of a CoreTM 2 CPU with 1333 MHz FSB through overclocking. To enable this feature, you must install DDRII 533 memory module(s) and a CoreTM 2 CPU. Disabled Disable the use of a CoreTM 2 CPU (1333 MHz FSB). (Default value) Enabled Enable the use of a CoreTM 2 CPU (1333 MHz FSB). CPU Host Clock Control Please note that if your system is overclocked and cannot restart, please wait 20secs. for automatic system restart or clear the CMOS setup data and perform a safe restart. Disabled Disable CPU Host Clock Control. (Default value) Enabled Enable CPU Host Clock Control. CPU Host Frequency (Mhz) 100MHz ~ 600MHz Set CPU Host Frequency from 100 MHz to 600 MHz. If you use a 533 MHz FSB processor, set "CPU Host Frequency" to 133 MHz. If you use an 800 MHz FSB processor, set "CPU Host Frequency" to 200 MHz. If you use a 1066 MHz FSB processor, set "CPU Host Frequency" to 266 MHz. Incorrect using it may cause your system broken. For power End-User use only! PCI Express Frequency (Mhz) Auto 90~150 Set PCI Express frequency automatically. (Default value) Set PCI Express frequency from 90 MHz to 150 MHz. System Memory Multiplier The adjustable range will vary based on the CPU FSB. Default value: Auto (set memory frequency by DRAM SPD data). Wrong frequency settings may cause system unable to boot. Clear CMOS to overcome wrong frequency issue. Memory Frequency (Mhz) The values depend on CPU Host Frequency (Mhz) and System Memory Multiplier setting. DIMM OverVoltage Control Please note that by overclocking your system through the increase of the DIMM voltage, damage to the memory may occur. Normal Supply DIMM voltage as DIMM required. (Default value) +0.1V ~ +0.7V Increase DIMM voltage by 0.1V ~ 0.7V. PCI-E OverVoltage Control Normal Supply PCI-E voltage as PCI-E required. (Default value) +0.1V ~ +0.3V Increase PCI-E voltage by 0.1V ~ 0.3V. FSB OverVoltage Control Normal Supply FSB voltage as FSB required. (Default value) +0.1V ~ +0.3V Increase FSB voltage by 0.1V ~ 0.3V. CPU Voltage Control Supports adjustable CPU vcore. The adjustable range is dependent on CPUs. (Default value: Normal) Please note that by overclocking your system through the increase of the CPU voltage, damage to the CPU or decrease in the CPU life expectancy may occur. Normal CPU Vcore Display your CPU's normal voltage. - 45 - BIOS Setup

English
O.C. FSB1333 Core. 2 CPU
Enable use of a Core
TM
2 CPU with 1333 MHz FSB through overclocking.
To enable this feature,
you must install DDRII 533 memory module(s) and a Core
TM
2 CPU.
Disabled
Disable the use of a Core
TM
2 CPU (1333 MHz FSB). (Default value)
Enabled
Enable the use of a Core
TM
2 CPU (1333 MHz FSB).
CPU Host Clock Control
Please note that if your system is overclocked and cannot restart, please wait 20secs.
for automatic system restart or clear the CMOS setup data and perform a safe restart.
Disabled
Disable CPU Host Clock Control. (Default value)
Enabled
Enable CPU Host Clock Control.
CPU Host Frequency (Mhz)
100MHz ~ 600MHz
Set CPU Host Frequency from 100 MHz to 600 MHz.
If you use a 533 MHz FSB processor, set "CPU Host Frequency" to 133 MHz.
If you use an 800 MHz FSB processor, set "CPU Host Frequency" to 200 MHz.
If you use a 1066 MHz FSB processor, set "CPU Host Frequency" to 266 MHz.
