GA-P31-ES3G Motherboard - 48 -
O.C. FSB1600 CPU
Enable use of a CPU with 1600 MHz FSB through overclocking. You must install the FSB 1600
MHz CPU with DDR2 800 (or above) memory module(s).
Auto Set this item to Auto. Then save the changes and restart your computer.
During the POST, a message will appear asking if you want to enable the use
of a FSB 1600 processor. Press <Y> to confirm or <N> to reject. Or press any
key to continue the POST. (Default)
Disabled Disable this function.
Enabled Enable this function.
CPU Host Clock Control
Enables or disables the control of CPU host clock. Enabled will allow the CPU Host Frequency
item below to be configurable. Note: If your system fails to boot after overclocking, please wait for
20 seconds to allow for automated system reboot, or clear the CMOS values to reset the board to
default values. (Default: Disabled)
CPU Host Frequency (Mhz)
Allows you to manually set the CPU host frequency. This item is configurable only if the CPU
Host Clock Control option is enabled. The adjustable range is from 100 MHz to 700 MHz.
For an 800 MHz FSB CPU, set this item to 200 MHz.
For a 1066 MHz FSB CPU, set this item to 266 MHz.
For a 1333 MHz FSB CPU, set this item to 333 MHz.
Important It is highly recommended that the CPU frequency be set in accordance with the CPU
specifications.
PCI Express Frequency (Mhz)
Allows you to manually set the PCIe clock frequency. The adjustable range is from 90 MHz to
150 MHz. Auto sets the PCIe clock frequency to standard 100 MHz. (Default: Auto)
Performance Enhance
Allows the system to operate at three different performance levels.
Standard Lets the system operate at its basic performance level.
Turbo Lets the system operate at its good performance level. (Default)
Extreme Lets the system operate at its best performance level.
System Memory Multiplier (SPD)
Allows you to set the system memory multiplier. Options are dependent on CPU FSB. Auto sets
memory multiplier according to memory SPD data. (Default: Auto)
Memory Frequency (Mhz)
The first memory frequency value is the normal operating frequency of the memory being used;
the second is the memory frequency that is automatically adjusted according to the CPU Host
Frequency (Mhz) and System Memory Multiplier settings.

System Voltage Control
Determines whether to manually set the system voltages. Auto lets BIOS automatically set the
system voltages as required. Manual allows all voltage control items below to be configurable.
(Default: Manual)
