PCI Express Frequency (Mhz)
Allows you to control the PCIe clock frequency. This item is configurable only if the CPU Host Clock
Control option is enabled.
Auto Sets the PCIe clock frequency automatically. (Default)
SYC Sets the PCIe clock frequency SYC with CPU.
ASYC Fixs the PCIe clock frequency to 100 MHz.
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.
High Speed DRAM DLL Settings
Provides two different memory timing configurations. If your system becomes unstable after you
overclock the DDR2 memory, select Option 1 or Option 2 to help make your system more stable.
Option 1 Memory Timing Configuration 1. (Default)
Option 2 Memory Timing Configuration 2.
DDR2 OverVoltage Control
Allows you to to set memory voltage.
Normal Supplies the memory voltage as required. (Default)
+0.1V ~ +0.4V Increases memory voltage by 0.1V to 0.4V at 0.1V increment.
Note: Increasing memory voltage may result in damage to the memory.
FSB OverVoltage Control
Allows you to set the Front Side Bus voltage.
Normal Supplies the FSB voltage as required. (Default)
+0.1V ~ +0.3V Increases FSB voltage by 0.1V to 0.3V at 0.1V increment.
CPU Voltage Control
Allows you to set the CPU voltage. Normal sets the CPU voltage as required. The adjustable range
is dependent on the CPU being installed. (Default: Normal)
Note: Increasing CPU voltage may result in damage to your CPU or reduce the useful life of the
CPU.
Normal CPU Vcore
Displays the normal operating voltage of your CPU.
