English 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. - 49 - BIOS Setup
