The following items are user-configurable only when the Overclock Profile item is set to [Manual]. CPU Frequency [XXX] (value is auto-detected) Indicates the frequency sent by the clock generator to the system bus and PCI bus. The bus frequency (external frequency) multiplied by the bus multiple equals the CPU speed. The value of this item is auto-detected by BIOS. The values range from 200 to 400. Refer to the following table for the correct Front Side Bus and CPU External Frequency settings. Selecting a very high CPU frequency may cause the system to become unstable! If this happens, revert to the default setting. PCI Express Clock [100MHz] Allows you to set the PCI Express clock. Key-in a decimal value between 100-200 MHz. Configuration options: [100Mhz] [101Mhz~[145Mhz] DDR Voltage [Auto] Sets the operating DDR voltage. Configuration options: [Auto] [2.60V] [2.65V] [2.70V] [2.75V] [2.80V] [2.85V] [2.90V] [2.95V] [3.00V] CPU Multiplier [Auto] Sets the operating CPU multiplier. The configuration options vary depending on the type of CPU installed.
