When you set the AI Overclocking Tuner item to [Manual], the related overclocking items appear. Configure System Frequency/Voltage AI Overclock Tuner CPU External Frequency (MHz) DRAM Frequency AGP/PCI Frequency (MHz) [Manual] [100] [Auto] [Auto] CPU VCore Voltage DDR Reference Voltage AGP VDDQ Voltage [Auto] [Auto] [1.50V] Performance Mode [Auto] CPU External Frequency (MHz) [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 and is not manually configurable. The values range from 100 to 400. Refer to the following table for the correct Front Side Bus and CPU External Frequency settings. Use the and keys to adjust the FSB. Table 4.4.1 FSB/CPU External Frequency Synchronization Front Side Bus FSB 800 FSB 533 FSB 400 CPU External Frequency 200 MHz 133 MHz 100 MHz DRAM Frequency [Auto] Allows you to set the DDR operating frequency. Configuration options: [266 MHz] [333 MHz] [400 MHz] [500 MHz] [533 MHz] [Auto] AGP/PCI Frequency (MHz) [Auto] Allows you to adjust to a higher AGP/PCI frequency for better system performance and overclocking capability. Configuration options: [Auto] [66.66/33.33] [72.73/36.36] [80.00/40.00] Selecting a very high AGP/PCI frequency may cause the system to become unstable! If this happens, revert to the default setting. CPU VCore Voltage [Auto] Allows you to select a specific CPU VCore voltage. Configuration options: [Auto] [1.9500V] [1.9250V] [1.9000V] [1.8750V] [1.8500V] [1.8250V] [1.8000V] [1.7750V] [1.7500V] [1.7250V] [1.7000V] [1.6750V] [1.6500V] [1.6250] [1.6000V] [1.5875V] [1.5750V] [1.5625V] [1.5500V] [1.5375V] [1.5250V] [1.5125V] [1.5000V] 4-18 Chapter 4: BIOS Setup
