The following item appears only when you set the AI Overclocking item to [Manual]. CPU Frequency [200] Displays the frequency sent by the clock generator to the system bus. The value of this item is auto-detected by the BIOS. The values range from 200 to 450. FSB/CPU External Frequency Synchronization Front Side Bus FSB 1066 FSB 800 FSB 533 CPU External Frequency 266 MHz 200 MHz 133 MHz DRAM Frequency [Auto] Allows you to set the DDR2 operating frequency. Configuration options: [Auto] [DDR2-400MHz] [DDR2-533MHz] [DDR‑667MHz] Selecting a very high DRAM frequency may cause the system to become unstable! If this happens, revert to the default setting. PCI Express Frequency [Auto] Allows you to set the PCI Express frequency. This item is set to [Auto] by default. Configuration options: [Auto] [90]...[150] CPU VCore Voltage [Auto] Sets the operating VCore voltage.
