AGP/PCI Frequency Setting [Auto]

When set to [Auto], this field allows automatic selection of AGP/PCI frequency to enhance system performance and overclocking capability. The setting [Manual] allows you to manually select the AGP/PCI frequency. If the system becomes unstable, return to the default setting [Auto]. When this item is set to [Manual], the AGP/PCI Frequency (MHz) item appears. Configuration options: [Auto] [Manual]

AGP/PCI Frequency (MHz) [66.66/33.33]

This item appears only when the AGP/PCI Frequency Setting is set to [Manual]. This field allows you to select a higher AGP/PCI frequency for better system performance.

Selecting a very high AGP/PCI frequency may cause the system to be unstable!

CPU VCore Setting [Auto]

This field determines if the CPU Vcore is automatically scaled or set manually by the user. The default for this field is [Auto], so the CPU vcore voltage is set for maximum performance without stressing the CPU. Configuration options: [Manual] [Auto]

CPU VCore [1.750V] (for Willamette), [1.500V] (for Northwood)

When the CPU VCore Setting parameter above is set to [Manual], the CPU VCore item allows you to select a specific CPU core voltage. This field is not accessible when the CPU VCore Setting is set to [Auto]. Depending on the OVER_VOLT jumper setting (see page for the jumper location and settings), the CPU core voltage options vary for both Willamette and Northwood processors. See the following table:
