Quick Review

This BIOS feature allows you to overclock the AGP and PCI buses, even if Intel stamps its foot petulantly and insist that it is not meant for this purpose. While it does not give you direct control of the bus clocks, it allows some overclocking of both AGP and PCI buses.

Please note that while this BIOS feature allows some adjustment of the AGP and PCI bus speed, it does not allow you to modify individual clocks. Whatever you set using this BIOS feature affects both buses.

When this BIOS feature is set to Default, the AGP and PCI buses run at their normal speeds of 66MHz and 33MHz respectively.

When this BIOS feature is set to 63.88/31.94MHz, the AGP and PCI buses run at lower speeds of 63.88MHz and 31.94MHz respectively.

When this BIOS feature is set to 68.05/34.02MHz, the AGP and PCI buses run at higher speeds of 68.05MHz and 34.02MHz respectively.

When this BIOS feature is set to 69.44/34.72MHz, the AGP and PCI buses run at higher speeds of 69.44MHz and 34.72MHz respectively.

When this BIOS feature is set to 70.83/35.41MHz, the AGP and PCI buses run at higher speeds of 70.83MHz and 35.41MHz respectively.

When this BIOS feature is set to 72.22/36.11MHz, the AGP and PCI buses run at higher speeds of 72.22MHz and 36.11MHz respectively.

When this BIOS feature is set to 73.60/36.80MHz, the AGP and PCI buses run at higher speeds of 73.60MHz and 36.80MHz respectively.

For better performance, it is recommended that you set this BIOS feature to 73.60/36.80MHz. This overclocks the AGP and PCI buses by about 10%, which should not cause any stability problems with most AGP and PCI devices. But if you encounter any stability issues, use a lower setting.

However, please note that if you use this BIOS feature to overclock the AGP and PCI bus, Intel automatically disables the Burn-In Mode or Host Burn-in Mode BIOS feature, which allows the overclocking of the processor and memory modules.
