Common Options : Auto, Manual

Details

This BIOS feature is similar to AGP Driving Control, which allows you to set whether the AGP driving strength should be controlled by the chipset or manually configured. It is usually set to Auto by default, thereby allowing the chipset to assume control and automatically adjust the AGP driving strength to suit the installed AGP card.

However, for troubleshooting or overclocking purposes, you can set the AGP 4X Drive Strength to Manual to allow the manipulation of AGP Drive Strength values via the AGP Drive Strength P or N Ctrl BIOS feature.

Note that unlike AGP Driving Control, this feature usually has two to four different drive strength controls slaved to it. In contrast, AGP Driving Control usually comes with only a single control for AGP drive strength.
