AGP Drive Strength N Ctrl
Common Options : 0 to F (Hex numbers), 0h to Fh
Quick Review
This BIOS feature will only be activated if you set the AGP Drive Strength BIOS feature to Manual. It determines the N transistor drive strength of the AGP bus.
The drive strength is represented by Hex values from 0 to F (0 to 15 in decimal). The higher the drive strength, the greater the compensation for the motherboard's impedance on the AGP bus.
In conjunction with AGP Drive Strength and AGP Drive Strength P Ctrl, this function is used to bypass AGP dynamic compensation in cases where the auto-compensation circuitry cannot provide adequate compensation. Please check with your graphics card manufacturer if your card requires the N transistor drive strength to be manually set.
Incidentally, increasing the AGP drive strength will not improve the performance of the AGP bus. It is not a performance enhancing feature so you shouldn't increase the N transistor drive strength unless you need to.
