AGP 3.0 Calibration Cycle

Common Options : Enabled, Disabled

Quick Review

This BIOS feature controls the AGP 3.0 calibration cycle feature of the motherboard chipset. It is only found in motherboards that support the AGP 3.0 standard.

When enabled, the motherboard chipset will periodically initiate a dynamic calibration cycle on the AGP 3.0 bus. This allows the AGP 3.0 bus to maintain its timings and signal integrity.

When disabled, the motherboard chipset will not initiate any dynamic calibration cycle on the AGP 3.0 bus. The AGP 3.0 bus timings and signal integrity may suffer from changes in voltage and temperature during operation.

As the dynamic calibration cycle maintains the AGP 3.0 bus' timings and signal integrity, it is highly recommended that you leave it at the default setting of Enabled.

However, please note that this feature is only implemented if both motherboard chipset and AGP graphics card are operating in the AGP 3.0 mode. It is automatically disabled when the AGP 2.0 mode is used.
