AGPCLK / CPUCLK

Common Options : 1/1, 2/3, 1/2, 2/5

Quick Review

This BIOS feature allows you to set the ratio between the AGP clock speed and the CPU bus (also know as front side bus or FSB) clock speed. This allows you to keep the AGP bus speed within specifications (66MHz) while using a much faster CPU bus speed.

When the ratio is set to 1/1, the AGP bus will run at the same speed as the CPU bus. This is meant for processors that use the 66MHz bus speed, like the older Intel Celeron processors.

The 2/3 divider is used when you use a processor running with a bus speed of 100MHz. This divider will cut the AGP bus speed down to 66MHz.

The 2/5 divider is used when you use a processor running with a bus speed of 166MHz. This divider will cut the AGP bus speed down to 66MHz.

Generally, you should set this feature according to the CPU bus speed you are using. This means using the 1/1 divider for 66MHz bus speed CPUs, the 2/3 divider for 100MHz bus speed CPUs, the 1/2 divider for 133MHz CPUs and the 2/5 divider for 166MHz CPUs.
