Advanced Chipset Features

The Advanced Chipset Features menu is used for optimizing the chipset functions.

WARNING: Do not change these settings unless you are familiar with the chipset.

AGP Aperture Size

This setting controls how much memory space can be allocated to AGP for video purposes. The aperture is a portion of the PCI memory address range dedicated to graphics memory address space. Host cycles that hit the aperture range are forwarded to the AGP without any translation. Settings:

4MB, 8MB, 16MB, 32MB, 64MB, 128MB, and 256MB

When set to 1x mode, the maximum transfer rate it at 266MB/s, and 2x mode transfers data at 533MB/s. AGP8x mode can be detected automatically once you plug in the AGP8x card. Settings: 4X, 2X and 1X
