SDRAM RAS Precharge Delay [3T] This item controls the idle clocks after issuing a precharge command to the SDRAM. The SDRAM RAS Precharge Delay parameter appears only when you set the SDRAM Configuration to [User Defined]. SDRAM Active Precharge Delay [6T] This item controls the number os SDRAM clocks used for SDRAM parameters. The SDRAM Active Precharge Delay parameter appears only when you set the SDRAM Configuration to [User Defined]. SDRAM Idle Timer [Infinite] Configuration options: [Infinite] [0T] [8T] [16T] [64T] Graphics Aperture Size [64MB] This feature allows you to select the size of mapped memory for AGP graphic data. Configuration options: [4MB] [8MB] [16MB] [32MB] [64MB] [128MB] [256MB] AGP Capability [4X Mode] When set to [4X Mode], this item allows 1066MB/s video data transfers through the AGP 4X interface card. When set to [1X Mode], the AGP interface only provides a peak data throughput of 266MB/s even if you are using an AGP 4X card. Configuration options: [1X Mode] [4X Mode] Video Memory Cache Mode [UC] USWC (uncacheable, speculative write combining) is a new cache technology for the video memory of the processor. It can greatly improve the display speed by caching the display data. You must set this to UC (uncacheable) if your display card does not support this feature, otherwise the system may not boot.
