When this area is reserved, it cannot be cached. Setting options: Disabled, Enabled. Delayed Transaction The chipset has an embedded 32-bit posted write buffer to support delayed transactions cycles so that transactions to and from the ISA bus are buffered and PCI bus can perform other transactions while the ISA transaction is underway. Select Enabled to support compliance with PCI specification version 2.1. Setting options: Enabled, Disabled. Delay Prior to Thermal When the CPU temperature reaches a factory preset level, a thermal monitoring mechanism will be enabled following the appropriate timing delay specified in this field. With the thermal monitoring enabled, clock modulation controlled by the processor's internal thermal sensor is also activated to keep the processor within allowable temperature limit. Setting options: 4 Min, 8 Min, 16 Min, 32 Min. AGP Aperture Size (MB) This setting controls just how much system RAM 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. The option allows the selection of an aperture size of 4, 8, 16, 32, 64, 128, and 256 (MB). 4X Override This setting allows you to manually set the AGP mode of your system.
