— 21 —• Video RAM Cacheable< Disabled >Selecting Enabled allows caching of the Video BIOS ROM at C0000h to C7FFFh, resulting in bettervideo performance. However, if any program writes to this memory area, a system error may result.• 8 bit I/O Recovery Time< 1 >• 16 bit I/O Recover Time< 1 >The I/O recovery mechanism adds bus clock cycles between PCI-originated I/O cycles to the ISA bus.This delay takes place because the PCI bus is so much faster than the ISA bus.These two fields let you add recovery time (in bus clock cycles) for 16/8 - bit I/O.• Memory Hole At 15M-16M< Disabled >You can reserve this area of system memory for ISA adapter ROM. When this area is reserved, itcannot be cached. He user information of peripherals that need to use this area of system memoryusually discusses their memory requirements.• Passive Release< Enabled >When enabled, CPU to PCI accesses are allows during passive release. Otherwise, the arbiter onlyaccept another PCI master access to local DRAM.• Delayed Transaction< Disabled >The chipset has an embedded 32-bit posted write buffer to support delay transactions cycles. SelectEnabled to support compliance with PCI specification version 2.1.• AGP Aperture Size (MB)< 64 >The field sets aperture size of the graphics. The aperture is portion of the PCI memory address rangededicated for graphics memory address space. Host cycles that hit the aperture range are forwardedto the AGP without any translation.• CPU Warning Temperature< Disabled >This option lets you set the CPU temperature limit where the system will produce a warning indicatingCPU temperature has already exceeded.• Current System1 Temp (35 °C/ 95 °F)• Current System2 Temp (0 °C/ 32 °F)• Current CPU Temperature (50 °C/112 °F)These ready-only field reflect the function of the hardware thermal sensor that monitors the chio blocksand system temperature to ensure the system is stable.• Current FAN1 Speed (6136 RPM)• Current FAN2 Speed (0 RPM)• Current FAN3 Speed (0 RPM)These option and ready-only field show the current speeds in RPM (revolution per minute) for the CPUfan and chassis fan as monitored by the hardware monitoring IS.• VCore (1.68 V) / VTTP (1.48 V) / VCC (3.32 V) / + 5 V (5.18 V) / +12 V (12.28 V)These option and ready-only field show the current voltages in the voltage regulators and power supplyas monitored by the hardware monitoring IS.
