held in wait states while completing an access to a slow device. While
the originating master rearbitrates for the bus, other bus masters are
allowed to use the bus bandwidth that would normally be wasted
holding the master in wait states. Another advantage is that all posted
memory write data is not required to be flushed before the request is
accepted. Chipset has an embedded 32-bit post write buffer to support
delay transactions cycles. Select “Enabled” to support compliance
with PCI specification version 2.1.
AGP Aperture Size (MB): This option determines the effective
size of the AGP Graphic Aperture, which memory-mapped graphic
data structures can reside in.
Auto Detect DIMM/PCI Clk: When set to “Enabled”, system will
automatically turn off PCI and DIMM clock which is not use and
reduce electromagnetic interference.
Spread Spectrum Modulated: When set to “Enabled”, system
clock frequency will automatically be modulated which helps
reducing electromagnetic interference. Default is “Enabled”.
Current System Temperature: This is the current system
temperature reading. This feature gives you the ability to monitor
your system’s temperature without opening the chassis. This feature
required W83781D chip install.
Current CPU FAN/FAN2 SPEED: This is CPU FAN or FAN2
RPM (Revolution Per Minute) reading. This feature gives you the
ability to monitor conditions of CPU FAN and FAN2. This feature
required W83781D chip install.
Vcc3, Vccp, +5V, -5V, +12V, -12V: This is Vcc3(onboard 3.3
volt), Vccp (CPU Core voltage), +5V(power supply’s +5 volt), -
5V(power supply’s -5 volt), +12V(power supply’s +12 volt) and -
12V(power supply’s -12 volt) reading. This feature gives you the
ability to monitor condition of system’s power. This feature required
W83781D chip install.
After you have made your selections in the CHIPSET FEATURES
SETUP, press the <ESC> key to go back to the main program screen.
