Auto Detect DIMM/PCI Clk –
When
enabled
, any DIMM/PCI clock not in use
will be disabled to reduce EMI radiation.
Spread Spectrum –
The default is the optimal value determined by the system
designer to reduce EMI radiation peak. Users should not attempt to change it.
CPU Host Clock –
This option lets you select the CPU/PCI clock.
The chipset
supports only the 66 and 100 MHz CPU bus clock. With this option, the bus clock
can be extended from 66 MHz to 75 or 83.3 MHz, or from 100 MHz to 103 up to
140 MHz for internal test.
Over-clocking may cause serious system damage.
System Hardware Monitor
The onboard hardware monitor allows you to observe the current temperature of
the CPU, current speeds (in RPM, rotation per minute) of the system and CPU
fans, as well as the various operating voltages. (If the fan is not installed, 0 RPM
will be shown.)
CPU Warning Temperature -
Once the CPU temperature exceeds the
temperature specified, a warning will be issued via the speaker and the operating
CPU speed will be slowed down to ease the situation.
CPU FAN Warning Speed -
Once the speed of the CPU cooling fan falls below
the
speed specified (in RPM, rotation per minute), a warning will be issued via the
speaker.
System 5V Alarm –
When
<4.75V or >5.25V
is selected,
a warning beep will be
issued via the speaker once the system board operating voltage falls below 4.75V or
rises above 5.25V.
