For Intel Celeron PPGA MMX processors, you can choose the following settings:
ä300 (66*4.5)
ä433 (66*6.5)
............
CPU bus speed above 66MHz/100MHz supported but not guaranteed due to the PCI
and chipset specs.
User defined external clock and multiplier factor:
ä User Defined
The wrong settings of the multiplier and external clock in certain circumstances may
cause CPU damage. Setting the working frequency higher than the PCI chipset or
processor specs, may cause abnormal memory module functioning, system hangs, hard
disk drive data lose, abnormal functioning of the VGA card, or abnormal functioning
with other add-on cards. Using non-specification settings for your CPU is not the
intention of this explanation. These should be used for engineering testing, not for
normal applications.
If you use non-specification settings for normal operation, your system may not be
stable, and may effect system reliability. Also, we do not guarantee the stability and
compatibility for settings that are not within specification, and any damage of any
elements on the motherboard or peripherals, is not our responsibility.
/ Turbo Frequency:
This item will only be displayed if your CPU external clock supports Turbo Mode.
The Turbo mode allows you to speed up the external clock by approximately 2.5%.
This feature is used to verify the design flexibility. It is a very important tool for test
units to verify CPU stability. Do not use this feature.
äDisabled: CPU external clock is operating within the normal limits.
äEnabled: CPU external clock is operating within the limits of the Turbo mode.
