BIOS Setup
The increase by 2.5% of the CPU speed is not a standard feature of this product. It is
only for use by our development department to verify that the CPU is able to work
normally when CPU speed, operating temperature and power supply are 2.5% higher or
lower than the standard values. This is to guarantee product stability. We require the
manufacturer of the Clock Generator to meet the demands of our development
department and to add a TURBO Frequency feature used for testing purposes by our
R&D department. Of course, you can use this feature to test the stability of your own
system, but after you have tested the product, we recommend that you set it back to its
normal value in order to guarantee system stability.
/ External Clock:
ä66MHz (1/2)
ä100MHz(1/3)
ä112MHz (1/3)*
ä124MHz (1/3)*
ä133MHz (1/4)*
CPU bus speed above 66MHz/100MHz supported but not guaranteed due to the PCI and
chipset specs.
/ Multiplier Factor:
You can choose the following multiplier factors:
ä 2.0 ä 2.5
ä 6.5 ä 7.0
However, differences will exist because of the various brands and types available.
/ SEL100/66# Signal:
This default setting is "High" at 100MHz, and "Low" at 66MHz. When you want to
try a higher multiplier factor at 100MHz and cannot choose it in the "High" state,
you can set it to the "Low" state.
