Method 1: Setup up the CPU for the lowest speed for its brand. Turn the
power supply off and change the CPU. Then turn the system
on again, and set up the CPU parameters through CPU
SOFT MENU.
Method 2: Try turning the system on a few times (3~4 times) and the
system will automatically use its standard parameters to boot.
You can then enter BIOS SETUP again and set up the new
parameters.
Method 3: Since you have to open the computer case when you change
the CPU, it could be a good idea to use the CCMOS jumper
to erase the parameters of the original CPU and to enter
BIOS Setup to set up CPU parameters again.
Note : 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.
CPU Power Plane:
In the previous chapter we explained that the 586 CPUs can be divided
into two types: single voltage and dual voltage. This option will normally
auto-detect the type of your CPU, so you don
’
t need to make any changes.
ä
Single Voltage: Single voltage CPU
ä
Dual Voltage: Dual voltage CPU
ä
Set up the voltage via CPU Marking
