Normally, we do not recommend that you use the “User Define” option to setup CPU speed and
multiplier factors. This option is for setup of future CPUs whose specifications are still unknown. The
specifications of all present CPUs are included in the default settings. Unless you are very familiar with
all CPU parameters, it is very easy to make mistakes when you define the external clock and the
multiplier factor by yourself.
Solution in case of booting problem due to invalid clock setup:
Normally, if the CPU clock setup is wrong, you will not be able to boot. In this case, turn the system off
then on again. The CPU will automatically use its standard parameters to boot. You can then enter the
BIOS Setup again and set up the CPU clock. If you can’t enter the BIOS setup, you must try turning the
system on a few times (3~4 times) or press “INSERT” when turning on, and the system will
automatically use its standard parameters to boot. You can then enter BIOS SETUP again and set up the
new parameters.
When you change your CPU:
This motherboard has been designed in such a way that you can turn the system on after having inserted a
CPU in the socket without having to configure any jumpers or DIP switches. If you change your CPU,
normally you just have to turn off the power supply, change the CPU and then set up the CPU parameters
through SOFT MENU
™
III. However, if the new CPU is slower than the old one (and is the same brand
and type), we offer you two methods to successfully complete the CPU change operation.
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 SOFT MENU
™
III.
Method 2: 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.
Attention: After setting up the parameters and leaving the BIOS SETUP, and having verified that the
system can be booted, do not press the Reset button or turn off the power supply. Otherwise the BIOS
will not read correctly, the parameters will fail and you must enter SOFT MENU
™
III again to set up
the parameters all over again.
CPU Power Supply:
This option allows you to switch between CPU default and user-defined voltages.
➤
➤➤
➤
CPU Default: The system will detect the CPU type and select the proper voltage automatically. When
it is enabled, the option “Core Voltage” will show the current voltage setting that is
defined by the CPU and this will not be changeable. We recommend using this CPU
default setting and not changing it unless the current CPU type and voltage setting can
not be detected or is not correct.
➤
➤➤
➤
User Define: This option lets the user select the voltage manually. You can change values of the
“Core Voltage” option lists by using the Page Up and Page Down keys.

Two options are available: 1 and 4. This item lets you set cache buffer for CPU data processing. If you
are not well acquainted with this item setting, please leave it on the default setting (4).
