through SoftMenu
™
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 SoftMenu
™
III.
Method 2: Since you have to open the computer case when you change the CPU, it would be a good idea
to use the CMOS clearing 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 SoftMenu
™
III again to set up the
parameters all over again.
Power Supply:
This option allows you to switch between Default and User Define voltages.
Default: The system will detect the CPU type and select the proper voltage automatically. When it is
enabled, the option “CPU 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 “CPU
Core Voltage” and “DDR Voltage” option lists by using the arrow up and arrow down keys.
This option allows you to switch between Default and User Define voltages.
CPU Fast Command Decode:
Two options are available: at Normal  to Fast or at Fast  to Normal. This will depends which state
you choose. If you set this item from “at Fast” to “to Normal”, when you reboot the system and finish
the POST process, the state will change to your new setting (Here’s to Normal). After that, if you go to
view the BIOS menu again, you will see this item shows “at Normal”, if you press the <Enter> key,
you’ll see the two options: at Normal  to Fast, and the default setting is at Normal. If you set this item
from “at Normal” to “to Fast”, and go through the same process we mentioned before, you will see this
item shows “at Fast”, if you press the <Enter> key, you’ll see the two options: at Fast  to Normal, and
the default setting is at Fast. You can select item if you want CPU decode address is faster or normal
speed. We suggest you choose to Normal for greatest stability. Should you want increased performance
then you can select to Fast. You have to set the jumper on the motherboard called “CROM” pin 1 and pin
2 short, then you can see this item appear in this menu.
