BIOS Setup 3-3
Power Supply:
This option allows you to switch between CPU default and user-defined voltages. Leave this setting to
default unless the current CPU type and voltage setting cannot be detected or is not correct. The option
“
User Define ” enables you to select the Core Voltage manually.
CPU Core Voltage:
This item selects the CPU core voltage.
ATTENTION: A wrong voltage setting may cause the system unstable or even damage the CPU. Please
leave it to default settings unless you are fully aware of its consequences.
DDR Voltage:
This item selects the voltage for DRAM slot.
Chipset Voltage:
This item selects the NB core voltage.
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.
Disable Unused PCI Clock:
This option disables the clock of PCI slot that is not in use.
[Enabled]:
The system automatically detect the unused DIMM and PCI slots, and stop sending clock
signal to these unused PCI slots.
[Disabled]: The system always send clock signal to all PCI slots.
NOTE:
Set this option to [No] setting if there are adapters that cannot be automatically detected by the
system and will cause malfunction.
Spread Spectrum:
Two options are available: Disabled Enabled. The default setting is Disabled . For EMC
(
E
lectro-
M
agnetic
C
ompatibility) testing, you may need to adjust these options for optimal results. We
do not recommend you change the default, except for special reasons. Some values you select may cause
system instability under some situations. Please be careful.
