Setting CPU Voltage and Frequency
Setting CPU Core Voltage
This motherboard supports Voltage ID (VID) function to detect CPU voltage
automatically during power-on.
Setting CPU Frequency
This motherboard is CPU jumper-less design, you can set CPU frequency through
1MHz stepping CPU Overclocking in the BIOS. CPU Core Frequency = CPU FSB
clock x CPU Ratio. However, all CPU now selling in the market belong to "Fixed
Multiplier". That means users can not adjust the CPU Ratio but only change CPU
FSB clock to achieve overclocking.
(Users do the overclocking at their own risk!!)
BIOS Setup > Frequency / Voltage Control > CPU Speed Setup
CPU Ratio
From 5.5x to 16.5x step 0.5x; 17x to 18x
step 1x
CPU FSB
(Adjustment manually)
FSB= 100MHz-255MHz by 1MHz Stepping

Note: With CPU speed changing rapidly, there might be faster CPU on
the market by the time you received this installation guide. This table
is kindly for your references only.
Note: Some CPU fans
do not have sensor pin so
they cannot support fan
monitoring.
