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. 
Warning: To avoid 
possible CPU damage 
caused by overheat, CPU 
Overheat Protection 
circuit had been 
especially designed on 
this motherboard. 
System will automatically 
power off when this 
motherboard detects the 
CPU temperature higher 
than 97 degrees 
centigrade.
