3.3 Other Installation for Your Reference
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 of CPU jumper-less design; you can set CPU frequency by
1MHz stepping CPU Overclocking in the BIOS.
CPU Core Frequency = CPU FSB
clock x CPU Ratio
. However, all CPU now sold in market belong to "Fixed
Multiplier". That means users can not adjust the CPU Ratio but change CPU FSB
clock to achieve overclocking only.
BIOS Setup > Frequency / Voltage Control > CPU Speed Setup
(Users will do the overclocking at their own risks!!)

CPU FSB (Adjustment
manually)
FSB = 100MHz-248MHz by 1MHz Stepping CPU Overclocking
Warning:
SIS 651 chipset
support maximum
533MHz (133MHz*4)
system bus and
66MHz AGP clock;
higher clock setting
may cause serious
system damage.
