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
External Frequency 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 Bus Frequency
CPU Ratio
4x, 7x… 17x, 18x, 20x
CPU FSB
(Adjustment manually)
FSB = 100MHz - 400MHz by 1MHz

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.
Warning:
SiS 661FX chipset support maximum 533MHz (133MHz*4) system bus;
higher clock setting may cause serious system damage.
