Setting CPU Voltage and Frequency
Setting CPU Core Voltage
This motherboard supports Voltage ID (VID) function to detect CPU voltage
automatically during power-on and the range is from 0.8375V to 1.6V. It’s not
necessary to set CPU core voltage.

necessary to set CPU core voltage.
Setting CPU Frequency
This motherboard is 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.

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.
(Users will do the overclocking at their own risks!!)
