Setting CPU Voltage and Frequency

Setting CPU Core Voltage
This motherboard supports Voltage ID (VID) function to detect CPU voltage
automatically during power-on. However, if users are willing to do overclocking,
we also provide a range from 1.10V to 1.85V in the BIOS. Sometimes increasing
the original core voltage a little bit will make CPU overclock more properly.
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!!)
