5. Setting CPU Voltage & Frequency
Setting CPU Core Voltage
This motherboard supports CPU VID function. The CPU core voltage will be automatically
detected and the range is from 1.1V to 1.85V. It is not necessary to set CPU Core Voltage
Setting CPU Frequency
You can set CPU frequency through the BIOS setup.
BIOS Setup > Frequency / Voltage Control > CPU Clock
Core Frequency = CPU FSB Clock * CPU Ratio
CPU Ratio
2x, 2.5x, 3x, 3.5x, 4x, 4.5x, 5x, 5.5x, 6x, 6.5x, 7x, 7.5x, and 8x
CPU FSB
100~132MHz, 133~166MHz.
