Jumpers; Selecting The Cpu Frequency - AOpen MX3W-V User Manual

2.2 Jumpers

With the help of Celeron PPGA VID signal and SMbus, this motherboard is
jumper-less design.

2.2.1 Selecting the CPU Frequency

Celeron PPGA VID signal and SMbus clock generator provide CPU voltage
auto-detection and allow user to set CPU frequency through CMOS setup, no
jumper or switch is needed. The correct CPU information is saved into
EEPROM, with these technologies, the disadvantages of Pentium base
jumper-less design are eliminated. There will be no worry of wrong CPU
voltage detection and no need to re-open the housing if CMOS battery loss.
The CPU frequency selection is set by going into:
BOIS Setup ? Frequency/Voltage Control ? CPU FSB
(The possible setting is 66.8, 72, 75, 83.3, 90, 95, 100.2, 105, 107, 110, 112,
114, 117, 119, 121, 124, 125, 127, 129, 130, 133.6, 136, 138, 140, 145, 150,
and 155 MHz.)
BOIS Setup ? Frequency/Voltage Control ? CPU Ratio
(The possible setting is 3.0x, 3.5x, 4x, 4.5x, 5x, 5.5x, 6x, 6.5x, 7x, 7.5x, and
8x)
Core frequency = CPU Ratio * CPU FSB
