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:

(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,

(The possible setting is 3.0x, 3.5x, 4x, 4.5x, 5x, 5.5x, 6x, 6.5x, 7x, 7.5x, and
8x)
