Mainboard User’s Manual
10 Microprocessor
2.4. Microprocessor
The mainboard is designed to operate with the following processors:
Processor Type Speed FSB
AMD Athlon/Duron
600 MHz
∼
1.4 GHz
200 MHz
An onboard switching voltage regulator provides the required 1.3 to
3.5 volts for the processor. The processor sends five VID (Voltage
Identification) signals to the switching voltage regulator. The switch-
ing regulator generates the correct voltage for the processor.
2.5. CPU Packaging
Socket-462 CPUs are packaged in a PGA configuration.
2.6. Chipset
The P6F121 supports the VIA KT133/KM133 chipset. The chipset
comes in pairs—the North Bridge chip and the South Bridge chip.
