CPU VID signal and
SMbus
clock generator provide CPU voltage auto-detection and allows the user to set the CPU frequency through
the BIOS setup, therefore no jumpers or switches are used. The disadvantages of the Pentium based jumper-less designs are
eliminated. There will be no worry of wrong CPU voltage detection.
