CPU VID signal and
clock generator provide CPU voltage auto-detection and allows the user to set the CPU frequency through the
, 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.
