* Note that 1.0 GHz = 1000 MHz

Proper voltage must be supplied for reliable operation. It may be supplied by a regulator integrated in the motherboard, or by a voltage regulator module (VRM) installed in Header 8 on the motherboard.

If the regulator is integrated in the motherboard, it must be Voltage ID (VID) programmable to allow the processor to program the correct voltage during power-on.

If the motherboard has Header 8, then a VRM must be installed in the header to power the processor. Most VRMs are VID-programmable. If your motherboard has a fixed-voltage VRM, its output voltage must match the processor requirements.

Since the operating voltage of Pentium III processors may be changed as the processor goes through stepping changes, VID-programmable voltage regulators are the preferred solution.
