6.3 CPU Missing Sensor
The CPU Missing sensor is a discrete sensor reporting the processor is not installed. The most common instance of this event is due
to a processor populated in the incorrect socket.

4600/2600/2400/1600/1400 Product Families is the interconnect between processors.
The QPI Link Width Reduced sensor is used by the BIOS POST to report when the link width has been reduced. Therefore the
Generator ID will be 01h.
