MP1CF: Maximum P1 Core Frequency
This location contains the maximum non-Turbo Boost core frequency for the processor.
The frequency should equate to the markings on the processor and/or the S-spec
speed even if the parts are not limited or locked to the intended speed. Format of this
field is in MHz, rounded to a whole number, and encoded in binary coded decimal.
Writes to this register have no effect.
Example: A 2.666 GHz processor will have a value of 2666h.

MP0CF: Maximum P0 Core Frequency
This location contains the maximum Turbo Boost core frequency for the processor. This
is the maximum intended speed for the part under any functional conditions. Format of
this field is in MHz, rounded to a whole number, and encoded in binary coded decimal.
Writes to this register have no effect.
Example: A processor with a maximum Turbo Boost frequency of 2.666 GHz will have
a value of 2666h.
