OK. Seeing you asked :-)

- Always ensure the PIC stays within the guaranteed operating limits
specified by the data sheet when the PIC is operating.

This is not PC CPU overclocking country - there is almost always
minimal gain and significant risk of pain in exceeding these specs. If
you want a faster PIC buy a faster PIC. The price differene is usually
small or even negative. If the fastest PIC is too slow use another
processor or learn to program better or parallel proces or ... .  In
almost all cases life is too short and too valuable to spend it trying
to persuade bits of silicon to operate reliably beyond their
guaranteed limits.

- Note that the "absolute maximmum" limits in the data sheet are the
limits below which desctruction will (probably) not occur. These are
NOT limits at which operation is guaranteed. People often try to
regard them as operating limits. They're not.

- Note that specs relating to body diode conduction always occur in
the absolute specs section - never in the operating specs section.

- Try to understand and take notice of advice before asking again.
