Don't forget that there are two regulators involved. First there is the
primary power supply's regulator down to either 3.3 or 5 volts. Then there
is the motherboard regulator down to the 1.7 volt range. If THAT one is
not up to handling the required oompf during certain CPU loads that is a
sure way to glitch the machine.
