Basically thats true !

Decreasing the voltage often helps, particularly if there is a
sensitivity to a voltage related function ! Heat is only one
possibility !

The problems with CPU's are down to geometry ! The overall voltage
rating is simply the average that a particular chip works best at !
Not all of the hundreds or thousands of circuits in a chip will work
best at a given voltage !
In addition to this the voltage regulation circuits on the mainboard are
not particularly precise. Plus or minus a few tenths of a volt doesn't
seem much ! But take into account that there may be 70 or 80 amps or
more flowing in and around the CPU. Add in any possible ground
currents that may be circulating !
Suddenly there becomes huge potential for instability of one kind or
another. All of which can be made better or worse by adjusting the CPU
voltage a little !
Generally lowering the voltage is more beneficial ! I have had machines
that benefit from an increase (Overclockers Excluded) but I can't bring
one to mind at the moment !!
