Going to fiddle around and see what I can get.

I usually start high to ensure I lose no WUs and then gradually twiddle it downwards...
Yes more so than it impacts your NB its used to stabilize the voltage noise from the NB back to the CPU...


FSB Termination Voltage:
Source -> Line -> Component -> Short line -> Termination

the "lines" in this case are signal traces. High speed switching operations can cause reflections on the line (in essence, this is resonant noise caused from high-speed switching on the lines as the memory controller gates on and off to place data on the bus, nothing more than rising and falling voltages). clearly enough, the faster the signal switches (higher frequency memory) the more noise.
So to compensate for noise and reflection as the NB voltage and FSB frequency is raised so to must be the FSB Termination voltage be raised to mirror the NB voltage increase and the Frequency increase. This will in effect smooth the ripple effect caused by increasing on one end and not the other No exact formula here folks trial and error to find the best fit… (parts of this description were borrowed from FCG thanks for the contribution Chris)
