Strange link between cpu and fsb voltage??

I've been doing some overclocking lately of my Core 2 duo E6600 and have noticed some very strange behaviour that I don't clearly understand at this moment and I'm wondering if anyone has an explanation.


Table
405mhz fsb - CPU 1.5725volts - Default FSB voltage = stable overclock
405mhz fsb - CPU 1.5325volts - Default FSB voltage = unstable overclock (freezing)
405mhz fsb - CPU 1.5325volts - 1.50 FSB voltage = stable overclock.

With my setup (watercooling) as I drop CPU voltage down to a point where the cpu gets unstable at a set FSB (405), if I up the FSB voltage while keeping the decreased previously unstable cpu voltage, the CPU stabilizes and I'm not sure why this is. I upped my FSB to 1.50v, and turned down the voltage from 1.56 to the usually unstable 1.53volts on my Asus P5W DH... does anyone have an explanation?

I would check the actual voltages with a digital multimeter before I tried to make any guesses based on bios settings. Have you checked these voltages in the bios monitor and compared them to readings with ASUS Probe or some other utility?
