My Northbridge is perfectly stable at ~1.4V (1.39V set in BIOS), with a dual core and two sticks of RAM. Since his 2GB has less address space for the MCH to handle than my 4GB, there's no way he needs at least 1.47-1.51V for stability. This is using a 400MHz strap, but I think a 333MHz strap works fine too. My RAM isn't so good, so I use a 400MHz strap and lighter timings and performance levels for that stuff.
Also, my E8600 is running on a Maximus Formula at 4.5GHz with the FSB Termination at only .05V above the Intel recommendation of 1.15V. It's set to 1.3V, which results in ~1.2V. It does 4.0GHz at stock FSB termination. It may even do 4.5GHz at stock FSB Termination. I don't know. I haven't tried it.
I was under the assumption that FSB termination and CPU PLL is really only important for quad cores, at least not on dual cores until really high FSB speeds.
I do have Loadline Calibration enabled. It lets me get away with less voltage at idle, and voltages seem to stay the same under load and at idle (it'll go up from 1.376V to 1.384V every here and there, but it stays under 1.4V I have set in BIOS for it never to go over).
Am I missing something? I don't understand the every detail of every setting, but my values are way lower than you're suggesting, and it works.
