Mmm... let's just say they control the way some voltage signals are handled. Using your PLL as the base to multiply, the value after the multiplication should be quite low, but don't let it be too low or too high compared to 2/3 of your FSB Termination voltage. It's trial and error, though, because the real voltage may not be what you set in the BIOS. You can try upping your vCore to compensate for the error in real voltage, though. Also try to consider (vCore x vCore ref)/(vNB x vNB ref). It seems the closer you are to getting 1 and as long as (vCore x vCore ref) is less than (vNB x vNB ref), the system is more stable. It still locks up on me quite a lot at 500MHz FSB though.

Edit: And this may explain why upping the vCore and vNB alone will make the system more stable in some cases... just because as the numbers get larger, they get closer to 1. Disregarding vFSB and vPLL, which are handled automatically by the motherboard (which, I think, also tries to get them to match as close as possible) we have (really high vCore) / (really high vNB) = somewhat... closer to 1. This might also be why on some motherboards, when vCore is settable to 1.90v, vNB can also be set to 1.90v.

I'm still not so sure... but at least that's how I understand it after trying to digest a whole bunch of articles about VTT and stuffs...
