Also does the VTT really matter as long as it correlates with the GTL?

Well, as long as you don't go much over 1.5 V and keep GTL's to 0.667xVTT, you should be fine. What I usually do is multiply my desired VTT voltage by 0.667 to get my corresponding GTL voltage. There's a look-up table for the BlackOps that corresponds the BIOS settings for the desired GTL voltage for the corresponding VTT voltage. I will resort to adjusting GTL's only when one core is failing and the other three are passing. I have done the same with northbridge voltage and northbridge GTL tuning. I have also used GTL's to lower Vcore, once I have found stability at a certain Vcore. GTL's are for fine tuning.

What are mainly is everyone running for NB voltage for 420-430FSB range?

It depends on your board, chipset and how much RAM you are using, 2x1G, 2x2G or 4x1G. It also depends on whether your dimms are single sided or double sided. Single sided dimms are easier to run than double sided.

On my board, with 2x1G DDR3, I use about 1.5V NB for a stable 8x450. For 9x412, I can use 1.46 V NB for both 2x1G RAM and 2x2G RAM. The cooler you can keep the NB, the better off you are in terms of stability.
