6x1GB mixed HCF0 and Micron D9GTR liked 0.35-0.45v difference
3x2GB Corsair Dominator GT Elpida 50nm based likes 0.20-0.28v difference - hence the general trend to need more cpu vtt than samsung hcf0 but handle CAS7 timings higher than others

Those seem to be pretty good examples. The voltages are a balancing act. The difference between VTT and DRAM voltage affects stability. And to a lesser extent the amount of VTT influences the needed VCORE for CPU stability. Once past general guidelines it's trial and error to what each system is happy with.
