QPI/VTT voltage

[CrossStealth]

In order to get a stable overclock I need a very high QPI/VTT. It is probably due to the amount of ram I have. 12gb
Now the question I am asking is

1. Is there any other value I can add voltage to that will allow me to lower my qpi/vtt?

2. Is there any way to see what the current qpi/vtt is after the vdroop? Maybe it isnt as high as I think it is after the vdroop

I doubt you will need my hardware config for this question but just in case

GFX - Galaxy GeForce GTX 470
RAM - G.SKILL Ripjaws Series 12GB (3 x 4GB)
PSU - CORSAIR CMPSU-750TX 750W
...HDD - Western Digital Caviar Black 2TB
Case - COOLER MASTER HAF 922
Mobo - GIGABYTE GA-X58A-UD3R
Cooler - Tuniq Tower 120 Extreme
CPU - Intel Core i7-930

More Vcore = less VTT. It's not really related to the RAM, if anything you'd need more DIMM voltage but you shouldn't really.
