How to set up GTL Ref Values for 45nm & 65nm

[Cibic]

Guys, I've been reading but I don't fully understand it. I have never done maths in english.

MB: Asus Striker II Extreme v1104 Bios
CPU: Q6600 at 3.6GHz, 1.46v
VTT: 1.44v (actual 1.46)
NB: 1.55v
PLL: 1.6v
According to Seban's excel file and
from what I gathered:


Doing the maths I get 46mv that means I should set the values and then work my way down or up?
and each time I get a failure but I must keep 1 and 3 40mv below 0 and 2.

eg.
GTL ref 0: +50mv
GTL ref 1: +10mv
GTL ref 2: +50mv
GTL ref 3: +10mv
NB: +50mv

Which way is it correct?
What range should I be and if none of the ranges work, that means I need more volts somewhere?
