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

[Ozzfest05]

Ok Guys so I might need your help Currently Running this E8600 @ 4.5ghz on water chip is great runs fast with low vcore im loving it now I want to try some bench runs on water and with the Rampage extreme it seems to be finnicky like one dash of anything will cause it not to boot lowering voltages makes it more stable most of the time and once its stable its steel but you need to get there first so here is the question

is my math correct

VTT of FSB voltage = 1.43

1.43x0.667 + Y = VTT x 0.635

0.95381 + Y = 0.89535

Y = 0.89535 - 0.95381
Y = -0.05846
Y= -58mv and round it to -60mv

so I would set core 0 and core 1 gtl ref to -60mv ?

Im currently not using the GTL ref (auto) because its been stable rock solid at these settings but when I want to do some benching these values become more important at higher speeds.
