I've asked them for a table of values showing what QPI PLL voltage is set per different CPU PLL settings.

It seems 1.89v CPU PLL is probably between 1.14 and 1.16v QPI PLL. Raising my CPU PLL to this value gives me about the same stability/voltage settings that I got on my friend's x58a-ud3r with my chip.
Can we can measure the the QPI PLL at different CPU PLL and make this table alone since Asus don't want to "share" it ?
