That's why I said it is what works for me, and I'm simply offering a suggestion for him. FYI, my system is not even stable for 10 mins at 400FSB and I can't even post at 450 without the skews being tuned. If I have the correct GTLs tuned and not the skews, I still can't get near 450FSB, so from my experience, the skews have a more profound effect than the GTLs, I'm not saying it's written in stone for every user! The GTL equation certainly isn't either!
