It seemed to be a sweet spot for my setup and others on the DFI have had similar experiences. It's not to say that you couldn't get even better results with optimal gtl settings at 9x on your board. I just find that most people use 9x and leave gtls on auto, and when I did that I needed significantly more vcore to run stable.

Does onepagebook post on here? He's had a bunch of e8400s able to prime for long hours at ultra low vcore. I wonder if those chips have been taken up high and how they are now.

I hope you don't mind butting heads a little, it brings on more good discussion. I still think the case is not closed!
