Yeah, It took me 1.4125v to be stable with HT on for 8 threads. I had to turn off turbo mode because it would instantly bluescreen when trying to increase the frequency to 4.2 ghz. I also had to use a multi of 19x because 20x200 would boot to windows but instantly crash When I ran Prime95.....I am using the same memory jasonelmore has also.....
