I got my chip to 3383Mhz with 1.55v and my Zalman 9500 (suicide shot only LOL ). For some reason it won't boot with more voltage. Air temp was about 15C I guess...

I have a cvf file of that score, but CPUZ sometimes doesn't read the mobo details and some other crap needed to get a validation.

3.5 won't be easy for you (or me) I think, so good luck!
