So I have the above CPU along with a gigabyte P35-DS3R mobo. So my question is what is likely holding me back from OC my cpu past 3.3 Ghz and 1.3375 volts. I know it's not ram as I have had it higher and tested that and am now running it with loose timing and 1:1 to make sure it's not the issue. So I figure it's either my cpu or mb. Right now I'm sitting on 1.3375 vcore and cannot get it past 413 without having to drastically up the voltage. At 3.2 Ghz I'm below 1.3 volts around 1.27 something if I recall and can hit 3.0 without a voltage bump at all. To get to 3.32 Ghz 415 FSB I have to raise the vcore up two steps to 1.3625V and that's higher than I'd like. My temps at 1.3625v and 3.33 Ghz @ load w/ prime95 is round 57-58 for all cores. Also I have played with NB voltages, fsb voltages etc and think I've tried just about every combination so it has to be I either have a cpu that can't go high or the mobo. So what does everyone think.
