Hello every one I am new to Overclocking and have done a lot fiddling with my Q6700 @ 3ghz(well 333x9). I almost pulled my hair out just to get that clock stable. I could run CPU core volts up with no help, even made things worse on prime95. I tried Vtt and NB bumps to stabilize. You name it and I tried it. Except one, the Ram voltage. it was always left on auto because I was not overclocking the RAM. Auto setting is 1.535v per bios so i left it because it was spec. So what made to difference? lets start with the problem.
With all voltage set to AUTO (all oc setting done in BIOS) I could always boot windows 7 . Even when I was at 3.3ghz (333x10). The problem came with Prime95 torture test. At 3,3ghz it was and immediate crash but no BSOD, just a Black screen and freeze. I thought I was the OC Sh**t on my overclock session until then. Anyway, I walked it down to current clock but still I would get the same Black Screen at 20min or so. Finally, if it kill the memory or not I was going to bump the DRAM volts. I stepped it up to 1.550v. One hour in Prime95 Blend no problem. It purred like a kitten at 48c.
One question is why did I have to do that to stabilize? I changed nothing to the ram setting expect I locked the Timing at 9-9-9-24. Any explanation?
