I got inspired by nefariouscaines post on his journey to ulimate air speeds here: an E8500 on a Asus P5N-e SLI post. Without his help I could never have gotten over my 3600mhz ceiling. All HAIL nefariouscaine!

I have kept a pretty good journal of what I have tried so far and wanted to journal it out in the hopes that it could be helpful to someone. I am not a great overclocker guru like nefariouscaine. I just read the forums around the web and try what is suggested by others. I will be back posting what I tried.

I play fps every night for about 4 - 5 hours. Cod4 mainly. I dont leave this machine on all the time. This is why I dont run ORTHO tests all night. I only need it to run 100% for short durations during game play, so I targe that usage when I consider it stable to me. Keep this in mind when you attempt these settings. During game play my cpu may go to 100% a few times, but idles lower than that.

What's with the timings of your ram? They seem way to high since you're running a Corsair Dominator that like high frequency with quite low timings.
