Well I made a little progress today.
I left the memory at 1333mhz unganged, 9-9-9-25-34 2T (as stated by the SPD) and let memtest86+ run overnight. After the 5th pass and
10 hours, finally it showed some errors towards the end. Yay, results! I opened the computer up and tried moving the memory around and noticed that the heat spreaders on the g.skill ripjaws is laughably flimsy, as if part of them had already started to come off. I'm guessing I may finally have faulty ram after all and/or inadequate heat dissipation. Perhaps this explains why I was only getting BSOD after a long uptime.
As far as 1600mhz it only ran this way for a few hours to check the memory at that speed, the vast majority of having this computer its been run at 1333mhz. But with what you said, is my CPU suspect now as well?
Thanks for the help along the way, I will try to get a different brand (more money spent, ugh!) since I can no longer return the memory at this point. I will RMA it and hopefully be able to sell the returned sticks. I guess lesson be learned, return
everything at the first sign of trouble when building a new computer regardless of your own diagnosis!
Regardless of this, I will try the individual sticks as well to see if there was one being the culprit.
