Strange thing I have seen is apparently it will hopld a performance level setting that's too low I was running at 5200 12x435 ram at level 6 approx. 540 4,4,3,4. Then I crashed upon rebooting I couldn't get into windows it would keep bsod. Finally got into windows and quickly set to diagnostic mode. I had noticed when I first opened memset it was @ per lvl 4 Coming back into windows in diagnostic it was slightly more stable. I tried changing memset to 6 then clockgening up with consistant crashes. I finally uninstalled memset and was 100% more stable. I reinstalled memset and it worked fine. I boot into windows easily at 4.5 so I started clocking again an hour later same sort of issue but was so bad since I was runnin in diag. mode already I had no savior. Load screen would work but as soon as the actual desktop was about to appear it would crash. I tried setting everything but to stock in the bios and still had issues. I finally decided to reload OS which I did at my same OC'd settings of 4.5 gig without a hitch.
