My Ram:

I am sort of an overclocking scrub (overclcocked only without changing voltage), and was wondering if I could overclock my ram to 1800 or 2133. I tried going to 1800 but it caused me to bluescreen. Does anybody know the volatge or other things I would need to change to get a stable overclock of my ram?

Just don't go over 1.65v just start stepping it up a bit at a time till it's stable.
