I own the G.Skill Ripjaws X Series 8GB (2 x 4GB) DDR3-2133 Memory and notice it was set to 1600 in the bois so I switched it to 2133. I figured I would stress test my memory and I used Prime95 and IETU.

Prime95 could only stress 4gb out of 8gb and IETU could do about 3.5 out of 8. I tested it before and I switched it from 1600 to 2133 and I had the same results. Does anyone know why ??

Ok I just ended all the swapping of the ram ! I tried the two in the other slots, then I tried single card in the same slots then I tried single cards in the other slots. I also tried everything again with the other stick in the opposite slot. I booted up after each try in memtest and I would get the same results as I posted earlier :(
