I think that your RAM timings are off. Are they something like 9-9-9-24? If so, calibrate them to the given timings for your RAM. I know that on Corsair RAM the timings and speed are on a label on the back of each module. The RAM you have is I believe the same as mine so set the timings to 9-10-9-27. Those are the order of the timings that I found. I'm not sure the difference in MOBO BIOS, so I cannot tell you exactly where they are. On mine, the DRAM Timing was under AI Tweaker. About halfway down, there was an arrow with some text saying "DRAM Timing" or something along those lines. Clicked on that, and it brought me to a page with the different timing controls. When mine was at default timings, the sequence was 9-9-9-24. I changed the second to 10 and the last to 27. It worked the second I saved and reset. Hope it helps you, and enjoy your computer!
