Yes, a pic of your settings and such would be helpful. Those sticks utilize Samsung UCCC chips and from what results I have seen, should clock quite well. However, UCCC absolutely does NOT like tighter timings at all. Some people are able to push down to 3-4-3-8 on other brands, but for the most part Corsair's can't really be pushed down at all. Also, best voltages are 2.6-2.8, sometimes 2.9.
