Very good product, readily acknowledged in 1333 but thanks to the 2 profiles XMS is happening in 2400 in a nod via the bios. G.Skill data in 10-12-12-31-2N it work perfectly in 10-12-12-31-1N. and 2400. Removable sink is more, I had to remove it because of the huge size of my cooler. CAUTION not to lose the little tiny slices by removing the words sink. It exudes quality workmanship and always guaranteed to G.Skill life that I have been able to test on other rams of the brand and that I trust this brand In short, go =)
