Hello Community, i have a quick question for you guys. I recently bought a 12 gb, 3 stick pack of corsair VENGENCE RAM @ 1600mhz. I installed it and overclocked the stock 1333 to 1600. Since one slot was not being used, i decided to buy another 4gb stick of Corsair VENGENCE ram @ 1600. Now, I was looking on CPU-Z and it says that the stick of ram that i installed is clocked at 667... All the others are at 800 -800 x 2(DDR) = 1600-. Please help, it's probably something simple but I need help D:
