hello everyone. i want to put a CORSAIR TW3X4G1333C9 and A-DATA with the same speed - 1333 mhz. can i do it? or better not to? also, how do you like both of them? is A-DATA any good? corsair is my one of the most trusted companies in memory market, as well as kingston and OCZ, but the last 2 are expensive (120+), but this looks ok.
