So I'm looking to get a second kit of RAM to go along with 8GB already installed.

The problem is, the first pair of sticks were Kingston HyperX RED Limited Edition, 1600MHz DDR3 - am I out of luck, or is there a way to get a pair that will be compatible with these?

Does it matter as long as you have the same speed (1600), if I were to, say, get HyperX Black?
