1 out of 4 of my Corsair XMS3 DDR3 1600 4GB RAM failed. I ordered 1 stick. Do I need to order 2 at a time, or is just 1 ok?

1 out of 4 of my Corsair XMS3 DDR3 1600 4GB RAM sticks failed. I ordered 1 stick to replace the bad one. Do I need to order 2 at a time and replace one of the good ones as well, or is just 1 ok?

I have an Intel(R) Core(TM) I7-2600K @ 3.40 GHZ computer with 16GB of ram (normally).
