Difference Between These Memory Sticks?

[steelteal]

Hi, can anyone tell me what the difference is between these memory sticks?
1. Corsair Vengeance 16GB (4 x 4GB) DDR3-1600 Memory
2. Corsair Vengeance 16GB (4 x 4GB) DDR3-1600 Memory
3. Corsair Vengeance 16GB (4 x 4GB) DDR3-1600 Memory
If it helps, this is what it is going in: My build.
Thanks.

First 2 is just the colour. The third one is low-profile so as not to interfere with large CPU coolers.
Otehrwise they are exactly the same. Get the low profile RAM.

One is a low profile kit and the other two are just different colors of the same model.
