I have a question for these three corsair lp vengeance rams:

1.
This says it is dual channel.

2.
Doesn't say dual channel but has lower timing and same price.

3.
Dual Channel, $20 more, higher timing but higher clock speed (1866 vs 1600 for other 2)

What would be the best buy?
I prefer corsair only if there are any other suggestions.
Preference is towards 16 gb ram (2x8)
I have a z87 pro and 4770k
I plan on putting in a noctua nh-d14 in there so I need a low profile ram.
