What RAM to choose?

Hello,
On a new build I am getting Asus P9X79 pro with intel i7-3820 cpu and noctua nh-d14, and I don't know which RAM kit suits me the best.
Currently I am looking at these RAM kits:
DDR3 Corsair Vengeance Low Profile Blue 8GB (2x4GB) 1866MHz CL9 1.5V
DDR3 Corsair Vengeance Low Profile Blue 8GB (2x4GB) 1600MHz CL9 1.5V
Corsair Vengeance Low Profile 2x4GB DIMM DDR3 2133MHz CL11 XMP 1.5V Blue
KINGSTON 8GB 1866MHZ DDR3 NON-ECC CL9 DIMM KIT2 1.65V
DDR3 Kingston HyperX 8GB (2x4GB) 1600MHz CL9 1.65V
Which ram kit should I choose? Maybe I should choose different ram kit similar priced?
P.S i am going to oc my cpu
