Best config for my RAM

Dear all,

The ram configuration is a bit confusing for me and I would like to hear your oppinions about my current situation.

I have 2 x 2Gb kingston hyperX @ 1600 C9 (KHX1600C9AD3/2G) and 1 x 8 Gb Corsair Vengeance @ 1600 C9 (CMZ8GX3M1A1600C9).

My current system:
OS: W7
cpu: Intel i7 4790k (stock rates at the moment)
mobo: ASUS z97-k
graphics: Nvidia GTX960
PS: hummer 750w bronze edition
HDD: 1,5Tb WD Caviar Green
SDD: 500Gb Samsung EVO 850

I don't know how to combine ram modules to get the best from them.

They are currently working as follows (CPU-z report):
