Alienware Aurora R5 - Ram Upgrade Question

I have the Alienware Aurora R5 with 2 4GB DDR4 2133 PC4  RAM sticks.

I have been wanting to upgrade my system with 2 more 4GB sticks. I located the right type of stick the 288 point DIMM stick but I can not find on the stick themselves or in any of the diagnositc tools if the Cas Latency, Timing, or Voltage are compatible with the current RAM inside my desktop.

The ones are chose are the CORSAIR Vengeance LPX 8GB (2 x 4GB) 288-Pin DDR4 SDRAM DDR4 2133 (PC4 17000) Desktop Memory Model CMK8GX4M2A2133C13R.

• DDR4 2133 (PC4 17000)
• Timing 13-15-15-28
• Cas Latency 13
• Voltage 1.2V

My system specs  ( that I know)

Intel Core I7 6700k @4.00ghz

GeForce GTX 1070

Ram Sticks say 4GB 1Rx8 PC4-2133P-UA1-11  - Samsung Brand

As a secondary question. When I get my new RAM in. Inside my PC there are two slots that are white and two that are black. The two samsung sticks that came with it are in the white slots. Should the new two go in the black? Or does that matter?

If there's any other info I can try and get it. But I am not exactly the most computer saavy. Hence why I purchased an alienware instead of buying my own haha.
