Which frequency to choose?

[Sudipto]

I have Intel motherboard Intel® Desktop Board DH61WW
The specifications for this board can be found here:
http://ark.intel.com/products/54876/Intel-Desktop-Board-DH61WW
The website says the motherboard supports 1600 MHz Ram chips too.

I have two memory slots and one has a memory chip.
This is the information about my RAM chip installed got through CPU-Z:

It is seen I have a DDR3 1333 MHz ram.
I want to install another RAM chip in the other slot.
So I want to know which type of RAM?
I am opting for DDR3, but I am confused which frequency to choose-1333 or 1600 MHz?

My current Ram chip:https://www.amazon.in/STARLITE-4GB-DDR3-PC1333-Desktop/dp/B01DBL0P5E

The 1333 MHz is stated more costly than the 1600 MHz chip of the same company which can be found here:https://www.amazon.in/STARLITE-4GB-DDR3-PC1600-Desktop/dp/B01DBL0LU8

Can I choose any one of 1333 or 1600 MHz?
And is it important that I choose 4GB and not 2GB?

Thank You.

Personally, I would match the RAM I have exactly after checking that it is on the QVL. Others may suggest buying a new set entirely. I do not see the point as the higher frequency is usually matched with more clocks so net effect is small. The move from 4GB to the 8GB larger amount of RAM will make more of a difference. 8GB total will handle current games. If sticks are same, you may find the now possible dual channel gives more improvement.
