Getting compatible RAM with current

[Guest]

I currently own 12GB of memory - Mix and matched by Dell (it was in a prebuilt and I used it in my own rig) So I don't know the exact brand name.

 

I want to upgrade to 16GB, And I need to replace the two 2GB sticks with 4GB ones. (4x4GB)

However, I'm not sure what exactly works with what, do I need the same latency or are there other factors that must be matched as well? They are both 1600Mhz and CAS 11 Latency.

Here are some pics for more info:

 

I want to know if a kit like this would work. If not, could you suggest me something that would? Any help would be appreciated, as I'm not too experienced in matching RAM.

You should go for 2x8 for 16GB in dual channel. Also try to go for something with heat spreaders! Mix and matching RAM is not something I know alot about, but if I were you I would scrap your current sticks and get new identical ones

I don't really see the value in doing that when I already have one 2x4 kit, getting new ones would only raise the cost. Not too sure about heat spreaders either with the clearance of my CPU fan.
