Need help finding memory

[Running Raptors]

I want to upgrade my system memory to 16gb but I can't seem to find an exact same memory module that I currently have. I bought only one at the time as it was the only thing available and it was for $42. I want to run them in dual channel and I think they need to be identical modules for that to work. Here are some pictures of my ram. It would be great if someone could find it.

A bit cheaper at Newegg but it says they're out of stock.

Will it still run in dual channel even though they don't "look" identical as it like in the back there are 8 little small black squares. Lol don't know what they are called.
