Youre board only holds 8Gig of RAM in 2 slots, you have 4Gig, in 2x2Gig i'm betting. For 37 euros, theres nothing there worth your time.
You can get this and upgrade to another 4gb 1600 later if you will. They will work together as the 1600 will just be downclocked to match the other stick.

Corrosive wants to future proof you if you ever want another stick at 1600, you can use the full speed.
