I have been doing some research trying to find the bottleneck in my system and have found very mixed responses regarding memory speed and FPS in Battlefield 4.

I am limited to 1600mHz with my mobo and have 1333mHz currently, I will be getting some 1600mHz shortly and will add my own benchmarks. Keep in mind my CPU (2500k) is overclocked to 4.5gHz and I am running two GTX660 in SLI.

Below is the information I have found so far.

This shows very little difference with his test setup, but the benchmark is done in single player which one can not compare to multiplayer.

Now this guy reports a 60% performance increase from 1333mHz to 2000mHz in bf4 multiplayer. this is where is gets confusing, most people say that bf4 multiplayer is very well optimized for multi-threaded gaming and this is why we see such a big difference in fps. Many people also report that the game runs much smoother with faster memory without there actually being and fps increase, But I guess I won't know until I test it in my own rig.
