With my SLI 780s, I am getting significantly more frames in BF3, even with the same low gpu usage of 60-70%. Previously I would have a minimum around 80-90 a maximum of maybe 150, averaging in the 100-110 range (at 1080p, 120hz). Now I am getting an absolute minimum of 100fps, a maximum of 200fps, and averaging around 130-140fps. Also, as noted in the comments above, the game looks a lot smoother.
I generally prefer lower frames on single cards to higher fps with SLI because of smoothness (although curiosity always makes me end up buying two cards!) - this is the first time that SLI has looked to me as smooth as a single card. Some of this increase is no doubt due to the marginally higher OC but the magnitude of the increase suggests that the faster RAM is also partly responsible. This wasn't a scientific tests so feel free to take these comments with a grain of salt but there seems to be real benefits to faster memory.
I feel you are seeing your framerate increases because of the memory frequency increase, because even though the clockspeed is slightly faster 200MHz is pretty marginal. It's like my Heaven Benchmark score or Valley score when I benchmark at 5.0GHz or 5.2GHz. Not much of an fps difference (only like 2-3 frames). Whereas your increases are closer to 10-20 fps. One thing I can definitely concur is the smoothness of games. I've always chalked it up as it just being nVidia drivers and my 670. But typically its in games where people are complaining about being in a certain fps range (around 40-45) claiming it's unplayable and although I might be in that same fps range. I can't even tell that I'm playing at 40-45 frames, to me it looks like 60 because it's running so smooth. That's because of the the higher frequency memory, not just the GPU.

Generally speaking the higher the frequency the looser the timings, and there is no way of getting around that. Finding a middle-ground between that is ideal of course. Although, with Intel it generally seems that higher frequency is more desirable regardless of timings.

after reading this I ordered 16gb of gskill trident X 2400mhz which I will probably receive tomorrow. I will play bf4 initially with my 1600mhz ram and note the differences after switching to the gskill tridents.
Can't wait to hear your results, you will enjoy your purchase. It will be justified even outside of BF4.

Here's some cheap G.Skill Ares LP 2400MHz. Better value in the end than 2133MHz, and will run fine on your 3770k:
