No. DDR3 can handle up to 1.9v, though you might want good case airflow if you intend to go that high. You will not get much from pushing that much voltage through your DIMMs anyway, and the IMC might not like it much either.
Regardless, I regularly use 1.7v in my Silicon Motion DDR3-2400 2x8Gb kit, and have done so since last November.

Personally I wouldn´t pay a penny extra for tighter latency as the bottle neck is elsewhere.
I disagree, at least based on Kaveri benchmarks that have shown the effects of memory latency to be quite significant. If he isn't using the iGPU for graphics, he'll rarely see any difference from higher clockspeeds at the expense of timings. Here are some simple tests I ran using SuperPi mod 1.5XS and y-cruncher at different memory and NB speeds with an A10-7700k @ 3.4 GHz (no turbo):
32M: 19m 15.956s
32M: 19m 18.439s
32M: 19m 2.346s
DDR3-1600 7-11-11-28-1T NB 2000
32M: 18m 54.628s
DDR3-2400 10-12-13-2T NB 2000
32M: 18m 31.939s
Now, for my money, I'd rather have DDR3-2400 CL10 than DDR3-1600 CL7, but the two are close enough that most people would not see a difference. But, as you can see, reducing timings can make a pretty big impact on performance.
DDR3-2133 CL9 would be about the same as either solution.
