16GB DDR3 1600MHZ too slow for a new i5 4690k build?

Not a huge problem. Benchmarking has shown that you only gain marginal overall system performance in games with faster memory.

CAS of 9 is fairly good for 1600. You can get 1866 with a CAS of 9 for about ten dollars more. 2133 with a CAS of 10 for another ten. 1866 and 2133 fairly easy to deal with using XMP profiles.

2333, 2400, 2666, 2800, 3000, 3200, 3400 might require voltage tweaking and you may not get to the rated speed. Basically a lot of overclocking.

Haswell likes 1.5v so I tend to stick with that rather then risking stability by running 1.65 through the memory controller. (1.65 is what a lot of the high speed DDR3 need to reach those clocks)

Thanks for informative answer. I picked up that kit for about $90 CDN all in a few months back so as long as I have no problems I think I'll stick with it. Looking to overclock up to 4.6k - 4.7k , do you foresee any issues?

Stability can be increased a little by using a 2x8GB kit instead of a 4x4GB kit. The two extra chips are powered via the CPU, so that increases the core temperature a little.

Each CPU is a little different, but most people are reporting 4.6-4.7Ghz with Haswell refresh chips. What kind of heat sink do you have?

Also not to say that your ram can't run faster or have the timings tightened up. If you do increase the voltage you might be able to lower the CAS or increase the clock a little.
