I completely agree that ram frequency matters the most if you are using integrated graphics, but I completely disagree that current (and the past few gen) of intel CPU prefer timings.

I have tested my ram from 1333 to 2000mhz (it is rated for 1600mhz) and my best results were at 1866mhz (timings slightly loosened over 1600mhz, but when I go to 2000 I have to loosen the timings quite a bit for it to be stable). I am running an ivy bridge cpu like Nevakonaza.

Here is a review testing ram frequency and timings on ivy bridge (3770k). You can see for yourself that there are gains to be had. There are very few programs that run better on timings over frequency. That all said the gains aren't huge, and do fade out as you get higher (especially the jump from 2133 to 2400).

Choosing the Best DDR3 SDRAM for Ivy Bridge - X-bit labs

Maybe try the ram at 2133 and see if you can tighten the timings.
