Looking at the performance delivered by this set of G.SKILL Trident Z modules, it's clear that the modules do stand up well with the tighter timings. However, the secondary timings were loose enough that comparative performance took a hit when you look at the performance delivered by a similar kit from the competition. The looser secondary and tertiary timings let the modules overclock much further than the comparison modules, but you have to work a bit to tune these modules and the board for better performance. That being said, these modules will overclock to at least 3400MHz using the XMP 2.0 applied timings. To get there I needed to crank up the voltage to the modules to 1.5v to get the modules stable at 3400MHz 14-14-14-34. I cannot advocate pushing 1.5v through your modules, but G.SKILL has a limited lifetime warranty on the modules should anything happen.
