RAM for i7 4790K on Z97 mb

[andiron]

to answer all of questions in one sentence: either one of those kits will be fine and you will not be able to tell the difference between the two with a discrete gpu. ive used corsair for several years on customer builds and they make a fine product. ive not used patriot that much but they have a good reputation as well. usually if one maker can get 2133 with 1.5v and the other has to push 1.65v then one has better silicon in the chip(more stable at lower voltages).

its up to you and how much you want to spend. on these newer systems i find that 1866(even with igpu systems) is a happy medium but you may find that higher freq memory costs about the same or maybe a little more and it may be worth the money for that little boost.

good luck

Yep...you pretty much anwered all of my questions...at least for all intents and purposes . And I think it's especially interesting to think of how voltage is associated with the quality of the silicon.

After the last post I went back and scoured pcpartpicker and found that the price tends to go up pretty steep from 2133 Cas10 to Cas9...or to a 2400mhz Cas?. Corsair also makes another interesting kit...the Vengeance Pro 2133mhz at Cas9 at 1.6v. But this comes at a pretty big jump in price so I will probably stick with my original choice. Thank you for the help! I wouldn't even consider this build were it not for the kind people I have met here on this site.
