At $450 for 16GB of DDR4-3200, G.Skill's Ripjaws 4 kit is very well priced for DDR4 of that speed, especially if you like the active cooling fans.  This particular kit is has timings of 16-16-16-36 with a 2T command rate. It also requires an impressive 1.35V to hit full speed, well above the 1.2V specification but in line with many of the other DDR4 enthusiast kits.  Indeed when Hardware Canucks started their overclocking tests they raised that to 1.4V and managed a variety of tighter timings with reduced clock speed; worth noting is that all of those overclocks were successful when using a 1T command rate.  Check out their full review here and don't forget to sign up for our contest!
