I run the bundle with the G.Skill Trident Z RGB (2x, 16GB, DDR4-3600, DIMM 288). There is a little more room for overclocking and the price is almost the same as the DDR4-3200.
I have 4x 8GB 3200 cl14 running. In this case, low timings are more worthwhile than high clock speeds, as confirmed by my benchmarks and the frame boost in games. However, only with an active DOCP profile.
