Overclocking DDR4 isn't hard. Memory rated at the bottom, around 2133MHz, seems to have a lot of headroom, and memory at the top can be tuned by reducing timings. The memory and IMC are very voltage tolerant. While +0.5v VCCSA might seem scary, I have used it for a while with my 5960X without damage, but I would recommend around +0.3v for overclocking around 2800MHz.
While the stock voltage might be 1.2v for most kits, I would say you can safely go to 1.35v without much issue. The key to tightening some timings seemed to lie more with higher voltage than anything else. I would say that if you are looking for a solid DDR4 kit with a reasonable price tag, you shouldn't be afraid to go with a kit with a sub-2800MHz speed, as these kits seem to overclock pretty well.
The overclocking headroom might be due to the fact that DDR4 is set to go to much higher speeds than what we have today; a little clue can be found in some BIOSs where much higher dividers are listed (some go to 40X). With the improvement of BIOSs, memory manufacturing, and motherboards, I think we will see kits in the mid-3600MHz range within the next year.
While you might not be so keen on overclocking your expensive DDR4 kit, it is worth it to just make small enhancements like changing command rate to one instead of two, as things like that don't require much voltage increase. If you are benching a high-speed divider, and the system won't boot, just clear the CMOS and load the setting again; for some reason, this works once in a while.
The Crucial and ADATA kits both provide nice headroom, and make for great value purchases. The G.Skill kit is for those who want to compete in the overclocking realm, and I can say that they are very well binned. Overall, DDR4 proved to be a bit of a challenge, but the payoff is definitely worth the effort.
