I get this too, but it doesn't bother me, because 3200mhz is a huge overclock compared to the stock speed of 2133mhz and is not guaranteed to work. You can't claim a part is faulty because it won't run over spec.
That said, if you really want to rule out RAM itself being bad, test 1 stick at a time. Throw your usual plethora of memory test tools that you want at it (GSAT, HCI, AIDA, whatever) until you're happy and go to the next stick.
I'm going to guess you will find no problems.
Running 4 DIMMs in unison at that speed is tough on the IMC. Really tough. Sometimes it'll pass training, other times it'll just hang. Running 3070MHz C15-15-15-35 1T 4x8GB myself (ripjaws 4) and sometimes on reboot, it'll just hang, requiring a power cycle or AC cut to boot back up, sometimes with overclock failed; just 'save and reboot' without changing anything and it magically works. It's just part of X99 IMO. Don't like it? try z170 or broadwell-e, your experience may change.
also be aware that using a kit on x99 thats only qualified on z170 will cause manufacturer to not help you. they only support what they explicitly specify. using the kit in equipment not otherwise supported is all on you.
Also, on the other hand, using a 4 dimm 'dual channel' kit will not cause it to run only in dual channel mode if installed according to motherboard manual; CPU will attempt to negotiate quad channel if possible, and drop channels from there (some people mistakenly call it 'bad ram slots') or not post at all if the programmed timings are too difficult for the CPU to work with.
