New build won't accept 4th stick of RAM?

New build initially wouldn't accept my RAM at all. I bought a higher frequency since the Z87 has XMP technology and this RAM was on sale. I bought 4 sticks to make 32GB. I was able to get the new build to recognize the RAM if I only put in one stick at a time and rebooted. So, insert first stick > boot > stick accepted > shutdown > add second stick > repeat... This worked up until the fourth stick was added. It just won't take it. I know a decent amount about PC's but I'll admit I don't really know much about RAM itself. I know the stick is good because I've traded it out with another and it works. What can I do to get it working? Do I need to return them and buy something different?

Specs here:

try to plug the remaining dim in slot 3 (to make sure it's not a problem with the ram module itself). if it doesn't work in slot 3 either the module it dead and you can warranty it.

if it does work, the ram itself is ok. you can try to plug in 4 and leave 3 empty - that way you find out if the slot itself has issues or the using 4x8gb. for either of them, a bios upgrade for the motherboard might fix it... the frequency seems a bit low 666Mhz also, try setting it auto instead.

Well, everything seems to be screwed up now. I tried removing the sticks and putting the "fourth" stick in by itskef to see if that would work and it didn't. Now I can't get any combination of stick or sticks to work at all. RAM is getting returned. New build is dead for the time being. Not happy. :(
