Does it make sense to buy 1866 Mhz ddr3 RAM if you're not going to overclock your 4790k?

I'm going to buy a 4790k but not going to overclock it (its stock clock speed is faster than the 4790, that's why I'm not going for the latter) The mobo I'm going to buy says its native clock speeds are either 1333 or 1600 mhz, and the cpu itself states a maximum of 1600 mhz. Does it make sense to spend money on 1886 mhz RAM if I'm not going to overclock anything on this build, ever? This cpu is a bad overclocker by the way since the tdp and heat raise sharply after stock speed so that's one of the reasons that I'm not overclocking it as I value a low tdp. If it's not too much to bother? What 16 gb sticks would you recommend ? Thanks in advance!

This is where I saw the native clock speeds of my possible mobos:

All can run 1866 and the CPU should have no trouble w/ 1866 simply enable XMP and select profile 1. 1866 will offer greater bandwidth and performance over base 1600/9 entry level sticks, (unless you go cheap 1866 with rather loose timings like CL11)

Planning to run on 1.0vcore huh? It sounds like the motherboard has your answer. You can't overclock the memory over 1600 mhz, so the only reason to buy 1866 memory is if you foresee plugging it into a different motherboard at some point.

..although if you're really trying to maximize power efficiency I think you'll need a board that lets you fine tune the power delivery — which is a Z97 — which would support 1866+. Food for thought.

I have a little trouble keeping up with the terminology but I assume the 1.0vcore is the default voltage (no overclock) heheh. Yes, that is the plan. What would be an example of such a board? I have a lot of trouble coming up with boards that meet the criteria I need. Most of the z97 boards on sale don't have an optical toslink out (which I use to connect to my audio receiver) so that pretty much narrows my choice to expensive z97 models. The ones I'm thinking about now are the following:

ASUS Z97-AR

vs GIGABYTE GA-Z97X-Gaming 3

vs GIGABYTE G1.Sniper Z97

But they all say their native RAM speed is either 1333 or 1600 Mhz. All of them can apparently be overclocked to accept memory up to 1866 and way beyond that (2933 Mhz) but I'm afraid that would probably mean raising the electrical consumption and/or losing stability. One of the reasons I don't want to overclock is I usually leave my PC on 24/7 and it will usually go like 8 hours straight every day doing either cryptocurrency mining or grid computing (world community grid), both very CPU demanding. 😀 and I wanted to keep things as cool and stable as possible. Coming from a build with a q9300 and DDR2, I will probably not be very affected by these stock speeds lol. Thanks for your answer!

XMP huh? 😀 Nice one! I have to check that out! The RAM I'm gonna get has CL9 timming 😀 It's this one:

KINGSTON HyperX Savage - 2 x 8 GB DDR3-1600 PC3-12800 CL9 (HX316C9SRK2/16)

Well, I guess I'll just have to change it from that to this:

KINGSTON HyperX Savage - 16 GB (2 x 8 GB) DDR3-1866 PC3-14900 CL9 heheh

Thank you very much! 😀

That's good to know! That sounds like some serious speed there! 😀
Good luck with your article!
