I'm not using 1866mhz ram in my i5RYH but if those sticks are 1.35v, they "should" work. I've also seen reviews having Kingston Impact ram running at 1866mhz on their tested i7.
i7 should automatically configure ram to run at that frequency.
Hope this helps you.
If this is the model that you're talking about NUC5i7RYH the memory seems to be fully compatible, however since the NUC only supports DDR3L-1333/1600, if you run it at 1866 MHz it might not work properly or it might not work at all.
You can check the compatibility of the NUC5i7RYH here ARK | Intel® NUC Kit NUC5i7RYH
Also, you can check here Intel® NUC Kit NUC5i7RYH — System Memory some of the tested memory kits for the NUC5i7RYH.
THANKS. the memory works.
Was it plug and play? Or did you tweak BIOS settings?
It is specified by Intel that the NUCs run memory at 1600MHz at the most:
"If this is the model that you're talking about NUC5i7RYH the memory seems to be fully compatible, however since the NUC only supports DDR3L-1333/1600, if you run it at 1866 MHz it might not work properly or it might not work at all.

But according tot Legit Reviews, the (CL10) Kingston 1866MHz performed slightly better than the 1600MHz model and in the NUC BIOS the 1866MHz was being displayed:
Are you - or is some other visitor of this forum - knowledgable enough to shed some light on this matter?
I'm considering the HX318LS11IBK2/8 (same as yours, only 2x4GB) and would like to know if this would make any noticeable difference compared to the (only slightly cheaper) HX316LS9IBK2/8 (1600MHz, CL10). The CAS latency of the latter is one step better, but as far as I know that's no big deal.
Perhaps it's wise to play it safe and go for 1600MHz? Given this reply from Intel Customer Support (June this year):
"By reviewing both specs I concur with you in the sense that both are pretty much identical.
The main difference between models is the programmable latency; which does not represent a perceptible difference for a NUC unit.
The list of memory modules tested during development serves as a guidance for compatibility; but some newer memory modules that have the same specs might work as well and will not be listed in the provided website.
With this in mind, we can only recommend the modules we have tested; however, you can try on different modules with the same specs."
Last edit: Kingston states the HX318LS11IBK2/16 and HX318LS11IBK2/8 are compatible with the i5 and i7 (in a Mac laptop): Memory | Search
Note to Intel: please reconsider the way you inform your customers about "tested" memory, SSDs et cetera. The sparse, 'random' and not up to date manner of doing this, is causing much confusion and headaches.
Nice to hear that. In Europe the product code would be BLS2C4G3N18AES4CEU at the moment, as far as I can see.
Indeed, compatible with the NUC5i5 according to the compatibility checker (on crucial.com). I think I'll go for a 2x4GB pair of these, as CL10 is on step better (on paper) than the (presently) CL11 of the similar Kingston Hyper X 1866MHz SO-DIMM DD3L.
FYI: an owner of a NUC with i7 says here:
"I also tested various memories with more or less success. For example, my Kingston Impact 1866MHz works fine but the Crucial 1866MHz does not want to boot. Thus, for the time being I will leave the Kingston in it."
So maybe I'll choose the Kingston (the successor of the model tested by Legit Reviews):
"In any case, we were able to utilize the [Corsair] 1866 MHz (C10) kit without any problems whatsoever. The BIOS (with memory auto-configuration by default) automatically configured the memory speeds to the maximum rated value."
Resumé: on paper (i.e according to the producers), the 1866MHz Kingston CL11 and Crucial 1866MHz CL10 should work; the Kingston 1866MHz CL10, successfully tested by Legit Reviews, is out of production an nearly out of stock, I've seen no reviews about the Kingston 1866MHz CL11 on a NUC; one i7-owner has reported his NUC didn't boot with a Crucial 1866MHz; Anand Tech reported success with Corsair 1866MHz CL10; one NUC owner z_zk_z - see above - has reported success with the 1866MHz Crucial BLS8G3N18AES4.16FER.
"We learned from Intel that some 1866MHz kits will hang on boot due to the advanced SPD settings and this is why Intel does not officially support 1866MHz memory kits."https://communities.intel.com/message/311953

It seems there are different versions and/or experiences with the Corsair 1866MHz.
Confusion: is the NUC really running at 1866MHz... And according to Gintama7888 "it's lucky you didn't get the 1866MHz CL11 memory, cos that'll probably run bit slower than 1600MHz CL9 memory."
Bottom line: there is always some risk involved when you go for 1866MHz; if you want to play it safe, choose 1600MHz. At the moment, I guess I'll give the Crucial BLS2C4G3N18AES4CEU (1866MHz, CL10) a try; if it fails, I'll return it for the BLS2K4G3N169ES4 (1600MHz, CL9).
