Forget 2133mhz. NUC motherboards don't support it. 1866mhz isn't officially supported(yet), but, Intel has tested a few memory products at that speed and shipped some Broadwell CPU based NUCs to reviewers with the same. Unless you want to go into the NUC testing business, go to the memory manufacturers web sites and use its configurator or advisor apps to check to see if the memory you're interested in is compatible with the box you're interested in. It saves a lot of time and tears. I have a NUC 5i7r which runs very well with 16GBs of Crucial 1866mhz memory.
As for manual tweaking, I've read that one can go into into BIOS to change CL, etc. But, I've not done it myself. Today's boxes and memory should adjust on their own. That's part of what makes UEFI worthwhile.
Again, go to the memory manufacturers web sites to see if the memory you are interested in will work in the box youre thinking of buying. They have a vested interested in letting anyone interested know if what memory works with which boxes. If the memory isn't listed as compatible, chances are it isn't.
Already checked manufacturers sites but they only list 1600MHz models if you search for suitable NUC memory.
That's why I made this thread cos want faster memory, and hardware review sites run/recommend 1866MHz, 2133MHz.

I had no problem finding 1866mhz memory recommendations for mine. Also, if you find any reviewer recommending 2133mhz for a Broadwell NUC, I would be interested in seeing it. Everything I've checked is quite definite about 1866mhz being the current upper limit. The review you gave a link to is a year and a half old and was done with a 4th gen haswell based box a test bed. Also, they could only get 8GBs of memory to work, mot 16GB. Read the discussion below the review for more details.
Ok, thanks for that info. But I'd still pick 2133 over 1866 if it can run faster timing at 1866MHz since the price difference is less than $5.
16GB G.Skill Ripjaws 2133MHz 11-11-11-31 [Model No: F3-2133C11D-16GRSL] = can run 1866MHz @ 9-9-9 on NUC
16GB Kingston HyperX 1866MHz 11-11-11 [Model No: HX318LS11IBK2/16] = can run 1866MHz @ 11-11-11 on NUC
16GB Kingston HyperX 2133MHz 11-12-13 [Model No: HX321LS11IB2K2/16] = can run 1866MHz @ 10-10-10 on NUC
then I'd definitely buy the 16GB G.Skill 2133.
I am also looking for memory recommendations. I've just ordered the NUC5i5RYH and want to put 16GB into it. I'm interested in 1866MHz CL10 memory, as online benchmarks have shown a significant improvement vs. 1600MHz CL9 memory.
I'm having trouble understanding if the Intel memory recommendations mean they've tested one or two SO-DIMMs. What confuses me is there is only a single 16GB entry (composed of two 8s), the KHX18LS11P1K2/16. I find it hard to believe that Intel only tested one pair of modules. Can someone from Intel confirm if pairs were tested for the other modules?
My issue is sourcing 1866MHz memory in Canada for a decent price that is compatible with the NUC5i5RYH.
I can get my hands on G-SKILL, such as the G.SKILL Ripjaws Series 16GB (2 x 8G) SO-DIMM DDR3 1866 Model F3-1866C10D-16GRSL. I believe this is equivalent to two of the F3-1866C10S-8GRSL Intel mentions in the compatibility list, but I'm not sure.
So really what I'm looking for is what 16GB (8x2) 1866MHz memory have people used successfully with the NUC5i5RY*?
16GB G.Skill Ripjaws DDR3L 1866 CL10 worked fine according to user post I saw on www.legitreviews.com
I'm pretty sure G.Skill only have one DDR3L 1866 CL10 model, F3-1866C10D-16GRSL
I ordered 16GB Kingston HyperX DDR3L 1866 CL10, HX318LS10IBK2/16 and it should work fine to according to www.legitreviews.com.
I know this is a bit dated, but I just wanted to let you know I ended up purchasing 16GB G.SKILL F3-1866C11D-16GRSL memory for my NUC5i5RYH and never looked back.
I read that this was the same as the 10-10-10 timing version but cheaper, and artificially set at 11-11-11 for computers that needed that particular timing. I was able to customize the settings down to 10-10-10 and it's been working perfectly for a couple months. As some sites have suggested, after doing some benchmarks, there actually was a difference between 1866MHz vs 1600Mhz. Lowering the timings made a very small difference, but it made one nonetheless.
