I have bought this NUC and the first thing that I have done is to install Windows 10, update Windows 10 and update all the drivers from intel tool. Sometimes the NUC gets freezed, surfing the web, listening music with Spotify...
I have executed Windows test memory diagnosis tool in advanced mode and gets freezed at 21% of first step (more than 6 hours) with all modules configuration (both connected, only one, changing the memory bank). With MemTest give me a lot of errors. The RAM settings in BIOS is default. I don't know if the problems is with the RAM or with the Intel NUC.
I was about to write the exact same question and then I came across this thread.
The set-up I use is NUC8i7HVK with HX424S14IBK2/32 (Intel Validated).
It was impossible to successfully install Windows 10 using default BIOS or XMP settings or completing the memtest without errors.
Looking at the RAM settings and comparing it with XMP profiles of other HYPERX DDR4 SODIMM-s, rated for higher frequencies revealed that XMP profile for the ones rated for 3200 have 2400 XMP profile set at 14-16-16, while the ones rated for 2400 have 2400 XMP profile set at 14-14-14.
Using manual/user defined settings set at 14-16-16 (even 14-15-15) seems to function properly to the extent tested, which is memtest-ing through default 4 cycles, without returning any errors and successfully installing Windows 10, Performance and BurnIn testing it with trial versions of PassMark Tools without crashing.
Prior to using more conservative RAM settings with latest 0054 BIOS, I also tested RAM modules individually, swapping them between slots etc... without success.
Unfortunately, I have no way of cross testing NUC or RAM to determine which is at fault; it could just as well be the unfortunate combination, but I was relying on the Intel validation info prior to purchase.
I checked the BIOS version and it is the 54. I did a clear CMOS and the problems continues. Chatting with the shop, they are going to send me new RAM modules on monday. I'll test it and give you news.
@RLesnik. I have the same issues. The first time, windows give me a lot of problems to install, but i created a new USB-Booteable with all the updates from Microsoft and works. I am going to test your RAM config and update the post.
