Many people (and I mean *many*) who have tried the 2400MHz HyperX memory have had major problems. My recommendations are to (a) replace it with 2133MHz memory (the small increase in memory bus speed is *not* going to get you any real improvement in performance - but it can raise the noise on the bus to intolerable levels) and (b) replace it with memory from another vendor (I see *way* too many people having issues with HyperX memory in general).
Hope this helps,
Please let me know how it goes after you try a new ram, at this point I suggest you to try one of the ram validated by Intel from the link above.
Bought another pair of memory and it arrived yesterday: Amazon.com: Crucial 32GB Kit (16GBx2) DDR4 2133 MT/s (PC4-17000) SODIMM 260-Pin Memory - CT2K16G4SFD8213: Computers & Ac…
Seen it reference in a thread here and it's working fine now. Managed to get my display and ubuntu installed.
Thanks for the advise !
I've got exactly the same problem.
There's a workaround that works for me:
- Borrow a stick of DDR4 2133Mhz from some known working system, just so that I could boot the NUC to the Bios
- In Performance / Memory tab, change Memory Profile to Manual - User defined. Set the Reference Multiplier to 1.33, and Multiplier to 16. The rest was left as default, and the Timing could still be Automatic.
- Save Bios setting and turn off the NUC, and put back HyperX RAM.
- Now the system would boot up OK.
As I searched around and found that many others encountered the same issue, I would like to suggest to Intel: please provide us with a Bios Update, where the Default / Automatic memory profile is a SAFE one, running the memory at the speed that's SUPPORTED (e.g. the default option should force this HyperX RAM to run at 2133Mhz instead of 2400Mhz. Users should manually set the RAM to higher speed if they want to. And if the new RAM setting cause the system fail to boot, then the setting should be reverted to the SAFE configuration AUTOMATICALLY.
This Skull Canyon NUC is a GREAT system, but the trouble with the RAM marred the experience quite a bit (admittedly it's due to lack of research on my part before buying the RAM). If Intel could provide an update, the it would be PERFECT.
Unfortunately, while it might make some sense in this case, I rather doubt that you will see this happen. There is an across-industry expectation (I can't call it a requirement but it is pretty darned close to being one) that the configuration that is provided by that memory (i.e. specified in the XMP Profile(s) included in each DIMM's SPD) will be used by default -- regardless of whether this is going to be stable or not.
