Can someone please tell me if they HyperX Memory Module HX426S15IB2/8 is compitable with the above stated NUC?
HyperX Memory Module compitable for NUC8i3BEH/NUC8i5BEK??
HyperX 2666mhz, 8GB DDR4 SODIMM, CL15.
2666 MHz memory should work OK on 2400 MHz system. So, you should be able to use it without problem. The opposite way may not work (i.e. 2400MHz memory on 2666MHz bus).
So, your NUC will not use the full capability of your SODIMM, but will work.
