I would like to ask why there is no opportunity to order 16 GB of DDR4 RAM (2666 MHz) in one piece for Optimus X when it is possible to get 16 GB RAM with lower frequency for this model (2400 MHz)?
Why do you only want one stick? To add more later?
I think I read someone saying on the forums there were compatibility / stability issues with faster RAM in some Clevo chassis and PCS were awaiting an updated BIOS from Clevo... though I might have imagined it.
