Hi JeanLuc7, do you get the expected three blinks without memory?
Hopefully the suggestions given here will be of help: Re: Crucial Memory incompatibility With NUC DC3217BY?
sorry for being not precisely. I get the three-times blink code if memory is NOT installed. In this case the board does not turn off. But when I insert the memory, it shows the behaviour described above. Then it even does not matter if it is a 1.35V SODIMM or a 1.5V one.
Thank you for the link, but unfortunately in my case I even do not get into any BIOS screen, because the system simply turns off. So I cannot change any configuration then. Without memory inserted the screen stays dark.
