I have an older model model (NUC6i7KYK) where after the BIOS update to v.0074 the SODIMM slot 1 (lower slot) is not working anymore.
I have 2x CT16G4SFD824A 16GB DDR4 RAM modules, and both work fine if only one is in the SODIMM slot 2. I used the same RAM modules prior to the BIOS update and it worked without any issues.
Once I connect something in slot 1 the PC is not booting anymore, after a few seconds it is just rebooting.
The display is not turning on, so I cannot access BIOS to see what is going on.
There is a solved post with the same issue but for a different (newer) model.
