> DDR5 SO-DIMMs are not compatible with DDR4 SO-DIMM slots—just something I learned on this project... I knew full-size DIMMs were incompatible due to the extra on-stick ECC circuit on DDR5 RAM, I just didn't know the same applied to SO-DIMMs. Obvious in hindsight, but something to keep in mind.

Umm... what?

The incompatibility between DDR4 and DDR5 DIMMS is also enforced by a physically different notch and slot. It's always been this way.

Sure, but it's only obvious once you know that. Given that the N100 itself supports both DDR4 and DDR5, I think the confusion is entirely understandable.
