It appears that half of the memory is soldered to the board. That was also the case on my laptop mentioned above. It came with 4GB soldered, and 4GB in a slot. Why? I don't know. I was able to swap the 4GB with an 8GB and somehow it's still running in Dual Channel mode per CPU-Z so I guess it's no big deal, but I also find it odd.

The Lenovo Thinkpad X13 Gen 1 (AMD) has all memory soldered and no SODIMM slots according to its specification: https://psref.lenovo.com/syspool/Sys/PDF/ThinkPad/ThinkPad_X...
