Magnificent ThinkPad model. Too bad the soldered-on RAM precludes the possibility of using ECC modules. The Pro version of the Ryzen CPU means ECC compatibility.
afik not a single ryzen laptop uses ECC from the factory and documentation on compatibility is pretty horrible; this is the only thing stopping me from making the leap.
Supposedly someday we're meant to have DDR5 with ECC built in. I've been waiting for that day as well.
