Not sure if you mean the Gen 1 or Gen 2 T14s, but as I pointed out in the article, both the T14s Gen 2 and P14s Gen 2 can be configured with up to 48GB of RAM, albeit with the lopsided arrangement of 16GB being soldered on while the remaining 32GB are in the upgradable slot as a regular SODIMM.

I really feel an arrangement like this should be outlawed, it really makes little to sense to not have both be regular, upgradable SODIMMs like almost every other normal laptop.
