What RAM chips to use for upgrading my T14s gen 1 AMD

So, I managed to find myself a buddy who does solder PC repairs for sport, and he agreed to solder new ram onto my T14s gen 1 AMD if I give him the chips, which I have great difficulty finding, because I have no idea which ones will be safe to use and where to eve nget them - I am going for 32 GB, and I know the board needs 8 chips (the current ones are SK Hynix H5AN8G6NCJ), so does anybody know which chips are used for the 32GB version, or which ones would work?
