Only the small ones, X2.0 and T4.0s models arrive with one soldered module limiting to 24GB. Once you switch to real workhorses, even the T450 from 2015 supported 32GB which was quite rare for DDR3 https://www.reddit.com/r/thinkpad/comments/3kmlzv/people_keep_saying_the_t450_supports_32gb_of_ram/cza8ocq/ https://www.reddit.com/r/thinkpad/comments/3kmlzv/people_kee... and every T4x0 since then did because they sport two DDR4 slots. Same for T5x0. The P50, P51, P71 support 64GB. You were saying...?
