I just put Crucial 2 x 16 GB DDR4 2400 memory on my 7378 (I was in doubt but your PC had one 16 GB and thus I concur that all memory pins are supported). It booted and BIOS shows 32 GB memory. Windows 10 memory test passed. I used the 2 x 16 GB set so that SODIMMs are matched. Dell Support should have said that it works under what conditions, rather "try it". Thank you for asking. Otherwise I did not try.
