I'm not sure that actually works on that machine, the intel specs list 32G max on the chips, which likely if its like some of their other designs caps the individual DIMM channel capacity. I've gone over the lenovo recommended RAM configs before when the intel spec supports it, but intel has been enforcing capacity limits on many of their parts (presumably in the low level binary firmware blobs which refuse to train DIMMs which otherwise might work) for the last few years. Even so, if you get it working, its the equivalent of 1/2ing your ram bandwidth. PS: what you probably want is a T480, same generation little thicker, with both ram slots, and the extended battery if one wants a beefier version.
