Isn’t the problem related to the capacity of current memory modules? So you can have, say, a 32GB module that’s vulnerable or a 8GB module that isn’t? (Assuming the 8GB module uses lower density DRAM chips)

A new 8GB DIMM module has about 1/4 the silicon area of a new 32GB module and the same density (often 1/4 the number of identical chips); only an old 8GB module, made with an entirely different process, would have larger and less dense safer DRAM cells.

Yeah, that's why I included the qualification
