Yeah - I think the key here is 4x32GB specifically, not just 4 sticks. 128GB is much much harder on the memory controller, since those are dual-rank memory modules (or pseudo-4R due to how DDR5 is wired compared to DDR4), and we got 4 of them. So even 4,800 is far from guaranteed in this situation, on any platform atm, and it’s unclear at this point if and when the situation will improve, barring larger memory modules in 2x48Gb and 2x64GB configurations (which would be much easier to run) or the next gen of chips with stronger MCs.
