Yes they spent those costs to switch from DDR4 to over-priced DDR5 and I suggested the cost could be spent on adding more DDR4 channels instead.

The problem is if DDR4 was viable here it would also be absurdly expensive. There’s no world in which we survive this demand without a corresponding increase in supply. It’s not like there are zettabytes of spare cheap DDR4 sitting around.
