Every type of DRAM is ultimately made at the same fabs, so if one type is suddenly in high demand then the supply of everything else is going to suffer.

Wait, really? For CPUs each generation needs basically a whole new fab, I thought… are they more able to incrementally upgrade RAM fabs somehow?

Not quickly but if somebody puts enough money on the table, the fabs change too. All about cost and return. Micron just axed their brand crucial (end customer RAM and SSD) because they will only sell to database centers from now on.

Crazy times.

The old equipment is mothballed because china is the only buyer and nobody wants to do anything that the Trump admin will at some point decide is tariff-worthy. So it all sits.

Essentially yes, not necessarily equivalently but every type has increased substantially
