The cache hierarchy has flopped? People aren’t using swap?
NUMA also hasn’t flopped, it’s just that most systems aren’t multi socket, or clusters. Different memory speeds connected to the same CPU is not ideal and you don’t build a system like that but among upgraded systems that’s not rare at all and software-wise worst thing that’ll happen is you get the lower memory speed. Which you’d get anyway if you only had socketed RAM.
In systems where memory speed are mismatched, the system runs at the slowest module’s speed. So literally making the soldered, faster memory slower. Why even have soldered memory at that point?
