Why does loading take so long when teleporting in Metaphor ReFantazio?

Teleporting from school to the city felt endless, with the loading bar crawling. I reseated the RAM sticks, thinking it was a loose connection, but it stayed in single-channel mode. I checked the GamePP Hardware Sensor Page and saw bandwidth below 35%. I moved the Asgard Hel sticks from A1+B1 to A2+B2. Bandwidth utilization jumped to 88-95%. Loading times dropped from 15s to 6s, fixing the narrative flow instantly.
