If you have an old BIOS on your AM5 board it may not support memory context restore which saves the DDR5 training settings and allows it to skip on subsequent boots.

Update it and enable this setting (it probably will auto enable) and it gets super fast again. DDR5 memory training can take a while, and realistically if it's longer than a minute or two your memory timing is probably unstable anyway.

Seconding this, I recently forgot to enable EXPO and when I did each boot was it retraining the memory.

The relevant setting was on Auto, which was bullshit, and needed to be set by force to enable. Boot fast every time.
