I imagine you dump all the config registers of a running system, and then adjust everything that looks like some timing or drive strength parameter upwards till it stops working properly, downwards till it stops working, and then choose a middle value.
Do that repeatedly for every parameter pre-boot, and then use that config. Perhaps redo that every few hours or when the temperature changes.
